can any one help.i have a ADP8252 dishwasher.when i opened the door i seen that the tablet had not dissoveled,on ringing up the help line they told me it was the thermo on the machine that would need replacing at a cost of £40.but knew that wasnt right because the dood got hot after a wash, when looking at the display on the door i have seen a symbol that looks like “_ l”,if i switch the on/off button on and off it goes to the programme i want then returns to the “l _” symbol then will wash,also if i leave the on/off button in the on postion and open the door then close it the machine will start up by its self and do the next programme up(from 6 to 7).am pretty sure that some soapy water got into the top of the door but carnt be certain, any help would be greatfull.
