We have a rule in our house (one that I imposed) that whoever cooks doesn't have to clean. The issue with this arrangement in my household is that I do the cooking and my lovely other half doesn't believe in doing regular, after every meal type hand-washing. I can't stand to see the dirty dishes in the kitchen and also the dishes being unavailable because they are waiting to be cleaned. So the fall-back, sanity arrangement is a dishwasher. We have had one in our houses for the last three years and it certainly has created extra time for all in the house.
We are about to move to a new house and one of my dilemmas is there is no dishwasher. I am completely daunted by this and have started my investigation into the type that I will purchase once we move in. I have just come across a couple of websites that can assist people in investigating the energy and water efficiency of dishwashers currently available on the market.
The Energy Rating website specifically discusses the amount of energy that each dishwasher model uses and the Water Efficiency website discusses water usage. Both of these websites have various options so you can either narrow or broaden the criteria and features that you would like in your dishwasher.
