Setup and Installation
This section outlines the general steps for replacing the control head. Specific procedures may vary slightly depending on your pressure washer model.
- Preparation: Ensure the pressure washer is disconnected from power and water. Release all residual pressure.
- Access the Control Head: Depending on your pressure washer model, you may need to remove the outer casing or other components to gain access to the existing control head.
- Disconnect Connections: Carefully disconnect all hoses, wires, and other attachments from the old control head. Note their positions for reassembly.
- Remove Old Control Head: Unfasten any screws, clamps, or retaining clips holding the old control head in place. Gently remove it from the pump assembly.
- Inspect and Clean: Before installing the new control head, inspect the pump housing and surrounding areas for any debris or damage. Clean as necessary.
- Install New Control Head: Position the new Karcher Control Head (Model 90013610 / 9.001-361.0) into the pump assembly. Ensure it seats correctly and securely.
- Secure the Part: Fasten the new control head using the original screws, clamps, or retaining clips. Do not overtighten.
- Reconnect Connections: Reattach all hoses, wires, and other components to the new control head in their original positions. Ensure all connections are tight and secure to prevent leaks.
- Reassemble Casing: If you removed any casing or other components, reassemble them carefully.
Operating (Post-Installation)
After successful installation of the control head, follow these steps to test your pressure washer:
- Connect Water Supply: Connect the pressure washer to a suitable water source.
- Bleed Air: Turn on the water supply and allow water to flow through the system (without turning on the motor) until all air is purged from the hose and pump. This helps prevent air pockets from damaging the pump.
- Connect Power: Plug the pressure washer into a grounded electrical outlet.
- Test Operation: Turn on the pressure washer and test its operation. Check for proper water flow, pressure, and any leaks around the newly installed control head.
- Monitor Performance: During initial use, monitor the pressure washer's performance to ensure the control head is functioning correctly.
Maintenance
Proper maintenance extends the life of your pressure washer and its components.
- Regular Inspection: Periodically inspect the control head and its connections for signs of wear, cracks, or leaks.
- Clean Connections: Keep all connections clean and free of debris.
- Winterization: If storing the pressure washer in freezing temperatures, ensure the pump and control head are properly winterized according to your pressure washer's main manual to prevent damage from freezing water.
Troubleshooting
If you encounter issues after installing the control head, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water leaks from control head connections. | Loose connections, damaged O-rings/seals, incorrect installation. | Tighten connections. Inspect and replace O-rings/seals if damaged. Re-install carefully. |
| No pressure or low pressure. | Air in the system, clogged inlet filter, faulty unloader valve (part of control head). | Bleed air from the system. Check and clean inlet filter. If unloader valve is faulty, the control head may need replacement or professional service. |
| Pressure washer cycles on/off frequently. | Internal leak, faulty pressure switch (part of control head). | Check for external leaks. If no external leaks, the issue may be internal to the control head, requiring professional inspection. |
If troubleshooting steps do not resolve the issue, contact Karcher customer support or a certified service center.
