How to Clear A Dishwasher Drain Hose The Easy Way!

Want to learn how to clear a dishwasher drain hose? Well you have come to the right place. Make sure to follow the six steps below!

When your dishwasher’s plastic drain hose becomes clogged, your dishwasher won’t be able to drain. Needless to say, that’s going to cause a host of problems, and if you’re like most people, then the idea of living without a working dishwasher is far too terrible to imagine.

Thankfully, unclogging your dishwasher drain hose is easier than you might think, and there are a number of ways that you can do so without compromising your sanity. Let’s take a look at some of the most effective ways for how to clear a dishwasher drain hose! Read on for more information.

Unclogging Your Drain Hose in 6 Steps

Here are six easy steps that you should take when unclogging your dishwasher outlet hose.

Do some preparation

Before you face the draining issues head-on, you’ll want to make sure that you prepare your dishwasher first.

To do this, make sure that all of your dishes and silverware have been removed. If they’re still dirty, take the time to separate them from your other dishes so that you can get back to cleaning them after you’ve solved the issue with your washer.

We also suggest removing your dishwasher’s bottom rack to provide you with easy access to the machine.

Make sure the machine is off

Now that you’ve emptied your dishwasher of its dishes, go ahead and shut off the power running both to your dishwasher and your garbage disposal (if you have one). It’s vital that you make sure that there’s absolutely no current traveling to the machine.

We probably don’t need to remind you that water and electricity do not mix well.

Use a towel to remove dingy water

After you have fully disconnected your washing machine from its power source, you can begin removing any leftover standing water using a towel. This is not only necessary to make sure that your dishwasher is clean, but will also reduce your chances of slipping and falling on hot water while you’re working around the washer.

Check your hose

It’s now time to examine your drain hose. The drain hose is the dishwasher drain connection from the garbage disposal to the machine and is found either behind the dishwasher itself or under your sink.

In the case of the former, you are first going to need to pull your dishwasher away from the wall to access your hose.

Take the drain hose out and clean it

After you have found your drain hose, disconnect it from the machine. To do this, you’re probably going to need a pair of pliers to remove or loosen the clamp. It helps to place a shallow dish or pan to catch any water that might spill during this process.

After you’ve removed the hose, you can start cleaning all of the dirt out. Commercial de-cloggers work just fine for this, but if you’re feeling like a real MacGyver, you can make your own using a straightened coat hanger.

If you don’t discover any food debris disrupting the hose, then the problem may have nothing to do with the hose, but with the dishwasher drain itself.

Checking the dishwasher drain

Be on the lookout for a basket-shaped component at the bottom of your dishwasher. Remove it using a screwdriver and then, as you did with your drain hose, use a de-clogging agent to remove any debris that might have become lodged in the drain.

If your dishwasher is still not draining correctly, then it may be time to get in touch with a professional.

How to Know if Your Dishwasher is Clogged

There are a couple of telltale signs that let you know that your dishwasher is most definitely clogged. Here are some of the most prominent.

You’re noticing a backup of water after the washing cycle

Standing water in your machine after it has completed a dishwasher cycle means that your machine is not properly draining its water supply. This is generally caused by a backup of leftover bits of food that clog the drainage system.

Be sure to give your machine a good inspection and clean the dishwasher basket. If this does not solve the problem, then it’s likely that you are dealing with a clog in your drains.

Your dishwasher drains slowly

If you notice water pooling at the bottom of your sink or dishwasher, there may be a clog or partial clog in your kitchen’s sewer line. Be sure to clear out the potential clog as soon as you can so the problem doesn’t become more severe (and expensive).

Water from the dishwasher backs up in the sink

If you didn’t already know, your dishwasher is connected to the drainage system in your kitchen sink. If your machine is running and you notice that water starts to back up into your sink, it is likely that you’re dealing with a clogged dishwasher.

A quick way to rule out a dishwasher clog is to run your garbage disposal while your dishwasher is off. It is possible that the problem is not caused by the dishwasher, but by food particles becoming trapped in the sink.

If water still backs up into the sink after you’ve done this, then you’ll know that the problem lies with your dishwasher.

You’re hearing gurgling

Abnormal shaking, gurgling, thumping, or ‘choking’ sounds that come from your dishwasher while it’s running could indicate that there is water trying to break through a clog in your primary or secondary sewer line.

What Causes a Dishwasher Drain Hose to Become Clogged?

There are quite a few causes for a drain hose backup, and they’re particularly common for models that use a corrugated dishwasher drain hose. Let’s take a look at some of the most common.

The drain hose is clogged

Your dishwasher drains its dirty water through a hose that can be connected to your garbage disposal or kitchen sink drain. This hose can become clogged by food sludge, which subsequently causes all kinds of backups and clogs.

Cleaning your dishwasher’s drain pipe, as well as the other drain pipes beneath your sink, will get rid of the clog – if it is, in fact, the source of your machine’s drainage issues.

The filter basket is clogged

Every dishwasher uses a filter basket, fitted in the drain, to prevent chunks of food and other contaminants from entering the pipes. This basket must be cleaned regularly if you want your dishes to keep coming out clean.

If you have issues with hard water, then you can use vinegar in dishwashers and their drain baskets to remove the clogs. This will prevent the holes in the dishwasher filter basket from becoming clogged.

The sewer line is broken

Most people never consider the fact that a broken sewer line can clog a dishwasher, but a broken sewer line can actually cause a whole host of problems, including a blockage of every drain in your home.

If you find that the guest toilet, dishwasher, and shower just will not drain, be sure to contact a professional to assess your home’s sewer pipes and make sure they’re in good condition.
