Re: A Diplomat ADP 8252 that just won’t go!
In which case the temperature sensing circuit probably is at fault, switching it on and off won’t clear the problem until the faulty component has been identified and replaced/repaired, I guess it ‘s just a suggrestion to try that in case of software “lockout”.
It may be one of the thermostats, heater or the PCB itself, and possibly even the dispenser which can throw up some odd faults at times.
Best bet is ask an engineer to check it for you, try repairs@ and the directories.
Please don’t “axe” it yet 😀
