Possible Causes

Faulty relay on main control board, Software glitch, Overheated control board, Loose harness to key components

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing the control board compartment.

Step-by-step checks:

  • Power cycle: Turn off the breaker for 10 minutes to reset the control.
  • Ventilation: Ensure the area around the dishwasher is not excessively hot and that the toe-kick is not blocked, which can overheat electronics.
  • Inspect control board: Remove the toe-kick and any access covers to reach the main board. Look for burn marks, swollen components, or a burnt smell.
  • Harness check: Verify all connectors are fully seated and locked.
  • Replacement: If visual damage is present or E19 persists, the main control board typically must be replaced.

Warning: Do not attempt to repair the control board at component level unless you are qualified; replacement is the safe option.
