You’ve just finished a long day, and the last thing you want to deal with is a dishwasher filled with standing water. It’s frustrating, right? Well, don’t worry – you’re not alone. Dishwashers can sometimes have issues with draining properly, leaving water sitting at the bottom. In this article, I’ll walk you through the exact steps to drain your dishwasher and fix any issues that might be causing the standing water. Let’s get that dishwasher running smoothly again!
Check for Blockages in the Drain Hose
The first thing you need to do is check for any blockages in the dishwasher’s drain hose. This hose is responsible for carrying wastewater from the dishwasher to the drain, so if it’s clogged, your dishwasher can’t drain properly. Blockages are common, and they can be caused by food particles, grease, soap scum, or even small debris.
Inspect the Hose for Visible Blockages
Before you start disassembling anything, take a look at the hose. The drain hose is usually located at the bottom of the dishwasher, connected to both the dishwasher and the drain. You might need to remove the lower rack to get a better view of the hose. Sometimes, you can spot food particles or debris that have accumulated in the hose. If you notice anything blocking the hose, it’s time to clean it.
Detach and Clean the Hose
To remove any blockages, you’ll need to detach the drain hose from the dishwasher. Start by using a wrench or pliers to loosen the clamp that holds the hose in place. Once the hose is free, check both ends of the hose for any visible obstructions. If you can, run some warm water through the hose to see if it flows freely. If there’s a clog, try pushing it out with a long, flexible tool like a plumbing snake or use a bottle brush to scrub the inside.
Reattach the Hose and Test It
Once you’ve cleaned the hose, reattach it securely to both the dishwasher and the drain. Tighten the hose clamp to ensure it’s sealed properly. Once everything is reconnected, run a short drain cycle to see if the water drains properly. If it does, you’ve likely solved the issue! If not, keep reading – there are more potential causes.
Inspect the Sink Drain and Air Gap
Sometimes, the problem isn’t with the dishwasher itself but with the plumbing connected to it. The dishwasher typically drains into the same plumbing system as your sink, so if there’s an issue with the sink drain, it can prevent the dishwasher from draining. A common problem is a clogged sink drain or air gap, both of which can lead to standing water in the dishwasher.
Check the Sink Drain for Clogs
If your dishwasher and sink share a drain, start by checking the sink for clogs. If the sink is also draining slowly or not at all, there may be a blockage in the shared drain pipe. You can clear minor clogs with a plunger or a drain snake. If the clog is deep within the drain pipe, you may need to call a plumber to clear the line.
Examine the Air Gap
Many dishwashers have an air gap installed to prevent backflow from the sink drain into the dishwasher. This small device is usually located behind the sink, near the faucet. It helps ensure that water flows in the right direction and prevents contamination. If the air gap is clogged, it can block the dishwasher’s ability to drain properly.
To clean the air gap, remove the cap and check for any debris or buildup inside. You can clean it by using a brush or by flushing it out with warm water. Once it’s clear, replace the cap, and test your dishwasher by running a short drain cycle.
Clean the Sink Disposal (If Applicable)
If your dishwasher is connected to a garbage disposal, check the disposal for any blockages. Sometimes, a clog in the disposal can affect the dishwasher’s drainage. If your disposal hasn’t been cleaned in a while, you can run it with some ice cubes and a small amount of vinegar to help clear out any debris.
Use a Wet/Dry Vacuum to Remove Standing Water
If the standing water is still in the bottom of the dishwasher after checking the hose and plumbing, don’t worry. You can use a wet/dry vacuum to suck out the remaining water. This will help you remove any water left in the tub, so you can troubleshoot further or clean without making a mess.
Prepare Your Vacuum
Before you begin, make sure you have a wet/dry vacuum available. These vacuums are specifically designed to handle liquids, so they’re ideal for this job. If you don’t have one, you can usually rent one from a hardware store.
Suck Up the Water
Position the vacuum hose inside the dishwasher, aiming for the area with standing water. Turn on the vacuum and let it suck up the water. Depending on how much water is in the dishwasher, it may take a few minutes to remove it completely. Once the majority of the water is gone, take a look inside the dishwasher to see if there’s any remaining debris or gunk that could be causing drainage issues.
Clean the Vacuum Hose
After you’ve removed the water, it’s a good idea to clean the vacuum hose. Dishwater can leave behind a sticky residue that could clog the vacuum hose or affect its performance. Simply rinse the hose with warm water to remove any leftover debris.
Check the Dishwasher Drain Pump
If the dishwasher is still not draining properly, the problem might be with the drain pump. The drain pump is responsible for pumping the water out of the dishwasher and into the drain. If this part is malfunctioning, it can cause standing water to accumulate.
Locate the Drain Pump
The drain pump is usually located at the bottom of the dishwasher, beneath the filter and spray arms. To access it, you may need to remove the lower rack, spray arms, and filter. Depending on the model of your dishwasher, you might also need to remove the front panel to reach the pump.
Inspect the Pump for Blockages
Once you’ve located the pump, visually inspect it for any visible blockages. Small objects, food debris, or hard water deposits can sometimes clog the pump, preventing it from working properly. If you find any debris, carefully remove it.
Test the Pump’s Function
To test if the drain pump is working, you can run a cycle while listening for the sound of the pump engaging. If you don’t hear the pump working or if it sounds weak, it may be time to replace the pump. A malfunctioning pump can be difficult to fix on your own, so you might need to call a professional appliance repair technician.
Run a Drain Cycle and Test
After completing all these steps, it’s time to run a drain cycle to see if the issue is resolved. Set the dishwasher to a short or quick drain cycle, and watch carefully to see if the water drains as it should. If everything is working correctly, the standing water should be gone, and your dishwasher should be back to normal.
I hope this guide helps you get rid of the standing water in your dishwasher and restore it to full working order. Remember, the key is to check for clogs, inspect the plumbing, and ensure all parts are functioning as they should. If you continue to have issues, don’t hesitate to contact a professional for assistance.
