Dishwasher stops mid-cycle and all lights turn off, then may restart later.

Safety first: Disconnect power before inspecting wiring or controls.

• 1. Inspect terminal block: Check that all wires at the power connection are tight and not discolored or burned.
• 2. Check door switch: Wiggle the door gently during operation; if the machine stops, the door switch or latch is likely faulty.
• 3. Control board ventilation: Ensure the control area is not blocked and that insulation is correctly placed to avoid overheating.
• 4. Thermal devices: Some models have thermal cut-outs on the control board or heater. If they trip, identify and correct the cause before resetting or replacing.
• 5. Replace faulty components: Replace the door lock assembly or main control board if they are confirmed to be the source of intermittent power loss.

Warning: Intermittent electrical faults can pose a fire risk; address promptly.
