Most of the time you throw your dishes into the dishwasher, add detergent, press a button and go. Sometimes, after several years, you suddenly realize your dishes aren’t getting sparkly clean as when you first began using the dishwasher. Maybe it isn’t draining well and there may even be a bad smell coming from it.
There are a few simple things you can do to prevent the dishwasher from developing some bad habits and cause you problems.
Check out the door seal. Over time & repeated usage (along with the drying heat) the seal will become weathered, just like the weather stripping on your front door and needs to be replaced. A weakened seal can cause leaks that can damage your floor or cabinetry, which could develop into an expensive problem. You can contact the manufacturer to get a replacement seal, or schedule a plumber to come out, inspect the appliance and replace the seal.
Just like the lint catcher in your dryer, the dishwasher has a screen in the bottom to collect large chunks of debris from your dishes. This screen should be cleaned often to prevent odors and allow for proper drainage.
Most dishwashers have moveable spray arms that can be taken off and washed in warm soapy water to remove any buildup. Be sure to clean each nozzle opening; you can use a soft brush or toothbrush.
Mold is a common problem for dishwashers. It’s a steamy, damp environment, ripe for mold and mildew growth. There is an easy fix and prevention: simply pour about 2 cups of white or apple cider vinegar into the dishwasher & run it on the heaviest setting. If you do this on a regular basis, it will help prevent mold.
Is your dishwasher level? Believe it or not, if the dishwasher is not level you will not get the optimum performance out of the appliance. Plus, an off-kilter dishwasher could cause drainage problems.
Was your dishwasher plumbed properly with a drain trap? That is a section of pipe that looks like a “U” close to the drain opening. It should be installed on the proper side of the drain to prevent odors and catch accidentally dropped items in the dishwasher (i.e. wedding ring)
A healthy dishwasher should give you many years of service with proper maintenance.
