Can anyone help
I posted this in the central heating forum and was advised to try this forum instead. It's looking like this is my last attempt at a diagnosis before calling out an oftec engineer
My problem
1. I came back from a weekend away to find my boiler with no pressure and a circulating pump making a strange noise, no lockout was showing.
2. I changed out the pump, found why the system had lost pressure( blocked expansion vessel hose caused the PRV to activate. no inhibitor from the looks of the gunk coming out when fully drained.)
3. Repressurised system called for hot water and heat, circulating pump runs, no lockout
4. Boiler didn't fire so I pressed the manual override button on the underside of the control panel.
5. Got a blown 3amp control panel fuse for my trouble!
Where do I go next, is it the pcb thats knackered or is it one of the thermostats or something else?
would a knackered manual override thermostat stop the burner from firing up or has it blown the control unit on the burner unit?
its very cold up here so any help to get us up and running again would be hugely appreciated.
