What To Do When Your Dishwasher Is Not Draining

Have you ever found yourself dealing with a dishwasher that just won’t drain? Many of us have experienced this issue, and it can be a real hassle. Luckily, there are steps you can take to get your dishwasher draining properly again. In this article, we will walk through what to do when your dishwasher is not draining, so you can get back to your daily routine in no time.

If you’re like most homeowners, the last thing you want to deal with is a clogged or slow-draining dishwasher. Not only does it create extra work for washing dishes by hand, but it also puts a strain on your plumbing system. That’s why it’s important to take action as soon as possible when your dishwasher isn’t draining properly.

From cleaning out the drain hose and filter to checking the garbage disposal and air gap, there are several steps you can take to fix a clogged or slow-draining dishwasher. Read on for detailed instructions on how to get your dishwasher running smoothly again!

Check The Drain Hose

Troubleshooting a malfunctioning dishwasher can be like searching for a needle in a haystack. Thankfully, there are some steps you can take to get your machine draining properly again. Firstly, check the drain hose. This is the pipe that runs from the back of your dishwasher and connects to your kitchen drain. If it’s kinked, clogged or disconnected, it won’t be able to effectively remove water. Visually inspect it for any obstructions and make sure it’s connected securely at both ends. If you’ve got an older model without a built-in garbage disposal, you’ll need to clear out any debris trapped in the hose before proceeding further. Next up, unclog the drain line. This is typically done with a combination of plunging and snaking the line with an auger cable. Start by plunging several times until the clog has cleared; if this doesn’t do the trick, then use an auger cable to snake out any remaining blockages from deeper within the pipe system. Finally, ensure that all valves and connections are secure and turn on your dishwasher test cycle to see if it’s draining correctly now — if all goes well, you should be good to go!

Unclog The Drain Line

Are you having trouble with your dishwasher not draining properly? If so, then don’t fret as this issue is likely a simple fix! Let’s take a look at the steps involved in unclogging the drain line.

The first step to unclogging a drain line is to identify exactly where the clog is located. A few key spots to check for blockage are: • Within the hose itself • Any connections between the hose and sink • The garbage disposal • The air gap, if your dishwasher has one.

To actually clear out any blockages, it’s time to get your hands dirty! Start by using a plumber’s snake or auger to work through any clogs within the hose itself. For any connections between the hose and sink or garbage disposal, use a wrench and unbolt them before cleaning away any debris that may have built up over time. Then when you’ve reassembled everything back together, make sure that all of the connections are secure. Finally, if your dishwasher has an air gap fitted then clean away any food particles that may be stuck inside it.

With these steps completed it’s now time to move onto checking for a blocked filter or pump – but first let’s make sure everything is working as it should be by running a cycle on your dishwasher after reconnecting everything!

Check For A Blocked Filter Or Pump

Moving on, let’s check for a blocked filter or pump. If your dishwasher isn’t draining correctly, the filter or pump may be clogged with food particles and debris. This can prevent water from draining properly. To troubleshoot this issue, you’ll want to take off the lower kickplate and locate the filter or pump. If it appears to be clogged with food debris, you’ll need to remove it and clean it out thoroughly.

Once you’ve removed the filter or pump, use a soft-bristled brush to gently scrub away any residue that has built up inside of it. Be sure to pay special attention to the corners of the filter or pump where most of the gunk tends to accumulate. It’s also important not to use any harsh chemicals as they can damage your dishwasher’s internal parts.

After cleaning out the filter or pump, reassemble everything and test your dishwasher again for proper draining. If all goes well then you should have successfully fixed your drainage issue! Onward we go with cleaning out any debris that could be blocking the drain line…

Clean The Filter Or Pump

Unclogging a dishwasher can be like a game of detective, but with the right tools and steps it’s a puzzle you can solve! Cleaning the filter or pump is an essential step in getting your dishwasher draining properly again.

Let’s get started. First, open up the filter compartment by removing the screws that hold it in place. This will likely require a screwdriver; make sure you have one handy before beginning. Once you have access to the filter, use running water to remove any clogs or debris that may have built up. Be careful not to damage the filter while cleaning it. If there are any cracks or blockages in the pump, see if you can repair them or replace the part entirely.

Now that your filter and pump are clean, take a look at them for any other signs of damage. Make sure all components are securely fastened back into place when finished. After that, you’re well on your way to having your dishwasher draining smoothly again!

Inspect The Discharge Hose

Alrighty, now we’re onto the fifth step in diagnosing and fixing a dishwasher that isn’t draining. We’ll be taking a peek at the discharge hose. This is the bit of pipe that’s usually hanging out behind the lower front panel of your machine. If it’s clogged or kinked, then it could be causing drainage issues.

