I have the old one back on, you couldn't see the switch without stripping it down, I will keep the new one incase it's needed. It looked like someone had been into it before, rounded screws etc

Hi mate, managed to get it all working eventually! As you first mentioned it was the switch inside the actuator. I stripped down the old one and could see a couple of small rounded screws so managed to get the actual inside actuator off and could then see the switch was held in woth 2 plastic...

Sorry my mistake, didn't reset it after putting the power back on. So with the orange and greys swapped terminals this is what happens - No program selected - grey 240v orange 0 HW on - valve opens grey 240, orange 0 CH on - valve opens, boiler comes on, grey 240, orange 240

Hi mate. Tried that, removed both orange and greys. Tested terminal 7 and was 240. Swapped orange and grey terminals, boiler not firing up on either HW or CH, the HW valve opens though as normal.

Thanks, I will try that in the morning. The actuator come with a new cable already fitted.

Just check the voltage on grey again and it goes to 240 when the CH is activated but only 0.2 when HW activated. Is this the issue?

Hi. HW only selected is 240 on terminal 8. With actuator removed, it functions as if to open the valve but still no boiler. Checked again and at this point orange is 240, grey is 0.2. Valve is moving freely fully open and close. Tested again and still no boiler!

The new HW cable is the right side black one on the bottom of the photo. With HW and CH off at programmer, the grey reading is 0, orange is 240. With HW on at programmer, the grey reading is 0, orange is 240. With CH on at programmer, the grey is reading 240, orange reading 240.

Yes got a multimeter here. So there is 0.00 reading on the grey wires with HW/CH program to off. The orange wires reading between 14.00 and 16.00 with both HW/CH. When I select HW on still 0.00 on grey wires. When I select CH to on the grey wires then read 16.36 jumping back and forth to...

Hi. Nipped to screwfix and got a replacement actuator. Same Drayton one but newer style. I have wired that in. Set the programmer to water on, the new actuator is operating as it should be still no boiler coming on!

Just to confirm, the valve with the white plastic actuator is working when I select HW on and off, as you said boiler not firing up though. Is this wire you suspect to be faulty going from the programmer?

Thanks. What valve is the hot water one? Is it possible to but a replacement actuator? Screwfix maybe

Hi, it's a oil boiler, heats bother water and heating. Approx 10 years old. That's the valve set up in the photo.

Hi all, Just wondering if anyone has come across a similar issue? Boiler is Worcester greenstar utility 32/50. A few monthes ago the boiler stopped coming on when the hot water is turned to on on the control unit (Drayton). Just doesn't make any noise and doesn't fire up. It fires up no...
