went to this one yesterday.door locked and nothing from there on.checked brushes and they completely worn out.ran a rinse program before i left and everything ok.cust now tells me that m/c takes about 20 min to begin after after pressing start(door locks straight away).also he says it is not heating now.brushes replaced by tilting m/c back so no removal of motor or connections.comm cleaned with comm stick.will obviously check heater on return.any ideas
