(8/15/2018) InSinkErator: CPSC Report ID 20180516-FF980-2147387938
The purpose of this response is to reply to the May 16, 2018 online submittal of the above-referenced consumer complaint.
The subject dispenser is a replacement Service Tank that was likely installed for slightly over 8 years. The original tank assembly would have been supplied with a 3-year warranty; any remaining time period applicable to the replacement tank when replacement offered through InSinkErator’s warranty handling process. InSinkErator has no knowledge concerning the previous tank and how/why this replacement tank existed at the reported address.
This InSinkErator hot water dispenser is constructed in compliance with UL Standard ANSI/UL 499 covering Electrical Heating Appliances. A standard 120-volt grounded electrical outlet is required; the type of outlet utilized (standard, GFCI, or AFCI) under the sink for this particular installation is unknown. InSinkErator reviewed the tank assembly finding there was evidence of water seepage from the lower portion of the tank assembly resulting from development of tank corrosion and very minor seepage at the Inlet/Outlet fittings atop the non-pressurized tank assembly. The evidence had been disassembled to some extent prior to return and the drain fitting was missing. Electrical testing of the assembly indicated there was no remaining electrical continuity by which the unit could continue to heat water; this unit ceased to function.

The product, in the report: Insinkerator Instant Hot Water Dispenser

We smelled smoke in the house and investigated to find the source to be the Insinkerator Instant Hot Water tank under our sink. Unit was smoking and hot. I immediately disconnected power, then disconnected the water lines so I could move the smoldering tank to outdoors. Once the unit had cooled I took the cover off to see what had happened and found that one connection to the heater had overheated and burnt the connection, wire, and was melting the Styrofoam tank insulation. Thankfully we were home and able to locate this problem before it potentially caused a house fire. This information has been provided to the manufacturer as well.

The purpose of this response is to reply to the November 15, 2016 submittal to the CPSC of the above-referenced consumer complaint.
The tank assembly was returned and tested at InSinkErator. It was determined that after slightly less than 5 years in service, the check ball in the expansion chamber was not fully sealing. This results in aeration and would explain why the consumer was not able to rectify the sputtering water flow when actuating the faucet to draw water. This condition is likely the result of mineral deposit buildup or debris coming from the water supply. InSinkErator Customer Service communicated this as one possible explanation eleven days prior to the 11/15/2016 Report Date and the consumer seemed to be satisfied.

The product, in the report: Insinkerator Instant Hot Water Dispenser

2 years ago I purchased a In sinkerator instank hot water unit from Home Depot. Model # SST Serial # 06028884401. The other day, August 29th 2014, we noticed smoke in our kitchen just as we were getting ready to leave. After searching for the smoke we found the unit smoking under the sink. We unplugged the unit, shut the water source, cut the water lines and removed the unit outdoors. We put out the fire with the water hose. The unit got so hot it caught the insulation on fire that surrounds the unit. I called the Insinkerator customer help line, they never had a report of the happening and would not assist on replacing the unit or wanting the unit back. Very scary event for us and we were glad we were home to deal with the fire.

