General Dishwasher Maintenance Tips

A dishwasher is generally a low maintenance appliance. Below are some basic tips for keeping your dishwasher running in tip-top shape. (Note: Before doing any work on your dishwasher, turn off the power at the circuit-breaker box.)
Don’t Get Zapped. Dishwashers have built-in water heaters and motors which can consume a lot of electricity; couple that with all the water a dishwasher uses and you can see how improper wiring and connections can put you at risk for electrocution, fire or power outages. A ll dishwasher should always be plugged into a grounded outlet or wired direct. And your main socket must be rated adequately to handle the large load required by most dishwashers.
Make Sure Your Dishwasher is Level. If your dishwasher isn’t level, it could leak. To check, open the door and place an air-bubble level along the edge inside. If the dishwasher isn’t level, raise or lower either side by adjusting its “feet” or add a wedge to balance correctly.
Check Gaskets for Cracks and Deterioration. These are the rubber or plastic seals along the dishwasher door that provides a water-tight seal when you close. If you start noticing water around your dishwasher, it could be due to faulty gaskets. If the gasket is damaged, remove it by unscrewing it or prying it out with a screwdriver. You can get a replacement gasket at a hardware store or order one from the manufacturer. Before installing the new gasket, soak it in hot water to make it more flexible.
Check Sprayer Arm for Clogs. Over time Food particles, mineral deposits and other debris can clog the holes in the sprayer arm. It is essential to clean these small holes from time to time to enable the dishwasher to work more efficiently. Remove the sprayer arm periodically and soak in warm vinegar for a few hours to loosen any obstruction. Then clean out each spray hole with an awl or a pipe cleaner.
Check and Clean Screens and Filters. Your dishwasher should have a screen or filter located near the bottom of the dishwasher above the food drain to catch any large food or debris; they need to be cleaned regularly to avoid clogs (at least every other week). Your dishwasher owner’s manual should provide instructions for removing and cleaning the filter. If the filter has holes, it needs to be replace in order to prevent harm to other parts of the dishwasher. Also, inspect and clear out any food or debris that might be trapped in the food drain.
Invest in a Repair Kit. Notice any exposed metal, nicks or corrosion on your dish racks? These can cause rust and stains to dishes and dishwasher walls. Most hardward stores sell repair kits that allow you to quickly mend worn or chipped plastic.
