POTTERTON ENVOY F CODE / NOT IGINITING THOUGHTS PLEASE

[neilyp]

I serviced a friends Potterton Envoy about a month ago and he is now reporting that it keeps locking out "F" code.
Im due to go back to take a look but could do with a few opinions as im new to Gas work. (First year)
The main suggestion i have had so far is check that the igniter is not wet. The first complaint was that it did not come on first thing in the morning, then after a restart it worked. However now im led to believe it is more often, which i think is coinciding with the bad rain fall.
My thoughts are that it is rain coming in through the flue however i would appreciate advise if anyone has any.

Regards Neil

The normal fault for this code is the the hot surface ignitor is dead. CORGI job I reckon

 

[neilyp]

I am corgi registered so fitting is no problem, would this fault be intermitent if the igniter was dead?
Is there a possibilty the igniter could be on its last legs or is this unlikely

 

[corgiman]

Must say that I have not seen that is gone and comes back on again

if your are an RGI why dont you post this in the combustion chamber forum?

during ignition can you see a glow in the sight glass?

as for water going down the flue during the rain, well its a condensing boiler and has water going down the flue all the time so that wont kill it

could be a block condensate trap, when this happens on these heaps it floods around the fan

I wasnt aware of the combustion chamber forum is it part of this forum or another site?

I am going to check 2moro although during the service everything seemed ok. (ignition ok etc..)

I really just needed some starting points so thanks again.

BEware these are sodss

What do you mean "these are sods?" Do you mean the Envoy? I have a few BG friends who i did my training with they also said these are a nightmare.

It makes no difference if trap blocks as all the condensate leaks fropm the poxy seals !

So what are your thoughts on my original post?

If you are going to touch one of these you need to get every seal, you will need it.

Awful things

Am i missing something here CM or are you taking the rise.

I may be wrong here but doesnt condensate only go down one section of the flue? Which leads to the condensate trap. The other leads directly to the combustion chamber.

Is this right?

Oh yes that happens everytime mate.. NOT lmao

I cannot tell you how many fans I have had to replace on these due to flooded chambers

Not at all i am refering to the combustion chamber forum thing scat

no not really

condesation will occur in the flue and will lead to the sump, so rain water will too go to the sump etc
