Thermostats regulate the water temperature of your dishwasher and prevent the heating element overheating the water by maintaining a constant water temperature range. A faulty thermostat can result in your dishwasher’s water not reaching optimum temperature or failing to heat the water at all. Over time, components wear or can become damaged through lack of care or misuse, Norris supplies a range of replacement thermostats, temperature gauges, controllers and cut-out switches to keep your dishwasher functioning as the manufacturer intended.
