The above washer overfills with water up to about 3/4 full in the drum. It then empties down to about half and then refills back up to 3/4. I have checked all pipes for any blockages but as the pump empties this is not a problem.I have replaced the pressure switch without success. Even on a Pump and spin cycle water enters the drum. As the inlet valves switch off when I disconnect from the mains this is not a problem. The outlet hose is in the same position as when it operated O K for over 2 Years. Any ideas please ?
