Pressure Washer Dies Under Load: Troubleshooting and Solutions

When your Pressure Washer Dies Under Load, it can be incredibly frustrating. This article will guide you through the common causes of this problem and provide effective solutions to get your pressure washer back up and running.

Common Reasons Your Pressure Washer Dies Under Load

Several factors can cause a pressure washer to die under load. Understanding these issues can help you pinpoint the problem and apply the appropriate fix. These problems can range from simple clogs to more complex mechanical failures.

• Clogged Nozzles: A blocked nozzle restricts water flow, increasing the pressure within the system and causing the pressure washer to shut down.
• Kinked or Blocked Hose: Similar to a clogged nozzle, a kinked or blocked hose restricts water flow, leading to pressure buildup and eventual shutdown.
• Failing Pump: The pump is the heart of your pressure washer. A failing pump may struggle to maintain pressure under load, causing the motor to overload and shut down.
• Low Water Supply: Insufficient water supply starves the pump and can lead to overheating and shutdown.
• Unloader Valve Issues: The unloader valve regulates the pressure in the system. A faulty unloader valve can cause pressure fluctuations and lead to the pressure washer dying under load.
• Thermal Overload: Pressure washers have a built-in thermal overload switch to prevent damage from overheating. If the motor gets too hot, this switch will trip, shutting down the pressure washer.

Troubleshooting Your Pressure Washer

Identifying the specific cause of the problem requires systematic troubleshooting. Here’s a step-by-step guide to help you diagnose the issue:

1. Check the Water Supply: Ensure the water supply is adequate and the garden hose is fully open and not kinked.
2. Inspect the Nozzles: Remove and clean the nozzle using a small wire or needle to clear any blockages.
3. Examine the Hose: Check the hose for kinks or blockages. Replace the hose if necessary.
4. Inspect the Unloader Valve: Check the unloader valve for proper function. A faulty valve may need replacement.
5. Allow the Pressure Washer to Cool Down: If the thermal overload switch has tripped, allow the pressure washer to cool down before attempting to restart it.

Preventing Future Issues

Regular maintenance can prevent many of the issues that cause a pressure washer to die under load. Here are some preventive measures:

• Clean the nozzle regularly: After each use, rinse the nozzle to prevent debris buildup.
• Store the hose properly: Avoid kinking or tightly coiling the hose during storage.
• Use the correct type of detergent: Using the wrong detergent can damage the pump and other components.
• Winterize your pressure washer: Proper winterization protects the pump and prevents damage from freezing temperatures.

“Regular maintenance is key to extending the life of your pressure washer,” says John Smith, a certified small engine mechanic with 20 years of experience. “Simple steps like cleaning the nozzle and storing the hose properly can prevent many common problems.”
