Simply Build It

Well a microswitch is electrical - so no water there - it may be from the diverter valve around the fulcrum arm - which operates the microswitch - you can a buy a diverter overhaul kits for a few quid - so yeah it is worth repairing as very cheap. Unless he was thinking of repairing the whole diverter - but even then you're only looking at £120ish - if the boiler is in good condition it would still be worth the repair.
