Dishwasher overfills with water, with water reaching the door opening or triggering the anti-flood system.

Safety first: Immediately switch off power and close the water tap if overfilling occurs.

• Check inlet valve: If water continues to enter with the power off, the inlet valve is mechanically stuck open and must be replaced.
• Inspect pressure hose: Ensure the small hose from the sump to the pressure switch is connected and not blocked.
• Test pressure switch: Verify that the switch changes state when pressure is applied. Replace if faulty.
• Check control board: If the valve only overfills when powered, the control board may be driving it incorrectly and may require replacement.
