Bentone B11 burner always locking out.

The posted problem is also a good example as to the fact that it is always a good idea to retain second hand burners from scrapped boilers as it can be far easier to swap a faulty burner (or parts from it) for a working second hand one to save messing about fault finding if you are very busy.

If it had been severe weather I would have swapped the burner. I have an old B11 burner would have done temp. I also have loads of electrical parts for them - better to have a second hand part than nothing.
Just an update on the boiler - no messages received, so the new EB1 transformer must have fixed it.

Just received a text from customer to thank me for sorting the boiler as it has been running fine with new transformer. Lesson is - don't assume a nice strong spark on several tests means a transformer won't fail intermittently.
Thanks for all the replies & help! :smile:

Glad you got it sorted.

Glad you got it sorted.

Thanks Simon, - your first reply was spot on. You were lucky though! :smile: Let's call it an educated guess!
I did everything right, except i probably should have waited an hour at least, but just didn't find anything wrong.
Had one yesterday on a friends boiler - another EB1 but no spark & the back of transformer had a large blister. Seem to get a run of same things.

...EB1 but no spark & the back of transformer had a large blister......

Did you change the control box too? Often this is caused by the box....cause and effect etc

On my friends boiler, I didnt replace the Satronic control box & that is a very good point!
He is an Electrician & had already diagnosed the fault himself & I let him get on with it himself.
I know that is a common thing on the Satronic boxes to do.
