I would guess the pump motor is an Askoll magnetic type. This has tendency to twist and put a strain on the short concertina outlet hose. This hose splits, and voila, base full of water, shorts out motor terminals. New motor part number 481236158432 is CESET capacitor start type, retails approx £100. Check new motor turns before fitting as I have found poor assembly can jam rotor. Also I have previously found control module blown due to shorting of motor, but after resoldering tracks on module all worked ok.
Hope this helps
