Why Does My Electric Pressure Washer Keep Cutting Out?

Do you have a problematic pressure washer that cuts out every few minutes while in use? Why does my electric pressure washer constantly cutting off, you might be wondering. You’re not on your own.

In today’s world, many households have pressure washers. They make cleaning easier by maintaining a greater degree of cleanliness. However, for them to do so, they must be in good operating order.

It’s frustrating to have a pressure washer that is constantly cutting off. That’s why we’ve outlined a few measures you’d do if you were in that situation. You’ll discover that it’s pretty simple and doesn’t necessitate hiring an expert.

Why Does My Electric Pressure Washer Keep Cutting Out?

  • Power Supply of Your Pressure Washer

A defective power connection is the first and most evident. First, check the plug; it’s easy to get carried away and over-extend the cord when using it. This can cut the electricity by slightly removing the plug from the power socket.

Another typical issue is the use of an extension cable. Most manufacturers recommend using an extension wire with a constant 13 amp rating and a length of no more than 10 meters (30 feet). Check the extension cable’s plug connectors and make sure it’s completely unwound.

  • Incorrect Start-Up Procedure

Pressure washers are constructed so that they can detect when water is running and then enhance the flow using the water pump when the trigger is pressed. The machine, however, will cut off if there is an air block in the system.

  • Leaking Hose

Check all garden hose connections since the engine may cycle if the pump does not receive enough water. When electric pressure washer motors detect too much pressure build-up in the water pump, they cycle. The motor resumes building pressure when you release the trigger, releasing the water pressure.

  • Insufficient Hose Diameter

Replace your garden hose with one that has a giant diameter pipe. This will allow for a greater water flow to this pressure washer.

  • Unloader Valve Fault

The unloader valve, also known as a pressure regulator, controls the pressure in the pressure washer. The unloader valve can either lose water pressure or allow too much water pressure to build up if it isn’t operating correctly. Ensure that there are no leaky washers or seals and that the spring is in good operating order.

  • Problems with Water Pumps

Check all seals and bolts for tightness if the water pump leaks any fluid, either oil or water. If the leaks persist after tightening the bolts, contact the manufacturer if the pressure washer is still under warranty. Contact a specialized pressure washer repairer if this isn’t the case.

While we’re on the subject of water pumps, electric pressure washers employ three different sorts of pumps. They all have various lifespans and costs. Therefore the price and lifetime of your pressure washer will be affected.

  • Clogged Filters

On some pressure washers, the water inlet filter is visible on a screen on the pump; check to see if it is blocked and clean as needed.

  • Overheating 

When you use your electric pressure washer on a hot, sunny day, the water in the garden hose heats up, forcing the water pump to work harder, which causes the engine to overheat. This will ultimately shut down your machine, but if you smell burning or see smoke while using your pressure washer, turn it off and unplug the power source right once.

Steps To Prevent Pressure Washer From Shutting Off After A Few Minutes (Important Tips)

  • Step 1: Ensure that your hands are parched. Also, make sure the connections are dry and not touching any damp ground. Now is the time to put on your rubber gloves.
  • Step 2: Turn off the electricity to the electric pressure washer. You don’t want any electrical mishaps while you’re working.
  • Step 3: Inspect the air filter for any blockage. Clogging might cause the washer to cut off due to a buildup of pressure. Proceed to the following step if it isn’t clogged.
  • Step 4: Make sure the unloader valve is in excellent working order. If your machine continues cutting off, it’s very certainly due to a faulty unloader valve, as we’ve already said.

If everything appears to be in order with your pressure washer, but the electric pressure washers keep shutting off, resetting the unit may be the solution.

Before turning on the machine, switch it off and squeeze the spray gun’s trigger to create a constant stream of water.

When you turn on the electric pressure washer and neglect to squeeze the release nozzle right away, the pressure might build up within. After a while, the appliance may switch off as a result of this circumstance.

You can remedy the problem by pressing the release nozzle. When you press it, the pressure switch disengages, allowing the pump to turn on.