The product, in the report: Emerson Insinkerator Hot Water Dispenser

Text of Report submitted:
Report Date: February 28, 2013 Our File Number: [REDACTED] To: Superior Adjustment Bureau Attention: [REDACTED] Carrier: Auto Owners-Clarkston Claim Number: [REDACTED]Insured: [REDACTED] Location of Loss: [REDACTED] Date of Loss: January 6, 2013 Type of loss: Fire Date Received: January 16, 2013 Date of Site Inspection: January 18, 2013 Date of non-destructive lab exam: January 21, 2013 Date of destructive lab exam: February 27, 2013
On January 18, 2013 our Company visited the loss site to collect artifacts related to the loss and examine the area of origin. During this site exam the insured provided us with (1) Emerson Insinkerator Hot Water Dispenser which had been removed from beneath the kitchen sink. According to the insured, the Manufacturer advised her to send the appliance back to the Manufacturer for inspection and requested that she not make an insurance claim. This appliance was packaged to be shipped when we received it.
As we examined the area of origin we found the base cabinet damaged as a result of water leaking from the area around the Dispenser. The Insured indicated that she smelled something burning and discovered the Insta-hot appliance smoking and leaking into the base cabinet. At that time the Insured disabled the appliance.
While examining the receptacle which supplied power to the Insta-hot, we did not find any signs of fire origin. In addition, we did not find any sign of electrical activity that could have contributed to the failure of this appliance.
This appliance was taken back to our Farmington Hills Facility for a non-destructive lab exam. During this lab exam we found evidence of water leaking at a factory fitting. As a result water had collected at the bottom of the appliance and the metal enclosure had begun to oxidize/rust.
As we researched known problems with Hot Water Dispensers, which included several recalls, we found a recall which is very similar to the problems we see with this Dispenser. The recall is for a dispenser which is several years older however the design is the same.
The recall we found involves a hot water dispenser that had a fire causing extensive damage to a kitchen. The appliance had a leak which went undetected by the home owner. This leak was not discovered until it began to smoke due to an electrical short that had developed. The bottom of the dispenser was rusted due to this leak. As a result of this leak the insulation became soaked, exposing electrical components to a constant source of moisture. Electrical activity caused by the moisture created an ignition source for plastic components within the dispenser.
In light of this earlier recall and the similarity to this loss, we feel very strongly that this recall should have been extended to include newer Hot Water Dispensers that share the same design.
Upon completion of the non destructive lab exam we made contact with Emerson (Manufacturer) to arrange a destructive lab exam at our facility. This exam was set for February 27, 2013.
During the destructive lab exam [REDACTED] was present to represent Emerson. During this exam we broke down the dispenser to expose the internal components. In doing so we found evidence of water leaking in several locations, specifically the top of the unit where signs of water were found traveling down to the electrical components of the heater assembly.
These internal leaks appear to have been occurring over a period of time causing internal electrical components to corrode. These leaks also appeared to contribute to the rust developing on the outer shell of the dispenser. Upon disassembly it became apparent that this rust had developed from an internal leak as the bottom portion of the Dispenser was rusted from the inside.
When we removed the cover of the Dispenser we found the plastic dead front melted to the control and we found the electrical connections badly corroded. Evidence of localized heating at this point identifies that a high resistance connection was causing electrical activity to occur which raised temperatures capable of igniting the plastic cover.
Further inspection of this area showed that the wires to the Heater Assembly and Thermostat showed signs of electrical activity and thermal damage.
Deteriorated electrical connections and terminals were identified as the source of ignition and the plastic cover provided a solid fuel.
The balance of this investigation was focused on determining the source of the leak and/or leaks which contributed to the breakdown of the electrical components.
We examined the John Guess Fitting, a quick connector that is factory mounted to the top of the water tank and supplies the Head Assembly with hot water upon demand. We first removed and examined the clear plastic water hose that leaves the tank and supplies the Head Assembly. It was undamaged and appears to have been inserted properly, being pushed all of the way into the fitting, eliminating installer error.
As we removed the Collet, the O-ring crumbled and broke apart, no longer pliable as it once was. To further test the tank we began to fill the tank with water and additional leaks emerged from the connections where the heater penetrates the tank, as if prolonged heat deteriorated the seals. These leaks would have been worst if under pressure and/or exposed to radiant heat from normal usage.
Testing of the heater element showed the elements at 19 ohms of resistance. A continuity test of the thermostat showed the thermostat was closed at the time of testing. The significance of these tests shows that the thermostat is operational and that the heater element is intact. With the heater element intact it shows that the heater did not fail catastrophically and contribute to the cause of this fire.
Upon completion of this lab exam we identified that a leak or several leaks contributed to the electrical components being exposed to an environment in which they are not rated for. As a result, oxidation caused high resistance connections along with electrical activity which raised temperatures in areas where exposed combustibles could breakdown and ignite.
At this time our investigation is complete. The artifacts removed from the loss site will remain in our evidence room until otherwise instructed. Evidence will be billed for a period of 6 months. Written notice by an Auto Owners Representative will be necessary for disposal of evidence.
If we can be of any further assistance, please advise.

