Dishwasher overfills or water level too high in tank, may leak from door and E2 is displayed.

Safety first: Disconnect power and close the water supply. Mop up any spilled water to avoid slipping.

• Inspect tank for overfill: Open the door and check if water level is above the normal operating level (usually just below the tank overflow).
• Clean pressure system: Remove side or front panels (depending on Maidaid model) to access the pressure chamber and thin pressure hose. Detach the hose from the pressure switch and blow through it to clear blockages. Rinse the chamber if accessible.
• Check inlet valve operation: With power off, inspect the Maidaid inlet valve for signs of debris or scale preventing it from closing. If the valve continues to pass water when de-energised, it must be replaced.
• Test pressure switch: Using a multimeter, check continuity on the Maidaid pressure switch while gently blowing into the pressure port. The contacts should change state. If not, replace the switch/level sensor.
• If overfill persists: The control PCB may be energising the valve incorrectly. This requires a qualified Maidaid technician to diagnose and replace the control board.
