Frost Damage Vaillant (1 Viewer)

[mistyb]

Hi everyone,
We have a G Reg Talisman with Vaillant 125/7 water heater. I have read the previous thread and I'm hoping you can be as helpful to us. The worst has happened and we have frost damage to our water heater (please don't shout I'm kicking myself enough already). Water is running out from where I can see the edge of a diaphragm. Could anyone help me with instructions on repair? I can see four screws holding the housing above the diaphragm in place but can't figure out how to remove them (there doesn't seem to be any room to work.) Also is it normally just the diaphragm which needs replacing? I'm not trying to pre empt taking it to a professional, but we can't find any local in Northern Ireland and we have already booked a winter break.
Any help greatly appreciated.
Cheers
Brian & Denise

Hiya,

Did you manage to get a diaphragm for your heater? If you did and you've had a go at fitting it, was it easy to fit? I have the same problem on my heater, the water has been drained (by the previous owners I presume) and my local service centre says I need a new boiler because of the diaphragm being damaged, but I am sure if that's the only problem I can just fit a new diaphragm. Did it fix your problem? Many thanks, Debbie.

We did one on a friends a few years ago no problem worked perfectly after, so worth a try.


Best of luck

Diaphragm Repair - Vaillant heater

I had an Autosleeper Flair in a ford transit it sufferd the same fault nearly every year I tried allways to drain the heater even used air line the first time I bought a new diaphragm after that I took the diaphragm off and rubbed down on fine wet and dry placed on a surface plate as you drew it across the first few strokes you could see the twist in the diaphragm just a drop of water left in the diaphragm housing and the poor wall insulation was enough to freeze and twist the diaphragm.
If no surface plate use a piece of plate glass if possible but watch the edges

Hi I have a similar problem. The heater diaphragm, when removed, had been badly inserted at some time and had a fold in it. Resting it has hopefully resolved this but we cannot get the fibre washers for the hose connections anywhwere - does anyone have an idea of a substitute?

somewhere in the back of the shed I have an old box of assorted fibre washers. I am sure they are still available....yep still available
