The Unseen Hero of Your Hobart Dishwasher: The Pump Motor

When it comes to maintaining a clean and hygienic kitchen, a reliable dishwasher is an essential appliance. Among the many components that work together to ensure your dishes come out sparkling clean, the pump motor is often overlooked. However, this crucial part plays a vital role in the overall performance of your Hobart dishwasher. In this article, we’ll delve into the world of pump motors, exploring what they do, why they’re important, and how to maintain them to keep your dishwasher running smoothly.

What Does the Pump Motor Do?

The pump motor is responsible for circulating water and detergent through the dishwasher’s spray arms, ensuring that every dish is thoroughly cleaned. It’s a critical component that works in tandem with the dishwasher’s heating element, valves, and sensors to create the perfect cleaning environment. When the pump motor is functioning correctly, it creates a powerful suction that pulls water and debris into the dishwasher, allowing the detergent to do its job.

Why Is the Pump Motor Important?

A faulty pump motor can lead to a range of issues, from poor cleaning performance to complete breakdowns. When the pump motor is not working correctly, it can cause:

1. Poor cleaning results: Incomplete cleaning can lead to food residue and stains on your dishes, making them look dull and unappealing.
2. Increased energy consumption: A malfunctioning pump motor can cause the dishwasher to work harder, leading to increased energy consumption and higher utility bills.
3. Leaks and water damage: A faulty pump motor can cause water to leak from the dishwasher, potentially leading to water damage and costly repairs.
4. Noise and vibration: A malfunctioning pump motor can create excessive noise and vibration, making it difficult to use the dishwasher.

Common Issues with Hobart Dishwasher Pump Motors

While pump motors are designed to be durable and long-lasting, they can still develop issues over time. Some common problems that may arise include:

1. Corrosion: Mineral buildup and corrosion can occur when water and detergent residue accumulate on the pump motor’s components.
2. Wear and tear: The pump motor’s moving parts can wear out over time, reducing its effectiveness and efficiency.
3. Blockages: Food particles and debris can clog the pump motor’s filters and passages, restricting water flow and reducing cleaning performance.

How to Maintain Your Hobart Dishwasher Pump Motor

To ensure your pump motor continues to function correctly, it’s essential to perform regular maintenance tasks. Here are some tips to help you keep your pump motor in top condition:

1. Clean the filter: Regularly clean the filter to prevent blockages and ensure proper water flow.
2. Check for corrosion: Inspect the pump motor’s components for signs of corrosion and clean or replace them as needed.
3. Lubricate moving parts: Apply a small amount of lubricant to the pump motor’s moving parts to reduce wear and tear.
4. Run cleaning cycles: Run cleaning cycles on your dishwasher to remove food residue and debris that can accumulate on the pump motor’s components.
5. Check for leaks: Regularly inspect the dishwasher for signs of leaks and address any issues promptly to prevent water damage.

Troubleshooting Common Issues with Your Hobart Dishwasher Pump Motor

If you’re experiencing issues with your pump motor, it’s essential to troubleshoot the problem before calling a professional. Here are some common issues and their solutions:

1. Poor cleaning results: Check the filter for blockages and clean or replace it as needed. Ensure the detergent dispenser is functioning correctly and not clogged.
2. Leaks: Inspect the dishwasher for signs of leaks and address any issues promptly. Check the pump motor’s seals and replace them if necessary.
3. Noise and vibration: Check the pump motor’s mounting and ensure it’s securely fastened. Lubricate the moving parts to reduce noise and vibration.


The pump motor is a critical component of your Hobart dishwasher, and its proper functioning is essential for optimal cleaning performance. By understanding what the pump motor does, why it’s important, and how to maintain it, you can ensure your dishwasher continues to run smoothly and efficiently.
