Potterton Combi 80 no hot water no heat

[nick.c]

Hello hope someone can help me out with this very perplexing problem.
I have a potterton combi 80 about 6 years old at the moment have no HW or CH I have followed the fault finding chart which indicates that the frost stat needed replacing have done this but still no joy.
This is what is happening- When calling for hot water the led light on the board inside comes on the fan runs pump spins but no ignition or any form of spark.
When turn central heating on no led light fan does not come on pump does not run bo spark or flame.
I have checked that the pipes to the air pressure switch are clear.
It might help if I could track down a copy of the user manual but have had no luck finding on ptterton website where else could I look?

Any suggestions ?

Thanks
Nick

I would be seeing if the APS is actually operating before going on to the next thing to check.

Having said that the APS rarely gives any problem on that model. I dont think I have even encountered a fault in that area.

Check the fan, sometimes they stiffen up
Ignition a.k.a. sequence pcb's go quite often on these ,
sometimes I come across sensitive overheat stat.


BTW boiler is same as a Potterton Puma
