Will I Need A New Dishwasher If It’s Not Draining
Not necessarily. In the vast majority of cases, a clogged filter or drain hose is to blame, and your dishwasher should be running normally after you’ve cleaned those parts of the machine.
Using your dishwasher correctly is also important. Jake’s advice is: ‘Always be sure to rinse plates and dishware before loading them in the dishwasher to increase the longevity of the unit without problems. Also, be careful about what you put down the kitchen sink, as grease can accumulate and cause problems for anything else draining through the same line.’
Can I Use Drano To Unclog A Dishwasher
It can be tempting to just chuck some Drano inside your dishwasher and hope for the best. Our dishwasher experts strongly advise against this. Jake is emphatically anti-Drano in dishwashers: ‘I would never use Drano in a dishwasher. Drano can break down a lot of materials and can damage your dishwasher. I would never risk it. Instead, you can consider safer alternatives like baking soda and vinegar, or enzyme drain cleaners .’
David Mason, home solutions expert and owner of The Knobx Company , adds that ‘Drano is a caustic household cleaner that should not be put in a dishwasher. The high temperatures in the dishwasher could cause Drano to explode.’
Just because a product is easy to get, it’s not necessarily the best product to tackle your problem. ‘There are powerful chemicals in some sink unblockers that, if misused, can be dangerous. Drano is one example of a chemical that is potentially harmful. It’s important to always read the label on these products and follow the instructions carefully.’

4- Drain Hose
The function of the drain hose is to drive dirty water out of the dishwasher and into the kitchen sink. This drain hose is slightly higher, and this loop serves a purpose.

Before checking the dishwasher components that could be responsible for the drainage problem, check that the pipe the dishwasher drains into is not clogged. If the dishwasher is connected to a garbage disposal, make sure the disposal is clear of debris. Note that the garbage disposals drain tube that connects to the dishwasher drain hose can become clogged. Detaching the drain hose and clearing the disposals drain tube may fix the drainage issue. If the dishwasher has been recently installed, make sure the garbage disposal knockout plug in the garbage disposals drain tube has been removed.

What Causes A Dishwasher Not To Drain Completely
A dishwasher not draining completely can be caused by several factors. The most common causes are a clogged drain hose, a malfunctioning pump, a defective drain valve, or a blockage in the drain pump impeller.
Additionally, if your dishwasher is not level, it can also prevent it from draining properly.
To troubleshoot the issue, you should first check that the drain hose is free from blockages and not bent. If it is, try straightening it out and make sure that it is properly connected to the sink or garbage disposal.
You may also want to check the garbage disposal for any blockages, as this could prevent the water from draining properly.
If the drain hose and garbage disposal are both clear, you will likely need to replace the pump, drain valve, or impeller. All three of these components can be replaced fairly easily, although you may need a professional for any more complicated repairs.
For best results, you should make sure to check your dishwashers manual for instructions on how to remove, inspect, and fix any of these parts if needed.
Signs Of A Clogged Dishwasher Drain
There are several obvious signs that your dishwasher drain is clogged if:
- You have food bits stuck in the filter
- The dishwasher keeps shutting off without completing a full wash cycle
- Youve checked the garbage disposal is clear, so its not clogged here
- You see a pool of water in the bottom of the dishwasher, right by the drain
The ridged drain hose is usually connected to your sink or garbage disposal and can be found by opening the cupboards under your skin.

Check The Drain Hose Attachment
Though the bottom of your dishwasher is below your sink drain or garbage disposal, the dishwasher drains upward into the sinks discharge port or disposal, propelled by a built-in impeller pump.
The first thing to check if the water is not draining from the dishwasher is the drainpipe from the dishwasher to the disposal.
Terminology note: The word pipe almost surely refers to a flexible tube commonly called a discharge or drain hose. This tubeor hosehas rubber fittings on each end. End 1 is affixed to the dishwasher itself and may require pulling the unit out of its location to access it. End 2 is affixedprobably by pipe clampto the sink drain discharge port or disposal.
Remove End 2 and check that its clear of debris, so have a rag on hand. Also, check the fitting on the discharge port or disposal itself. Make sure this is unobstructed and reasonably muck-free.
Finally, the tube itselfespecially if it is corrugated or ribbedmay simply have accumulated years of food waste. If this is the case, clearing it with a wire or coat hanger may work, at least to get you through a holiday. However, long term, it may be best to replace the dishwasher drain tube.
Make sure, too, that the hose isnt jammed by a poor installation in the first place or kinked by items that have accumulated under the sink. If you can, position the tube so it is above the entry point into the discharge port or disposal.
The Drain Hose Or Sink Is Blocked
If cleaning your filters hasnt resolved the issue, then the next thing that could be preventing your dishwasher from draining is a blocked drain hose. The drain hose is an essential component of any dishwasher as it carries dirty water away from the appliance. It is usually connected to the same drain line as the kitchen sink.
While unlikely, the drain hose could be clogged with built-up grime and food debris or may be kinked. To clean out the drain hose, youll need to remove it from the dishwasher and sink drain.
The problem could also lie in your kitchen sink. A blocked sink drain is a simple fix if you have a plunger or drain snake. If you require additional support, our is only a call away.

Inspect The Drain Hose
If you’re still having issues you should inspect the drain hose. Jake’s advice is to ‘loosen the dishwasher drain hose clamp and remove the drain hose. Make sure the drain hose is clear by blowing in it. If it bubbles into the dishwasher, the drain hose is clear.’
Elyse also warns those with new dishwashers that they may be experiencing an installation issue: ‘The drain hose should have a loop in it to keep dirty water from flowing back into the dishwasher after it drains. If it’s not looped, that could explain your problem. On the other hand, you don’t want any tight kinks in it that could cut off water flow.’
Air Gap And High Loop
If your dishwasher drain hose does not connect to a garbage disposal, it may connect to an air gap. If you do not have an air gap, the drain hose may be positioned in a high loop underneath the sink. Both the air gap and high loop are designed to stop wastewater from flowing back into the dishwasher during the draining cycle. If the air gap is clogged or the drain hose is not in a high loop position, then water backing up and not draining may be causing the drainage issue.
The air gap is usually a fitting mounted to the sink or kitchen cabinet. The air gap works by sending air into the hose, which eliminates the negative pressure that can cause the discharged wastewater to return to the dishwasher. The air gap can be inspected and cleaned of debris by removing the cover and cap.
The high loop method works by looping the drain hose up so that it is secured just under the sink. Check the dishwashers manual for the correct specifications for your dishwashers drain hose.

- Loosen the hose clamp on your drain tube where it connects to your garbage disposal or kitchen sink drain. Do this by turning it counter-clockwise with flat-head screwdriver.
- Put the drain hose in a bucket and set your dishwasher to drain by pressing the drain/cancel/start button for three seconds. Then close the dishwasher door to start it.
- While the drain tube is in the bucket, shake it to loosen the obstruction.
- When water comes shooting out, let it continue until its fully drained. If the bucket fills up, open the dishwasher door to stop the drain.
- Wiggle the drain hose back onto the garbage disposal unit or kitchen sink drain and tighten the hose clamp.
Pro tip: If you just installed a new garbage disposal before the dishwasher drain problem occurred, the cause may be a plastic plug inside the tube that connects to the dishwasher drain. To remove this plug, put your flat-head screwdriver in the disposals drain tube pipe and hit the back of the screwdriver with a hammer. That will knock out the plastic plug.