So, first thing to do is to locate and remove the discharge hose from your dishwasher. You may need to unscrew some bolts or screws to get access. Once you’ve got it out, have a good look at it to make sure there’s nothing blocking it or preventing water from flowing freely out of the machine. Also check for any cracks or signs of wear and tear that might indicate damage.

If everything looks OK with the hose, you can go ahead and put it back into place, making sure that all connections are tight so that there’s no leakage when the machine is running. That should take care of whatever problem was causing your dishwasher not to drain properly! Now all you need to do is move on to checking the air gap…

Check The Air Gap

Alright, now that we’ve inspected the discharge hose, let’s move on to check the air gap. The air gap helps to prevent dirty water from flowing back into your dishwasher. It’s usually located on the countertop near your sink between the sink and the dishwasher drain hose. If it’s clogged with debris or gunk, then it can cause your dishwasher to not drain properly.

So, here’s what you should do: First, have a look at the air gap and make sure there are no blockages or clogs. If there are any blockages or clogs, get rid of them right away. You can use a toothpick or a wire hanger to remove any debris that might be stuck in the air gap. Make sure to run some hot water through it afterwards as well.

Once you’re done clearing out any blockages or clogs from the air gap, try running your dishwasher again and see if it drains properly this time around. If it does, great! But if not, then we need to take another look at it and move onto cleaning the dishwasher tub next.

Clean The Dishwasher Tub

When dealing with a dishwasher that won’t drain, the seventh step is to clean the dishwasher tub. After all, if your dishwasher isn’t draining, it’s likely due to a clog or blockage. According to The American Cleaning Institute, Americans spend an average of 12 minutes doing dishes every day. That means over two weeks of dishes are spent in the dishwasher each month!

Cleaning out the dishwasher can be done in several ways. You can use a special cleaner designed for cleaning out the tub, or you can make your own solution with vinegar and baking soda. Make sure to remove any large food bits from around the filter before washing with either solution. If you have hard water deposits on your dishes or inside your tub, adding some citric acid crystals will help break them down and dissolve them away.

TIP: Before using any chemicals inside your dishwasher, be sure to read and follow all label instructions carefully! Even if you’re making your own cleaning solution, double check that it won’t damage any of the components or finishes inside the machine before you go ahead and use it.

Check The Drain Valve

It may seem like an unusual solution, but before reaching the conclusion that the dishwasher needs to be replaced, it’s worth checking the drain valve. If you’re already deep into troubleshooting your dishwasher, this eighth step in the process might just be what you need to get it back up and running.

So how do you go about inspecting the drain valve? First of all, locate where it is located within your machine. You can usually find it on the bottom of the appliance near the hose connection. To gain access to the valve, unscrew or loosen any fasteners holding it in place. Look for clogs or debris that could be blocking it from draining properly and remove them if necessary. If there are signs of rust or corrosion, then you should replace the valve entirely.

Once everything looks clear and in working order, reassemble and tighten any screws holding the valve in place. Then run a cycle with hot water and detergent to test if it’s fixed. If water is still not draining properly after this step, then move onto inspecting the door gasket for any signs of wear and tear or damage.

Inspect The Door Gasket

The door gasket of a dishwasher is like the vehicle’s brakes: it needs to be in top condition before you can set out on your journey. Inspecting it is an essential step when your dishwasher isn’t draining. Don’t worry, though–it’s easier than you might think!

Start by seeing if the gasket is properly sealed and installed. If the plastic edges are curled or damaged, it won’t work as well as it should. Check for any signs of leakage around the door too–this could be a sign that something’s wrong with the gasket.

If the gasket looks good, you’ll want to make sure there’s no debris stuck in its crevices. Take a soft cloth and clean out any food particles or other bits of dirt that have built up over time. This will help keep things running smoothly as you get your dishwasher back up and running again.

Now that you’ve inspected your door gasket, it’s time to move onto cleaning it–a crucial part of getting your dishwasher draining again!

Clean The Door Gasket

Now that you’ve inspected the door gasket, it’s time to get down to the nitty-gritty and clean it. The gasket is the rubber seal around the dishwasher door that helps keep water from leaking out. Over time, food particles and grease can accumulate in this area, resulting in clogs. To get rid of any build-up, use a damp cloth or sponge to wipe down the gasket. Don’t forget to check inside for any gunk that might be hidden behind it.

If your dishwasher still isn’t draining properly, there could be an issue with the float switch. This switch senses how much water is inside the machine and shuts off when it reaches a certain level. It’s located near either the front or side of your dishwasher and looks like a plastic cylinder with a hinged arm attached. Make sure you carefully remove any debris blocking its operation before testing it out, as this may be all you need to do in order to get your appliance back in action!

