fusebox is actually not box at all it is inside metal box within wall. The fuses are held by one bar, there is dark brown protective cover around fuses held by 2 screws. on the right side is main switch for incoming supply. all N cables are connected in one corner and all Live are from...

Thanks for reply I am in UK. I was told that since other circuit does not have earth it will not pass inspection and if he does any work he would not do it unless he gets earth to each light point and switch!? I have metal back box behind switch but it does appear it is not connected...

Advice needed. Let me first say I have no intention of repairing this myself but need expert and independent advice. Due to water leak from flat above water got inside cable conduit inside the wall on the run from ceiling down to switch. Existing cable is very old and did not take...

if you could identify source of interference then it's easy to find solution. you need to turn things off/on to identify culprit, if in your house. It's likely to be device always plugged on. Another problem you may have is that your units are to far apart, or there is to much clutter...

Hi, Radio interference sources are huge in numbers from malfunctionig power supply unit on PC (one of the worst) to all other similar device. Any electrical component may, under some circumstance, create radio interference, hence us radio engineers make living designing protection systems...

hi, sorry my mistake it should read: speed of light (km)/ fequency HZ so 300,000 Km / 418 000 = .718 m or 71cm so your antenna would be 1/2 or 1/4 of this figure. some antenna can be using the entire wavelenght or in this case .718 m It's been while since I had to do...

Hi Antennas are one thing I know about... If you simply add piece of wire to your existing antenna you may actually reduce it's performance. This is because each antenna has to oscillate at correct frequency in order to transmit or receive the radio wave, the correct...

Have now confirmed following: If I follow fault finding diagram, gets to end without fault, as boiler fires up. Red led on main board operates etc. I have also measured resistance of temperature sensors and they are under 15K so I assume within expected value. After some time on CH...

Thanks ChrisR, There are two pipes going up from diverter valve , one is 22mm and is at the back end of valve and goes up and to the right side of boiler, it follows the pipe where the pump is on. Another pipe going up is 15mm and goes up from the front of diverter valve and bends to the...

Can I test this before I get CORGI man out to replace the overheat termostat, this is third failure with boiler in less than 3 weeks !!! I may skip the lot!

Thanks, I presume you mean two 22m pipes for CH flow with valves just below boiler casing then these two do get worm as the boiler is turned on. The boiler works for 30 minutes and radiators do get hot.

how could I check if Puma diverter valve failed? would this result in pilot going off thanks for advice

I have had no end of problems with my Puma 80 recently. First water pump failed, and I replaced the head. Boiler was fine for more than a week after but then fan failed. After the fan was replaced, I decided to add some sludge cleaning chemicals as during pump change week earlier I have noticed...

HI, I should have used word replace rather than repare for pump, sorry if this created confusion. You should be able to hear fan running slow once the boiler is on, if you follow fault finding diagram this should help. I have same problem at the moment but to replace fan is apparently...

Hi I had just fixed my Puma 80, it had also failed pump. see my post discussion for some usefull info. I also would like to find out if Puma 80 can last for more than 8 years as I have one. My one has worked fine, it had board changed when nearly new within waranty, and fan went 3 years...

Thanks for help. I have found replacement pump, in fact I only got the head IDEAL and it has 4 screws with seal to fit old Myson pump case/body. I have also discovered that old pump body is well corroded inside so that small channel where ring seal is held has gone in places. It did seal...

I have puma 80, failed this week. I have followed fault finding chart and concluded that pump failed as it did not operate after boiler fired up. After short time boiler shut itself down probably overheat protection and pilot went out. I went to local merchant he sold me DAB VA 55 pump, my first...
