Vokera Excell 80E Leak

[stewcant]

Hi I have a leak coming from the brass section behind the Flow Micro Switch.

I was wondering how to fix this? Is it just a case of buying a flow diaphram and replacing it or is there more to it?

Thanks

It wont be the diaphragm causing the leak. There is a seal around the flow switch pin with a nylon seal in it most probably will be that. Vokera part number 6919. You can also get a service kit for these boilers that comes with all the seals and diaphragms to repair it..T0019...cheers

Thanks for quick reply.

Would you be assuming that the leak is coming from the small gland that goes into the middle of this section?

As the leak is coming from around the edge of when the brass section attaches (the brass section being the one that is connected with 3 screws.

Best ordering the service kit then, inside the valve there is a seal shaped a bit like a figure 8 If you order the service kit then it will come with all you'll need to fix it..cheers again

So to change this out do i only need to remove the 3 screws to remove that brass section?

If its around the edged the diaphragm inside creates the seal between both sections. Cleaning the brass and replacing the diaphragm should rectify this but I'm pretty sure it all comes in the service kit. There is no harm in replacing the lot

The only harm is on my wallet

They're not expensive and as i said you'll have everything you need to fix it.

I had a look tonight an it seems pretty hard to get to all three screws. Just worried if I remove them will I get them back in tight enough without messing up the screw head? Do I need to remove anything else to make it easier? Thanks

The diaphragm inside the valve creates the seal. Order the service kit easy job,drain the ch system,open the valve,replace diaphragm and front seal,add inhibitor to system,fill up and bobs your uncle etc etc.
