Vokera Linea 28 - Cutting out

[sanj2000]

I have a Vokera Linea 28 (approx 8-9 years old) which is keeps cutting out. I have had a number of heating engineers out from my maintenance contract who have not been able to diagnose the problem which is an intermittent fault. Unfortunately they wont come out for this particular problem until it fully manifests into a total failure.
I have to continually reset the boiler to fire up the burners to get HW, this can last between 3hrs to 3 days before requiring a reset. Occasionally I get error code 01, but more often than not no error is displayed and i just get the temp reading. There are no problems with water pressure, or system pressure.

I have had the following replaced over the past 8-10 months
1. Main PCB
2. Ignition Module
3. Plate to plate heat exchanger
4. Diverter valve
5. Spark Plug Electrode

I've probably not explained it too well, so happy to answer questions to help resolve

Thanks in advance for all your help!

Unfortunately the insurance based firms do not offer very attractive employment packages and consequently do not get to employ the best diagnostic engineers.

So all they do is to change parts until hopefully they might find something at fault ( or not ).

There are still a couple of things they have not changed but it could well not be anyone of them and just an adjustment or setting!

I would suggest a proper boiler service
For this you will need someone who knows how your boilers works and often will be a repair person nd not a part changer

Boiler older than age you specify
