Not many will have the dishwasher installed. It was my trade off against the underwater lights which Luuke insisted on having. We are glad we have it though. We use it a lot, especially when we are in a marina attached to shore power.
Modern dishwashers check if there is left over water in the dishwasher when you switch it on. The movement of the boat can confuse the software sometimes. When this happens, there is a red light that remains on and that is all that happens. The only solution is to remove the dishwasher from the cupboard, shake it a bit and put it back in place.
