Re: Diplomat ADP 8242 program stop
This is a SMEG-built appliance. They are recent quality machines, but subject to quirky faults. The problem you have points to some sort of logic problem with the computer board – however, this can be affected by a number of external facors. A read of THIS article may help.
You might like to consider pro help on this one – as a private individual, you have little choice but to throw parts at it until it works – an expensive choice.
Power off if you intend to investigate this yourself.
