Dishwasher Not Draining

Problems with your dishwasher don't necessarily have to result in you running out to buy a new unit. If your dishwasher is not draining, in many cases, there's a simple solution. Don't get overwhelmed thinking you need to be a handyman or have extensive experience to get this done. Here are a few things you can try to rectify if your dishwasher is not draining properly.

If there's water in the bottom or your dishwasher after the cycle has completed, you can try these simple tips to troubleshoot what the problem might be with your machine.

Diswasher Not DrainingCheck the Hose

Inspect the dishwasher that connects the dishwasher to the garbage disposal or drain. Make sure that this line is not kinked, which could cause water to reamin in the tub.

Clean Out the Drain Tube

Cleaning out the drain tube is easy enough. Simply disconnect the drain tube from the air gap. Now, make sure it’s not plugged up. If it is, clear out any debris before reconnecting it.

Check for Proper Drainage

Check your sink for proper drainage. If you have one, run the garbage disposal for a few seconds. In most cases, your dishwasher will be set up to drain out through the garbage disposal. When thae garbage disposal is clogged, so is the dishwasher since there's nowhere for the dishwasher water to go.

Check the Filter

Check the filter in the tub of your dishwasher. If there's any trash or debris, clear it out. Even though most modern dishwashers have built-in grinders, things like food and paper can still block the filter and cuase the tub to not drain properly.

Check the Air Gap

Keep in mind that not all dishwashers have an air gap. Look for a silver device next to your faucet -- this is the air gap. If water comes out of from here, then the clog is between the air gap and the garbage disposal. In order to unclog the air gap, you’ll need to remove the air gap cap. Locate the large tube that goes directly into the garbage disposal. Clear the tube of any blockage using a bottle brush.

Test the drain valve

If you have a drain valve that keeps water from draining back into the dishwasher, you'll want to check this as well. In order to test the drain valve, push on the valve bracket to make sure it moves freely. If it's frozen, the electrical solenoid that powers it may have burned out and need to be replaced.

If none of these methods work, you may have a larger plumbing problem with your dishwasher or drains. Neil Slattery Plumbing, Heating & Cooling is available to assess the situation and provide professional assistance. Simply call us at 732.223.8320, and we’ll be there right away to help.
