I had a look at one of theses this morning. It’s filling, washing for about 6 minutes, then pumping out. It done this 3 times while I was there. I’m waiting for the customer to call me to see if it continued to do this. Any ideas?
NTC could be faulty or heater faulty. Had one done this when connected to hot water supply instead of cold. Look to see what last error was & report back.
