What Should I Do If The Water From My Sink Drains Into My Dishwasher

How come my dishwasher is backing up in my sink?

If the water from your sink drains into your dishwasher, its probably because the dishwasher is lower than the sink. This can happen if the dishwasher has been installed incorrectly or if the house has settled.

To fix this problem, you will need to raise the dishwasher. To do this, put a level on top of the dishwasher and shim up the dishwasher until it is level. Once the dishwasher is level, the water should no longer drain into it.

What Size Is Dishwasher Waste Pipe

The waste pipe is connected to the drain pipe. As its name suggests, it carries the waste to the draining area. Thus, besides its size, you must ensure that it is robust, especially to rust.

On its size, the most recommendable diameter is ¾ inches. However, you should highly consider the pipe you are connecting with.

Additionally, you should also check the length of the waste pipe. Ideally, it should be long enough to reach the septic tank or the drainage area.

Why Does Your Dishwasher Smell Bad

This occurrence is common among appliances that are not cleaned properly. In the case of dishwashers, the bad smell comes from remnants of food and grease buildup.

The bad smell coming from your dishwasher is not permanent. An easy fix is to change the detergent you use. The one you have may not be strong enough to get rid of bits and pieces of food, as well as bad odors.

Check Your Dishwasher Drain

While it may seem like the first thing you should check, the dishwasher drain could be the problem. Removing your dishwasher racks and sticking your head inside your dishwasher to probe its drain takes a bit more effort. If after checking the air gap and checking the disposal the dishwasher still wont drain, its time to get up close and personal with the inside of your dishwasher.

Once the racks are out, get a good look at your dishwashers drain with a flashlight. If you see debris clogging the drain, clean it out. For tough clogs, you may need to bend the hook of a metal coat hanger into a small U shape that can fit farther down the drain than your finger might. Probe the drain, fishing out any other debris that may be clogging.

What Are The Most Common Problems With Dishwashers

One of the most common issues with dishwashers, apart from having a conflict with sinks, is that the dishes are not drying.

After a full cycle, you should be able to put dry dishes away. However, there are times when the drying function fails. The happens when the rinse aid dispenser is empty. The rinse aid dispenser helps dishes dry in the dishwasher.

Some dishwashers can leave white residue or spots on glassware. This is a result of hard water.

Hard water has high levels of magnesium and calcium, and it can stain glassware. The residues can be removed with your trusty vinegar solution. Add the solution to the dishwasher and run it normally.

These are just common problems with dishwashers. You may run into more issues if you are not careful in operating and maintaining your dishwasher.

Your Kitchen Sink Pipes Are Clogged

When you use the kitchen sink frequently, it is inevitable that food, gunk, grease, and hair get washed down the drain. Some of this debris will pass through the pipes without obstruction, but other bits and pieces could also get stuck. Over time, this buildup makes the opening of the pipes narrower, so its harder for water to pass through freely. As the problem worsens, the water has nowhere to go but get pushed back up the sink drain.

The sink trap is particularly vulnerable to clogging. While the sink trap is a valuable plumbing component that stops sewer gas, it does tend to accumulate buildup easily. As the buildup restricts the flow of water more and more, there comes a point when the buildup becomes significant enough. This will cause the water to back up in the kitchen sink.

Fixing the clogged kitchen sink pipes will require the knowledge and expertise of a professional plumber. The best way to prevent this problem from happening is to minimize the probability of clogs. For instance, you can place a hair catcher in your kitchen sink. This device helps to prevent hair and other particles from being washed down the sink, reducing the likelihood of clogged pipes.

    Why Is A Drainage Setup Necessary

    Once your dishwasher is done doing its primary job, it needs to send that mucky water out and in to your homes drainage system to get rid of it safely. If this is not done, or done incorrectly, that water will simply dirty up your dishes again, create a mess everywhere, possibly flood your kitchen, and the list of potential disasters goes on. Trust me, this is something you want to do and get right the first time!


    Dishwashers eject spent water with considerable force, so its important to connect them properly to the existing plumbing. On sinks with a garbage disposer installed, a connection is provided on the disposer for this purpose. But if you dont have a disposer, the plumbing can get complicated. One of the easiest methods is to replace the existing tail piece on your kitchen sink with one that has a dishwasher drain connection, known as a dishwasher branch tail piece.

  • 1.

    Place a bucket under the sink beneath the drain trap to catch leaks.

  • 2.

    Detach the large nut holding the top of the old tail piece to the sink drain outlet. The tail piece is connected either directly to the bottom of the basket strainer or to an intermediate piece attached to the strainer with a slip-joint connector, depending on the type of sink and drain arrangement. Although drain line nuts should generally be installed hand-tight, it may be necessary to use a pipe wrench or adjustable wrench to remove them.

    Kitchen Sink Draining Back Into The Dishwasher Troubleshooting And Repair

    Sink drains are the very best drains for your homes plumbing system. If there are issues together with your complete plumbing network, the signs and symptoms will in all likelihood occur in different elements of the house before they impact your kitchen sink.

    Remove And Clean The P

    This is a quick and an effective method to unclog a kitchen sink though most people hardly use it. It requires no prior plumbing experience as well.

    A P-trap is the U-bend part of your drainpipe underneath your sink. It has 2 main functions:

    • Due to its shape, it holds water at all times which acts as a barrier preventing sewer odors from coming up through the sink drain.
    • It traps potential drain clogs, preventing them from clogging the drainpipe farther away where unclogging would be more difficult.

    If your double kitchen sink is backing up into the other side, there is big chance that the clog is inside the P-trap. Removing and cleaning the P-trap will solve the problem.

If you ever need to replace the filter, you will look in the handbook for the make and model of the dishwasher to make sure you purchase the right replacement.
