I have a kenwood counter top dishwasher KDWTTB10. It is turning on and lighting up but not responding to any button pressing for programme. the whole panel flashes showing dishes/pans/salt/rinse aid/888 the lot! Occasionally it will display H:00 all the way through to H;25 around and around. Sometimes it counts backwards from 18 whilst it 'runs' quickly filling and emptying. Sometimes it displays 6E. It has never displayed E4 or any of the other codes. I have tried taking the front off to check wires and door closing mechanism..all fine. I have thoroughly dried out the appliance...nothing. I have pressed every combination of buttons. I have sworn. I have punched it. It has done this a couple of times before, but I ignored it and left it overnight and it turned on fine....not this time. Please help?
