Part: Heating element (heating coil)

Faulty thermostat or temperature sensor

How to Identify: Dishwasher not heating despite element continuity; thermostat fails continuity testing; temperatures not regulated correctly.

Part: Thermostat/NTC temperature sensor

Electrical connection issues (wiring/relay)

How to Identify: Intermittent heating, error codes persist after reset; visual signs of burnt or loose wires; control board relay faults.

Part: Wiring harness, control board relay

Limescale/mineral buildup

How to Identify: White scaling on element, reduced heating efficiency over time; especially in hard water areas.

Part: Heating element surface

DIY Solutions

Test Heating Element for Continuity

Moderate 30–60 minutes
Tools Needed: multimeter, screwdriver
  1. Turn off power to dishwasher.
  2. Remove lower rack and access heating element terminals.
  3. Disconnect wires and use multimeter to measure resistance.
  4. If no continuity, heating element is faulty and needs replacement.
⚠️ Safety First: Always disconnect power before testing electrical components.

Descale Dishwasher to Reduce Mineral Buildup

Easy 60 minutes
Tools Needed: descaling solution or vinegar
  1. Remove dishes and run an empty cycle with descaling solution.
  2. Ensure solution contacts bottom area around heating element.
  3. Rinse with a normal wash cycle after descaling.
  4. Repeat periodically based on water hardness.
⚠️ Safety First: Use descaling products as directed; avoid contact with skin/eyes.
