Campbell Hausfeld’s gasoline-powered pressure washers troubleshooting problems and their solutions

1)  Symptom: The engine won’t turn on or it becomes really hard to turn the engine on.

Possible cause of this problem: 

  • The fuel tank or carburetor is empty and doesn’t contain any gasoline.
  • The machine is running low on oil.
  • The start/stop button is positioned in stop mode.
  • There is water in the gasoline or the fuel is old. This can also be a reason.
  • The air-cleaning filter is dirty.
  • A spark plug is dirty or if it’s put into the wrong gap or if its shape isn’t the right one.
  • Spray gun remained closed and multiple other issues could raise this problem.


  • The fuel tank needs to be filled with gasoline so that the machine runs smoothly. The fuel tank and the carburetors also need to be inspected regularly.
  • Monitor oil level. Fill the tank with oil if it’s running short. 
  • If the switch is in an off position, move it to start.
  • Using a new fuel tank and dry plugs is always a good idea.
  • Clean all the necessary parts regularly. Remove them if it’s not working properly.
  • Also, clean the gap. Adjust it to the necessary proportion. Even replace it completely, if it’s not functional anymore.
  • Triggering the spray gun could be a good solution. 
  • If you still face any trouble see the engine manual for more i
  • nformation.

2) Symptom: Engine’s performance downgrades. It lacks power.

A possible cause for this problem.

  • If the air cleaner filter is plugged in partially then it could cause this problem.
  • Regular cleaning is highly advised. If a spark plug is dirty or wrong shaped then it could also cause this problem.


  • Cleaning and keeping the pressure washer neat is the best solution to this problem. Remove parts that are not working anymore.
  • Cleaning, adjusting, or replacing the gap also works.

3) Symptom: If the pump runs rough or shows low pressure. 

A possible cause for this problem.

  • If the tip is wrong sized then there’s a high chance that this problem may arise. 
  • Do look if the inlet filter is blocked or not.
  • Abrasives in water are also a reason behind this problem.
  • If the inlet is dirty and restricted it can’t perform its task properly and create low pressure.
  • Also, if the inlet gets worn up or the valves get discharged then it’ll also create low pressure.
  • High-pressure hose getting leaked can also be an issue.
  • if the pump gets drawn in air or the unloader’s seat is not working properly then you’ll also face problems like this.


  • The tips need to be replaced with a proper-sized tip so that the pressure washer can function accurately.
  • More regular inspection is advised. The more you’ll perform a maintenance check the fewer problems the machine will face.
  • Inspect the filters and also replace the packings if needed. 
  • The inlet must be cleaned regularly. And also check if the discharge valves are assembled in the correct order.
  • The garden hose also needs to be checked. There’s always a possibility that it may have collapsed. Inlets water flow may create some problems too. So that also needs proper inspection.
  • If damaged or not functioning properly replace the valves.
  • The same goes for a high-pressure hose, if it’s worn out then replace it immediately.
  • Make sure that all the hose and other fittings are placed properly and tight enough. Do regular inspection and replace them if necessary.

4) Symptom: Water leakage is seen from pumps under the manifold.

A possible cause for this problem. 

  • The main reason for this problem is the packings being worn out over time.


  • New packings need to be installed to get rid of this issue.

A possible cause for this problem.

  • If the humidity inside of the crankcase gets increased.
