Check the capacity. 'Standard' 60cm wide dishwashers can take 12, 14 or 16 place settings, whilst slimline 45cm models may cater for 7, 8 or 9 place settings. Compact dishwashers tend to be 45 cm wide and can be placed on the worktop or built in, depending on the model. They may take 4, 5 or 6 place settings.

Buying this "service deal" can be expensive but if you feel happier knowing that you are protected from breakdown for a few years, shop around insurance brokers to see how prices compare.
