Hi,
Went to service a suprima, it's not working.
If put on a demand for Ch or hw, you hear a 'click' at the boiler, no sparking, fan does not run, the pump will spin for a second and stops. Voltage drops in and out.
Had a new PCb 6 years ago.
Customer said this has been happening since he drained the system and fitted 2 new rads. I put a magnet on the separator and it sticks good and proper. I said to cust, likely blockage on cold feed. He has since repiped and said boiler doing the same as before.
I'm thinking aps or PCb.
Any other ideas? Thanks
