If your dishwasher not draining properly, you may see water at the bottom of the tub. Before you call a repair service, there are a few things you can do to clear it.
Note: Before you do any work on your dishwasher, make sure that it’s switched off.
Here are 7 Steps to follow if your Dishwasher not draining
Step 1: Check the Plumbing Connection
Check drain hose clamp and drain valve components that help ensure everything is running smoothly. Replace any parts that show any signs of damage.
Step 2: Check the Garbage Disposal
The dishwasher drain hose connects to the disposal. If your garbage disposal is clogged, your dishwasher won’t drain properly as there is less space for the dishwasher water to go. Run hot water down the disposal and running the disposal. Run the disposer thoroughly with plenty of hot water flowing to clear it out.
Step 3: Check the Drain Hose
Check that the drain hose is securely connected to the garbage disposal and use a rag to clear any dirt. Look for any kinks in the hose and straighten them, a kinked drain hose could stop the waste water from draining away.
To check for a clog, disconnect the drain hose from the pump and try to blow through the hose to make sure it’s clear. Reattach the hose before you start your dishwasher and make sure the hose seal is tight.
Step 4: Check the Air Gap
You can find the air gap above the sink. It will look like a small cylindrical fixture mounted on the back edge of the kitchen sink. It is designed to flow water from the faucet into the sink and prevents drain water from siphoning back into the faucet.
Remove the air gap cap and clean any build up. Disconnect and check the hose that runs from the nipple on the bottom of the air gap to the garbage disposal and make sure that it is not clogged.
Step 5: Check the Filter
You can also check the dishwashers filter to ensure debris isn’t stopping the water flow. To find out the filter, look at the bottom of the tub. The filter is the place where food particles get caught. If your filter is removable, remove the filter at the bottom of your dishwasher and clean it in the warm water by using soft toothbrush and dishwashing soap. Fix the filter back into the dishwasher once the filter is cleaned out.

Step 6: Check the Valve
Some dishwashers come with a valve bracket, a valve has to open in order for the water to drain out of the dishwasher. Check the drain valve and its solenoid (The valve is controlled by a solenoid.). To test the valve, push on the valve bracket to make sure it moves freely and isn’t frozen. If need be, replace them.
Step 7: Clean the Drain Basket
The drain basket is found at the bottom of your dishwasher, to check if it’s been clogged by pieces of food or detergent. Remove any debris and clean the Drain Basket.
Clean the Drain basket with Baking Soda and Vinegar. Pour the Soda and Vinegar down the drain and let is set for 10 minutes. Pour some boiling water down to flush it through.
if still your dishwasher not draining properly, then it’s time to call in a professional.
Note : Always make sure that you’re using the right type of dish detergent to prevent the dishwasher from draining.
