We're moving house soon and I'm trying to work out how to prepare some of the appliances. Washing machine is fairly straightforward as it'll be plumbed in straight away at new house. But dishwasher is going to be stored in garage over winter for several months so I probably need to drain water out of it etc? Is this feasible? There does seem to be a drain cycle in the instructions. Any tips for protecting it from ice or mould?
