Samsung dishwashers may appear unresponsive when the door is not latched, a cycle option is holding the start, or the control has not completed its wake-up sequence.
Safety first: Unplug the appliance before touching accessible hoses, filters, or panels. Do not bypass a door or lid switch, probe live wiring, or continue using an appliance with smoke, a burning smell, sparking, a hot plug, repeated breaker trips, or water near electrical parts.
Most Likely Causes
1. Child Lock or Delay Start is active
Check panel indicators before pressing buttons repeatedly.
2. The door latch is not engaging fully
A rack or dish can keep the strike from meeting the latch.
3. Smart Control or a paused cycle needs a fresh Start command
Use only the Start procedure printed for the exact model.
4. The appliance has lost power
Check panel indicators before pressing buttons repeatedly.
5. The water supply is restricted
A rack or dish can keep the strike from meeting the latch.
6. The control needs service
Use only the Start procedure printed for the exact model.

Step 3: Inspect door closure

Step 4: Confirm power
Use the model’s use-and-care instructions.
Step 5: Check water valve
Do not force a latch or probe live wiring.
Step 6: Perform a five-minute reset
Run one normal cycle after restoring power.

When to Call a Professional
Book service if the safe checks do not solve the problem, a code or symptom returns, or the repair requires meter testing, internal wiring access, appliance removal, or disassembly. Stop immediately for burning odor, sparks, hot wiring, breaker trips, or water near electrical parts.
