Malfunction is indicated by a continuos tone which can be heared, even when machine is switched off.

How do you reset?

Many, many thanks to D Graham for taking the trouble to reply here. I've saved masses of money/time or both.

Although my model was different the principle still applies. I've now carefully cleaned all of the door seals (scaling in some areas) and will drop the habit of opening the door with the machine running now that I know it can have a side effect!

I had this problem and found the plastic tray underneath the dishwasher was filling up with water which made it think there was a flood.
For may months I just used a Vacs wet hoover every couple of weeks with a 6mm plastic hose taped to the nozzle which I inserted under the bottom of the door when it is open and sucked the water out of the plastic tray.
You need a torch and have to remove the lower small white panel beneath the door.
Best to turn off the mains also.
It turned out the water was getting past the door seal I think and this was eventually sorted when the salt dispenser packed up and a service engineer replace some bits.
