Clean Your Sink’s Air Gap
If you don’t have a garbage disposal, check your sink air gap. It’s a small, slotted cylinder below the sink near the dishwasher outlet hose.
To see if the air gap is the problem, remove it by turning it counterclockwise. Then clean out any debris with a stiff brush. After you’ve removed all the buildup, replace the air gap, secure it, and try running your dishwasher again.
Garbage Disposal Not Working And Sink Not Draining
With a clog in the pipes, your garbage disposal is no longer going to be working properly. The reason for this is because you are most likely going to be having issues with hard and tough food particles that get stuck in the drain.
On a similar note, another source of kitchen frustration is the garbage disposal. Everyone hates to see waste water backing up in the kitchen sink, and few things are more unsettling than hearing the grinding sound of a jammed garbage disposal. And these breakdowns are especially frustrating because a clogged sink or backed-up drain can be cleared out at home it may just take some elbow grease.
Garbage disposals can clog, preventing the sink and entire kitchen from draining. Garbage disposals should be emptied regularly and specialists recommend doing this at least once a week. You will have to turn off the power and water running to the disposal and then unplug it to get it out. You will have to dispose of the garbage from the sink and wait for the system to drain.
Tips To Keep Your Dishwasher Draining Properly
- Always turn on your garbage disposal prior to running the dishwasher to clean out food and debris in the system.
- Dont use drain cleaner in the dishwasher. Chemical drain cleaners like Drain-O or Liquid Plumber should never be used because of their caustic ingredients that can damage rubber parts of the dishwasher.
- Make sure youre using the right type of dishwashing detergent. Use only powder, liquid, tablet, or pod detergent specifically designed for automatic dishwashers.
- Check that youre using the right amount of dishwasher detergent. Homes with soft water require about a quarter cup of detergent . Hard water areas require a full cup of detergent for a good wash.
- Perform annual maintenance on your dishwasherthis includes cleaning the filter and trap with a stiff brush and hot, soapy water, cleaning the spray arm holes with a stiff wire brush, checking the dish racks for cracks, checking the drain hose clamps to ensure theyre properly clamped, looking for leaks and cracks in the door seal, and making sure the pre-heating mechanism is functioning properly.
- If you think theres an issue, address it quickly. Letting the problem sit can make the clog worse and may cause additional repairs. If the cost of a potential repair is holding you back, the cost of a home warranty may be more manageable. Warranty premiums are $25$67 a month, and you only pay a nominal service fee any time you have a repair for a covered appliance.

Three Things You Can Do When You Dishwasher Is Not Draining
- 1. Clear your garbage disposal. Often times, the water from your dishwasher will drain through your garbage disposal.

If your disposal is full, the water can back up and leave standing water in your dishwasher. Make sure to completely run your disposal and loosen up any clogs.
- 2. Clean your air gap. Many kitchens will have an air gap installed on the counter next to the faucet that prevents water from your sink backing up into your dishwasher. If the air gap is clogged with buildup, it can lead to your dishwasher not draining properly. One common sign of a clogged air gap is water flooding onto your counter. To clear the air gap, take off the cap and remove any debris that you can see.

How To Remove The Knockout Plug
Another common issue with the dishwasher and garbage disposal is a dishwasher that is not hooked up properly, and has drainage problems. In this instance, you likely just recently installed a new dishwasher and a small detail was overlooked.
Your dishwasher needs to be hooked up to the garbage disposal in order to drain successfully. To do this, you should remove the knockout plug from inside your garbage disposal and install the dishwasher drainage tube.
In order to remove the knockout plug, you need a hammer and a screwdriver. Locate the plug by poking into the drainage hole on your garbage disposal. If it inserts easily, the drainage plug has already been removed and the drainage problems are not caused by the knockout plug.
However, if the screwdriver hits something solid, this is the knockout plug. Use the hammer to lightly tap the back of the screwdriver around the perimeter of the plug until it falls into the disposal unit. Use your hand or pliers to reach down through the sink opening to retrieve and remove the plug.
With the knockout plug detached, you can tightly affix the drainage tubing for the dishwasher and successfully thwart your drainage issues.

