How a dishwasher works

28 How A Dishwasher Works

All the stages of a dishwashing cycle: how you get from crumb-scattered crockery to dazzling dishes. 

Your task is simple: Wipe off the food scraps ,pop the dirty plates into the dishwasher, no elbow grease required, and enjoy the four extra hours of free time each week you get by using a dishwasher. 

How a dishwasher works - the stages in each cycle
First, a powerful jet of water blasts dirt from your dishes – getting rid of burnt-on bits. 

A clean burst of water signals the main wash cycle and the detergent gets to work, using the spinning spray arms to wash everything inside and out. 

Hygiene is your dishwasher’s priority, so the water temperature rises up to 75°C to get things really clean. 

To guarantee an effective job, fresh water removes any remaining residue, then the rinse aid is released, which helps the drying process, and adds a brilliant shine. 

During this last hot rinse the temperature rises again, before the water drains and the latent heat (the heat left on surfaces inside the machine) dries everything to a gleaming clean. 

And it can still use less
This might make it sound as though the dishwasher’s using a lot of water. But, in fact, it could use less than you do when you’re washing up by hand: you can find out more here.
