We’ll also tell you how to drain your pressure washer for heated storage conditions, plus we’ll give you the answers to some commonly asked maintenance questions.

Steps for winterizing a Hotsy pressure washer

Winterizing your pressure washer is simple and involves the following:

  1. Disconnect the water supply from the pressure washer and connect the antifreeze solution container.
  2. Fill the solution container with antifreeze solution or wiper fluid.
  3. Turn on the pressure washer so that the solution starts flowing.
  4. When the solution starts coming out of the trigger gun, direct it back into the container.
  5. Let the solution cycle through the pumping system a few times by opening and closing trigger gun in order to reach all the nooks and crannies.
  6. Turn off the machine as well as the solution supply.
  7. For machines with a flow tank, simply fill the tank with the solution and follow the same process.

Steps for draining a Hotsy pressure washer

If you’re storing your pressure washer in a location that is above freezing (0° C), you don’t need to winterize the machine, but you do need to drain it to reduce the risk of damage.

  1. Turn off the pressure washer and detach the supply hose and high-pressure hose.
  2. Squeeze the trigger of the spray gun until all the water has been drained from the wand and hose.
  3. Restart the pressure washer and let it run very briefly (for about five seconds), until no water comes out of the high-pressure outlet.

Can a pressure washer freeze?

Yes. Any water that’s left in the pressure washer pump, coil, fittings, gun jet or hose can freeze. And since water expands when it freezes, it can damage these components.

Is it ok to run a pressure washer without water?

No. A pressure washer needs to have water circulating through it while running, or else the seals, gaskets or other components may get damaged.

How do I protect my pressure washer pump?

To make your pump last longer, flush it out after each use, or as often as possible, with a pump lubricant. This protects against mineral and rust buildup caused by moisture in the pump.
