Hi. Went to one of these today. If you put it on the spin and pump out prog the pump comes on for a few seconds and then it clicks and no drum action. Tried it on several washes too no drum action. Machine about 16 months old but had a look at the m/brushes and motor t/coil/ and magnet-fine, armature looks ok too and thermal fuse- everything reads something motor tag to tag. Had a look at main pcb in fascia, looks fine too. Anyone got any pointers please and lastly has anyone got any idea what the small dc board actually does?
