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

Safety first: Turn off power at the breaker before inspecting electrical components.

• 1. Check terminal block: Inspect the power connection box for loose or burned wires. Tighten or replace connectors.
• 2. Inspect control board: Remove the inner door panel and look for signs of overheating on the control board (burn marks, melted plastic).
• 3. Test door switch: A failing door switch can intermittently open the circuit. Test for consistent continuity when the door is latched.
• 4. Avoid overloading circuits: Ensure the dishwasher is not sharing a circuit with high-draw appliances that could cause voltage drops.

Intermittent electrical issues can be complex; if basic checks do not resolve the problem, contact a professional technician.
