Dishwasher shows no response when any button is pressed; display is blank or completely unresponsive — main control board has lost power regulation.
Dishwasher continues to run indefinitely and cannot be stopped; control board fails to signal cycle completion or halt motor circuits.
Unit starts normally but halts partway through a cycle, sometimes with random indicator lights flashing, indicating the PCB is failing mid-operation.
Dishwasher drains right at cycle start, then cuts out before washing begins — a classic symptom of main PCB logic failure.
Persistent fault codes related to flooding, water level, or cycle errors that do not resolve after checking sensors and wiring point to a failed main control board.
💡 Pro Tip: Is Your Main Control Board Really the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher won't turn on or turn off — no response to any button press
⚠️ Cycle stops mid-way with no error code or with random flashing lights
⚠️ Dishwasher starts then immediately drains and halts without washing
⚠️ No 5VDC output detected between CN301 pin 5 and CN302 pin 4 during diagnostics
🔍 Before replacing the board, rule out the turbidity sensor (DD32-00003A) and the case break/overflow sensor assembly (DD82-01373A). Use a multimeter to confirm 5VDC at CN301 pin 5 → CN302 pin 4. Zero voltage = failed main control board. If voltage is present, the fault lies downstream.
