Re: diplomat ADP8322 tripping rcd.
It is all in the research 😀
Got to test you guys sometimes !! 😀 All a bit of harmless fun.
Please stand by my last post though, it is all fact.
Cheers
Re: diplomat ADP8322 tripping rcd.
When you say it trips the RCD do you mean the RCD or the MCB?
An RCD will not trip on overcurrent or short circuit current. If it is the RCD that is tripping then you have a fault between either live to earth or neutral to earth. This could be caused by dampness, cable chaffing or overheated cables terminals tracking to earth.
For the record an RCD works on a current balance system. The unit measures the current leaving the unit and compares it to the current entering the unit i.e. current in live conductor compared to current in neutral conductor. If the currents are the same then all is ok, the RCD won’t trip. If the currents are different then this indicates a current leakage in the circuit to earth, hence the unit trips. No amount of overcurent will trip the unit, that is why the RCD must be protected by an MCB or standard fuse.
For these reasons I suspect an earth fault of some sort probably caused by ingress of water. Try disconecting the pumps and bell them between live/Neutral and earth/casing. See what reading you get, it should be Megohms. Also try this on the heating element as elements are prone to trip RCD’s due to breakdown of the magnesium oxide powder insulator between the casing and the element wire. The mag powder is hydroscopic (absorbs moisture) hence attracts problems in damp conditions.
Hope this helps
P.s if the unit is an RCBO (combined MCB/RCD) its all a different story, as these units will trip on overcurrent too !
Re: The use of PTFE Tape
Compression fittings utilising an olive do not require PTFE tape due to the fact that the olive performs the seal between the pipe and the pipe fitting. This is the true for both gas and water fittings.
Gas approved PTFE tape should be used on all threaded fittings along with jointing compound.
Hope this helps.
Re: Help required. Washine machine broke
Hi Kwat,
just read the first part of your post ???? Not sure what you mean ??
As you know my email address then you know why I dont use my real name …to avoid racial abuse that I sometimes get when posting on message boards with my real name….

Hi Kwat,
Ok no problems, maybe i’d better contact an expert to help me before I electricute myself !!!
Thanks anyway

Re: Help required. Washine machine broke
Hi Kwat,
The spin part of the cycle is at such a fast speed that it has started to rip the clothes inside. Sounds like a 747 jet at full tilt !
I’v taken the lid off and had a poke around and some of the wire going to the engine that spins the round bit seems to have melted and dripped round the plug part of it.
Not sure whether to take the engine bit apart and have a look..Any ideas here?
Ken
