Washing machine

E18 / F18

Drain hose or pump blocked.

Safe to check yourself · checked against manufacturer source

1. Switch off and unplug. Place towels and a shallow tray down - there may be a lot of water.
2. Empty and clean the pump filter (front kick-plate on washers, base filter on dishwashers) and remove any coins, grit or debris.
3. Check the drain hose isn't kinked, crushed or pushed too far into the standpipe, and that a new sink waste spigot has had its blanking disc removed.
4. If the pump hums but won't clear, or doesn't run at all, the pump needs replacing by an engineer.

E17 / F17

Water coming in too slowly - tap, filters or pressure.

Safe to check yourself · checked against manufacturer source

1. Make sure the tap/stopcock feeding the appliance is fully open and the water supply is on in the house.
2. Turn the tap off, unscrew the inlet hose and clean the small mesh filter at the valve end.
3. Straighten any kinked hose and check it isn't frozen (outbuildings in winter).

Door not locked properly.

Safe to check yourself · checked against manufacturer source

1. Close the door firmly - make sure no laundry or seal is trapped in it.

1. Unplug for a few minutes and restart with a smaller load.
2. Check the drum turns freely by hand (power off).
3. Repeated faults need an engineer to check the motor, brushes, tacho and drive board.

ERR8

Water level too high.

Safe to check yourself · confirm in your model's manual

1. Make sure the tap/stopcock feeding the appliance is fully open and the water supply is on in the house.
2. Turn the tap off, unscrew the inlet hose and clean the small mesh filter at the valve end.
3. Straighten any kinked hose and check it isn't frozen (outbuildings in winter).

UNB

Load unbalanced.

Safe to check yourself · confirm in your model's manual

1. Redistribute the load - a single heavy item (towel, mat, duvet) often causes this. Add a couple of similar items to balance it.
2. Check the appliance is level and all feet are locked.
3. Make sure transit bolts have been removed on a newly installed machine.
