Potterton Main 24 HE Boiler Power Light Flashing

Royster74

The thread started before I had any idea what was wrong. Then I replied when I had some more info. Like I said it was a long shot that someone was able to say "Yep seen that, what you need to do is...."

Then when I had some more info it would be helpful for anyone else in the future who has the same fault. I'm sorry if you feel like there is a problem with this thread and as is said nowt stranger. And I'm happy to have it locked if that's what is deemed appropriate. As we can see this error is not often seen with my type of boiler. If still unlocked as soon as I have it fixed I will update here what fixed it..

Sorted!

3 things:

APS microswitch sticking. (new APS) Small split in APS hose (trimmed hose) and loose connection on PCB (removed, cleaned, Con checked and refitted) . the flashing power light was a result of the above 3 things apparently. Happy that I've got it sorted and found that an undocumented error has been solved

:cool: Glad you got it sorted :T

Just a couple of things though: -

Yes it is quite feasible the APS was sticky and as blowing it might have been at a higher pressure than is needed for it to sense, it would have operated!
However, a loose connection may just have given the same fault, as the APS would NOT have been sensed by the PCB as working?
As would a split APS hose have NOT necessarily allowed the APS to sense the correct pressure?

Which still raises the question WAS IT THE APS AT ALL, and have you paid for parts and labour that where actually not needed in the 1st place

The correct diagnostic skills by use of a multimeter to test circuitry is always advisable?
