Samsung dishwasher won’t start
Samsung no-start troubleshooting checks power, the door latch, control settings, and an approved reset before service.
What this guide covers
Symptoms: Dishwasher will not start / operate
This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

Safe troubleshooting sequence
Start with the observations and external checks that can be verified without opening energized assemblies. The interactive version asks these in order and changes the path based on your answers.
- Check household powerThe dishwasher needs normal power before any control troubleshooting.
- Confirm the door is latchedA door that is not fully closed prevents a wash cycle from starting.
- Check Control Lock, Delay Start, and Start/ResumeA locked control or delayed cycle can look like a no-start condition.
- Try the manufacturer reset only after the basic checksA brief power reset can clear a stalled control state.

A one-time stalled state was cleared by the approved reset.
Evidence strength: Strong
The safe no-start checks are exhausted
Persistent no-start behavior after power, door, controls, and reset checks needs model-specific diagnosis.
Evidence strength: Strong
When professional diagnosis is the safer next step
Persistent no-start behavior after power, door, controls, and reset checks needs model-specific diagnosis.
Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
