Vokera Linea 28 boiler

[davebgas]

They start going on at me (especially the non technical managers) and i'm off...... will go back offshore if I have to

first thing you would check if you are getting an 03 vokera fault code is, is the fan running! from your original post you said he changed the fan,nothing happened,so he changes the pcb as the fan was not getting any power!!! when they return ask engineer to clean venturi,replace silicon tubes going to air pressure switch (aps) fan is brand new pcb is brand new check and set gas pressures and check all flue connections are tight and gaskets are intact. best of luck

Yep exactly what happened. Took them 5 days with a catalogue of errors and engineer not turning up to get to that stage. That's why the Regional Service Manager was involved.

What I am wondering is if the fan/flue problem burned out the circuit board? I keep getting told that these error codes don't always give them the true error! What exactly is the point of an error code if it just gives any old error it feels like!

when they return ask engineer to clean venturi,replace silicon tubes going to air pressure switch (aps) fan is brand new pcb is brand new check and set gas pressures and check all flue connections are tight and gaskets are intact. best of luck

Thanks for all these suggestions. I shall have a list ready for when he turns up.

What is/are venturi by the way?

Pay for me to come to bonny scotland

I would love to but I'm already paying you £18pm.

Venturis are devices that constrict the flow of air through a restriction in a pipe.... causing a diferential pressure either side of the 'throat'. This air pressure difference is caused by the fan blowing and is transmitted to the air pressure switch to make/break contact.

If the venturi becomes slightly blocked the differential pressure - which is already very small - can cause the APS to 'drop out' - hence shutting off the boiler.

thats the basic usage, I can elaborate onto orifice plates and commercial venturi applications if you want

explain that to my dense colleague

the venturi is situated at the fan, two silicon tubes go from there to the aps. this tells the aps that the fan is running by creating a differential pressure(the air pressure switch clicks on/clicks off). if BG tell you they will have to order parts and it may take days, Heatspares in Helen St, Govan will have them on the shelf, and BG use them all the time. best of luck again

sorry davebgas beat me to it

Basic usage is just fine thanks. Don't confuse me any further.

explain that to my dense colleague

I shall assume he is not dense first of all - I do like to give people the benefit of the doubt.

I always do things too fast,.... well so our lass says

They always tell me they have to order a part and usually they can't order that day either because it's a holiday or it's after 6pm.

The boiler is at least working just now as it is resetting. However I'm fed up with the uncertainty of not knowing whether I will wake up to no heating and no hot water.

Does nobody carry parts these days?

 

[davebgas]

Every patch has different 'high call' appliances and engineers carry common parts for them.... you just have to think how many different boilers/systems there are and how many parts are available and its just not realistic to be able to carry every part, frustrating I know.... mind, it takes nothing to clean a venturi....

 

[glasgowgas]

as far as i know BG boys use their super computer, which contains manufacturers manuals, BG hints and tips sheets, step by step guides to boiler repairs, and this is where they order their parts, on the computer, parts then delivered to their nearest post office or parcel depot!!!!!

give the BG repair boys a wee chance to fix your boiler but you at least have the info to challenge them on their lack of repair skills!!

best of luck

Last time I looked in the 'little blue book of boilers,2005 edition,there were over 1100 boiler listed with some manufacturers having nearly 100 models.

Impossible to carry spares for one boiler never mind 1100.

Only thing I carrry is Honeywell thermocouples everything else I have to buy on the day. Some customers can't even tell you the name of a boiler by manufacturer on the phone never mind the exact model.

'Ehr,it's a big white wan',lol.

Very frustrating for all concerned.

Engineer has been. He looked through the the job logs and confirmed that fan and pcb have been replaced. Venturi and tubes were cleaned on last visit and soft-light adjusted.

I asked about aps - he said it wasn't normally an intermittent fault on this. It usually worked or it didn't.

He said he really didn't know what to do next as everything had been done already. He said that the tsm is normally brought in next although noted that he had been on last visit. If the tsm didn't know what to do next it was normal for the manufacturers to be brought out to see what they can do.

Of course he is only an engineer from another area as today is a holiday. Another visit has been booked in for tomorrow afternoon with tsm to come too. If tsm can't make tomorrow someone would phone and rearrange.

We shall see what happens next.

Tonyboy, if thermocouple is the only component you carry in your van, you must be on the road a lot just sourcing and picking up parts.

I can usually carry out service and repairs on boilers with many often needed parts and components stocked in the van. I have three compartmented boxes (two of them with items for Vokeras), and three carry cases (one that goes with me to all Vokera households) and much more to allow first call repair. Do agree it is impossible to carry every part for every boiler. But then again one gets to know what make and model of boiler is common in an area and what parts are needed more often then not.

I hate sitting in traffic. Sometimes I have to push myself to go south through Clyde tunnel for parts and spares.

WRT Linea boiler. The fan will not run if flow switch not operated. Venturi fault would only occur AFTER fan is running. I thought the fault was present on the boiler. If that is correct surely excellent flowchart back of manual would have assisted fault location and successful repair.
