I have just replaced the bearings and spider on this machine after the bearings disintegrated and blew the machine. Now if I try a wash cycle the MCB trips but not immediately. If I try a spin cycle the drum turns a few times and the machine attempts to empty water ( there is none in there), it does this for a few minutes then gives me the error code E15 outlet blocked. If I try a drying cycle I get the E15 code immediately. I can't see any obvious faults with the electrics. The heater element appears OK Resistance of approx 27ohms. Pressure switch appears to be working, pipe to pressure switch is clear and obviously I have checked outlet pipes and they are clear. What else can I do?
