Below is a list of things to do and avoid when operating a dishwasher.
1. Do not wash crystal, gold plated china, pans made from cast iron, silver plated china, copper, kitchen utensils without a steel handle such as wood or plastic. Any of these products may be faded or break from continual dishwasher washes.
2. When unloading a dishwasher it is advisable to unload the bottom draw first. Most dishwashers do not dry out all of the water. So, when cups are removed from the top draw first, they may drop water onto the bottom plates and utensils.
3. Some dishwashers contain a filter which needs maintenance. You should periodically check to clear any residual waste or limescale from the filter.
4. Some dishwashers require salt and rinse aid alongside the detergent to perform at their maximum. The salt helps to soften the water and the rinse aid contains surfactants to stop droplets of water forming and smearing glassware and plates. Dishwasher salt is not the same as culinary salt, and is purged of impurities, manganese and iron. Inserting salt which is not designed for a dishwasher will more than likely damage the softening system.
5. Over or under filling a dishwasher has it’s disadvantages. When too many items are placed inside, then the dishwasher will have difficulty cleaning to it’s peak performance. Cups and plates may also knock against each other and become chipped. While under filling a dishwasher does not have any disadvantage to the cleaning performance, there will be a waste of detergent, water and electricity.
6. Check that the dishwasher sprayer and sprayer arm have a free motion to clean the whole of the load
