I hope the STW can help once again. Pregnant wife and facing the second night without hot water or heating. I have tried everything I can. Too poor for a plumber
System was working fine, now boiler fires, quickly reaches temp and cuts off.
Both on CH and HW, both have separate motorised vales which both work so not the issue. Pump works and spins fine.
Full system has been bled including boiler (worcester greenstar ri open vented system).
I thought it may be an airlock hence full drain down and refill. No luck
Bled boiler no luck
Bled pimp no luck
All radiators bled no luck
