Bleeding rads today, pressure dropped below 0.5 bar and triggered F05 fault. Located overheat thermostat but button not obvious if it was switching or not, no click, nothing didnt feel like it was moving.
rigged a test lamp as no voltmeter, removed switch, lamp lights across the terminals but not between a terminal and the front of the thermostat.
duff switch??
Should add that no power appears to be getting to the boiler. Was fine turned it off when flashed F05 then nothing on turning back on. Fuse or ovheat switch?
thanks
