Thanks, I have checked to see if there are any hairline cracks in the brassware. I have noticed the leak increases as the temperature rises. The leak appears to be coming from the centre from the copper pipe. The problem I think is because there is very little space to get as the connector. I...

Today suddenly the boilers CH Return Feed connector (the one of the far right when looking from the front of the boiler) started dripping and the pressure suddenly went low. I opened the brass coupling and found the washer had worn out, but it was of a very different type. It had a rubber...

Okay so the mains cable has been moulded!, once again so much for saving the planet! slogan that everyone including Dimplex is also drumming home. When a perfectly working appliance has to be thrown away because the mains cable can't be replaced! that is really bad? I will have to dig out...

I am trying to replace the mains cable on a Portable Dimplex Oilfilled radiator unit but I just can't figure out how to get to the bottom plastic section. The mains cable has got cut inside due to the bad design. I have tried removing the plastic cap using the screwdriver edge but no luck...

I think the plastic part broke almost immediately maybe it was not aligned properly and the very first time the water pressure was applied it snapped. In the original part this fitting is made of brass! therefore no chance of snapping and getting logded in the system...clearly the replacement...

Just to let everyone know, I finally managed to open up the boiler again...(lost count how many times I have opened it now! and bruised my hands and fingers.. I replaced the BES supplied DV with a proper original valve cost £180. I compared once again the replacement D/V with the original...

Thanks Stan! for putting my mind to rest. I will be replacing the newly fitted BES D/V with the proper one on Saturday. I will report back my findings. MG

I did contact BES to find out what the difference was between the 3 DV valves they supply which look similar but have different part numbers. They reply back indicating they are all the same it their operation, the difference was the fitting positions of the side inlets. I must also say...

The part that is broken is inside the inlet which connects to the pump 3/4 which is the front facing inlet when looking from the front with the microswitches at the back. I think in the original valve there is a brass ring which has a 3 point star like circlip which holds the spring inside...

Yes, Gasguru I couldn't agree more with you. I should have searched again for the genuine part instead of ordering the BES part knowing the previous valve I had ordered was £180. I thought the price must have come down over the last 6yrs. I will have to get back in touch with Ravensheat...

I today took out the valve to inspect what was going on and I found that the spring/plastic assembly which fitted to the front facing inlet has broken inside. I could earlier hear bits inside the boiler with the heating running now I know what was making this noise and I have a feeling this...

Yes ChrisR, I take your point that all the manufacturers do not make their own parts. I must admit I didn't find it any different to the original one but I am no longer an expert boiler engineer. I used to be one 15yrs ago. I had worked mainly on the Valiant combi boilers of those days. In...

Thanks Tony for your very detailed reply. Yes I couldn't agree more with you that the BES DV is definetly not the original product having noticed a difference in the operation of the valve compared to the previous valve. With reference to possible dirt in the boiler, I must mention...

I have had this Ravenheat 820/20 boiler for now 8yrs from the previous house owner. During this time I have replaced the Divert valve for the second time just 2 months ago. The first valve the diaphram was torn and couldn't find replacement back in 1999 so paide £180 for a new divert...

Thanks once again ChrisH, I will certainly look into it again as a part time study.
