Samsung Dishwasher: not running
What is this symptom?
Experiencing issues with your Samsung dishwasher not running? This common problem often results in a complete lack of operation when the start button is pressed. Even if the lights are on, no cycle begins, and there’s no motor noise. Understanding the potential causes can help you troubleshoot effectively.
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
