Whirlpool WP661566 Genuine OEM Dishwasher High Limit Thermostat

The Dishwasher High Limit Thermostat is a safety device located at the bottom of the dishwasher. The only difference between the high-limit thermostat and the operating thermostat is their opening and closing temperatures. If your dishwasher won’t heat, replacing this part may alleviate the issue. Replacing this part will require basic hand tools such as a multi-screwdriver, some disassembly of the appliance, and novice repair experience. Before installing this high-quality replacement part, remember to unplug the dishwasher or shut off the house circuit breaker to ensure safety. Also, make sure to turn off the water supply under the sink. Helpful Tip: We recommend using affresh® Dishwasher Cleaner (item W10282479) once a month or as needed to help remove limescale and mineral buildup that can affect your dishwasher's performance. *affresh® brand products are owned and distributed by Whirlpool Corporation.
