Why is my dishwasher not heating the water?
If your dishwasher runs but the water stays cold, the most common causes include a faulty heating element, a malfunctioning high-limit thermostat, or a defective control board. Modern dishwashers rely on properly heated water to break down grease and sanitize dishes.
Cold water during the wash cycle often leads to cloudy glasses, greasy residue, and longer cycle times.
If you’re unsure about the cause, our professional appliance repair services can diagnose the issue quickly and safely.
