Consider which accessories might be beneficial. Many models can be supplied with a draining basket, chopping board and strainer bowls. A drainer extension can be useful for sinks without a drainer where worktop space is limited in a small kitchen.

Choose a dishwasher with sturdy compression springs in the door. Also look for tough, lightweight nylon or graphite racks with cushioned tips that protect glassware and cookware. Weimer recommends choosing a model with a rack design that provides the largest, most flexible interior space and is configured for your belongings, including odd-shaped pieces.
