When choosing a new dishwasher there are many decisions to be made. There are easy decisions like what colour you want it to be and the slightly more complicated decisions such as how many programmes you need. Dishwashers come in a variety of sizes: full size, compact, slimline or integrated enabling you to find a model that fits your kitchen. Other information available includes the cleaning performance, drying performance and energy efficiency. These are graded from A to G, A being the best or most efficient and G being the worst. In general the more expensive the dishwasher the better it performs in these areas. If the noise of the appliance is a concern then you need to look at the noise level, this is measured in Db and the lower the value, the quieter the appliance. If you don't want to waste too much water then you will need to know the normal water consumption, this is measured in litres per cycle.
Other types of wash available on some dishwashers include delicate washes, pre-washes, a half load wash and an economy wash option. Depending on the plumbing available where the appliance will be located, you may also be interested in whether your dishwasher is filled using hot or cold water. The decision you make will effect the amount of hot water taken from your tank and whether gas or electricity is used to heat the water. Other features that might be included on your dishwasher to make it easier to use are an LED display showing time to end of cycle, salt refill indicator, electronic controls, removable cutlery basket and a programme progress indicator.
