Discuss water ingress ryefield boards in the UK Electrical Forum area at ElectriciansForums.net
DW, I’ve yet to have a board I couldn’t repair. Even arcing across insulators is fixable by gouging out the carbon track and then varnishing or building up with epoxy. Sometimes I’ve resorted to making insulators.
The OP needs to test and localise the fault, then closely inspect and repair if he’s capable.
“Change the board” would be a last resort. Lead time for a spare precludes that.
If I repair something I'll put my name on it.
