You May Have a Clogged Garbage Disposal
A clogged garbage disposal is a common culprit for kitchen plumbing functioning poorly, and could cause the dishwasher to back up in the sink. Removing the drain plug — typically located covering a hole where the disposal meets the dishwasher — can allow the water to drain properly from your sink or dishwasher.
Clogged Air Gap
Air gap devices are installed at the countertop level in an effort to prevent backflow into the dishwasher due to a siphoning effect. Dishwasher air gaps have two branches of hose with an unpressurized gap of air. This helps prevent cross contamination between the sink and dishwasher. Remove the lid and insert beneath it to look for any clogging materials.
Debris Blocking the Sink Drain or Pipes
It’s natural for a few stray particles of debris or food to get into the sink drain and cause a clog in the pipes that should carry them away. You can use a liquid solution or a snake hose to clear them out.
Dishwasher and Drain Pump Clogs
If water is standing in the dishwasher, you should check the drain pump at the bottom and look for kinks in the drain hose on the back of the machine. The pump’s job is to remove water through the drain hose, but over time they can become clogged or simply wear out. Should you need help replacing it, call a kitchen plumbing professional.
Preventative Maintenance Tips
There are a few ways to avoid clogs that cause sink water to drain into the dishwasher, including:
- Scrape food off dishes before washing them.
- Pour used cooking grease into a jar that you dispose of separately.
- Regularly cleaning the dishwasher drain.
- Use detergent recommended for the dishwasher.
- Don’t use more detergent than advised, as it leaves behind clogging residue.
