Repairing a pressure washer involves diagnosing the issue and taking steps to resolve it. Here's a guide to help you troubleshoot and repair common problems:
1. Problem: Pressure Washer Won't Start
Check the fuel system (for gas models):
Ensure the fuel tank is full and the fuel is fresh.
Check for clogged fuel lines or a dirty carburetor.
Inspect the spark plug and replace it if worn.
Check the power supply (for electric models):
Verify the outlet is working and the extension cord is rated for the pressure washer.
Inspect the power cord and reset the GFCI plug.
2. Problem: Low or Inconsistent Pressure
Inspect the water supply:
Ensure there is sufficient water flow and pressure from the source.
Check the inlet filter for debris.
Check for leaks:
Examine all hoses, connections, and the pump for leaks.
Replace worn or damaged O-rings.
Clean or replace the nozzle:
A clogged nozzle can reduce pressure. Clean it with a nozzle cleaning kit.
Use the correct nozzle for your application.
Check the unloader valve:
This valve regulates pressure. If faulty, it may need adjustment or replacement.
3. Problem: Pressure Washer Stops Running
Overheating:
If the unit has thermal protection, let it cool before restarting.
Inspect the pump:
Check for oil levels (if applicable) and ensure the pump is not overheating.
Check for air locks:
Purge air from the system by running water through the unit without the nozzle.
4. Problem: Water Leaks from Pump
Replace seals or gaskets:
Worn seals or gaskets inside the pump may need replacement.
Inspect the pump housing:
Look for cracks or damage and replace the pump if necessary.
5. Problem: Soap Injector Isn’t Working
Check the injector system:
Clean the soap nozzle and tubing.
Ensure the soap solution is adequately mixed.
Verify that the injector is working only in low-pressure mode.
