Voluntary Corrective Action Information


Why is the SinkTop Switch undergoing a corrective action plan and voluntary replacement?

Safety is the top priority for Emerson and its businesses. There have been isolated incidents of overheating caused by water leaking into the Single Outlet SinkTop Switch's electrical power module, creating a short circuit hazard. Even though the product is not intended to be exposed to water, InSinkErator has elected to provide replacement SinkTop Switch kits that are better able to withstand accidental exposure to water.


How many incidents have been reported? Have these incidents caused any injuries or substantial damage?

As of the start of this safety notice, InSinkErator had received about three dozen reports of water damage causing overheating of the listed models of SinkTop Switches. All of the reported incidents have involved limited damage under the sink. No one has been injured.


What are Emerson and its InSinkErator business doing about this problem?

We have halted shipment of the product and had it removed from store shelves. We have launched a corrective action plan and voluntary replacement program to provide affected customers with a replacement SinkTop Switch kit that is better able to withstand accidental exposure to water.


What is different about the replacement switch that makes it safer?

The Dual Outlet SinkTop Switch provided with the replacement kit features upgraded seals and other improvements to protect against water causing overheating.


How does the corrective action plan and voluntary replacement program work?

With the approval of the Consumer Product Safety Commission, Emerson is asking its consumers to do the following:
• Disconnect the power module to see the label and click here to determine if your model is affected.
• If your model is affected, you will be directed to register your product for a free replacement.
• Consumers will be asked to provide the model number, date code, and their mailing address.
• Consumers will receive a free SinkTop Switch replacement kit within 7-10 business days and are instructed to discard and/or recycle their original Single Outlet SinkTop Switch.