(5/29/2013) InSinkErator: CPSC Report ID 20130416-FF5F4-1321144
The purpose of this response is to reply to the April 16, 2013 submittal to the CPSC of the above-referenced consumer complaint.
This product is designed and manufactured in compliance with all recognized national standards applicable to hot water dispensers such as the Model GN-3S-5 referenced in this report. Hot water dispensers of this type incorporate non-pressurized vessels that fill with water only when the faucet handle is activated. And while this model is similar in appearance to the units affected by InSinkErator’s 2002 “recall to repair” program, the subject model does not include the insulating material that was the focus of that program.
InSinkErator first began production of this particular model in 1998; however, the specific date of manufacture for the subject hot water dispenser is presently unknown. The hot water dispenser involved in this incident incorporated a replacement water tank that was manufactured and installed in December 2005. The circumstances surrounding the replacement of the tank are not presently known to InSinkErator. The replacement tank was approximately 7 years old at the time of the incident described in this report.
InSinkErator first received notice of this incident from the consumers on January 14, 2013, and had multiple direct communications with the consumers after that date to address their concerns. InSinkErator did not have an opportunity to examine the hot water dispenser in place prior to removal by investigators believed to be working on behalf of the property owners’ insurance carrier. A representative of InSinkErator attended a destructive examination of the unit on February 27, 2013. The report prepared by the investigators following the destructive examination is set forth verbatim in the incident description.
Based on a visual inspection of the unit during the February 27, 2013 examination, it appears that the hot water dispenser had not been properly maintained prior to the incident. During the examination, InSinkErator’s representative observed significant evidence of prior water leakage on the external surfaces of the unit, including substantial rusting on the jacket and along the edges of the base. The paint was puckered and blistered around all four sides of the lower portion of the jacket, and the base of the unit was coated in scale and mineral deposits. When the hot water dispenser was removed from the cabinet following the incident, the insurance adjuster documented evidence of water damage on the wall behind where the dispenser had been installed and along the base of the cabinet directly below the dispenser. The source of the water leak was found to be a degraded O-ring on the inlet water fitting; leakage would occur at this fitting any time the faucet handle was actuated. Given the poor condition of the unit when first produced for InSinkErator’s examination, it appears the hot water dispenser had been leaking for an extended period of time prior to the incident and had been left in service without repair.
Upon removal of the jacket and the expanded polystyrene foam that serves as an insulator between the tank and the steel jacket, it was possible to observe that the water leakage had also damaged the phenolic thermostat used to regulate water temperature inside the tank. The sustained presence of water corroded the electrical connections over time, leading to localized high-resistance heating on the control and melting of the personnel protector. The melted plastic produced an acrid odor and left soot deposits inside the cabinet where the hot water dispenser was located. Any damage to the thermostat was contained inside the unit and there was no evidence of electrical arcing that penetrated the steel jacket.
At no time did InSinkErator request that the consumers not submit a claim to their property insurer. After first contacting InSinkErator, the consumers were uncertain about how to proceed and communicated with InSinkErator on several occasions about whether to involve their insurer given the deductible and the potential for increased premiums. The consumers ultimately elected to submit their claim directly to InSinkErator and this claim was resolved in April 2013.

The product, in the report: Tank installed in kitchen cabinet under sink to provide instant boiling water and cold filtered water through specific-to-the-product faucet.

We had an Insinkerator InstaHot installed with our kitchen remodel in Feb., 2005. I loved using the product so much, that we replaced the tank for $ 189.00 in May, 2008, since it was no longer heating. In Nov., 2009 we replaced the faucet, which was continually running, for $153.00. On Jan.18, 2013, I smelled a hot, electrical, burning smell in the kitchen. Upon checking several possibilities, I discovered that the InstaHot faucet was leaking hot water into the sink. The tank unit was smoking inside the cabinet. The cord was laying in water that had leaked from the unit so my husband immediately unplugged it. This happened on a Friday evening and luckily we were home, although we had almost gone out for the evening. The whole house could have gone up in flames !!! Although I loved using the product ( when it worked correctly), we will NEVER buy another one. My husband is a kitchen designer and will no longer be recommending this product.

