If you enjoy washing by hand, no! However modern machines use less water, detergent and power than ever before and wash hotter using really powerful cleaners giving a hygienic wash result. You can save around 500 hours a year so it is worth thinking about. If you have a small kitchen or live alone, choose a slimline model.

Look for models with adjustable baskets and flexible internal layouts for varying load requirements. For example, a tilting upper basket allows large 30cm diameter plates in the lower basket and extra flaps can be raised or lowered to cater for small items or large pans.

When you're shopping for appliances, you can think of two price tags. The first one covers the purchase price - think of it as a down payment. The second price tag is the cost of operating the appliance during its lifetime. You'll be paying on that second price tag every month with your utility bill for the next 10 to 20 years, depending on the appliance. Refrigerators last an average of 20 years; room air conditioners and dishwashers, about 10 years each; clothes washers, about 14 years.
