It works!! :))) Turns out it did just need the reset button! Honestly thank you all so so much for your help, I’m really grateful :)

Just double checked and it is receiving 240v. I’ve just noticed there’s a boiler control reset and an element control reset on the cylinder thermostat. Could either of these help?

Thank you I tried this this evening and it worked I can not turn on CH only and the boiler works and the heating comes on :) So the issue now is only the boiler won’t come on when I have only HW selected. I have retaken the readings from the wires of the 3PV.

I can’t seem to see a Gravity / Pumped switch on the back, could it be that this programmer is too old to have one?

It will only allow me to slide the CH to the left if the HW is already over to the left. If the HW is off it will not allow me to turn on the heating.

I’ve been using the immersion, but I haven’t in the last 24hrs and the water is currently cold. The terminal is currently reading 75v do you think this is due to a fault with the programmer?

Here are the readings I’ve just taken. I’m unable to take any for CH only as I can’t get this setting on my programmer.

I’m reading between earth and 1 = 240v 2 = 0v 3 = 0v The L and N go to the immersion switch.

with the programmer set to HW only, I’m reading 0v between both the terminal connected to the orange wire to the terminal of the neutrals and the terminal of the earth.

I changed the whole 3PV because the old one was a fixed unit and didn’t come apart. The whole system previously fully worked in the spring and I had HW but no CH (I left it throughout summer because I didn’t need the CH) Beginning of September I changed the 3PV and the boiler would fire but...

Hello apologies in advance for my absolute lack of electrical/ central heating/ plumbing knowledge, but really hoping someone on here can kindly assist me :) I currently have no HW or CH. There is currently no signal coming out of the 3 port valve to tell the boiler to fire up. I have tried a...
