I'll have to call up Vaillant tomorrow to ask why it only says 1 year guarantee. The thing I can't work out is why you would think the main heat exchanger is blocked and not the secondary DHW one. I mean the radiators are heating fine to correct temp and there is no noise when the heating is on...

Yikes. This doesn't look good for me then. My old boiler was working fine and they knocked on my door and convinced me to have it replaced with a much more reliable modern boiler. Repacing the main heat exchanger will cost a good few hundred quid I would imagine. It's just unfortunate that this...

1 year waranty is all it says on the warranty card. I thought that the 1 year manufacturer warranty is all you get. Is it supposed to be longer than that? The boiler was replaced under the government boiler replacement scheme in December 2014 (15 months ago) by one of the agencies that were...

It only had the basic 1 year Vaillant warranty which ran out a few months ago. I was hoping it would be something simple like an NTC thermistor for the DHW but I don't think that would cause it to make a groaning sound even if was faulty. Would a blocked heat exchanger cause the groaning sound...

Hi, We had a new Vaillant Ecotec Pro 28 combi booiiler fitted about 15 months ago. It worked perfectly until a couple of weeks ago. Two weeks ago the water temperature seemed to be getting lower. Turning the comfort mode on or off doesn't effect the overall temperature out of the tap. It...

Hi Chris, I'm too old to know what iirc stands for but the boiler is definitely a 1e version. You may be thinking of the vuw 242eh which is slightly different. Anyway, it's sorted now! :D

Not all RGIs will admit to a wrong diagnosis. In my experience some will say that there was another faulty part in addition to the one that they had (wrongly) replaced. Hence increasing cost to the customer. It is difficult for a customer to prove that a certain part was not actually required...

UPDATE: One of the members of the forum kindly emailed a manual for this boiler. After a quick read through I managed to find the reset button for the overheat thermostat. I pressed it and the boiler seems to be working fine now. For anyone else in this situation, the reset button is in...

Thanks Ian. That was exactly what I had been looking for. :D

Hi, I've just PM'd you with my email address. Many thanks.

Thanks Dan. I'm just a retired mechanical engineer and not an RGI so I don't qualify to get into the combustion chamber. :wink:

Hi, I've been looking all over the internet but can't get a service manual for this boiler. I've managed to find one for the VUW 242E but nothing for the VUW 242/1e. I have noticed that some parts |(like the main gas solenoid) are different on the two boilers. I'd really appreciate it if...

Thanks Tony. The reason I don't want to go BG straight away is because I have a spare similar complete boiler lying around in the shed that I can get parts off one by one and see if i can get it going. To save time and hassle do you have any idea which parts I should try first? I have ruled...

Thanks for the reply. I've checked all the obvious but couldn't work it out. Well the magneto doesn't seem to cost that much but a main board could be pricey. I have just noticed there is a slight leak from the flow switch (DPS). Could that be the culprit?

Hi, My old bolier a VUW 242 Turbomax 1/e has stopped firing today. Just checking to see if anyone has any ideas on it as most people are not that familiar with these older boilers any more. Any help/ideas/suggestions will be highly appreciated. When I switch on the bolier, the green power on...

Well, a guy on ebay was selling both a pump and heat exchanger for £60 (both brand new in box). I bought both and had both parts replaced at the same time. The boiler has worker perfectly ever since but as both parts were changed at the same time I can't say for sure whether it was the pump or...

It's a vaillant Turbomax Vuw 242 1/e. Could the hot flow pipe possibly be caused by a weak/faulty pump causing the poor flow that results in the hot water being dispersed to the heating?

Thanks mate. I've been looking for those for over a year and have just bought them using the ebay link that you posted.

[b] Thanks Bunnyman for the advice, I will definitely be taking heed. As for what you said Tony, anyone can change one part after another and expect to eventually get the problem sorted after finally getting to the cause. I definitely don't think these old boilers are simple but I would...

Anyone?
