Let Your Maytag Dishwasher Tell You The Problem

Dishwasher Not Draining | How to Fix a Dishwasher That Won’t Drain in 4 Steps

In this age of smart machines, it is no surprise that your Maytag dishwasher may be able to tell you the problem. Like many other smart appliances, if your Maytag dishwasher senses a problem, an error code will flash on the control panel.

On most Maytag dishwashers, the code indicates by flashing the Clean button in a unique pattern. If the clean light is flashing, there is an error code with your dishwasher. The error code has two parts. First, the machine will flash the function code. After a two-second pause, the problem code will flash.

For example, the Clean button flashes four times, pauses for two seconds, and then flashes three times. This code represents error code 4-3 or a fault in the communications between the electronic control board and the circulating pump.

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.’

Check The Pump Drain Impellers

After wastewater goes through the filter, it is sent to the drain hose by a drain pump located at the bottom of the dishwasher.

The drain pump just like other pumps has impellers which spin at a high speed and in the process force water out of the dishwasher. Sometimes, product labels, brush bristles and other tiny objects can escape through the filter and jam the impellers.

When a drain pump impellers are jammed, they cannot spin and when they donât spin it means wastewater cannot drain out of the dishwasher. This is could be the reason you have standing water at the bottom of your dishwasher.

To access your drain pump impellers, you will need to have removed your dishwasher filter. Inside the filter sump , you will see a small plastic cover. That is the cover that conceals the drain pump impellers.

Use a flathead screwdriver or just your hand to remove the cover to reveal the impellers. You may need a flashlight to properly see them.

Check if there is anything jamming the impellers and preventing them from spinning. Fish the clogs out and try to manually spin the impellers using the screwdriver.

When the impellers start to spin freely, put back the cover and the filter. Again, you can test the dishwasher at this time or wait until you have checked other areas.

If your dishwasher model does not have the cover near the filter, another way to check the impellers is by disconnecting the drain hose from the drain pump as shown in the point below.

Replace The Water Inlet Valve

The water inlet valve on your dishwasher allows water to enter. If it is damaged, the water will not flow properly.

If this happens, your dishwasher will not drain and your water will overflow.

To find out if this valve is damaged, look at the bottom of the dishwasher cabinet. There is a hole where the water enters the dishwasher.

If the hole is clogged, it will make it difficult for the water to flow through the valve.

If you see a leak in the valve, clean it with a sponge or toothbrush.

Why Is There Standing Water In The Bottom Of My Dishwasher

Your dishwasher drains through a drain hose which is connected to the garbage disposal or directly to the kitchen sink drain line. The sink, garbage disposal and dishwasher therefore share the same drain line.

If you notice water at the bottom of your dishwasher, the problem could be within the dishwasher or caused by a clogged garbage disposal or sink drain line.

Standing water at the bottom of the dishwasher is a sign that it is not draining. This is often caused by a clogged filter or drain hose, or jammed drain pump impellers. It could also be caused by a kinked or poorly installed drain hose or a clogged garbage disposal/sink drain line.

If you have a new dishwasher that is not draining, it is very possible that the garbage disposal knockout plug was not removed during installation of the dishwasher. Disconnect the drain hose from the garbage disposal and knock out the plug with a hammer and punch/screwdriver.

To fix a dishwasher that is not draining, start by soaking up the standing water using a sponge. Check if the filter is clogged or the drain pump impellers are jammed. Disconnect the drain hose and blow air or snake it. If the problems persists remove and clean the P-trap then flush the drain line using baking soda and vinegar solution.

Remember that if your garbage disposal or sink drain line is clogged, draining the sink will have water backing up into your dishwasher unless you have an air gap.

Theres A Kink Or A Clog In The Drain Hose


If your drainage hose is clogged by greases or food pieces, this will keep water from draining from your dishwasher too. This can be caused by kinks, which can be cause by something heavy pressing against the hose. Usually, you can straighten these out yourself. Other times, you may need to replace the hose, especially since after a hose kinks, it tends to kink again in the same spot. Some people can replace drain hoses themselves others will have to call a plumber to do it for them.

