Baxi 105e

[DellBert]

Hi,

I wonder if I could ask for a little advice, my Baxi 105e Combi boiler has developed a leak, for the three-way diverter valve, could this be caused by the diaphragm? The water that is coming out is from the Central Heating system.

Yes you could, no it couldn't, and you'll find all manner of pictures and things if you do a search
But come back if stuck

 

[namsag]

Exactly where is the water coming from is it from the pin at the front that strikes the microswitch

I took a couple of pictures the other day, I hope this helps, its leaking from around the pin shown here:

You can see the disclolouring.

Thanks for the speedy responces.

Easiest (not cheapest) option is to change the valve Prt No.248062,
or Prt No.248061 has the dhw pressure differential included

 

[DellBert]

Am I right in saying that 248061 - Hydraulic Outlet Assembly also includes the 248063 - Pressure Differential Assembly.

Because last year I had a new 248063 fitted, just after British Gas carried out a full service and gave it a clean bill of health.


I was wondering if the 343565 Diaphragm - 3 Way Valve could have a split in it causing the leak.

I know sometimes it's easer to replace the whole unit rather than individual parts.

It look's as if it was the Diaphragm after al, I got one online and fitted it two days ago, the one in the unit was almost paper thin and breaking down at the edges.

It took me about an hour to shut down, drain and fit, and than drain back online. two days later and no sign of that leak.

And your corgi registration number is..............?

Why does he need a CORGI number to change a diaphragm.
