On the off chance anyone has the same problem, I got a 3rd party Worcester engineer round yesterday. He said it could be the PCB but wasn't sure. Quoted £550 and to try it with no guarantee of a fix. Once he left I removed the PCB to check for damage. It looked as good as new but I cleaned the...

Thanks for your help. I had a Worcester engineer come and say the boiler probably needs a new PCB but can't be sure (will cost me £600 to find out!). I decided to take out the PCB to see if it had any obvious areas where it had blown. It looked perfect. Connected it all back up again and to my...

Sorry, I didn't get a email notification so I've only just seen this. The valves are both fine, the terminal that powers the valve to open (PZ1) doesn't get power when calling for heat. When directly powering the valve it opens and sends voltage back on the orange cable when it fully opens. Hot...

I have a Worcester Greenstar 27RI compact boiler downstairs which is connected to a Greenstar Wiring Centre upstairs next to the hot water cylinder. The wiring centre talks to the boiler on an eBus connection. About a month ago I connected a Tado stat to the wiring centre on IZ3 in the wiring...

I guessed 15mm, wrote 50mm, then just measured 12mm. I'm going to bed and will try again tomorrow

Hello, I found out our shower was leaking quite badly after the downstairs living room electrics blew. The water was dripping down a panelled fake chimney so I didn't notice. I can see in one corner the silicone has cracked and it looks like the shower has sunk in that corner quite...

Thanks very much. Yep that would be way out of my comfort zone, but I think you've saved me from getting an electrician in to install the Hive I bought, only to be told it won't work. I would really like a smart stat so I can turn on and off heating whilst away and reprogram times easily. Do you...

Yep sorry, that wasn't a great idea to send a stock photo. Here is my setup, showing the boiler wiring and the wiring centre box. The wireless thermostat has completely given up the ghost now so we are without heating. I know I need to remove the ribbon of the old controller. I assume IZ3 in the...

Thank you. I found my manual for my wiring centre and it all seems to make sense. Although not shown on photo above (I got that one from internet), my boiler does have the connected loop wire installed (at the boiler iteslf). Do I still need to remove it from the boiler panel even though the...

This is great. Thanks to both of you.

This is the wiring block on my Worcester Greenstar 27ri boiler. I just want to check that a dual channel Nest Heat Link will work with it? If it's simple to wire up, a nudge in the right direction would also be massively appreciated. Thanks very much, Simon
