Why Won’t My Dishwasher Drain?

Nothing is more frustrating than running your dishwasher only to find that it’s not working. If you open your appliance and see a pile of dirty dishes and a basin filled with dirty water, you likely have an issue with your drain. This situation is most often an emergency as bacteria can build up in your dishwasher, creating a health hazard for your household. Remember to turn off the electric supply of your dishwasher before you check your appliance for a problem.


Let’s discuss a few common reasons why your dishwasher won’t drain effectively!


Common Reasons Why Your Dishwasher Won’t Drain


Here are the most common reasons why dishwashers don’t drain effectively.


1.   Interrupted Wash Cycle


It is possible that the dishwasher’s previous cycle was interrupted, causing your appliance not to drain. Hold down the cancel or drain button from the controls to restart or resume the process if you suspect this is the problem. Check your dishwasher’s instructional manual. If you didn’t keep it, you could typically find one online by searching for the manufacturer and model. In some cases, the manual will indicate a combination of buttons you can push to reset the system and force your appliance to drain.


2.   Dirty Filters


Your filter should be the first place you go if your dishwasher won’t drain. Dishwasher filters are an essential element that must be adequately cared for if you want your machine to function correctly. Soggy food particles can get stuck in the filters and keep the dishwasher from draining grease and other residues.


If filters aren’t cleaned regularly, they’ll clog at some point. It is best to practice cleaning your filters once or twice a month to keep your dishwasher working perfectly. You will need to remove all the filters, including the cylindrical filter. Then, you need to check for any leftover food particles that may have been sitting in the sump area, causing your appliance to clog.


3.   Blocked Drain Hose or Sink


If clearing the filters doesn’t work, a clogged drain pipe may be the cause of your dishwasher’s inability to drain correctly. Every dishwasher comes equipped with a drain hose to transport wastewater away. In most cases, it’s connected to the kitchen sink’s drain line.


In some cases, the drain hose may be kinked or jammed with grime and food debris. You will need to detach it from the dishwasher and remove any blockages. Your kitchen sink may also be the source of the issue. If you cannot unclog it with a drain snake or a plunger, consider calling a plumbing service right away.


4.   Damaged Drain Pumps


Drain pumps, like dishwasher filters, can become clogged with food debris and grease buildup. Ignoring these issues can eventually lead to damaged pumps. The impeller is typically where you’ll find debris that got inside the pump and caused damage. The impeller helps push the fluids through your appliance. Hard objects like broken glass pieces can be stuck in the pump, eventually clog it, and cause damage. You can often hear the pump struggle to suck water if it’s blocked.
