One for the vaillant peeps , this part here has a hole ontop that you can see inside and its full of water leaking , is there a service kit available for it am guessing ?

 

[villa_tom]

I know you can just unplug the electrics and unscrew the top bit and change that, if that's what you mean lee

 

[Barry98]

Is there a seal though behind that screw bit ? Cant see how waters getting in . Am off round tommorow / Friday and want to take kit with me if there is one

 

[bigads28]

Nope you gotta replace the whole thing, its been updated.

Pull off the plug and the brass nut holding the motor in can be removed.

Top tip, stick the new o rings to the boiler not the valve with silicone grease, you'll see what i mean when you do it.

Think the glowworm one is the same and cheaper. It's exactly same part. (Diverter)

It is the same. The motor was changed and had a update on the harness so you need to check the cable comes with the new one to adapt.

 

[Ollieg]

It will with a vaillant part. Also on a pro the new one will be plastic even if the old was brass.
Your not being hard done by.

 

[RoryD]

Yep, it comes with an adaptor kit...another Vaillant rip off. I used to love these boilers but now I see them for what they are. What with this, the combustion chamber seals and the thermal fuse con, this boiler will eventually empty your wallet.

I changed a diverter last week, can they be done without removing the pump?

 

[Ermintrude]

Yes. Easily

 

[Leo21]

Yes. Easily

Do you move the pump at all?

 

[bewsh]

Nope, I've never had to move the pump. They are easy to replace.

 

[Ermintrude]

No just undo screws pull out that circlip and bobs ur uncle

 

[Leo21]

I'm not getting this tbh, the diverter locates in to the pump. When I tried to fit the diverter, pushing it home to the right on to the pump the rubber seals moved. And it's really tight on the dhw flow sensor.
im obviously missing something.

 

[Ermintrude]

Silicone grease by sounds of it

 

[Leo21]

I use the silicon grease to stick the seals on, but can't stop them falling of as I engage the pump.

 

[bewsh]

Are you putting the o-ring in the pump or on the diverter valve?

 

[Leo21]

Are you putting the o-ring in the pump or on the diverter valve?

On the diverter valve. If you lads are doing it without moving the pump, it obviously can be done. But I can't get the pump engaged without the back seals moving.

 

[bewsh]

It can take a few attempts, but once it's lined up, a good push will slot it in to position.

 

[Ollieg]

Undo the bottom left screw on the pump (not the head). This allows you to twist the pump head away from the upstand. You can then insert the diverter with about 10mm clearence on the 2 seals. You then push the whole lot back.
If the boiler still has the rubber hoses you get quite a bit of movement on the pump this way.

 

[bewsh]

I've never had to do that, but I'll keep that tip for if I'm ever struggling to fit it back in properly!

 

[Ollieg]

You don't have to do it but it does make it easier. Give it a go.;-)

 

[stevetheplumber]

theres two screws up through the bottom of the boiler that hold the pump in place if you take them out it makes changing the divertor easier half hour tops once its drained
