Hi all

i have the above bcombi boiler that has recently ceased to work!
There is a red led that is flashing on the front and going by the fault finder in the instruction book it points to a fault with the pressure sensor.

Couple q's

The pressure is showing at 0.4bar but when opening the fill loop there is no action, no water flowing in or out is this correct if it was a sensor?

i have cleaned the filters and they were fine.

is it a big/hard job to fit a new pressure sensor if this is the problem?

does anyone have any guides on how to?

thanks

can anyone tell me if this could be as simple as the pressure sensor please??

It's not the sensor - it needs to be refilled.

If no water flows when the fill loop is open, either one/both of the valves has seized, or there is a blockage.

how do i clear and where will the blockage be please

First you train to be a plumber and buy yourself a set of tools.

Then you carefully dismantle it and test it in stages.
