Hi our vokera linea 28 boiler is showing an intermittent 01 fault in ch mode, sometimes water too and going to lockout. Our plumber has changed both NTC sensors and the main pcb. I have to now go and buy a High Limit thermostat on the advise of a second plumber. Already spent £200.
The boiler will work for almost an hour then cuts out, wont stay on after reset unless it has totally cooled down. Temperature can be up at 70c and presssure gauge seems to be all over the place. Will be 2 1/2 bar then drops to 1 1/2 or lower. The heaters are scalding when it is on.
It never shows any other fault than 01, which is an ignition problem according to the manual. Ignition parts have been tested and look ok. Dont want to fork out for ignition pcb unless we actually need it!!
HELP!
Many thanks in advance, Melanie and freezing family
