intermittent fault

[micpwelsh]

I have a baxi 105e that turns itself off (all power , led's , fan and pump ) just after its heated up and the flame turns off. i've seen this happen maybe 5 times in 3 month (but it must be happening more just im not there all the time lol ) . The odd thing is after 3 seconds it resets itself and works again like normal , any suggestions ?

How about a loose connection in the supply to the boiler

thats what i checked first it was tight a good conection , but thanks for ur help

I would also think loose connection, for the mains led not to come on

 

[micpwelsh]

if that was the case wouldnt it happen more frequently ?

When you say "it" which connections and where, did you check L&N in the boiler, L&N in and out at the Spur, L&N at the supply to the spur (this maybe a dedicated supply from the CU or may even be a joint box or a nearby socket.

Ive checked every connection into the boiler itself, even the plug
