Pressure Pump Troubleshooting

Pressure washer unloaders play a crucial role in maintaining optimal performance and safety of the machine. If you encounter issues with your pressure washer, such as low pressure or difficulty starting the engine, it's essential to troubleshoot and identify whether the unloader is the cause. This guide will walk you through the troubleshooting process and provide some specific recommendations for K7 style unloaders and VRT unloaders.

  1. Identifying Unloader-Related Problems: a. Low Pressure: If your pressure gauge indicates low pressure while operating the pressure washer, it is likely that the unloader is malfunctioning. b. Difficulty Starting the Engine: If you experience trouble starting the engine, try removing one outlet plug on the pressure washer. If the machine starts fine after doing so, the unloader may be at fault.

  2. Troubleshooting K7 Style Unloaders: a. Confirm the problem: Check the pressure gauge to determine if the pressure is lower than expected. If it is, it is likely that the unloader needs attention. b. Remove the unloader: Disconnect the pressure washer from the power source and remove the unloader from the machine. Make sure to follow the manufacturer's instructions for proper removal. c. Replace the unloader: Install a new unloader, ensuring it is compatible with your pressure washer model. It is recommended to replace the unloader before considering pump replacement or rebuilding, as this often resolves the issue.

  3. Troubleshooting VRT Unloaders: a. Confirm the problem: If the pressure washer's engine is difficult to start, try removing one outlet plug. If the engine starts fine after removing the plug, the unloader may be causing the problem. b. Remove the unloader: Disconnect the pressure washer from the power source and locate the VRT unloader. Follow the manufacturer's instructions to safely remove the unloader. c. Replace the unloader: Purchase a new, high-quality VRT unloader from a reliable supplier such as Cigar City Softwash Supply. Ensure the replacement unloader matches your pressure washer's specifications. d. Install the new unloader: Follow the manufacturer's instructions to correctly install the new unloader, ensuring all connections are secure.
