Is This the Right Part?

Common Symptoms

• Poor cleaning results
• Abnormally long or short cycle operation
• Heating or drying-related problems when the sensor provides inaccurate readings

Check Before Replacing

• Inspect the sensor area for visible mineral buildup, corrosion, cracking, or damage after disconnecting dishwasher power.
• Verify the dishwasher model number against the manufacturer's parts lookup before ordering.
• If the dishwasher has cleaning, cycle-length, or heating symptoms, test the sensor and related wiring according to the appliance service documentation; symptoms alone do not confirm sensor failure.
