MY FERROLI BOILER IS SHOWING FAULT CODE NO CN WHAT DOES IT MEAN?

All you need to do is switch your boiler off from the mains , then in the lower left corner give it a good punch 5-10 times , turn it back on at the mains and give it a moment ..... YAY YOUR BOILER IS AS GOOD AS NEW !!

A plumber's tip which is sure to work - switch your boiler off from the mains and bang on the lower left hand side of the boiler 5 - 10 times. Switch the power back on and hey presto - your boiler will be working again!

I had the same NO CN error message and found this advice on another site. (It's something to do with the alignment of the PCB board and a little knock is all it needs to get back into place). It worked for me so I thought I'd pass the advice on! Good luck everyone!
