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

Safety first: Turn off power at the breaker before inspection.

• Check power cord and plug: Ensure the Sharp dishwasher plug is fully inserted and the cord is not damaged.
• Inspect terminal block: If hard-wired, check the terminal block for loose or burnt connections.
• Check door switch: If the machine stops when the door is touched, the door switch may be intermittent and should be replaced.
• Control board ventilation: Ensure the control area is not blocked by insulation or debris causing overheating. If the board shows signs of heat damage, it may need replacement.
