Dishwasher stops mid-cycle without any error code; lights may remain on.

Safety first: Disconnect from mains before inspecting electrical components.

• Check power supply: Inspect the plug, socket, and any extension leads. Avoid using extension leads for dishwashers.
• Inspect door switch: If the machine stops when the door is touched, the door lock switch may be intermittent and should be checked and replaced if necessary.
• Ventilation: Ensure there is adequate ventilation around the dishwasher and that insulation or cabinets are not blocking vents.
• Control board: If the appliance restarts after cooling, the control board or heater thermal cut-out may be tripping and should be checked by a technician.