Sink And Dishwasher Maintenance 101
Before you attempt to clean or fix your current plumbing problems, be sure to unplug your appliances from their power supply to minimize the risk of electric shock and injury. Turn both the cold and hot water supply valves off to prevent any water flow to your appliances.
It is also important to know that the running water in both your kitchen sink and dishwasher flow out through the same drainage line. So any clog or blockage within that main drainage line can cause water to backup and overflow into your kitchen sink. These clogs typically occur in four places: the dishwasher, the garbage disposal, the sink, and the air gap. Clogs in any of these four locations within your plumbing system can result in water filling your sink when you run your dishwasher.

Check And Clean The Drain Hose

If your dishwasher still seems to be clogged, there may be an issue with your drain hose. If the hose is located behind the dishwasher, you’ll have to pull your appliance away from the wall to access it.
Start by inspecting the hose for any kinks that may be preventing water from draining. If there are obvious signs that the hose is bent, try to straighten it.
If the hose doesn’t show any obvious signs of damage, check for a clog. Place a towel or small container beneath the connection between the hose and clamp to catch water, and then use pliers to loosen the clamp so that you can remove the hose and visually examine it for any clogs.
After looking for signs of a clog, try flushing the hose with hot water and watch to see if the water is flowing properly.

Clean The Dishwasher Sinks Air Gap:
Having problems with your dishwasher not draining? It could be a clogged air gap. An air gap is an important component of any dishwasher setup which prevents wastewater from backing up into the dishwasher and contaminating it. Cleaning out the air gap can help to alleviate this issue, as it removes any blockages from the vents in the pipe.
An air gap works by utilizing two small pipes connected to each other, one inside the sink and one outside of it. As water flows through the inner pipe, a vacuum is created that sucks away dirty water and food particles from within the sink. If these materials become stuck in either pipe, or if there is an obstruction blocking airflow, then this can cause your dishwasher not to drain properly. Luckily, cleaning out your air gap isnt too difficult!
Clean The Drain Basket:
If youve ever been left with dishes that didnt dry after running your dishwasher, the problem could be a clogged drain basket. In order to get your dishwasher working properly again and to ensure all of your dishes are getting effectively dried, it is important to regularly clean the drain basket. This small part plays an essential role in making sure water can travel through the dishwashers system and out of the door without any blockages.
The drain basket is located on or near the bottom of most dishwashers and it helps collect food particles, grease, lint and other debris before they cause a clog. If this area isnt cleaned regularly, these small particles can build up over time leading to a slow draining dishwasher that doesnt dry its contents properly.

Remove The Filter Clog
If your GE dishwasher is not draining correctly or slowly, the first thing that may be the issue is a clogged dishwasher filter.
A filter is a strainer that collects the food particles and protects the drained pump from getting blocked. If the filter gets filled with food particles or debris, it affects the draining operation.
To fix the issue, firstly, you must check the filter for blockage. If there is, you may remove it to restore the draining efficiency of your GE dishwasher.
Solution:
Take out the lower rack. Locate the filter grab, move it in a counterclockwise motion and pull it off. Some models contain fine filters, while some own ultra-fine filters, so you should access the filter you have.
Unfasten the filter components and clean the blockage and debris. It would be better to use lukewarm soapy water. You may use a sponge or a brush, anything you find suitable. Rinse with clean water and install the filter.
Move the filter clockwise and ensure the aligned arrow marks are equal. It ensures that the filter is installed in its position correctly.
Clean The Dishwasher Filter
You may not realize that your dishwasher has a filter, but most do, and it can quickly get clogged with food debris, water deposits, and bits of garbage. Regularly cleaning the filter, which is located at the bottom of the dishwasher, can help prevent clogs. Consult your manual and our dishwasher filter guide for helpful tips, especially if you are removing the filter for the first time.
If there is standing water in your dishwasher, use a wet vac to siphon any excess water before removing the filter. Once you have removed the filter, simply hand wash it in warm, soapy water. An old toothbrush can also help remove any hard-to-clean spots. Rinse thoroughly under warm running water. Do the same if your dishwasher has a secondary filter. Let both filters air dry before placing them back in the dishwasher.
