Perhaps those yet to be convinced how critical casings are should take a look at the obsolete Netaheat boiler range...a boiler implicated in the deaths and CO poisoning of several individuals. Clearly now, I am fearing the worst that I have potentially blown my PCB by using a pump it can't handle, despite the allowance for the plug it has and my confidence that I was provided the correct part for the exact boiler. And of course doing a search for "5 wires" shows adverts for the pump stating "5 wires only". Hi guys, my first post here, but I won't lie, I've used this place as a reference point so many times it's been invaluable, so I thought I'd sign up and ask a question I have. I will give as much info as possible so forgive the long read... Not what you're looking for? Try our unique Spares Finder tool or you can view all Vaillant Boiler Spares products.

Vaillant 178983 Pump Complete - Genuine Vaillant Part

I would not intend to wire in anything that was not meant to be, but when I have provided exact numbers requested for the boiler, been given the part which correlates to this number and the PCB has the correct plug to connect to it... I would not assume it is incorrect. However, changing the pump was identified as being all water side which I felt absolutely fine doing, and it went well with no leaks and no breakages with all seals replaced and parts cleaned along the way to ensure good seal.. As far as I could tell, it was a straight swap. Hence where I stand asking the questions I do. Why have I been given part 178983 (which is the only part number found anywhere that's for this boiler) and yet it cause some kind of issue? The VAILLANT 178983 PUMP is a genuine, brand new Vaillant Boiler Spares product, covered by a Vaillant Boiler Spares manufacturer's guarantee. Product Information: The pump is usually located after the primary heat exchanger within your heating appliance and allows the heated water to be moved around within the closed heating system. In combi boilers , the pump is usually situated before the diverter valve to allow circulation through the DHW and central heating systems.

The cover on an Ecotec forms part of the safety's correct fitment is essential to preserve the safety of the boiler....especially on a boiler that has a history of combustion related safety issues. Total system solution available from one manufacturer – Intelligent controls and accessories available There has been a distinct blurring over what constitutes a combustion chamber cover on the forum over the last few years.

Frequently asked questions (FAQs)

Are there other parts on the PCB that would prevent correct operation of the boiler if it were to match the 5 wire pump setup? If you have changed the old 3 wire Wilo pump for an updated Grundfos 5 wire pump without issue previously, that's the kind of info I'm after. As I said in another post, I would expect that having given the correct details and the fact the PCB has the correct plug for taking a 5 wire multiplug, it should work. But after carefully noting all parts I did touch during removal, ensuring I worked in reverse and didn't do anything to the electrics other than unplug the old pump from the board and plug the new one in, I'm stumped as to what might be preventing it from working. Nothing felt like it broke on the PCB when I unplugged the old pump, the new plug went in ok, there are no obvious signs of burnout on the circuits, I had no leaks, no leftover parts, all seals were replaced and all mating surfaces cleaned prior to new seals being fitted... I was honestly surprised at how well things went until that point of turning it on. I'm going to call my supplier tomorrow for their opinion, but I'd like your input too so I am armed with as much info as possible. Prior to fitting the new pump the boiler did fire up and try to work so all was well apart from the pump being broke. If I now plug the old pump in (despite not being plumbed in) it still does the same thing. I changed the fuse on the PCB too in case that had blown during the switch on process (tried both the spares attached the the plastic casing, there's no guarantee they were both ok, but I would be confident they haven't been changed prior and so expect them to be ok). What would my rights be now that I've fitted the part and filled it with water but was not asked or offered whether it was 3 or 5 wires?
