from what i can see quickly Fault 4 is a flood fault so the base of the machine must be still flooded and needs to be dried out
tilt machine back slowly. you need to do it slowly so the water, if its there, does not get on the electrics. if water comes out then it should then work
Thanks again for your response. I looked further on-line and found a suggestion to leave the door open for a time, machine unplugged. I did this overnight (in pure hope) over the weekend and the machine reset itself. I’ve just done a test wash and all is OK. This has saved me getting a plumber and having to strip out the kitchen unit to access the machine.