To test if the float switch is working properly, manually move its arm up and down several times while monitoring if any water flows into or out of the unit. If it doesn’t move freely, then it likely needs replacing—but don’t worry: with just some simple tools and a bit of know-how, you should be able to replace it yourself without much trouble!

Inspect The Float Switch

Alright, so now on to the float switch. This is an important piece of the puzzle when it comes to figuring out what’s wrong with your dishwasher not draining properly. The float switch is located at the bottom of the unit and its purpose is to sense how full the water level is. If it gets too high, it will shut off the water supply.

So, let’s take a look at it. First, unplug your dishwasher from the power source and remove any access panels or kick plates that may be in the way. Once you’ve done that, locate the float switch and check for debris or blockages that could be preventing it from working properly. Then make sure that it’s clean and functioning correctly.

If everything looks good there, go ahead and reassemble everything back together and plug your machine back in. Try running a cycle again to see if this fixed the problem—if not, there might be something else going on that needs further investigation.

Check The Timer

Are you wondering how to solve the issue of your dishwasher not draining? Checking the timer is an important step in fixing this problem. Let’s take a look at how to do it!

First off, turn off power to the appliance and unplug it from the wall outlet. This is an essential safety precaution when working with any electrical appliances. Next, locate the timer on the control panel and remove it – usually just by taking out two screws and sliding it out. Take a closer look at the contacts behind the timer, as these are what regulate water flow into the dishwasher. If they appear corroded or burnt, they should be replaced; otherwise, simply wipe them clean with a dry cloth or cotton swab and reassemble everything.

If that doesn’t fix your issue, then it’s time to move onto inspecting the water inlet valve – but make sure to double-check that all connections are secure before proceeding!

Inspect The Water Inlet Valve

Once you’ve checked the timer, it’s time to inspect the water inlet valve. This valve is what allows water to enter your dishwasher and can be found at the bottom of your appliance. It’s important to make sure that it’s clean and not clogged up with debris, as this will prevent proper draining. Here’s how to check:

  1. Unplug the dishwasher from power supply.
  2. Access the valve by removing its cover or lower kick panel.
  3. Inspect the valve for any blockages or damage, such as rust or cracks.

If everything looks good but your dishwasher still isn’t draining, run a diagnostic test on the water inlet valve to make sure it’s functioning properly. This test should be conducted by a qualified technician who can accurately assess if there are any faulty components in need of repair or replacement. Before having a professional come out for a service call, take a few moments to review your manufacturer’s manual for instructions on how to run this test yourself. Ready to move on? Then let’s get started!

Run A Diagnostic Test

Finally, it’s time to take the bull by the horns and run a diagnostic test. The dishwasher can be a tricky piece of machinery, so doing this will provide you with some much-needed insight into what’s really going on under the hood. It’ll be worth your while in the long run!

To start, unplug the dishwasher from its power source and then remove the lower access panel. From there, use a multimeter to check for voltage coming out of the water inlet valve. If it registers zero volts—bingo!—that means that the valve is stuck and needs to be replaced. If it does show some voltage, however, then you’ll probably need to move onto inspecting your drain pump and motor next.

Testing these components requires using another type of multimeter (an ohmmeter) set to measure resistance. If you don’t have one handy or don’t feel comfortable tackling this task yourself, it might be time to consider calling in a professional at this stage.

Call A Professional

Sometimes, a situation arises that’s too much for even the most DIY-minded of us. If you find yourself facing an issue with your dishwasher that doesn’t seem to have a straightforward solution, it might be time to call in a professional.

It’s understandable to feel intimidated by this prospect — who wouldn’t want to take care of their own problems? But when it comes to repairs, some jobs are better left to the pros. And if you’re dealing with a dishwasher not draining properly, it’s probably one of those cases.

An expert technician can quickly identify the source of the issue, and provide reliable solutions for getting your appliance back up and running in no time. Don’t let yourself get bogged down with worries over taking this step; chances are you’ll be glad you did once everything is working as it should again!


Conclusion: You should now have a better understanding of what to do when your dishwasher is not draining. If the steps outlined above did not fix the issue, it may be time to call in a professional for help. A handyman can quickly diagnose the problem and recommend a course of action that will get your dishwasher back in working order as quickly as possible.

The most important thing to remember is that dishwashers are durable machines that require very little maintenance. However, if you find yourself in a situation where your dishwasher isn’t draining properly, don’t hesitate to take the necessary steps to fix the problem before calling in a professional. After all, why pay for something you can potentially fix on your own?

Finally, ask yourself this – is my dishwasher draining correctly or do I need help? If you’re still unsure after trying the steps above, then it’s best to call in an expert who can diagnose and repair any underlying issues with your machine.
