Product Information
Full details
This Karcher Pressure Washer Capacitor is for Karcher pressure washer owners experiencing starting issues or motor problems. Its key benefit is restoring your pressure washer's motor functionality, ensuring consistent power. A potential caveat is that this is a specific replacement part, requiring confirmation of compatibility with your exact model. This capacitor features a durable metalized polypropylene film construction with a plastic housing, designed for 50-60 Hz frequencies, offering a precise 20 microfarad (uF) capacity with a tolerance of ± 5%.

FAQs
What does a 20uF rating mean?
The 'uF' stands for microfarad, which is a unit of electrical capacitance. A 20uF rating indicates the capacitor's ability to store electrical charge, essential for providing the initial 'kick' to start the pressure washer motor.
What is the voltage rating (400V) for?
The 400V rating specifies the maximum voltage the capacitor can safely withstand without damage. It must be equal to or greater than the voltage of your pressure washer's motor circuit.
How do I know if my Karcher capacitor needs replacing?
Common signs include the motor humming but not starting, starting very slowly, or cutting out intermittently. If your pressure washer experiences these symptoms, the capacitor is a likely culprit.
Can I use a capacitor with a different uF rating?
It is strongly recommended to use a capacitor with the exact same uF rating as the original. Using a different rating can lead to improper motor function, reduced efficiency, or damage to the motor or capacitor.
Can I use a capacitor with a higher voltage rating?
Yes, you can generally use a capacitor with a higher voltage rating (e.g., 450V instead of 400V) as long as the uF rating is the same. A higher voltage rating simply means it can handle more electrical pressure.
Is this capacitor suitable for all Karcher pressure washers?
This capacitor (9.085-023.0) is designed as a replacement part for specific Karcher pressure washer models. You must verify that your pressure washer requires a 20uF, 400V capacitor before purchasing.
What are the physical dimensions of this capacitor?
The capacitor has a length of 88mm and features a plastic housing.
Troubleshooting
Pressure washer motor hums but does not start.
This is a common symptom of a failed capacitor. Replace the existing capacitor with this 20uF, 400V Karcher replacement.
Pressure washer motor starts weakly or struggles to maintain power.
A degraded capacitor may cause this. Replacing it with a new, correctly rated capacitor like this one should resolve the issue.
New capacitor installed, but the motor still does not start.
Double-check that the capacitor is the correct rating (20uF, 400V) and that the wires are connected securely to the correct terminals. The issue might lie with another component, such as the motor itself or the power switch.
Capacitor does not fit in the designated space.
Verify the dimensions of the capacitor against the space available in your pressure washer. While this capacitor is 88mm long, ensure no other physical obstructions prevent installation.

Setup, Compatibility & Care
Compatibility:
This capacitor (part number 9.085-023.0) is designed as a replacement for specific Karcher pressure washer models. Always verify that your pressure washer's original capacitor has the same specifications: 20uF, 400V, and fits within the allocated space (88mm length).
Setup (Installation):
Disclaimer: Replacing electrical components involves risk. If you are not comfortable working with electrical systems, consult a qualified technician or refer to your pressure washer's service manual.
- Disconnect Power: Ensure the pressure washer is unplugged from the power source and any connected hoses are depressurized.
- Access the Capacitor: Open the housing of your Karcher pressure washer to locate the capacitor. This usually involves removing screws from the casing.
- Note Connections: Carefully observe or photograph how the wires are connected to the terminals of the old capacitor.
- Remove Old Capacitor: Disconnect the wires from the old capacitor. It may be secured by a bracket; remove it.
- Install New Capacitor: Mount the new 20uF, 400V capacitor in the same location. Connect the wires to the corresponding terminals.
- Secure and Reassemble: Reassemble the pressure washer housing, ensuring all screws are tightened.
- Test: Plug in the pressure washer and test its operation.
Care:
Capacitors are generally maintenance-free. However, ensure the area around the capacitor within the pressure washer remains clean and free of debris to prevent overheating. Avoid exposing the unit to excessive moisture.
