Combi compact hre 28/24

[Tomk099]

Boiler is showing pressure at 0.0,
Tried filling from the loop but it does not change at all.
I cannot access the clock to check if the time is correct, because of this.
I have hot water and heating.
Any ideas as to what is the problem?

If you're sure you have pressure in the system then most likely a failed pressure sensor

Pressure sensor was replaced last year

Pressure sensor was replaced last year

Doesn’t mean to say it’s not failed again.

Doesnt mean it hasnt blocked up again

Ha Ha snap

 

[Tomk099]

It was doing exactly the same before the sensor was changed and changing it didn't resolve the issue

Are you sure you don't have a leak?

These boilers will run perfectly happily with the pressure sensor disconnected

 

[Tomk099]

No signs of a leak,
I might have a look tomorrow and disconnect the sensor

Do not do that.
Disconnecting the sensor- is for open vented. You want to kill the boiler, go right ahead

Do you know for a fact boiler is not ejecting the system water? If the previous pressure switch was replaced because it was blocked with crud, no reason why same sediment could not be the case of system
Losing pressure

 

[Tomk099]

I can see any signs of ejected water.
The old pressure sensor wasn't blocked as far as i remember

Why wait until now to ask about it then? Does the heating and hot water work?

Does it sound like the system is full?

 

[Tomk099]

I have heating and hot water.
I believe the system is full, bled the rads and no air escaped at all.
There is no fault light displaying as per the manual.
