I have a 18month old Beko ProSmart inverter DFN26220X dishwasher, it recently stopped fuctioning and displayed E01 on the display. information i found suggested it had overflowed and was trying to constantly pump out the water. i disconnected the machine and found water in the lower tray, dried this out and reinstalled the machine. It then continued to fill to a point of overflowing whilst showing error 02. the unit was sent to an official Beko repair center (here in Bulgaria) and was returned 3 weeks later as no problems or errors found. i reinstalled the unit and it worked fine for 1 week. it is now showing error 01 again and constantly trying to pump out water allthough nothing is exiting the drain pipe. after removing and re attaching the power supply the machine pump just starts again with error 01 showing .. Any advice, help, suggestions please
