Help
My Baxi 105e stopped working Saturday morning and the led was flashing on the fan symbol. I used the fault finding guide any the was no voltage to the fan from the PC board. Tested the fan with a separte supply and it worked. Made a decsion on changing the PC board which arrived yesterday the board is modified from the old baord but all the connectios fit . When i fired it up the Flame and safety thermostat led is flashing . Where do I go next?

On fitting the new pcb it will require reseting i have known this to take upto 20 seconds or so and a couple of attemts.

In fact there is usually an instruction in the box........

sometimes turning it to the reset position and back doesnt reset it so try turning it to the off position and back!

Yes gaz its weird that isnt it ?

Thank you no instruction with the panel how can i reset?

 

[fine tune]

it will be in the manual , its the switch on the far left turn it to the rad +tap symbel then turn it further against the sprig loaded pressure and hold for about 20 secs ,that should reset pcb . as said you may have to do this a few times before it sets
