1. Clean and deodorize the interior
Periodically use a warm rag and some household cleaner to wipe the space between the door and bottom of the tub. Food particles often collect here and lead to mold growth, as this location remains untouched during the wash cycle. Use a pipe cleaner or sewing needle to remove food particles, bits of paper or other debris from the spray arms’ small holes. Never use a toothpick, as the tip can break off inside of the wash arm. A deodorizer specifically for dishwashers makes it easy to prevent mold growth and keep the interior smelling fresh. A rust-removing solution designed for dishwashers will eliminate rust stains. You can clean the door (exterior) with warm water and a small amount of dish detergent.
2. Clean the filter
Your dishwasher may have a filter located near the bottom or under the lower spray arm. This filter should be inspected and cleaned regularly. Follow your dishwasher owner’s manual for specific instructions about how to properly remove and clean this filter, if equipped. If there are any holes or other damage to the filter, you’ll need to replace it immediately to protect the dishwasher’s pump and motor seals from damage.
3. Repair dish racks
If the plastic coating wears off of your dishwasher’s top or bottom rack, repair as soon as possible. Use replacement tine tips, which are available in an array of colors to match your unit’s racks. Use touch-up paint to cover flaking paint. If left alone to rust, the racks may corrode, allowing small shards of rusty metal to enter your dishwasher’s pump, leading to expensive repairs.
4. Don’t overload it
Cramming two loads into one load will restrict the water spray patterns, which will prevent proper cleaning and require you to have to rewash, wasting water.
