Dishwasher Maintenance Tips

Return to Appliance Maintenance Tips


The plastic coating on your dish rack may wear off resulting in corrosion and rust. You can cap the damaged rack tines with slip-on rubber tips and touch up any metal showing with a liquid rubber type material. For best results, remove any rust present on the racks with sandpaper or a sanding block before applying the repair material. Repair kits are available in white and light blue.


Over time, the small holes in the spray arm(s) of your dishwasher may become clogged with toothpicks, glass, paper, hard water scale, etc. Your dishwasher will perform better if you clean out the small holes from time to time.

It is a good idea to clean out any hard water and/or soap deposits in the wash system, tank, and pump system. To do this, run hot water at the tap. Put the empty dishwasher into the regular wash cycle. Wait until the machine has filled with water and begins to circulate the water. At this time, add your cleaning product (white vinegar or Glisten) directly into the bottom of the dishwasher. Allow the machine to run the entire wash cycle. For best results, reset or advance the dishwasher to run again in the wash cycle without draining the treated water. We recommend performing this maintenance once or twice a year.


On many dishwashers, there is a filter near the bottom or under the lower spray arm that needs to be cleaned on a regular basis. Consult your owner's manual to find out how to remove and clean it. If the filter has holes in it, replace it to protect the pump and motor seals from particles that may be in the dishwasher.
