I have a Diplomat ADP 8132 which is about 10 years old, and no trouble to date. It has just recently started tripping out my RCD during the wash cycle, which I then reset, and trips again after a minute or so. However, when I put it in to rinse cycle to empty it, it ran no problem. I am guessing that it is the heating element breaking down and causing some earth leakage? If I am correct, is this a reasonably easy job to do myself, and any hints, tips – thanks.
Re: Diplomat ADP 8132 tripping RCD
Heater-as good a guess from you end as it is from mine. Presume you have the element visible from inside the tank- a dog legged looking element and not an element tube that is under the tank out of sight. If the dog legged jobby then yes it is easy to replace but before you buy it have a good look at the element for any obvious burn marks, splits, or just looks `bad`. To test it. power off/unplug, remove the wires off the element, you`ll need a multimeter set on 1k ohms, test each terminal of the element to earth-if you get any reading it is duff. Also test terminal to terminal if you get no reading the element is also duff. Make sure that when/if replacing the element you tighten up the rubber/boss nut/s up without over doing it and make sure if there was an earth wire/s you refit them.
Re: Diplomat ADP 8132 tripping RCD
Just a quick update. Got the new heater element and installed it, runs as good as new now, so pleased it was just that. Quick note on installation. It is fairly easy to get at from the front once the lower cover is removed, although a bit fiddly. You will need an 8mm box spanner or similar to get the fixing nut off – it is a long thread, I had to knock 2 sockets together to get at it. The 2 wires just pull off, just remember which goes where, and the earth is on a separate plate that comes off once the fixing nut is loose. The element just lifts off from inside the washer unit. Took me about 30 mins to do the job. There was no visible corrosion on the old element, just some discolouring that did not look too bad, but was obviously enough to get some earth leakage.
