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.

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.

Modern appliances reach higher temperatures quicker - and often hold heat longer. To avoid worktop damage, follow both the appliance manufacturers instructions and these rules:

• Always use the correct size of pan for the burner, placed centrally. An overhanging pan can scorch surrounding surfaces. Don't use two burners as one (e.g. for a large griddle) - it has the same effect.
• To reduce heat, turn the burner down instead of pulling the utensil partially off the heat source.
