vokera error code 01

[albysenior]

guys
sorry to be asking questions on my first post but promise i'll pay back with any advise i can give on cars, (motor tech for over 25 years last 10 on vw's)

so here goes

vokera linea plus ag
shows 01 code when the heating is on and then you call for hot water.

heating on its own is 99% ok
dhw on its own is 99% ok

what i'd like to know is what happens thats different when both are on.

had the boiler a while now and only probs i've had is i replaced the thermister a long while back and got the main pcb refurbed a while back
but apart from that its being a great boiler

many thanks in advance

Most common fault is the ignition PCB. Either located on the gas valve or the updated one near the main PCB. It could also be electrodes, gas valve, gas pressures etc. You need to call someone out i'm afraid.

does anyone know how to check the flame sensor, and is it an actual flame sensor or just a temp sensor ?
