Have replaced plate to plate Also non return valve This sorted the pressure problem However the ch is constantly run even when the thermostat is off I haven’t touched the wiring at all and it worked fine before

expansion vessel is pre set to 1 bar. I haven't tested the filling loop and yes, the pressure continues to to rise when boiler isn't working. sorry I don't understand the "plate to plate" bit, what do you mean by this??

I have the exact symptoms on my boiler I have changed the EV and PRV as well as the Flexi hose but still leaking PRV How did you manage to fix yours?

Hi guys Anyone familiar with Grant oil boiler? The boiler is consistently overflowing and the water from overflowing is rusty I have been told that the expansion vessel is dead I have decided to open it today and the water is completely rusty as you can see How do l know if it’s actually...

I have also noticed that there is a small amount of drips here circled in red when l try to up the system pressure.

I have the exact same problem I have ordered expansion vessel and PRV to replace. Should l replace the PHE as well?

Im having the same problem The hose is gone all black What type of hose did you use?

Thank you so much this worked, l had to link 25 to 26. Also switched CH button on the boiler to Timed. Also managed to disconnect the switch old thermostat now l do have 2 extra cable core. I will replace it with 3 core cable. Thanks everyone.

So l tried it There is a link between 17 and 18 already 19 to 1 on hive And 20 to 3 But the heating doesn’t come on What am l doing wrong Also removed 25 and 26 where it says ROOM STAT so assuming that is for the thermostat

And how do I disconnect the current thermostat? Im struggling to find the wiring to the current thermostat

I have also found the manual for the wiring

Sorry l meant Honeywell Autocorrect!

I have made a video of boiler board
