Dishwashers - intermittently faulty (Elm Grove BN2)

Two tabletop dishwashers which both have intermittent faults. The cookology one occasionally starts to trip the fuse, and the airmsen one throws an E3 error. Both seem to stop throwing the errors if they're drained and unplugged for a few days.
Free to a good home if someone can tolerate the intermittent errors or thinks they'd be able to fix them up/use them for parts.
Collection from Elm Grove area before Sunday - I will take them to the dump then.
