Expert:  James replied 12 days ago.

Glow worm flexicom 18hx
Expert:  James replied 12 days ago.

F22 suggests the water pressure has dropped below 1 bar, can you see a filling loop under the boiler?

Customer: replied 12 days ago.
Where do I see that?
Expert:  James replied 12 days ago.

Can you see the filling valves shown at the back of the boiler as shown in the video here

Customer: replied 12 days ago.
Cannot see the valves
Expert:  James replied 12 days ago.

There is no need to open the boiler cover the valves would be on the underside of the boiler, in the first picture look where the white power cable goes and you should see the valves in there next to the yellow gas valve

Customer: replied 12 days ago.
No white valves
Customer: replied 12 days ago.
Cannot see any valves, could they be anywhere else?
Expert:  James replied 12 days ago.

It depends on your installer it may be on the top of the boiler or if you have a hot water cylinder they may be in the airing cupboard.

Customer: replied 12 days ago.
This is the top of the boiler
Expert:  James replied 12 days ago.

Thats your flow and return for central heating coming from the top.

Customer: replied 12 days ago.
no valves
Customer: replied 12 days ago.
Where can I find them? Sorry no idea how to fix this
Expert:  James replied 12 days ago.

Correct, if you cant find them a Gas Safe visit will be required for them to trace the filling loop.

Customer: replied 12 days ago.
Ok, thank you for your help
Expert:  James replied 12 days ago.

No problem, would certainly be worth checking your airing cupboard if you have one though.

Customer: replied 12 days ago.
Can I just ask you one more think we do have a airing cupboard on the third floor but this boiler is on the ground floor do you think that could still be there even if it’s on the third floor
Expert:  James replied 12 days ago.

Yes, if it was in the top floor it will have a pressure gauge next to the two valves and a flexible hose connecting the two valves.

Customer: replied 12 days ago.
Cannot find any valves there either, thank you for your help anyway
Expert:  James replied 11 days ago.

Have a great day
