Looking at the service manual, it says pump runs and fan runs at max speed (yes) which I believe it does. The next part of the check is air pressure switch proved? Am I checking the voltage across the switch? Is it worth me trying a new PCB? It's not doing anything but the yellow B LED 5...

Hi, Alpha CB28 had water diverted fitted two weeks ago. Red and yellow lights on yesterday indicated a non running fan. My plumber came out and pressed down on a relay on the board and the boiler kicked into life. Coming home, and it's not firing up. It now shows the usual yellow...

Hi, Sorry, yes I have a combi boiler. I occasionally have to top up the water in the combi by turning two valves (one clockwise and the other counter clockwise). Is one of these used to drain down the combi. I was hoping I don't need to do that. Cheers, Lee

Hi, I am putting a new kitchen in, and need to remove the kitchen sink, rout out the worktop and replace the sink. I have a hot and cold feed (obviously) neither of which have isolation valves. The internal stop cock for the cold water feed is the same area. Will switching off the stop...

Hi, I have a Mira 415 which is supplied by my Worcester boiler. I've recently purchases a new cartridge, but wondered what I need to switch off to stop the water peeing all over when I open up the control switch. Do I just need to switch off the mains water supply and then run the shower...

Thanks for all the replies again. I was not aware of Part P. I've chased the kitchen fitter, but had another thought, which may allow me to proceed. Could I not just leave the existing sockets and run extension cables to the required place? Is this an acceptable alternative, instead of...

Should also clarify, that the cabling is the original, red, black and earth I am using newer cabling for the extension pieces, ie. brown, blue and earth. I tried to put it all as the same in the original post to save any confusion, but ended up doing so anyway ! Cheers, Lee

Hi, Thanks for all the replies. I had intended to bury the choc blocks in the wall (I've only used these to join cabling together, where neccesary). Would I be best leaving these accessible? Are these considered to be a poor way to extend cabling? Is there a better way I should use? I...

Hi, I am having my kitchen fitted tomorrow, but have a couple of questions of some sockets I am moving aroung, extending etc:- EXTENSION OF EXISTING SOCKET? 1) I have an existing socket that needs to be moved along a little. This had two sets of cables going in to it. I have connected...

Is anyone able to help?

Hi, I do have a current problem and am about to replace the water diverting valve, but unsure if this second problem is related... I am finding that the boiler loses water, and I have to constantly have to top it up every couple of weeks. Can't see any leaks apart from the occasional...

Hi Ollski, Thanks for the reply. Mine is definately with brown trim and a Heatslave 9-24. Can I ask what the electronic part of the boiler is in reference too on the other boiler? Mine is a 9-24 RSF S. Do you know what the s signfies? Much appreciated. Cheers, Lee

Looking for some help with part numbers for the Water Diverting Valve Assembly. I'm getting a leak on this valve. Rang Worcester and they said they deleted all information on these boilers from their computers over three years ago, so no help there. The manual does not have a part number...
