pump is probably blocked, which is why it wont drain and keeps cycling round. Very easy to repair, 20 mins.
Switch OFF at mains.At front remove lower trim cover,unscrew plastic cap at front bottom right. have bowl ready to catch water. check and remove obstructions. try again.
also check underneath where black pipe comes into pump for blockages, Tilt washer back and use mole grips to remove clip, have bowl ready again if any water in.
