Logic System 18 boiler - F1 error

[Rob70]

Hi,

Got an F1 error (bled a radiator this morning), which means that the water pressure is too low for the boiler to fire. As far as I understand I should just re-pressurise the system. This shouldn't be too difficult and I've done it in the past on another boiler, but no matter what I do it doesn't seem to work. CH flow on the left and CH return on the right - see image below. Turned each of them on / off and both of them at the same time, but no luck. The water pressure doesn't go up. Help please before I freeze my b(&^ off and / or run out of wine.



Many thanks,

Robert

There should be a filling loop on the system somewhere. A small braided hose usually with levers on to let water into the system. Is there one near the hot water cylinder?

Just found this, but can't seem immediately where it'd connect to.

All sorted ederz! I figured out where it all connected when I found the hose. Thanks for your help!

leave the flow and return valves alone, and search for the valves to assist you top up the pressure. If you can follow the return pipe from boiler, that might lead you to it.
ederz, it is unlikely there is a hot water cylinder.
ok, there is a hot water cylinder. check in there as ederz suggested. I nned to get orf this drink naw

I thought it was a system boiler. Not a combi?

You were right ederz. Like I says, it's the drink gettting to me, honest. Haven't stopped since 9am, and the wife keeps plying me with more. Wine, Guiness, champaigne, bailleys, I'm beginning to think there is a motive to all this drink she is plying me wiv?

Probably - don't agree to anything!!

 

[Crinkmeister]

I'm guessing you have found the filling loop by now?

 

[ederz]

Either that or a jumper haha

 

[Rob70]

All sorted now. Thanks! I think my posts take a while to get through the approval process.
