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.

We recommend 2 strainers for every kitchen. The first is a solid stainless steel colander (one big enough to wash a lot of lettuce at once). The second strainer is a fine mesh conical strainer (called a chinois) which is a must for any serious sauce or stock making. A chinois is an expensive purchase, but with care it will last many years.

The insulation on electrical cords can become damaged by wear, flexing, or age. Do not use any cord that is stiff or cracked. Some clues that you may have an electrical problem are:

• Flickering lights. If the lights dim every time you turn on an appliance that circuit is overloaded or has a loose connection.
• Sparks. If sparks appear when you insert or remove a plug, they could be a sign of loose connections.
• Warm electrical cord. If an electrical cord is warm to the touch, the cord is underrated or defective.
• Frequent blown fuses or broken circuits. A fuse or circuit breaker that keeps tripping is an important warning sign of problems.
• Frequent bulb burnout. A light bulb that burns out frequently is a sign that the bulb is too high a wattage for the fixture.
