Maytag Dishwasher: not heating
What is this symptom?
Is your Maytag dishwasher not heating? If the water inside remains cold or lukewarm during or after the wash cycle, it can lead to poorly cleaned dishes. The internal heater may be malfunctioning, causing ineffective sanitation. This issue can stem from various causes, including a faulty heating element or incorrect incoming water temperature.
Important Tips for Maytag Models
- Maytag emphasizes ensuring proper incoming water temperature for effective wash performance, which impacts internal heating performance.
Possible Causes
Faulty Heating Element
How to Identify: Water remains cold, no steam at end of cycle, visible damage or break in the heating coil; continuity test with multimeter fails.
Part: Heating Element
Malfunctioning Thermostat / Temperature Sensor
How to Identify: Dishwasher never triggers heating even when water is cold; multimeter tests show incorrect or no change in resistance.
Part: Thermostat / Temperature Sensor
Incorrect Incoming Water Temperature / Supply Issue
How to Identify: Dishwasher not connected to hot water supply or household water heater set too low; incoming line supplies cold water.
Part: Hot Water Supply Line
Control Board or Timer Fault
How to Identify: Dishwasher cycles behave erratically, skip heating phases, or show error codes; visible damage on board.
Part: Control Board/Timer
Clogged Filters or Blocked Spray Arms Affecting Heating Efficiency
How to Identify: Poor water circulation and distribution with cold spots, dirty dishes despite heating attempts.
Part: Filters / Spray Arms
DIY Solutions
Check and Clean Hot Water Supply
- Verify the dishwasher is connected to the household hot water line under the sink.
- Run hot water at the kitchen sink to ensure the heater is delivering at least ~120°F to dishwasher.
- Adjust household water heater if needed.
Inspect and Test Heating Element
- Disconnect power at breaker.
- Remove lower access panel and locate heating element.
- Visually inspect for breaks and test for continuity with multimeter.
- Replace the element if it shows no continuity.
Clean Filters and Spray Arms
- Remove bottom rack and take out filters.
- Rinse filters under warm water and brush away debris.
- Detach and clear spray arm nozzles of blockage.
- Reinstall and test dishwasher.
