1. Locate the base on the frame

Place all the materials into position on the floor. Find the center part of the base and place the electric motor in position. Secure the electric motor by placing the frame you are using on top. Also, ensure you lock your electric motor firmly on the base by using utility bolts and fasteners to prevent the electric motor from moving or falling off when using.

2. Position tank

Tanks that are commonly used by electric pressure include air and water tanks. Position the water and air tank along the rear of the frame. Secure the tanks and fasten them to prevent them from falling off. Further, connect the tanks to the outside faucet to ensure that your water tank has a water supply from the water hose.

3. Connect the outside faucet to the water hose

After connecting your water tank to the faucet, connect the faucet to the water hose, and the preferred water hose is a simple garden water hose. Ensure you connect firmly to prevent the tank, faucet, and garden hose from disconnecting.

4. Mantle the water pump

Using a pressure hose, collect your water pump and attach it to the water and air tanks. Ensure you attach the tanks firmly.

5. Install the electric materials

Attach your electrical components to the electrical motor. Connect the electric pressure washer to the power source. Ensure you don’t turn on your electric pressure washer.

6. Examine your electric pressure washer

Once you are done attaching your electrical components to the electrical pressure washer, test the outlet to see if it is working correctly. If it fails to work, try repeating the processes above until your electrical pressure washer works perfectly.

7. Install the nozzles

Purchase a nozzle that suits your electric pressure washer. Turn your electric washer on and leave it to run for a couple of minutes, approximately two to three, to ensure it is functioning as required. Also, test water flowing from the hose nozzle. Adjust air pressure and release water from the water tank by using the trigger on the hose nozzle.

If the electric pressure washer fails to function correctly, check the device you created again and fix any problems identified. You can also repeat the process of building your electrical pressure heater again.

8. Using the electric pressure washer, start cleaning your place

Rearrange all equipment in the house while securing any breakable items. Start cleaning your area while removing stubborn stains from the wall, floor, or even the roofs. Ensure you maintain your electric pressure washer to avoid any breakages.

Frequently asked questions

How can I repair my broken electrical washer?

If your machine is broken, identify the broken parts before mending the whole system. Follow the following steps to fix your machine.

  1. Disconnect your electric pressure washer from the power supply by unplugging the power cable from the socket.
  2. Scrutinize your machine to see if it is broken before troubleshooting. Inspect all parts and identify the broken parts or blocked parts. Sometimes, parts such as the nozzle are blocked; therefore, unblock all blocked parts. Check your water tank if it is leaking and try fixing it.
  3. Inspect 0-rings of your machine. Each machine has o-rings found on the pressure hose coupler. If the o-rings are damaged, consider replacing them with new ones. Remove the old o-rings from the pressure hose.
  4. Place the new o-rings on the electric pressure washer hose. Put the new O-ring in the correct position and use a screwdriver to push the new o-rings carefully into the pressure hose. Check if the new o-rings are secured using your finger.
  5. Inspect the water pump carefully. Open the fill cap on the water pump by unscrewing and check the level of oil available. If there is not enough oil, refill the cap with oil until it reaches the required level, and try testing your electrical pressure pump.

If your pump fails to function, consider replacing the water pump with a new one. Replace any damaged parts such as seals and o-rings.

  1. Inspect your electrical pressure washer fuse to see if it is blown out or damaged. Consider replacing the damaged fuse with the new one and testing your machine again to see it functions. If your machine still fails to function, consider replacing the whole machine.
  1. Visit a professional electrician. If your machine fails to function after using all the above troubleshooting tips, consult an electrician to help you fix the machine. You can also consult an electrician when your machine releases a burning smell.

Why does my electrical pressure washer produce low pressure?

Your electrical pressure washer produces low pressure due to the low water level in the water tank. Therefore, check the device’s water tank and pump enough water into the tank. Also, ensure the water tap is fully opened and not blocked.


The guide above will help you build your electrical washer instead of purchasing one as long as you have all equipment required to build your machine. The steps are simple and easy to follow. Finally, ensure you follow the steps above carefully to build a working machine.
