Vokera linea 28 code 3

Stop wasting money fiddling. get a gassafe engineer who knows Vokera to look at it.

 

You should have said!

I would still suspect the venturii - blast them thru with compressed air. They are the usual culprits on these.

 

check flue is not blocked with spiders etc, or ventura

 

Hi,

Di you ever get a positive fix for your problem?

I have a Linea 28 intermittently displaying code 03 and have done the following:
Fan replaced, pressure drop switch replaced, both display and main pcb replaced, ignition box replaced and flue venturi cleaned.  (flue venturi cleaning was the first action by the way).  Problem still persists, although it often goes through a complete heating cycle with no problems.

 

Double check the APS, if no joy, it's a short in the wiring harness.

 

been there with these boilers in the end Vokera fixed it but i never found out what it was although the owner told me it took two visits and a few parts. i stay clear if it is not venturi tubes or aps. Nightmare boilers.
Fitted the new compact A for a bloke the other week what a pile of rubbish that is as well.

 

Have you put a monometer on the fan tubes Dunc, what readings are you getting? 

 

Yes, a local heating engineer checked the pressure drop and measured it at 4 millibar.  Vokera tech say minimum is 3 and the switch operates at 1.  Think I've got a faulty APS despite it being a new component.
