GLOWORM 30 CI *F22 *

Post  tommy nash on Mon Feb 22, 2010 11:25 am

*has heating no hot water*

symptoms are simlar to a scaled plate heat exchanger

when in demand for hot water boiler fires , then turns off,
displays f22 ==manufactures say replace pressure switch.

actual fault was insufficiant gas supply at boiler.

standing pressure = 20 mbar
working pressure = 8 mbar

checked gas meter (under a pile of stinking shoes) and ecv was 3/4 closed .

Good one that Tom. Just shows the benefit of checking inlet working pressures and preliminary electrical checks on every job!! Wouldn't help with the shoes though.
