No the panel read stupid stuff before i changed the pcb, and yes the pcb was from Ebay, even I'm not unlucky enough to get 2 pcb's doing the exact same fault though. :?

HW still working normally after swapping the thermistors Tony, but worked for a week after swapping the pcb last time, so not holding my breath, starting to think that it could well be a problem with either the wiring harness or the girlie pink pcb, will keep you both informed if or when it...

Can I wire this out to test?

Thats Yorkshire, he has been drinkin! :wink:

Thats not Cherry its more a girlie pink, no I havent changed that one just the main pcb behind it, I have checked all the spindles though and they are all intact for now, checked the operation and all dials seem to respond to command.

Which other circuit board, the one foremost at the front underneath the main board, where the dials go into? This is giving out stupid displays. Steve.

Working fine at the moment but it usually does for a couple of days, will let you know Tony, but call me pessimistic but I've no confidence in this boiler now. Steve.

open circuit it reads 1meg closed i.e when the water is switched on it reads 1.4 to 0.8 it varies, and I've swapped the CH and DHW thermistors over about an hour ago. If it were the Flow switch why would it divert the water down the CH and not just just turn off the gas burners, and why would it...

My multimeter does not go low enough to measure the closed reading but when opened the reading starts at 1.4 and does vary down to 0.8. I have just changed over the NTC sensors now. Steve.

Right here goes! In standby mode the two purple wires read a constant 10.2v and low and behold when the HW tap is turned on this disappears, but the problem is still there (hot water down the CH not out the tap) voltage doesnt come back! Checked the resistance with the wires off and my meter...

Will check the voltages tonight when I get home from work and try to work out how to check the resistance, will post later if you could both make time for the results, Is the flow switch and easy repair what else other than this could it be? Steve.

All the above I've mentioned before but I appreciate you both are not concentrating just on this post like myself. I agree with you Tony the problem is simple but whats the cause? Again..... The pcb that feeds the actuator is swapping the signal (brown & black) when only the hot tap is on...

---------- When the hot water flow switch is "on" there should be 0 Volts DC across the purple wires When it's OFF there should be nominally 5Vdc. To get the actuator into DHW position there should be mains across connector M11.1 and M11.3 (measure with the connector in, at the back of...

What do i need to do to check the flow switch? just had a look and there are two purple spades on the switch that go to (M5) 5 and 6 pin as previously mentioned, also just removed left hand spade on the switch to stop any short and noticed the boiler kept running, flames an all but the hot water...

This I am sure of, The 230v switches from black to brown ect when the water goes cold definitely not both on together, the hot water will work fine for a couple of days ect, but when it goes off the burners remain lit and the motor actuator pin goes in and out not every 4 secs but...
