DIY Dishwasher Clog Repair


If you have noticed that your dishwasher isn’t cleaning your dishes as well as it used to, or if it isn’t draining properly, it may be clogged. There may also be water backing up into your kitchen sink after a cycle, or you may notice a gurgling or bubbling sound from your dishwasher. If you notice any of these issues, it’s time to look closely to find the cause.

Common Clog Reasons

The most common reason a dishwasher becomes clogged is debris from food, grease, lint, glass, or plastic. Food debris is the most common cause of a clogged dishwasher. Over time, bits of food can build up in the dishwasher’s filters, and they can even get caught in the spray arm. Eventually, it will cause a blockage. Grease can also build up, especially if you’re not using enough detergent. 

How to Fix a Clogged Dishwasher

First, locate the drain hose and check for blockages or kinks. If so, clear the blockage and make sure to straighten it out. Run a high-heat setting with some vinegar and see if that solves the problem. If that doesn’t work, you may need to clean the dishwasher’s drain trap. This is usually located under the sink, so you’ll need to remove the kickplate to access it. 

Advanced Troubleshooting

If your dishwasher is still not working properly, try cleaning the filter and spray arm. Every dishwasher is different, so consult the owner’s/operator’s manual before attempting to disassemble anything. Oftentimes, you can purchase a new filter if necessary. Additionally, check under the filter for any debris, such as plastic or food. Be careful in case there is a piece of broken glass that has fallen into the dishwasher base.

If all else fails, you need to call a professional to diagnose and fix the issue. If so, give us a call, and we can get it taken care of for you.
