Vokera Linea 30 HE Not Rectifying?

[arran197]

Had to look at this today.

Fault code 10 (flame not detected).

Boiler was actually firing up, but not rectifying. Checked the leads all had continuity through them. Took the flame electrode out and it looked pretty bad. Cleaned it up, popped it back and it them fired up. I've ordered a new one, but is there any common problems on these that could cause this?

19.5 mbar on ignition, gas valve breather tube clear.

Also, I couldn't get it to go in to max service mode, despite following the M.I.s. Any ideas?

All what you have done, plus ensure condensate is clear, then new probe, if that dont cure it its PCB, it fails and goes into a cycle of firing and stoping then restarting, when demand is created......they were on version 12 last time i changed one, you need maual as board comes blank and you have to load parameters, gas,NG,LPG, KW rating which sets LL MM HH fan speeds, think they are now red also not green

This had a red board fitted and a green ignition board. There was no letters at all, so I'm wondering if a new board has been fitted and not set up correctly then?

Possibly pal, may explain why it wont go into service mode, you load password? off top of my head 53? but is on drop down flap

No idea what the password is tbh! I was just trying to get it in to service function for flipping ages! I probably won't be going back to fit the part due to being on holiday next from Thursday, which is a shame, but I want to know if I come across it in the future.

Yeah you have to input numbers to activate service levels pal, as it can screw the boiler big time.....

Went back today and fitted the electrode. I wasn't expecting the difference in length to be quite as bad as it was. The old electrode was about 25mm shorter than the new one! Anyway, ran boiler up 10 times and it stayed on every time.

Nice one pal, if it faults within next week deffo PCB required after probe

I'll be in Turkey, so hopefully it won't go off again. I'm surprised I went back to the job tbh, I don't usually work on that housing association contract, I was just helping out. So someone else will be going back I'd imagine, if it does go down again. Which no doubt, being a Vokera, won't be too long! Lol!
