It’s something odd to observe – when the dishwasher runs, the sink fills with water. Yes, you heard that right, and you are not alone in this regard.

Whether it’s the oddest plumbing quirk or just a plain problem, knowing what’s happening can save you so much time and stress.
In this post, we go deeper into why this is occurring and give actionable tips to keep your kitchen running like clockwork. Don’t let a sink full of water ruin your day!
Common Causes of the Problem
Some common causes related to the problem of a sink filling with water when running a dishwasher begin with the garbage disposal. With a clogged disposal, water does not drain and results in backup problems in the sink. If there is a slow or malfunctioning garbage disposal, this problem will occur. Also, when the major plumbing line is defective, it may lead to the backup of water in the sink and the dishwasher.
Making sure that everything will drain properly is the principal approach to the prevention of these disturbing back-ups. Thankfully, many of these problems can be remedied by simple repairs to the plumbing. If water fills up your sink while the dishwasher is at work, now is the time to find that out and deal with it!
Clogged Dishwasher
Water fills a sink when a running dishwasher has clogs. First of all, one should check the drain hose for kinks or blockages. And if chances are that it does have bends in it or it is clogged, that would restrict the water from flowing out of the system. Next, check the back of the dishwasher for a clogged drain due to food or debris.
Another reason for water to back up into the sink from the dishwasher could be a dirty filter inside the dishwasher. The filter of the dishwasher should be cleaned on a regular basis to avoid this problem.
Finally, taking care of the brand and quantity of detergent used can avert buildups and clogs. These should be kept clear to ensure your dishwasher performs well and drains correctly.
Problems with the Air Gap
An air gap in the sink of your kitchen prevents water from running backward toward your dishwasher. When the air gap becomes clogged, water could back up into your sink instead. Normally, this is corrected simply by checking blockages or debris in the air gap device. Sometimes these become blocked from the inside by food particles to such an extent that they prevent proper drainage.
Generally, cleaning of an air gap can resolve the problem. A bottle brush is very helpful in cleaning the air in the standing water gap and seeing that it’s clean. On a regular basis, check your air gap for blockages and clean as needed to maintain healthy dishwasher and sink drainage to avoid water backups.
Garbage Disposal Interference
The dishwasher drain hose is commonly clipped onto the garbage disposal in most kitchen setups. If your garbage disposal becomes clogged or malfunctions, it can serve as a blockage to hinder your dishwasher from draining. This may be evident through water backing up into the sink from running the dishwasher. Solve this issue by first attempting to seek blockages within the disposal. That alone will often clear up the problem.
Also, check if you have forgotten to remove the plug on your garbage disposal drain. This can obstruct your dishwasher’s drainage. In fact, leaving the plug in will block the water from draining completely. Keeping your garbage disposal clean and running properly will keep your dishwasher draining and not have any problems with a back-up in your sink.
Vent Pipe Issues
The system of pipes relies on proper venting in order to flow well. These clogged or obstructed venting pipes may then apply negative pressure on water flowing down the drain, thus it may cause your sink and dishwasher drainage problems. Impeded airflow causes drainage backup or failed drainage.
Since the vent pipe occupies many areas such as your roof, a professional plumber will be required to check on the problem. This will keep your ventilation in good shape, allowing your plumbing to work effectively, and preventing any water backups.
Drain Clogs
Drain clogging is one such incident that causes your dishwasher to fill when the water tank is plugged in. Over the years, grease and debris buildup starts in the draining sinks and washing machines, blocking the water flow course, which restricts the flow of water. As it is removed and the dishwasher drains to fill the basin, the clogs may cause backsail water.
Solution: Use a plunger to remove the clogged vessel. With water, it may take up to 30 minutes to remove a scuff. Regular washing of drains in the kitchen prevents future leakages from taking place.
Preventative Maintenance
This can easily be prevented by taking only a few precautions to help stop water back-up in your sink and dishwasher. Scrape food off of your dishes before placing them into the dishwasher to stop clogs of drains. Make sure cooking grease is never poured down the drain but always instead placed in another container. Run cleaning through the dishwasher drain to keep it clean, and try not to use too much dishwashing detergent, as this will cause a build-up.
Also, the air gap device must be cleaned and serviced on a periodic basis to avoid blockage. These simple practices will help you to ensure that the installed air gap in your plumbing system works properly and minimizes the chances of any backup.
Steps for Troubleshooting
Suppose at any instant you find water back-up occurring linked with running the dishwasher. Check the loop of the drain hose to make sure that it is above the kitchen sink drain to avoid any backflow from occurring. If you think that something might be clogged, try plunging, snaking the drain, or taking a mixture of baking soda and white vinegar.
Also, check and then clean the dishwasher strainer on a regular basis to avoid all buildups. If needed, loosen the setscrews on the drain hose clamps and run a strong current of water through the hose into the drain line to help clean out the blockages. These steps will solve the proper drainage problem.
When to Call in a Plumbing Professional
Plumbing problems sometimes can be really puzzling, and that is nothing to feel ashamed about when asking for assistance. If you are not confident in your ability to perform do-it-yourself plumbing repairs, or if the problem seems complex, it would be best to call a professional plumber.
If your problem persists or you just can’t seem to know how to fix it after following these steps of troubleshooting, you should call a plumber for assistance: a professional plumber can find the problem and fix it, whether it is a clogged garbage disposal, a problem with the air gap, or a blockage in the vent pipe.
