Important Tips for Samsung Models

  • Samsung support recommends simple steps like resetting circuit breaker and checking power button as initial troubleshooting.

Possible Causes

Door not fully closed or latched

How to Identify: Dishwasher won’t start but lights/power might be on; door may seem closed but not clicked in; pressing and listening for click of latch can verify.

Part: Door latch / door switch

Power supply issue (breaker, plug, GFCI)

How to Identify: Dishwasher has no lights or control response; breaker tripped; GFCI tripped; unplugging/replugging resets.

Part: Power supply / breaker / outlet

Control panel or button failure

How to Identify: Pressing buttons yields no response; touch controls unresponsive; cleaning improves response.

Part: Control panel / touch pad

Thermal fuse blown

How to Identify: Dishwasher has power but does not start; component test shows open circuit on fuse.

Part: Thermal fuse

Wire harness or internal wiring fault

How to Identify: Intermittent or no start even with correct power and door latch; visual damage or continuity test fails.

Part: Internal wire harness

Control board failure

How to Identify: No response to inputs; other causes eliminated; professional diagnosis shows board fault.

Part: Main control board
