Hi all

I have a vaillant boiler 282 model

It has worked well for many years but recently I have had a new expansion vessel (external) and water pump fitted.

The boiler is working much better for the above but is still locking out every few days, usually when starting first thing in the morning having been off all night.

I managed to take a video of when it locks out a few days ago which you can see here:-

Do you have any ideas as to what extra work I should have done to cure this lock out problem :?:

I would be most grateful for your thoughts on this and thankyou in anticipation of your help.

Thanks :)

no it does not seem to do this

before it locks out the flames appear and all seems well but after about 10 seconds from the flames starting the boiler locks out and the flames cease

does this help :?:
 
Can you exactly measure the time? Not just onece but several times and see if its consistent.

It may well be a flame failure lockout and that will usually need diagnosis by a competent boiler engineer.

hi the only other idear i have is lack of water flow though the boiler, and its going off on high temp. you would be best getting a vaillant engneer out, it costs, but they will fix it there and then. wellington
