Is Your Hobart Dishwasher Pump Motor Acting Up? Here’s What You Need to Know

If you own a Hobart dishwasher, you know how essential it is to keep all its components in perfect working condition. One of the key components that can cause major headaches when it malfunctions is the pump motor. In this article, we will discuss the common issues that can occur with a Hobart dishwasher pump motor and how you can troubleshoot them.

Understanding the Hobart Dishwasher Pump Motor

The pump motor is responsible for moving the water within the dishwasher and creating the necessary force to spray it onto your dishes. It plays a crucial role in the dishwasher’s overall cleaning performance. Without a properly functioning pump motor, your dishes may come out dirty and unsanitary.

Common Issues with the Hobart Dishwasher Pump Motor

1. Noisy Operation:
If you notice your dishwasher making loud grinding or squealing noises when running, it may be an indication that the pump motor is malfunctioning. The source of the noise could be a worn-out bearing or a loose impeller. Both of these issues require immediate attention to prevent further damage to the motor.

2. Weak Spray:
If the water spray inside your dishwasher seems weak, it could be a sign of a faulty pump motor. A weak spray can result from a clogged pump or a motor that is not generating enough force. You can try cleaning the pump and removing any debris that may be obstructing its operation. If the problem persists, it may be necessary to replace the pump motor altogether.

3. Leaking Water:
A leaking dishwasher is never a good sign. A malfunctioning pump motor can cause water leakage due to worn-out seals or damaged pump housing. If you notice water pooling under or around your dishwasher, it is crucial to address the issue promptly to avoid further damage to your kitchen floor or cabinets.

Troubleshooting and Maintenance Tips

1. Regular Cleaning:
To prevent clogs and keep your pump motor running smoothly, it is essential to clean your dishwasher regularly. Remove any food particles or debris from the dishwasher tub and filters. Run a dishwasher cleaning cycle with vinegar or a dishwasher cleaner to ensure all internal components are free from residue.

2. Check the Impeller:
The impeller is a critical component of the pump motor responsible for creating the water spray. If the impeller is damaged or loose, it can affect the dishwasher’s cleaning performance. Inspect the impeller for any signs of wear or debris accumulation. If necessary, tighten or replace the impeller.

3. Inspect Seals and Gaskets:
Worn-out seals and gaskets can cause water leakage. Check them regularly for signs of damage or deterioration. If you notice any issues, replace the faulty seals or gaskets promptly to prevent further leakage.

4. Seek Professional Help:
If you have tried troubleshooting the issues with your Hobart dishwasher pump motor and the problems persist, it may be time to call in a professional technician. They have the expertise and knowledge to diagnose and repair complex motor issues accurately.


Your Hobart dishwasher’s pump motor is a vital component that ensures proper cleaning performance. By understanding common issues and implementing regular maintenance, you can keep your dishwasher running smoothly and extend its lifespan. Remember to address any problems promptly to avoid costly repairs or replacements. So, keep an eye out for any unusual noises, weak sprays, or water leakage, and take action to resolve these issues proactively. Happy dishwashing!
