Regular use helps keep interior dishwasher parts functioning properly and the interior clean. Try to run your machine at least once every two weeks as part of your dishwasher cleaning schedule.

Every six months, running two cups of white vinegar through your dishwasher (place the vinegar where you put detergent) will help deep clean the unit to boost performance.

If your dishwasher isn’t draining, some common causes include a clogged drain filter, drain hose, or air gap. Also, if you have a garbage disposal, a clog in the disposal can back up your dishwasher since they share plumbing, as can a clog in your kitchen sink’s plumbing. A handy DIYer may be able to figure out how to unclog a dishwasher, but you may need to call in a plumber if you can’t locate and clear the clog yourself.

Professional services ensure correct installation, verify water-tight seals, and safely address plumbing and electrical connections in dishwashers.

You should deep-clean your dishwasher every month for optimal performance. A simple scrub down using a homemade vinegar liquid solution is all you need, but don’t use cleaners that aren’t for dishwashers. 

If your dishwasher needs repair, expect to spend between $50 and $100 or $100 to $200 per hour to hire a dishwasher repair technician to service your machine.

Treat hard water with water treatment tablets to keep your dishes from getting spotty in between washes. Drop one of these into your dishwasher monthly and run a basic cycle with the machine empty.
