It still fires up but cuts strate out
Intially no codes
Then Code f22
Then code 72

No pressure gauge on this model , I cannot locate filling loop n even if i could how would i know how much with no gauge .
Secondly i was thinkin air in the pump n been tryin n to unscrew the bleed screw on pump but it is firmly stuck
The pump gets hot but pipe leading off from pump get just slightly warm at the start the rest of pipe is cold .

There should be a gauge on the front, is it the blue lit digital type? If yes, then press a button to wake it up, and look on the right hand side of the screen, there’s a digital gauge there, usually 2 sets of dotted lines, pressure should be between these. Secondly do you have a cylinder? If yes the filling loop could be located there.

400 series is open vented so no pressure gauge, check that you have water in the header tank in the loft.

Seized pump - perhaps that was the noise you were hearing? Try to get that screw out and see if you can turn it with a screwdriver.

Hi thanks for replies
I have water in the tank in the loft
I have a digotal reading of pressure which says 1 bar bit if i needed to put more in u cant see a dial like u can on other boilers
I tried for ages to get that bleed screw out of my pump but it wont budge at all i tried with various screwdrivers n it wont move at all .

I will post some pics of my set up in a min so u can see what type it is .

Photo of paint doesn’t really help, sorry.

As others have said, the pump could be siezed/stuck, especially if the pipe from it is only warm.

 

[Bexster]

Ok thanks
Yes the pipe right next to pump is warm but nowhere else
Pump is definitley louder now

 

[Bexster]

The bleed screw is certainly stuck it wont budge at all
I got my bro to try n turn it too n it truly stuck .
Anyone any udeas of ways to free the bleed screw

Why is that lever valve closed?

[CBW]

Which way are you turning it? Are you using a flat bladed screwdriver?

As already pointed out mate the red lever valve is the cold water feed to the system, why is it closed ?

 

[muggles]

That lever valve should be open, I'd guess you've starved your system of water. You shouldn't have the casing off your boiler - it forms the safety room seal and should only be removed and refitted by a Gas Safe Registered engineer

As other have said you need to open this valve and leave it open do not close it again , 1/4 turn to open it
