Mr T

I am not sure if it has a purge mode. It could need a drain down which i will get someone in to do, i am not very competent with this stuff. thanks for the advice

Checked the vales and pumps looks good, it should have an automatic air lock release so i am assuming its not that. Think i will need to get someone out. 😣

Will give it a go, thanks

Yes the pump looks ok

Hello, we have a logic boiler and it keeps coming up with an FU error. It will start up and the temperature shoots up to 80plus and the error pops up for a minute then it drops back down to 60 and starts the process all over again. Is there an easy fix for this that anyone is aware of or do i need to call out an engineer to have a look at it? thanks for your help
