Thanks Tony. Well, Vaillant didn't want to keep replacing parts at their expense and I wasn't there when the chap came up with his last diagnosis. We did immediately call out our home emergency insurance and the heating engineer turned up this evening. He wasn't keen on messing about with the...

Continuing from the thread "Ignition failure at peak times" (now closed?) : The home insurance is proving frustrating, however Vaillant as well. Home insurance sent someone over last week (as mentioned in previous thread) but when followed up regarding when they would swap electrodes out the...

Brief update: home emergency (insurance) sent a chap over who thinks its electrodes that need changing. As they came round on a Friday they ordered parts and said they'd be round "next week". We'd cancelled the Vaillant callout but am wondering whether they'd have been able to do the repairs on...

Valid point. When the chap was round the fault was on. When starting up the boiler the scary internal explosions were heard but after a few attempts got it started up. As it's a combi and I have no gas hobs he just let hot water run and measured pressure going into the box at the front of the...

Very useful tip, thanks! Grid engineer tested pressure to property as 20mb, but that's all they'll test when called out by National Grid. My gas box has two feeds from it (an old one that now only feeds the oven and new one that routes around the outside of the house to the combi). We'll see...

Thanks. Sounds like you have experience with the diagnosis. Is there a reasonable explanation as to why the fault has not been occurring during the day but only in the evening & overnight?

Had mains tested by National Grid callout. Engineer saw the fault but was happy that gas pressure to property is ok, so must be something else... Waiting to see if the HomeServe chaps come tomorrow to investigate boiler + pipework.

Thanks again, Mick. Good advice. Shame there's no easy way (for me) to measure the pressure. I would love to be able to just take readings and record them over time to use as proof there is a problem at my property (assuming that's the issue, which it may not be).

Mick, thanks for the quick response. It is a very frustrating situation. We don't use the same person that installed the system to service it so we're ok there. It has been fine the entire 3 years we've had it (service due in a few weeks). We don't have gas hobs, but do have gas grill and oven...

Have a Vaillant Ecotec 831, less than 3 years old, serviced annually, with magnatec filter. In last week boiler fails to ignite (ignition failure) , code 28, but mainly between 6pm and 8am ?? It "explodes" inside and then fails. Behaves normally during the day. Gas work was done on our stree at...
