#3. Fuel pump issue so check the pump connection

Examine further the fuel pump that should connect well to a fuel pump. The fuel pump begins from the fuel tank and down to the pressure washer motor for the engine to work. Your pressure washer will resist starting if a problem occurs with the fuel tank and the fuel pump. Leakage also occurs in the fuel pump. Thus, replace the fuel pump with another one. Seal the leakage to avoid leaking.


#4. Power cable leaked or damaged, so check it

The wired cable connects the electric pressure washer with the power source to gain energy and run. The pressure washer may fail to start if the power cable is leaked or damaged somewhere. A defective, leaked, or damaged cable fails to draw energy from the source of power. Thus, it remains the reason for a short circuit. In using the electric pressure washer, check first the cable properly before beginning it.


#5. Problem with water pump air and hose so check the air

The pressure washer does not start with the problem of water pump air and hose. You can fix it quickly. You only have to pump the water with a pressure washer. Wait until the air is evacuated from the hose.  Follow this to start your pressure washer and after that, go to a professional.


#6. Dirty air filter so clean it

One more reason why a pressure washer stops from starting is because of a dirty air filter. The air filter plays a role in operating the machine smoothly as it filtrates the air and goes through the pumps for the engine and pumps to work smoother. An air filter clogged up with debris and junk is not able to do its duty. As a result, the engine loses the ability to suck air to operate the washer pressure. Solve this problem and deal with the situation by cleaning the air filter. Do this quickly as you move it under warm water. Change the air filter too if it is too damaged or too dirty to operate.

#7. Faulty spark plug, so clean it first

A faulty spark plug is one reason why the pressure is not starting. The spark plug loses its ability to operate further. Its engine will stop from starting if it has a torn or worn-out spark plug. Clean the spark plug first. Clogs may fixate on the spark plug and prevent it from doing its activities. Look at the spark plug closely if something negative comes out from it. Check it with a spark plug tester to see if it is working or not anymore.


#8. Clogged carburetor so make sure of the correct ratio of air to fuel

The carburetor is essential equipment in the pressure washer. It also makes sure that the fuel and air mix proportionately. The ratio of air to fuel in the pressure washer is 12:1 & 15:1. The carburetor processes this ratio by itself. The carburetor that is junked up or clogged up thoroughly loses more of its capabilities. That’s when you get in trouble for burning the fuel. The effect is the failure in starting the pressure washer.


#9. Excessive air so pump the water until it is removed

The pressure washer engine may not start well if there’s too much air in the hose and the water pump. The thing is that you can fix it quickly. Pump the water until you remove the air from the hose. Thus, the pump starts and gets the water pressure to flow. It works to clear the air from the house.