The product, in the report: Instant Hot Water Dispenser Model SST, tank/heater unit mounts under sink with faucet mounted in sink. Provides instant 200 degree hot water. All models use same tank with different faucet designs.

Insinkerator hot water dispenser started leaking water under sink. Upon removal and disasasembly to see why it was leaking, discovered that a plastic water line from the tank to the top reservoir is routed on top of the tank half lip and surrounded by [REDACTED] insulation. The plastic water line melted from the heat of the metal tank lip and scorched the [REDACTED] but the melted line caused the water to leak and apparently prevented further fire damage. The water went all over the interior of the unit including the power connection & temperature setting thermostate and could result in a shock or short hazard. Upon contact with Insinkerator, they advised there were no safety recalls on the unit and claimed no design defects reported but that the plastic line has been replaced by a different material since my unit was made and the tank unit is essentially the same as my unit for all models. They did offer to send me a new unit and requested that I send mine back-all w/o any warranty period discussion. I believe there may still be a design defect in this product regardless of replacing the water line with a heat proof type and consumers should be aware and product be redesigned.

The purpose of this response is to reply to the January 20, 2012 submittal to the CPSC of the above-referenced consumer complaint.
Subject unit was in service for more than 7 years. A risk of fire at the outlet and/or danger of electrical shock potentially presented by the circumstances of this incident do not exist provided the product is properly installed. Correct installation of this hot water dispenser requires the use of a grounded electrical connection, which will protect against such events. Further, this ISE hot water dispenser is constructed in compliance with UL Standard ANSI/UL 499 covering Electrical Heating Appliances.

The product, in the report: Under sink instant hot water dispenser

I have a “IN SINK ERATOR Instant Hot Water Dispenser”. Recently I noticed water under my sink and investigated to find the hot water dispenser was the culprit. Water is leaking from the point where the electrical cord enters the tank. It then proceeds to drip down the cord. Luckily, my cord must make a 90 turn before it is routed to the electrical outlet which makes the water fall on the cabinet bottom, otherwise it would enter the outlet and start a fire. This is a safety situation and the product should be recalled. I can submit photos if necessary.

The product, in the report: In-Sink-Erator Counter Top Hot Water Dispenser

In-Sink-Erator Counter Top Hot Water Dispenser Model SST Manufacture Date: Jan. 2007 Serial #: 07068725313 Tank leaked causing water damage and possible shock hazard. Water leaked into heat control electronics (110 volts) and spilled into kitchen cabinet causing wood damage.
Disassembly of major tank revealed an overheated, degraded and fractured hose leading from over flow tube to internal overflow tank. This hose is mounted against tank and obviously, the hose material is not adequate to withstand temperatures of the environment in which it operates (tank temperatures.)
There was a previous recall for similar problem. Refer to http://www.cpsc.gov/cpscpub/prerel/prhtml02/02189.html Previous recall is for previous models manufactured 1972 thru Dec. 1996. This incident is for a later model but hazard is the same.

(11/17/2011) InSinkErator: CPSC Report ID 20111025-4C256-2147473965
The purpose of this response is to reply to the October 25, 2011 submittal to the CPSC of the above-referenced consumer complaint .
Subject unit was likely in use for over 4 years. The InSinkErator Division of Emerson Electric Co. (“lSE”) has not had an opportunity to examine the unit that is the subject of this report nor seen any documentation of the installation. There is no danger of electrical shock presented by the circumstances of this incident provided the product is properly installed. Correct installation of this hot water dispenser requires the use of a grounded electrical connection, which will protect against electrical shock in situations such as this. Further, this ISE hot water dispenser is constructed in compliance with UL Standard ANSI/UL 499 covering Electrical Heating Appliances.
The fractured hose has undergone chemical degradation, not thermal degradation as suggested.
Previous recall referenced by consumer is a recall to rework, not a product recall, covering hot water dispensers of a different design produced between 1972 and the end of 1996.
