Just an update to close this thread, the problem did turn out to be a faulty 230v Controls Interface board.. Replaced it today and i have a normal working boiler again. Thanks for all you suggestions..

It was a refurb PCB with 18 mounths warranty, but the fault is the same as when I had my original PCB in, however my original HW and pressure issue has been sorted by the replacement just the CH issue remains. All the jumpers remain the same on the interface board, this board hasn't been touched.

With flow sensor (Assume this is what you meant by hw turbine) disconnected the heating still come one straight away.

Connections on the board all look good. I tested the Thermistors again at Room Temp and both read around 11000 ohms. I've removed the diverter valve from the LH Hydroblock and it didn't look too bad so gave them a good clean and made sure everything moved freely, put everything back together and...

I tested the Thermistors on the boiler itself, the return pipe was warmer than room temperature so I think 9 was reading ok, probably would have been in 11,000 and 13,000 range at room temperature. The link I was testing was on the voltage free heating control plug, this is normally not present...

Managed to check them tonight, setting the multi-metre ohms range to 200K I get the following readings: CH Flow Thermistor 12.3 and on the Return Thermistor 9.1 so I think these look ok.

Thanks, I'll test all the thermistors I can find tomorrow!

Oh Ok... Found that bit in the manual after seeing your picture, The manual shows G.C. No. 47-047-24. Should I be testing the Thermistor CH Flow and Thermistor CH Return? In the wiring/parts diagram I can' see anything that specifically refers to the frost protection device. Thanks for your...

Hi Picasso, As far as I can tell the optional frost protection isn't installed in the boiler itself, the wire for this feature going into the mains voltage heating control plug isn't present. Instead I have a British Gas FS1 that is linked to the WR1 wireless system so if this was faulty I...

Hope someone can help with the following... I had an issue with No Hot Water and after going to the boiler I noticed the Pressure was going all over the place 0.5, 0.8, 1.2, just cycling through different pressures and the fan was making a whirring noise. I turned everything off and removed the...
