Servis Quartz Plus tripping household RCD

[dunderhead]

Hi all,

We have a Servis Quartz Plus model 6033G No. 000189. This morning it started its first fill then, before it was full of water, it tripped the household RCD. After unplugging the machine and resetting the RCD, it trips the RCD almost instantly – the middle LED on the display flashes briefly (like a “-” symbol), then the power goes out.

I’ve visually checked the mains plug, amins cable, and circuit board, which all look OK, and I’ve resistance tested the fuse in the plug and the heater element, which also seem OK. Any ideas?

Thanks in advance.

Could be many things including the motor. This machine must be 30 years old and 80{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of the parts are obsolete. Time for a new one really. 🙁

Yep is an old one alright, but before scrapping it its worth checking the door switch and associated wiring also you say you checked the resistance of the heater but did you check to earth as well as the heater itself also try disconnecting the secondary wires from the mains filter and switch on if it trips change the filter, hope this helps

Nah, mate. She’s only 22. We hope there’s plenty of life left in her yet.

[Thanks for that – I may have missed it if it’s earthing – see below :boops: . Back to the old multimeter!

Anyway, things have got more interesting. The wife suggested trying it again since kit seems to like me and problems sometimes just go away when I’m around (when I was in IT Tech Support it was suggested that we should sell life-size cardboard cutouts of me to stand in customers’ machine rooms, as nothing would ever go wrong!). When I did so, all seemed normal, so I tried a spin cyccle – all OK (drum span, water left in machine pumping out). Cancelled programme and let it finish pumping out. Put a small load in and started programme 6 – machine started filling and agitating for a couple of minutes before tripping out the house RCD as before. I suspect it is the heater after all, as the “heating” LED hadn’t come on before everything tripped. Here’s hoping!

Sorted. It was the heater – many thanks the Ron of Ron’s Repairs for talking me through the problem – its resistance was too low, so the heater was trying to pull 5kW!. Anyway, a neighbour let me strip her old Servis Quartz when it died some years back, and I luckily had the heater from that, which did the trick.
