Dishwasher Installation questions, answered by experts

The drain pump will naturally make a standard operational and draining sound several times throughout your dishwasher cycle. If you hear abnormally loud sounds like scraping, grinding, or clicking, you may have food debris or a piece of glass stuck in your drain filter. Avoid dishwasher repair by always scraping food off your dishes and loading the racks correctly.

Your dishwasher drain hose may have a clog if your dishwasher is full of water, your dishes aren’t getting cleaned, or water takes a long time to discharge into the garbage disposal.

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.

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.

Repair costs vary by issue, typically from $100 to $500, depending on the parts needed and labor involved.
