Sometimes it trips out at the start of the rinse cycle, sometimes it carries on for a bit longer. On the odd occasion it has completed a full wash without tripping. It drains ok.
Up to now neither I nor espares can identify this main control board. Can you give me an idea where it is located?
There is only one button on this model and that is the on/off switch located on the right hand side of the facia panel. Programme selection is by a knob on the left hand side of the facia panel. The only light is a neon one located above the on/off button. Is the main board there?
Thanks for your help. This dishwasher has performed faultlessly for 23 years which must be something of a record. I've checked availability of a new timer and think it uneconomic to preceed with repairs. It's time for a new dishwasher.
