Re: Diplomat D/washer tripping stat
Couple of possibilities.
It could be the one where the ‘official’ fix was to pull the heater apart slightly where it covers the stat. Originally it was too close and caused the stat to o/heat. (The newer ones are a different shape around the stat now).
Alternatively it could be the usual 3 in1 tablet issue combined with customer still putting R/aid and causing machine to oversud and therefore overheat the stat.
