I have a Halstead Eden VBX30.
Last week, the RCD tripped in the fuse box. I traced it to the central heating circuit, and finally to the boiler, causing the fault.
As I removed one of the case screws on the underside, a stream of water started coming out.
(This is the second time this has happened in the life of this boiler - the first time, I cannot remember what caused me to investigate, but the base of the boiler had filled up with water due to a split in the condensing pipe. Back then, the fuse box was the old type with rewireable fuses; no rcd. The pipe was repaired, and the boiler carried on functioning correctly.)
Anyway, once I got the cover off, it was plain to see that the base had again filled with water, and once it had reached the mains terminations on the pcb, it had caused the RCD to trip.
Although suspecting the condensing pipe again, it is not obvious where the split is.
The base of the boiler was dried out, but the boiler will no longer start in order to find out where the water is coming from. (There is no static water leak).
It is failing with a code 7 meaning no fan/no flame.
On start up, I can hear the fan running, backed up by 240v on the fan output on the pcb.
I have taken the pcb out, and it is clean with no water marks. The mains connections are slightly lower and so the water would not have reached the pcb itself.
Other than blindly swapping the pcb over, what else can be checked? The fuse on the pcb has been checked and is OK.
