Hi all.
Had this problem a bit ago.
The burner is definately not regulating on the DHW and i don't think it is on the central heating either (not so obvious due to the time it takes to get up to temp).
When the combi shower is running the water temp lights go to max and then the burner cuts out until the water cools then it fires up again. This goes on throughout resulting in a kind of dance when having a shower, wash when cold, rinse when warm
I get NO warning lights.
I changed the heat exchanger a few months back and all seemed well.
Since then we have had to have a new meter put outside and new 22mm pipe work to the boiler as our supply was low.
Could this have changed the gas pressure at the boiler, could wrong gas pressure cause this and would this then need resetting?
The manual points to the DHW temp sensor and it says to clean it. On parts arena this sensor is down as a special so i take it they don't stock them as they only need cleaning rather than replacing?
It also mentions the pcb but obviously, due to cost, this would be the last thing to change?
Any help much appreciated.
