I have a fault on this which in a full sized dishwasher I would automatically change the impellor jug. I still think that will be the problem, but the flow meter looks to be part of the metering tank. It pumps out and fills as normal, then shows E14 after about a minute. I have checked the inlet valve and water pressure, and all is ok. Any ideas please? Or conformation of my theory would be helpful. Cheers. Steve.
