However, as with any power tool, gas-powered pressure washers experience wear and tear over time and will most likely need some form of repair down the road. Below are some do-it-yourself tips for fixing common gas-powered pressure washer repair problems.
No Water Flow
Remove the nozzle to check for blockage. Proceed to clean the nozzle if any obstruction is found before putting it back in place. Check the hose for blockage as well.
It’s possible the trigger gun might be defective. This problem can be resolved by purchasing a new one.
Check for blockages in the inlet and other parts. Clean the part to remove the obstruction before securing it back into its proper place.
Other possible reasons for low pressure could be air leakage, a worn nozzle or water leakage in the discharge valve. For these problems, contact the manufacturer or a tool repair store for a replacement part.
Pump Making Loud Noise or Abnormal Vibrations
Release the trigger gun to discharge any air in the pump. Proceed to look for water in the pump. If water is found, this might indicate the pump head seals are torn, which would then require purchasing a new pump.
Look for bearings and connecting rods that are worn or broken. Talk to a professional at your local power tool repair shop about whether buying replacement parts will solve the problem, or if the situation requires a new pressure washer pump instead.
Oil leakage due to a worn crankshaft seal or o-ring can be resolved by buying replacements. When adding oil, make sure to use the type recommended by the manufacturer.
Water leaks are usually caused by hoses that are damaged or improperly attached. Buying a replacement hose will resolve this problem.
Proper care and routine check-ups of the operating system of your pressure washer should minimize any potential problems that might arise. Before trying to repair your gas-powered pressure washer, make sure to read the manufacturer guidelines in order to gain a better understanding of the problem. And don’t hesitate to call an authorized repair maintenance professional when uncertain of the problem or uneasy about performing the repair yourself.
