How to Prime a Dishwasher for Best Cleaning Results
To prime a dishwasher, ensure it’s empty, then add detergent. Select a normal wash cycle and start the machine. Let it run for a few minutes to fill and circulate water. Cancel the cycle, allowing the dishwasher to drain. This primes the pump and readies the system for use.
Understanding Dishwasher Priming

What is Dishwasher Priming?
Priming a dishwasher is similar to preparing a pump to move water effectively. It involves ensuring that the dishwasher pump and hoses are filled with water.
Priming is crucial because a dry pump may not be able to suction water correctly, which can lead to poor cleaning results or even damage the dishwasher’s internal components.
Why is Priming Important?
For a dishwasher to clean dishes efficiently, it needs a constant flow of water. Priming helps create the necessary water pressure and ensures the pump is ready to circulate water throughout the cleaning cycle.
This step is critical for the longevity and effectiveness of your dishwasher.
When Should You Prime?
Priming is necessary when you first install a dishwasher, after a long period of disuse, or if the dishwasher has been drained for maintenance or moving. It ensures that the machine will operate as expected when it’s time to wash your dishes.
Step-by-Step Guide to Priming Your Dishwasher

Preparation for Priming
Before you begin the priming process, ensure that your dishwasher is empty. You’ll also need some dishwasher detergent. It’s best to use a detergent that is designed for your model of dishwasher for optimal results.
Priming Self-Priming Dishwashers
Some modern dishwashers come with a self-priming cycle. If yours has this feature, consult the user manual for specific instructions. Typically, you’ll need to add detergent, select the normal wash cycle, and start the machine. The dishwasher will take care of the rest.
Priming Manual Dishwashers
If your dishwasher lacks a self-priming cycle, you’ll need to do it manually. Start your dishwasher on a normal wash cycle with detergent added. After a few minutes, the machine should have filled with water. At this point, cancel the cycle to allow the dishwasher to drain, completing the priming process.
Priming Procedure Tips
For ensuring a successful priming, listen to your dishwasher as it starts. You should hear water flowing or the machine should sound like it’s actively working.
This indicates that water is being pumped as expected. Always refer to your dishwasher’s manual for specific priming instructions.
Maintenance and Troubleshooting

Regular Maintenance
To keep your dishwasher in top condition, run it regularly and perform routine inspections for any signs of wear or leaks. This will help ensure that the priming mechanism continues to work effectively.
Common Priming Issues
Problems with priming can arise from clogged filters, hoses, or a malfunctioning pump. If you notice that your dishwasher isn’t cleaning well or you don’t hear the sound of water during the start of a cycle, there may be a priming issue.
Troubleshooting Priming Problems
If your dishwasher isn’t priming correctly, check for blockages and ensure that the filters are clean. If the issue persists, consult your user manual for troubleshooting steps, which can often resolve common problems.
When to Seek Professional Help
If troubleshooting doesn’t solve the priming issue, it may be time to seek professional help. A qualified technician can diagnose and repair more complex problems that might be affecting your dishwasher’s performance.
