User Suggested Solutions

  1. Test and replace the heating element. First, disconnect the dishwasher from power. Access the heating element by removing the bottom spray arm and the cover. Use a multimeter to test for continuity. If faulty, replace it with a new one.

  2. Check and replace the thermostat. Disconnect power, locate the thermostat (usually near the heating element), and test it with a multimeter. If it shows no continuity, replace it.

  3. Inspect the control board for damage. If the heating element and thermostat are functional, the issue may lie in the control board. Look for burnt components or loose connections. If damaged, replace the control board.
