Pressure Washer Troubleshooting For Off-Season Storage. If you’re planning to store your pressure washer for two months, then run RV antifreeze (standard automobile antifreeze is not recommended) through the pump as follows:

Gas Powered Pressure Washer Off-Season Preparation:

  • Disconnect the high-pressure hose and garden hose from the pump.
  • Tilt the unit on its side, placing a funnel in the inlet side of the pump.
  • Pour 6 oz of RV antifreeze into the pump while slowly pulling the start cord. This will pull the fluid into the pump. Your pressure washer is now ready for storage.
  • Like gas powered lawn mowers and edge trimmers, gas power washers need standard service every so often to replace sparkplugs, air filters and oil.
  • Check pressure washer pump seals for signs of leaks.
  • Remove gas from the tank and gas delivery system (hoses, etc.) or use a fuel stabilizer to prevent deposits from fouling the carburetor.
  • To prevent motor damage, run water through the system in the spring to purge any internal air pockets before restarting the motor.

Electric Pressure Washers:

  • Disconnect the high-pressure hose and garden hose from the pump.
  • Tilt the unit on its side and switch the ON/OFF switch into the ON position.
  • Using a funnel, pour 6 oz of RV antifreeze into the inlet side of the pump.
  • Universal electric motors need to have their brushes changed every 100 hours of operation. Induction motors don’t have brushes.
  • Turn the unit OFF. It is now ready for storage.
  • Check pressure washer pump seals for signs of leaks.
