BLOWING FUSES !!!!!!!

So did you have anybody look at it or do anything to repair it or did you just leave it to dry out and assume it would be okay?

yes

The you, or someone with the ability, needs to trace the fault. Otherwise youre wasting your time replacing one item after another at random.

I'd start by putting the original controller back in, at least everythings wired up right then.

A thought, is it a mixer tap that he attached it to? Did he turn on both the hot and cold taps together? If so then you may well have fed high pressure cold back up the hot pipe and caused the header tank to over flow.

As for the electrical problem, I'm sure others know much more than I but: If the units, old and new look identical, have the same model number? I wonder if there are internal links for setting different wiring plans? Could you post the model of controller??

Very best of luck with it all.

The brass shafts from old potentiometers make great replacements for 13A fuses, never had one blow yet!

P.S. DON'T DO IT!!!!!!!!!!!!!!!!!!!!!!

You must be old - I was buying them with plastic shafts in the 70's. The only time I got to see metal ones was in scrap equipment donated to me!

......wonder what current they take to blow.

That's the best theory yet! I couldn't see the connection between pressure washing and flooding the airing cupboard - but that would explain it.

What a plonker! [OP's husband, not you!]

From my experience of pressure washers, they have a good flow, and rapid cutoff when flow stops causing water hammer. If ther were any push fit fittings or loose compression fittings the repeated hammerring may have pushed them apart,

Most I've seen (quite a few) have been either steel or aluminium if they weren't plastic.

You may jest - but I've seen it done - without any ill effects , as it happens.

The workshop in the place where I worked in the 60's was 'modernised' by replacing all the 15A outlets with 13A outlets, and the plugs were changed on all the kit. A MIG welder which had worked perfectly well with an unfused

As far as I can recall, the wiring wasn't changed - they were radial circuits, fused at the MCB, so using a solid 'fuse' in the plug wasn't really a big issue - but isn't to be recommended for general use!
