Detailed Overview of Power Washer Parts
1. Motor or Engine
The motor or engine is the heart of the power washer, providing the force needed to pressurize water. Sears offers electric and gas-powered models:
- Electric motors are quieter, require less maintenance, and are suitable for light to medium tasks.
- Gas engines deliver higher power, ideal for heavy-duty cleaning.
Common issues include motor failure, overheating, or electrical problems, often requiring replacement or repair of the motor assembly.
2. Pump
The pump pressurizes water and is a critical component. Sears power washer pumps are typically axial or triplex plunger types:
- Axial piston pumps are common in lower-end models.
- Triplex pumps are more durable and suited for frequent, heavy-duty use.
Parts associated with the pump include:
- Pump head
- Pistons or plungers
- Pump seals and valves
Regular maintenance involves replacing worn seals or pistons to prevent leaks and loss of pressure.
3. High-Pressure Hose
The hose carries pressurized water from the pump to the spray gun. It needs to withstand high pressure and temperature.
Common problems:
- Cracks or leaks
- Kinks or damage from abrasion
- Connection failures
Replacement hoses are readily available, but it’s important to select the correct length and diameter.
4. Spray Gun and Wand
The spray gun controls water flow, while the wand directs the spray. These parts are ergonomic and designed for ease of use.
Signs of wear:
- Leaking connections
- Trigger failure
- Cracks or breaks
Genuine Sears replacement spray guns and wands ensure compatibility and safety.
5. Nozzles
Nozzles determine spray pattern and pressure. Sears power washers often come with multiple nozzles, including:
- 0°, 15°, 25°, 40°, and soap nozzle
Key points:
- Using the correct nozzle prevents damage.
- Nozzles can clog or wear out, requiring cleaning or replacement.
6. Unloader Valve
This component protects the pump by redirecting excess water pressure back to the inlet when the spray gun is closed.
Troubleshooting:
- Leaking unloader valve
- Loss of pressure
- Difficulty adjusting pressure
Replacement unloader valves are available to restore proper operation.
7. Thermal Relief Valve
Prevents the pump from overheating by releasing excess heat and pressure. If faulty, it may cause pressure buildup or leaks.
8. Water Inlet Filter
Filters debris from the water supply, protecting internal components.
Maintenance tip:
- Regularly clean or replace filters to prevent clogs and damage.
9. Detergent Injector
Allows for soap or cleaning solutions to be applied during washing.
Problems:
- Clogging
- Failure to draw detergent
Replacement parts include injector nozzles and check valves.
10. Power Cord (Electric Models)
Ensures safe electrical operation. Damaged cords pose safety hazards.
