What the iF1 Error Means
The iF1 error code indicates a fault with the water level system. It is closely related to the iF0 error code and may be caused by an overfill condition, a faulty sensor or a problem with the inlet valve allowing too much water into the appliance.
Common Reasons This Error Appears
Faulty water inlet valve
The inlet valve may be stuck open, allowing too much water to enter the appliance.
Faulty water level sensor
The sensor that monitors the water level may have failed and is sending incorrect readings.
Blocked filter or sump
A blocked filter can cause water to back up and affect water level readings.
Appliance not earthed correctly
The iF1 error can sometimes be triggered if the dishwasher is not connected to a properly earthed socket. Make sure the appliance is plugged into an earthed socket, identifiable by the metal pins at the top and bottom.
Wiring fault
Wiring connected to the water level sensor or control module may be loose or damaged.
Electronic control board fault
The control board may not be reading the water level sensor correctly.
Safe Checks You Can Try
Check the earthing
Make sure the dishwasher is plugged into a properly earthed socket. Earthed sockets can be identified by the metal pins at the top and bottom of the socket.
Clean the filter
Remove and clean the filter at the bottom of the dishwasher thoroughly under running water.
Check the inlet valve
Turn off the water supply and check whether water continues to enter the appliance. If it does, the inlet valve may be faulty.
Restart the dishwasher
Turn the appliance off and disconnect it from the mains for several minutes before restarting.
