Household appliances allow the modern person to save time and effort. However, during operation, the parts of the devices wear out. As a result, it leads to malfunctions or damage. This also applies to dishwashers.
One of the most common issues related to dishwashers is when the appliance won’t drain. However, this isn’t necessarily a plumbing emergency.
Actually, you might be able to fix the problem by yourself without contacting a qualified plumber. When the dishwasher is not draining, here’s what you should do.
Check for Basic Issues
There are many reasons why your dishwasher may have water drainage problems. One of the most common is that the dishwasher is blocked or clogged. This could be due to a blocked drain or a faulty dishwasher pump.
A clogged sink or blocked filters can also cause it. Unclogging the dishwasher can be a simple procedure. By following a few simple steps to identify and fix the problem, you’ll quickly learn how to get your dishwasher running smoothly again.
Remember that before you start checking for basic issues or doing DIY jobs, you must turn off the appliance at the mains or unplug it.
Verify Proper Dishwasher Loading
Even though loading a dishwasher may seem like a pretty easy job that doesn’t require much knowledge, there are still right and wrong days of doing it.
It’s best to check your dishwasher’s manual because some models are more sensitive, and others require a special way to place the dishes and utensils on the rack. So, make sure you check the manual and read about the right loading techniques.
For some models, it is common to have water draining problems if you put oversized dishes or utensils that cause the appliance to interrupt mid-cycle, which leads to water collecting at the bottom.
In some cases, proper loading might solve the problem, but if the draining problems continue, then you should check the next possible issues.
Clear Clogs in the Drain Hose
The drain hose can connect directly to the drainage fittings or the sink drain. If these openings are blocked, water will not drain from the appliance. Try pouring some water through the drain hose to check if it is blocked.
To unclog the drain hose, you can use unclogging products. You can try unclogging it with a solution of equal parts baking soda and vinegar. Pour the solution into the bottom of the appliance and let it sit for about 15 minutes.
Next, you’ll want to run a rinse cycle at the highest heat. If the blockage problem continues, look for the help of a qualified plumber.
Unclog the Garbage Disposal Connection
A clogged garbage disposal connection is another possible issue if your dishwasher doesn’t drain. Most models are connected through the drain hose, which runs out to the garbage disposal drain.
If it is clogged due to food, objects, or food sludge, it is normal that it doesn’t drain properly. This problem isn’t as common as a dirty filter, but it happens sometimes and is worth checking the disposal connection.
Try running hot water down your sink and run the garbage disposal again to fix it. Sometimes, running it for at least 30 seconds should fix the issue. If not, it’s best to seek the help of a professional plumber.
Inspect the Air Gap
If the previous steps haven’t fixed the problem, inspecting the air gap is time. The sink’s air gap looks like a small, slotted cylinder below the sink near the dishwasher’s outlet hose. It keeps contaminated water from flowing back into the appliance.
If you notice any buildup or dirt, clean it out and reconnect it, ensuring the cylinder is properly secured. Then, try running the dishwasher again and see if you’ve fixed the problem.
Check the Drain Pump
The drain pump, just like the filter, can be blocked by leftover food, other debris, or buildup grease. This should be the next thing you check if the previous steps haven’t fixed the draining issue.
A clogged pump could stop water from draining after the washing cycle. The debris and buildup can usually be found near the impeller. You’ll need to get to the bottom of your dishwasher to check the drain pump.
First, you’ll have to disconnect the inlet hose and remove the base plate. To perform this task, the dishwasher must be put on its back to get full access to the pump.
If any of these tasks seem too difficult to handle on your own, it’s better to seek to help of a qualified plumber.
Clean the Drain Impeller
The drain impeller’s job is to push the water through the drain hose and into the garbage disposer. It isn’t hard to inspect the drain impeller. It’s located at the bottom of your appliance. When you locate it, check it for any signs of wear and tear. If the part is damaged, you must change it with a new one.
Addressing Persistent Drainage Problems
If the problem persists, your dishwasher may have a technical problem. Contact a licensed local plumber or other professional plumbing services to determine whether this is the case.
If, after correcting the problems above, your dishwasher continues having trouble with water draining, this could be a sign of water getting into the appliance’s base, the drain hose being below the water level, a faulty flow meter, or something else.
If you’re having a hard time determining what’s wrong with your machine, you better call a plumber.
Conclusion
You should not ignore the slightest signs that something is wrong with your appliance, as untimely action will undoubtedly lead to more serious problems or more expensive repairs.
And remember that if you’ve tried everything, but your dishwasher still continues having issues with water draining, it might be about time to call a professional plumber to help repair the machine.
And don’t forget that every appliance in your home needs proper maintenance and care. If you don’t have the habit of taking care of your appliances, don’t be surprised when they show signs of issues.
