How to Fix a Dishwasher Not Draining

Introduction

A dishwasher not draining is a common issue that can be caused by various reasons. It can be frustrating to find a pool of dirty water in the bottom of the dishwasher after a cycle. However, with the right knowledge and tools, you can fix the problem in no time. In this article, we will discuss the steps to fix a dishwasher not draining.

Step 1: Check the Garbage Disposal

One of the most common reasons for a dishwasher not draining is a clogged garbage disposal. If your dishwasher is connected to a garbage disposal, make sure it is clear of food debris. You can do this by turning off the power to the disposal and removing any visible debris.

Step 2: Check the Drain Hose

Another reason for a dishwasher not draining is a clogged drain hose. The drain hose is located at the back of the dishwasher and can become clogged with food debris or other objects. Check the hose for any visible clogs and remove them if necessary.

Step 3: Check the Air Gap

An air gap is a device that prevents dirty water from flowing back into the dishwasher. If the air gap is clogged, it can cause the dishwasher not to drain properly. Check the air gap for any visible clogs and clean them if necessary.

Step 4: Check the Dishwasher Pump

The dishwasher pump is responsible for pumping water out of the dishwasher. If the pump is not working properly, it can cause the dishwasher not to drain. To check the pump, remove the dishwasher’s bottom rack and locate the pump. Check the pump for any visible damage or clogs and clean or replace it if necessary.

Step 5: Check the Drain Solenoid

The drain solenoid is a device that controls the dishwasher’s drain valve. If the solenoid is not working properly, it can cause the dishwasher not to drain. Check the solenoid for any visible damage and replace it if necessary.

Step 6: Check the Drain Valve

The drain valve is responsible for allowing water to flow out of the dishwasher. If the valve is clogged or damaged, it can cause the dishwasher not to drain. Check the valve for any visible clogs or damage and clean or replace it if necessary.

Step 7: Check the Float Switch

The float switch is a device that detects the water level in the dishwasher. If the switch is stuck or damaged, it can cause the dishwasher not to drain. Check the switch for any visible damage and replace it if necessary.

Step 8: Check the Drain Pump Belt

If your dishwasher has a belt-driven pump, check the belt for any visible damage or wear. A damaged or worn belt can cause the dishwasher not to drain. Replace the belt if necessary.

Step 9: Check the Timer or Control Board

If all the above steps fail, the issue may be with the dishwasher’s timer or control board. Check the timer or control board for any visible damage or malfunction and replace it if necessary.

Conclusion

Fixing a dishwasher not draining can be a daunting task, but with the right knowledge and tools, it can be done quickly and easily. By following the steps outlined in this article, you can identify and fix the issue, allowing your dishwasher to function properly again.
