Major problem with BIASI COMBI 24S !!! No hot water at all !

[DRAGONEYE]

Hi all,

I am new here, thought this a good site to get knowledge.
The problem is now been going on for the last month.
The central heating works fine.The problem is no hot water at all.
We only get hot water for one second when the heating is on.
The manual says it is either the regulation pcb or the D.h.w. temp. probe.

Is this correct? or is it the diaphram?

This is really annoying, any help would be great, we have a 6 month old baby and we are desperate to sort it.


Also if you do know for certain what it is please say where abouts the part is on the boiler and how much the cost is?
Thankyou again.
Saul

Sounds liek a diaphram, which is not expensive; but without seeing it one can not say for certain.

If you can see the housing that contains the diaphragm, then look for a pin that should pop out when the hot tap is turned on. If it doesn't then it sounds like a diaphragm problem.

Hi, thanks for your input.

I thought it was the diaphram. But in the manual no where does it say about a diaphram, is there another name this part could have?

They call it a membrane.
