Dishwasher stops mid-cycle and shuts off completely without displaying an error.

Safety first: Disconnect power before inspecting electrical components.

• Check power connections: Inspect the junction box or power cord connection for loose wires or signs of arcing. Tighten and repair as needed.
• Door latch and switch: If the machine stops when the door is touched or moved, the door switch may be intermittent. Replace the door lock assembly.
• Control board ventilation: Ensure the control area is not blocked and that there is no sign of overheating or burning on the board. Replace if components appear heat-damaged.
• Thermal fuse: Some models include a thermal fuse on the control board or wiring harness. Test continuity; if it opens intermittently, replace it and investigate the cause of overheating.

Intermittent faults can be difficult to trace; if the issue persists, professional diagnosis is recommended.