Other Types Of Blockage

If your dishwasher still isnt draining after ensuring the filter and sump are clear then there could be a blockage elsewhere.

The dishwasher waste pipe is a good place to check next and the easiest place to get access is where it connects to the pipework under your kitchen sink.

Its unlikely that any large pieces of debris have managed to find their way down the outlet, but as the water leaving the dishwasher cools down any grease or fat traveling along the pipe can begin to solidify and cause a blockage.

Before disconnecting anything its worth giving the hose a squeeze and a wiggle to see if you can break up any solids, and then running the dishwasher on its hottest program to wash away any remnants.

If the blockage is too stubborn to be shifted by the aforementioned squeeze and wiggle then the next step is to disconnect the waste pipe in order to find and clear the blockage .

As with filter blockages, you can avoid the outlet from becoming blocked in the future by regularly running the dishwasher on a hot washing cycle which will help clear away any residue buildup.

The Problem: The Dishwasher Is Full Of Suds

Homeowners who recently installed a new dishwasher may not be aware that there are specific requirements for using that machine. Among them is that you cannot use any detergent you like.

Theres a reason why dishwasher soap is a thing.

According to The Spruce, regular liquid hand soap, detergent, and even liquid dish soap are not supposed to be used inside dishwashers because they produce suds and lots of them. Too many suds will cause clogging inside the dishwasher. On top of that, the suds are also likely to overflow, causing a mess in your kitchen.

The only real upside here is that youll know the reason why your dishwasher didnt drain right away due to the presence of the suds.

If Your Dishwasher Isnt Draining Try The Following:

Check the pump seal.

If theres just a teensy bit of water in the bottom of your dishwasher, you dont need to worry. You need a little bit of water to remain in the bottom to make sure the pump seal remains moist.

Check the dishwasher door.

If its not closed all the way and latched, the dishwasher wont finish draining. Try closing the door, latching it, and running the dishwasher again.

Check the cycle.

If the cycle was interrupted, the dishwasher might not have drained. Look for a cancel/drain button or a way to reset the dishwasher. If you don’t see a button clearly labeled on the dishwasher dash, go online and google your dishwasher’s make and model to see if you need to press a combination of buttons to make it drain.

Check the electrical source.

Many dishwashers are plugged into an outlet that is controlled by an electrical switch. Make sure you didnt accidentally turn off the electrical source mid-cycle. The switch is often next to your garbage disposal switch and can be easily switched off without you realizing you’ve cut the power to your dishwasher.

Check your dishwasher drain hose.

Your drain hose is probably connected to your garbage disposal, which means you could be experiencing issues with the disposal or the drain hose. Check to see if:

  • The drain hose is kinked, preventing drainage
  • The drain hose is clogged
  • The knockout plug is still in place and needs to be removed
  • The drain hose is hanging down or is too long

You may need a new drain hose.

Check The Sink’s Air Gap Cylinder

An air gap cylinder keeps water flowing in the right direction during the dishwashers cycles. It also prevents wastewater from backing up into the dishwasher. It should be located behind the sink and near the dishwasher outlet hose.

Check the air gap cylinder to make the inside is clear. If you notice any buildup, clean it out and make sure its tightly secured.

Let’s take a moment to sum up the situation You can hear the dishwasher’s drain pump running when you advance the dishwasher to drain, and you have eliminated the possibility of a clog in the drain hoses with a shop vac or some other method. How could the pump keep your dishwasher from not draining?

Examine The Water Level:

The dishwasher uses water to clean dishes and the water is stored in a tank. Before using the dishwasher, make sure the tank is at least two-thirds full of water.

The dishwasher may not drain completely if the water level is too low.

To check the water level, look inside the dishwasher cabinet under the door. Look for an indicator light or a small tube that will show the water level.

If you see that the water level is too low, it will be hard for the dishwasher to clean your dishes.

So, you will need to add enough water to reach the required level.
