If you own an Excell pressure washer and notice that the pump is not working properly, you may need to rebuild it. Over time, the pump can wear out or become clogged, resulting in decreased performance or complete failure. Rebuilding the pump can help restore it to its original condition and ensure that your pressure washer continues to operate efficiently.

Before beginning the rebuild process, it’s important to gather all the necessary tools and parts. You will need basic hand tools such as wrenches and pliers, as well as a rebuild kit specifically designed for your Excell pressure washer pump. This kit typically includes replacement seals, valves, and other components necessary for rebuilding the pump.

Start by disconnecting the pressure washer from its power source and relieving any pressure that may be in the system. Then, remove the pump from the pressure washer and place it in a clean and well-lit workspace. Take note of the orientation and arrangement of the pump components, as this will be helpful during reassembly. It may also be helpful to take pictures or make diagrams to assist in the process.

Next, carefully disassemble the pump, keeping track of each component you remove. Inspect each part for signs of wear, damage, or debris build-up. Clean any dirty or clogged parts using a mild detergent or solvent, and replace any damaged or worn-out components with the new ones from the rebuild kit. Be sure to follow the instructions provided with the kit to ensure proper installation.

Once all the necessary components have been replaced, reassemble the pump in the reverse order of disassembly. Take care to align each piece correctly and tighten all fasteners securely. Once reassembled, test the pump by reconnecting it to the pressure washer and powering it up. Check for any leaks or abnormal noises that may indicate further issues. If everything appears to be in order, you can now enjoy the improved performance of your rebuilt Excell pressure washer pump!

Troubleshooting Common Issues with an Excell Pressure Washer Pump

If you are experiencing problems with your Excell pressure washer pump, there are a few common issues that you can troubleshoot before considering a complete rebuild. By identifying and resolving these issues, you can save time and money on repairs.

  • Lack of Pressure: If your pressure washer pump is not generating enough pressure, it could be due to a clogged nozzle, a worn nozzle tip, or a blocked water inlet. Check the nozzle and tip for any obstructions and clean or replace them as necessary. Additionally, inspect the water inlet screen for debris and clean it if needed.
  • Leaking Water: A leaking pump is a common problem and can be caused by a variety of issues. Check the pump’s seals, O-rings, and gaskets for any damage or wear. Replace any faulty components to stop the leaks. Also, inspect the pressure hose and connections for any leaks or loose fittings.
  • Irregular Pressure: If your pressure washer pump is experiencing inconsistent pressure, it could be due to air in the system. Check the oil level in the pump and ensure it is filled to the proper level. Bleed any air from the system by running the pressure washer with the trigger pulled, or by following the manufacturer’s instructions.
  • Noisy Operation: Unusual noise coming from the pump could indicate a problem. It may be due to a loose or worn belt, a damaged or misaligned pump component, or insufficient oil in the pump. Inspect the pump for any loose or damaged parts, tighten any loose belts, and add oil if necessary.
  • Pump Not Turning On: If your pump is not turning on at all, check the power supply and make sure it is connected properly. Test the power outlet with another device to ensure it is functioning properly. If the power supply is fine, it could be an issue with the pump’s motor or internal components. In this case, it may require professional repair or replacement.

By troubleshooting these common issues with your Excell pressure washer pump, you can often resolve the problem without the need for a complete rebuild. However, if the issues persist or become more severe, it may be necessary to disassemble and rebuild the pump to restore it to optimal working condition.
