Dishwasher stops mid‑cycle and appears dead, but will work again after cooling.

Safety first: Disconnect power before inspecting ventilation or internal components.

• Improve ventilation: Ensure there is adequate space around the dishwasher, especially at the sides and top, as per Zanussi installation guidelines.
• Clean filters and spray arms: Restricted water flow can cause pump overheating; keep them clean.
• Check for obstructions: Make sure insulation or cabinet panels are not blocking vents near the control board.
• Service pump/board: If overheating persists, a technician should test the pump and thermal devices and replace as needed.
