Vokera Option - red light flashing and rapid clicking sound

[jhodgski]

My Vokera Option boiler was playing up for a while - only heating water for a short time (just enough for a quick shower) but now it's not heating at all.

There's a red flashing light so I opened the front panel and saw the water pressure was at about 0.8.

So I let some water through and something in the boiler started clicking really rapidly - maybe some kind of valve opening and closing repeatedly.

So I stopped what I was doing as I wasn't sure if I may be damaging something (as I was thinking maybe the pressure gauge could be dodgy).

Anyway, I thought I'd better come on here for some help.

Thanks in advance,
James

PS - Have also tried turning it off and back on. There's no central heating and no hot water for the the taps.

Time for a GSR engineer to be called to take a look. Could be a number of things but will require a professional on site.
