Hi Eco, you very kindly gave me some advice a few months ago and I was wondering if I could trouble you again as we still haven't managed to fix our boiler (we have an electric shower so don't smell too bad!). I have a faulty F30 with a flashing L5 that doesn't fire - I changed the water pressure sensor but that didn't solve the issue though bypassing the sensor by connecting the two leads allows the boiler to fire. Does this mean my new switch is also faulty or is there something else I'm missing? You mentioned a blocked capillary in the gauge, would this be the issue? The gauge seems to work OK as it falls/rises as I bleed/fill the system.
Any help would be really really appreciated, thank you
