Can you tell me the full model number from the label behind the door please
It refers to the fact that you have water in the base of the appliance.
Tilt the appliance backwards until the water in the base is expelled, then try another wash. If the water ingress occurs again you'll need to investigate for sources of the leak
Try unplug the appliance from the wall for 10 minutes to discharge the electronics, then try a wash again.
If the machine is under the worksurface and you can't pull it out how did you tip it back?
You need to actually pull the washer out and tip it back to 45° to expel the water.
I notice you have given me a negative rating of one star. I would appreciate it if you rated three stars or more. The answer is correct, it is not my fault that you have not pulled the washer out to tilt it backwards as instructed.
