Plumbing Problems That Can Prevent Your Dishwasher From Draining Properly


Your dishwasher usually connects to your kitchen sink drain. It may attach above the garbage disposal, and then the water goes through the disposal before heading on through the drain. When your dishwasher won't drain or is backed up, the problem could be with the kitchen drain rather than the dishwasher. Here are some things to try when your dishwasher won't drain.

Run The Garbage Disposal To Clean It Out

If your dishwasher empties in the garbage disposal, a clog in the disposal will affect how well the dishwasher drains. You may need to clear out the disposal and run it for a short while to get it cleaned out so water flows through freely.

Check If The Sink Drain Is Slow

One of the first signs of a clogging drain is when the drains empty slowly. Run water down the sink drain to see if it clears fast or if it seems to take longer than usual to go down the drain. If your drain is slow, try to unclog it before it backs up completely. You may find that, the next time you run the dishwasher, the water backs up in the sink if the clog is bad enough.

You can often clear a kitchen clog by using a plunger or using a home remedy such as vinegar, baking soda, or hot water. If you can't get the clog to budge, call a plumber. A plumber can use a snake or hydro-jet to clear out your kitchen drain. They can also check the drain from the dishwasher to make sure water is flowing freely again.

Clean The Air Gap

If your sink plumbing has an air gap, you may want to check it or have the plumber check it to see if it is blocked with debris. An air gap is usually on the sink beside the faucet. Its purpose is to keep water from the sink from flowing in the dishwasher, and when it's clogged, water has a hard time draining out of the dishwasher.

Check The Dishwasher Manual

If your sink plumbing seems to be working fine, the problem might be in the dishwasher rather than the sink drain. Check your manual for instructions on troubleshooting the dishwasher when it won't drain all the way. The problem might be a jammed pump, a kinked drain hose, or a clogged drain filter. If you can't figure out what's wrong, call a plumber for help since a dishwasher that doesn't drain properly has the potential to flood your kitchen.
