Ive got a 4-5yr old Neff W5420 washing machine and its stopped working - I can select any function and press the start button, the door locks and the pump starts spinning but then the RPM, SPIN & READY neons simultaneously flash with an alternating beep, if i return the function control to OFF it will stop. The door locks normally but has to be realised on the pull wire, the drum manually spins and the seals look fine, the pump spins and the filter is clean? Any ideas? Thanks Simon
