Hotpoint utlimate 1300

Hi,
Error "E-30" means motor fault, there are 3 main causes,
1) motor brushes worn.
2) wiring between motor and module bad connection or broken, pull on the wires gently on the ends, also look under the cable ties for chaffing.
3) Power module blown, this is located at the front (above the door seal), remove lid, front console panel (careful you dont damage ribbon cable when removing) remove front module then you will see plastic clips holding the power module on, have a look at the track of the module.
