You're more than welcome. As Tony has stated there are ways around re-occuring problems with hard water. It is definately possible for the heat exchanger to be blocked again within the time stated, particularly if the cause of the problem isnt rectified. Its not a heatexchanger issue but the...

I think you should take advice that you are being given. I am not trying to cause a confrontation. Im just advising that you should seek advice from a local engineer that will be able to solve the problem for you almost immediately. if you try and fix the problem yourself you could cause many...

Your more than welcome. I hope it helps. As stated by Agile, please ensure that you get someone thats fully qualified and understands the concept of what i have mentioned. It may be worth showing my answer to your engineer for guidance. If he/she refers to the Manual he/she should be able to...

isolate the heating flow and return overnight and see if there is still a pressure loss.... if not then the issue is on the system not within the appliance. there are only limited places you can have pressure loss within the boiler and it looks like you have covered most of them. Plus, if...

If you have a Hxi then the problem is not with the boiler. It is with the controls for the hot water/heating. The appliance is a heat only boiler so doesnt know the difference between the 2. It receives a switched live and fires. the controls and valves then determine where the heat is sent too...

Hi There, This loud humming noise sometimes described as "trumpeting" (sound of a horn/trumpet) is often caused by the CO2% readings being out of calibration. I would suggest getting a gas safe engineer into the property with an analyser to measure the readings that the appliance is...

F14 on these appliances is that the central heating flow thermistor is reading a temperature above 95 degrees. If its only happening on hot water then its not the thermistor as it would happen in heating too if that were the problem. The only difference between the hot water and heating circuit...

You shouldnt be inside the boiler if your not a gas safe engineer. Have you considered that it might not be the braided hose? it could be that the expansion vessel is flat or that it balloon inside has failed. It could be the hose but there are other posibilities. Before you cause yourself...

Exactly. Technical lines should be used when genuine help is needed. Far too many people pull up at a job... ring the technical line whilst they are sat in the van and expect the person on the end of the phone to do all the hard work. These people know who they are and should be ashamed of...

This made me chuckle... If there werent as many engineers out there that didnt know what they were doing then technical lines wouldnt be needed. Iv visited some manufacturers and sat with their technical line and the calls are unbelieveable! "the boiler isnt firing with demand"...

Flow sensor in these isnt it? simple check to prove. turn heating on and you get temperature on the display. then turn a tap on and it should show pressure. (leave heating on whilst you do this as HW is a priority) if it doesnt change to pressure you could have a sensor problem (old friend...

Wouldnt quite describe this as a "common fault" with the boiler. The boiler is only as good as the quality of the water and system it is on. Not the heatexchangers fault if its scaled. op. Are you getting any fault codes? I wouldnt say divertor because if that was an issue you would have...

Anyone had dealings with Glow-Worm...?

My cousin living down my street having problems with boilers. these problems is many times a day. the boilers is making many noise in night and in day it is make the slushing noises. sounding like me hot water maker kettle. it is only having problem when hot. can someone please point...
