Dishwasher intermittently stops mid-cycle without any error code, then may resume later.

Safety first: Disconnect power before inspecting electrical components.

• Check mains connection: Inspect the power plug, socket, and any junction box for loose or overheated connections.
• Inspect door switch: Ensure the door latch and switch maintain firm contact. Replace if there is play or intermittent continuity.
• Overheating pump: If the machine stops after some time and restarts when cool, the circulation pump may be overheating. Check for restricted water flow and replace the pump if necessary.
• Control board: Look for signs of heat damage or cracked solder joints on the PCB. Replace if faults are found.

Intermittent faults can be difficult to trace; if unsure, consult a professional technician.
