Then empties and then keeps refilling until it floods the sump. I dried it all out and tried again. same thing only I turned machine off after about 50mins as water had reached the door seal. I turned off machine and pumped it out, only then did the machine beep and shut down. Prior to this the machine filled and stood idle, so I disconnected the flow switch and blew through and the wash began. all good until the above began. Could it be a faulty flow switch something else?
