Identifying Low Dishwasher Pressure

To properly clean your dishes, your dishwasher needs to have a certain level of water pressure. If your dishes are coming out dirty, your system's water pressure may be too low. This often happens due to a clog in your system lines, which will need to be cleared out.

Why Are My Dishes Coming Out Dirty?

Your dishwasher uses a powerful combination of hot water and high water pressure to clean and clear the grime on your dishes. Without hot water or enough water pressure, your dishwaster will not function properly. So, if you're experiencing dirty dishes, your dishwasher water pressure may be too low.

How to check for low water pressure

  • Open your dishwasher and look closely at the spray arm(s). All the holes should be clean and clear of debris. If you see food or dirt in the holes, your spray arm is clogged.

  • Start a wash cycle in your dishwasher. After the cycle begins, listen closely for a swishing noise. This noise should be very distinct and loud enough to determine whether the water is swishing around freely or if it's obstructed somehow. If you can't hear the water inside swishing around, it may be a sign that there isn't enough water pressure.

  • After your dishwasher has been running for a few minutes, open the dishwasher door carefully. Inspect the dishes for water droplets. If your dishwasher has enough water pressure, all the dishes should be wet. If some are dry, there is a blockage somewhere that is lowering the overall water pressure and distribution.

    CAUTION: Stand back a bit and open the door carefully. Water shouldn't splash out, but it's best to be cautious.

Other issues

If the pressure seems fine, consider other reasons for dirty dishes.

What To Do If Your Dishwaser Water Pressure is Too Low

If the water temperature in your dishwasher is low, there must be something blocking the water from flowing freely. You'll need to find out if there is something lodged in your dishwaster system that is clogging things up.

Locating and clearing the source of a clog in your system is no small feat. Doing so may require assistance from a plumbing expert. If you need a hand, you can reach out to our Remote Assist experts for a virtual diagnosis.
