Overview of Craftsman Pressure Washer Components
A typical Craftsman pressure washer consists of several major components, each with specific functions. These parts work together to generate high-pressure water streams used for cleaning surfaces such as driveways, decks, vehicles, and more.
Below is an overview of the main parts involved:
1. Motor or Engine
The power source of the pressure washer, available as electric motors or gas engines, providing the necessary energy to pump water at high pressure.
2. Pump Assembly
The core component responsible for pressurizing water. It typically consists of pistons, cylinders, and valves.
3. High-Pressure Hose
Connects the pump to the spray gun, designed to withstand high pressure and prevent leaks.
4. Spray Gun and Wand
The handle and extension wand through which water is expelled. The spray gun includes a trigger mechanism to control water flow.
5. Nozzles
Attach to the wand to control the spray pattern and pressure, available in various angles (e.g., 0°, 15°, 25°, 40°).
6. Unloader Valve
Regulates water pressure and redirects water flow when the trigger is not engaged, protecting the pump.
7. Fuel System (Gas-powered models)
Includes fuel tank, carburetor, and fuel lines.
8. Water Inlet Filter
Prevents debris from entering the pump and damaging internal components.
9. Pressure Regulator
Adjusts and maintains consistent pressure output.
10. Frame and Handles
Provide structural support and mobility.
Interpreting a Craftsman Pressure Washer Parts Diagram
A parts diagram is usually a schematic illustration showing all components with labels and reference numbers. These diagrams are often accompanied by a parts list that details each part's name, number, and specifications.
Steps for reading a parts diagram:
1. Identify the Section: Diagrams are often segmented into sections such as pump, motor, hose, etc.
2. Match Reference Numbers: Each part has a number that corresponds to the parts list.
3. Understand the Assembly: Follow the diagram to see how parts connect and fit together.
4. Note Part Specifications: Pay attention to size, model numbers, and compatibility for replacements.
For example, the pump assembly may be labeled as part 10 in the diagram, with an accompanying list providing its part number, description, and compatible models.
Key Components in a Craftsman Pressure Washer Diagram
Let's delve into some of the critical components often highlighted in the parts diagram:
1. Pump
- Types: Axial cam, triplex, or wobble pumps.

4. Unloader Valve
- Function: Prevents pressure buildup; redirects water flow.
- Troubleshooting: Sticking or leaking indicates replacement needs.
5. Thermal Relief Valve
- Purpose: Protects the pump from overheating.
- Operation: Opens when temperature exceeds safe limits.
6. Fuel System Components (for gas models)
- Fuel Tank: Stores fuel.
- Carburetor: Mixes air and fuel.
- Fuel Lines: Connect components; susceptible to leaks.
Maintenance and Troubleshooting Using the Parts Diagram
A well-understood parts diagram allows for efficient maintenance routines and troubleshooting. Here are some common scenarios:
Scenario 1: Pressure Loss
- Possible causes: Worn pump seals, clogged nozzles, or damaged hoses.
- Solution: Use the diagram to locate the pump and inspect seals, replace nozzles, or check hoses.
Scenario 2: Leaking Water
- Possible causes: Cracked hoses, faulty fittings, or damaged pump seals.
- Solution: Identify leak points on the diagram, then replace damaged parts.
Scenario 3: Engine or Motor Issues (Gas models)
- Possible causes: Dirty carburetor, faulty spark plug, or fuel issues.
- Solution: Use the diagram to locate engine components and perform cleaning or replacements.
Scenario 4: Nozzle Clogs
- Solution: Remove and clean or replace the nozzle, refer to the diagram for its location.
Ordering Replacement Parts
When ordering parts based on the diagram, ensure you have:
- The model number of your Craftsman pressure washer.
- The part number or reference number from the diagram.
- The specific description (e.g., "high-pressure hose 25 ft.," "triplex pump assembly").
Many parts are available through Craftsman authorized dealers, online retailers, or local hardware stores.
