Machines in bathroom - rust issue?
I'm always a little surprised though with the way some continental countries seem to quite commonly put washing machines (and dryers) into quite small bathrooms, often in extremely close proximity to showers and baths.
It's illegal here due to both electrical and building regulations which are extremely conservative about electrical appliances and outlets in bathrooms. Installing a washing machine in a bathroom just isn't legally permitted at all. We can't even install light switches in bathrooms (other than ceiling-mounted versions, operated by a non-conductive pull cord). All bathroom light fittings have to be IP rated and any lighting or fixed devices like shaver sockets, fans, instantaneous electric showers, towel rails, heaters etc also have to be both IP rated and RCD (GFCI) protected and there's a whole load of tight regulation about earthing (grounding) that involves bonding of all metal surfaces and plumbing to the earthing system of the house to ensure equipotential zones i.e. that there's absolutely no possibility of a potential difference (voltage) between any metallic surface.
Electrical sockets (outlets) are can't be installed in bathrooms at all, with the only exception being a shaver shocker which only accepts 2-pin plugs found on shavers and toothbrushes and is limited to 0.2amps and connected via an isolating transformer to completely eliminate any shock risk.
I've just always wondered though when you consider that washing machines are not IP rated, beyond very very simple levels i.e. they don't have exposed electrical components and would generally not be suitable for installation in damp or steamy environments, do they not rust and cause problems e.g. if their electrical components or electronic boards become damp?
I wouldn't imagine that an open-winding electric motor, as found in most machines, would be too happy with constant exposure to steam. It would also apply to things like relays and certainly to the electromechanical controllers (cam programmers) that were used in older machines. Even modern electronic controls would probably have issues with damp conditions.
I appreciate that the machine's probably connected using a socket that's RCD protected, so the shock risk is extremely low, but it just seems like it would potentially shorten the life of any machine to have it in a steamy bathroom.
