Washer drain pumps

[allan73]

Does anyone know if all pumps on m/c are fitted with internal TOC’s these days ?

I seem to be getting a run on burned out pumps causing board damage lately…..

Re: Washer drain pumps

Very few are fitted with TOC’s. Zanussi washer dryers are the only ones I’ve come across. And you can get the ‘standard’ Askoll pump with a TOC fitted cheap enough to fit all if you wish.(Qualtex PMP243)

HTH? 🙂

Once again thanks for the help Martin, I have fitted those askoll’s with the toc in the past i think.
Would it not cut down on board problems though if all pumps came fitted with a cut out or am i clutching at straws here ❓

Possibly in certain cases it would avoid board problems in that a faulty overheating pump would at least be monitored by an integral TOC and shut down before it blew the board perhaps? Though having said that the only real effective way boards can protected from devices that go faulty, like pumps and more pertinently door interlocks is by using in-line fuses. 🙂

Yes, it might be worth checking how much the current goes up when you stop a pump from turning. I don’t know if the coils can get hot enough to cause shorted turns. Like most of us here I’ve removed all sorts of things from pumps, coins, bra wires, bolts, rubber bands, nails etc. If it pumps OK with the obstruction removed you tend to assume the pump is OK but if it now draws more current due to shorted turns it could still damage the electronics. 😕

Martin, to save me the bother of trying to remember my Qualtex password, how much is PMP243?
TIA and sorry I called you an o.g. 😆

Re: Washer drain pumps

£9.75 😯 No point me remembering that password then. Just like everywhere else. For years you get used to pumps being £3/£5 and then suddenly they hike up all the prices. The cheapest with TOC I’ve been able to find of late has been the WMA one which at CDSL is £9.95 although I think Masterpart do two for £7/£8 each. It’s a Playset one of course and with reverse terminals, so won’t fit all. At one point I looked into the possibility of buying the TOC’s from RS but they were a bit pricey and would be fiddly to fit.
Also you can often get fooled by a picture of a pump which looks like it has a toc because the terminals are placed a certain way (Askoll) and/or there’s a raised compartment on the coil cover (Playset). When it arrives you find that was just an empty promise.
I don’t know if a toc protects the pcb but that picture on here somewhere of a pump that caught fire made me wary.
