I have D61D dishwasher. As it neared the end of programme the electrics tripped. Next day swiched dishwasher on and it was making whirring noise and dial wouldn't move, only manually. No water entering machine. Put water in the machine manually and it pumped it out okay. Bright idea courtesay of my other half was to leave machine running. Did that and guess what? The trip switch for the electrics went again and now nothing. Any ideas please?
