It would appear so, though I have no idea how to get it out. I have bled all the vents while the pump is circulating and no air is coming out of any vent or rad... I even bled a bucket full of water from one rad through the bled valve while the pump was circulating to see if this would move...

Yes. I turned the stat up on the boiler to 5 and it fired. Though there should be no reason why I had to do this ?

Hi, I have a Ideal Mexico Super 2 on a gravity feed system. I drained down the system to change 2 radiators. Filled the system back up, bleed everything including the pump and vent valve next to the boiler. The boiler stat is on 3.5, but will not fire up when heat is called from the room...

Thanks for the fibe washer info. I will sort that out. It is an 84ET, sorry about that. The diagnostic flow chart suggests that I replace the potentiometer and not the O/H stat as you suggest - I only say this because the boiler did not trip. Would you still stick with the O/H stat or...

The CH had been on a hour or so yesterday evening when I decided to run a bath. After getting out of the bath later I notiched that there was water around the bottom of the boiler (housed in another room) The boiler appears to have overheated. When I tried to pressurise the boiler back to...

My wife brought a light that comes with a 3amp plug. I want to place this on the wall where there is an existing wall light is. Would it be okay for me to fit a 3amp box where the 16 amp 240 mains is and then wire the light into that 3amp box? This would seem fine to me but if there is...

You are right it does have a red flash beacon. All off our bills are actual since we changed to a new supplier about 4 months . The red flash speeds up and down for no reason, I noticed this when we tested the lights. I have asked the supplier to fit a check meter to check and see if...

Hi, I have just had a new digital electric meter fitted and my electric consumption has doubled. We are apparently using 22 units a day the electric company has said which they say seems high for our standard 3 bedroom house. On our previous bills it worked out 13 - 15 units a day. Also...

I will change both sensors and see how we go. Anyone any idea about the water pressure - could this be the water pressure switch?? Thanks to everyone so far.

No, the CH does not work at all. Just turns off like the HW.

Would be the CH sensor even when I switch the boiler to HW only??

When I turn on the hot water, the boiler fires up and stays lit for about 7-8 seconds then just goes off then with the water still running it fires back up after about 30 seconds and then stays lit for about 12 seconds and then goes out again, it contunes to do this staying around 12 - 15...

Fitted new ravenheat diverter value and that has cured the problem - also came with a new micro-switch which I did not expect. One thing though, when you turn the hw tap 3/4 open it will run cold whereas if you turn it half way it run lovely and hot????

Hi Bobbo is the diveter for a ravenheat 84e? The old diaphram what cracked and had little splits. The system pressure was held at 1.5 bar - should I need to look at cold feed pressure into the valve?? also the regulator screw is fully open on the valve and I have not adjusted this...

This is what happened when I replaced the diverter. Took the value off. Opened the top of the value and detailed how the diaphram mechanism went together. Cleaned out the valve with clean water. Replaced the diaphram and the push rod. Put it all back together an connected it back to the...

I now have no heating as well. Could I change the diaphragm or do I nee to change the whole diverter. I am doing this tomorrow. Thanks

its a Ravenheat rfs84e

I will advise of the make and model this evening. Why would the hot water only be warm if the heatings on though? residual heat??

I have a combi boiler which is a couple of years old. My heating works fine but when I turn the hot water on it starts of warm and then runs cold. The only way I can get round this is by having my heating on 24x7 to ensure I have hot water when I need it... I thought it might have been...

Not sure of the Z's at the board until tomorrow. Will the C10 be enough to cope will the intial 28A draw ??
