I believe that it is as it took the ELCB out but how can I check for sure before I order a new one? I assume by a resistance measurement? Should the normal working resistance be [(230×230) / nominal power rating]? April 29, 2010 at 11:09 pm #319061 Penguin45Participant Re: Diplomat APL8225 dishwasher not heating. Power off, machine out and tipped back, drop the base tray. Split the circuit to the heater and meter it on a low ohms resistance setting. Somewhere around 25ohms is acceptable. If it is, check the wiring at the pivot point of the door. Penguin45. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
