Powerhorse Power Washer Won’t Start – Causes and Solutions
If your Powerhorse power washer won’t start after following our startup guide then there must be one of the following issues. Below is the guide to fixing any such issues which are causing your pressure washer to not start.
Spark Plug May Be The Reason Powerhorse Power Washer won’t Start
A spark plug is the first thing to check if your Powerhorse pressure washer won’t start. Any signs of wear and tear or damage to the spark plug can resist the starting of the engine.
Remove the spark plug from the engine and check the tip or end of the spark plug for any cracks, signs of burning, heavy carbon build-up, or corroded electrode.

How To Clean the Spark Plug
To clean it dip the tip of the spark plug in the rubbing alcohol for at least one minute and scrub it with a hard brush. Clean as deeply as possible.
Clean all the residue properly. Now check the gap and adjust according to the manual.
Now put the spark plug back into the engine and check the spark. If there is a strong spark it means the plug is working well but if there is no or a low spark then it should be replaced immediately.
Powerhorse Gas Powered Washer won’t Start Due To Degraded Fuel
When you leave a gas power washer for more than 6 months with the gasoline in it, the gasoline will have low volatility and low octane. This oxidized and highly contaminated fuel often causes a lack of combustion ultimately causing a low engine performance or a failure to start the engine.
To resolve this issue:
- Drain the dirty and oxidized fuel.
- Take a good carburetor cleanerand clean the fuel tank with it thoroughly.
- Now full the fuel tank with fresh and good quality fuel.

Powerhorse Power Washer Won’t Start due to Clogged Carburetor
Powerhorse power washers are a popular choice for homeowners looking for an easy and affordable way to clean their homes and property. However, they can be frustrating when they don’t start due to a clogged carburetor.
Carburetors are small, precision-machined parts that help mix fuel and air for an engine. When they get clogged with dirt, dust, and other debris, they can prevent a power washer from starting. If your pressure washer won’t start, the carburetor may be to blame.
Fortunately, there are a few things you can do to clean a carburetor and get your machine up and running again. The most important thing is to avoid using harsh chemicals or solvents, which can damage the delicate parts inside the carburetor.
- One is to remove the carburetor and clean it with a small brush or pipe cleaner.
- You can also try spraying a small amount of carburetor cleaner into the carburetor opening to dissolve the clog
- If spraying still can’t start the engine then remove the carburetor from the engine and submerge it in a container of carburetor cleaner. Be sure to follow the instructions on the cleaner carefully.
- If these methods don’t work, you have to replace the carburetor.
Powerhorse Pressure washer engine won’t start due to Faulty Ignition Coil
The ignition coil on a pressure washer is responsible for providing power to the spark plugs. When it fails, the engine will not start. The first step in diagnosing and repairing a pressure washer with a bad ignition coil is to determine whether the coil is getting power. To do this, use a multimeter to test for continuity between the coil’s positive (red) and negative (black) terminals. If there is no continuity, the coil is bad and must be replaced.
Powerhorse Pressure washer engine won’t start due to the Flywheel key
If everything we discussed above is in good condition the flywheel key may be the problem. But how can you check to see if the flywheel key is the problem and how can you fix it if it is?
The flywheel key is a small, rectangular piece of metal that fits into a keyhole on the flywheel. It helps to align the flywheel and the crankshaft when the engine is starting. You can check it by removing the flywheel from the engine. Examine the flywheel key for any damage. If the key is missing, damaged, or misplaced, the engine may not be able to start and you have to replace the flywheel key.
The power washer won’t start due to a sputtering engine
If your power washer won’t start, the engine may be sputtering. This is due to a number of problems, including a dirty air filter, low fuel levels, or a clogged fuel line. You can troubleshoot the problem by checking the air filter, filling the gas tank, and cleaning the fuel line.
Powerhorse Pressure Washer won’t start due to excess pressure in the pump
If your power washer is not starting, it may be due to excess pressure in the pump. This can be caused by several factors, such as a clogged nozzle, a kinked hose or water that’s too hot. If the pump is not able to expel the water fast enough, it will create excess pressure and eventually cause the washer to stop working.
The best way to prevent this from happening is to keep the nozzle clear of debris and make sure the hose is not kinked. However, You can also release some of the pressure by pressing the trigger of the spray wand. Just after releasing the pressure, you can pull the cord to start your power washer.
What to Do if You Can’t Pull the Recoil Cord Of pressure washer

Troubleshooting Powerhorse Gas Powered Pressure Washer
How to Keep Your Powerhorse Pressure Washer Running Smoothly
Pressure washers are a valuable asset for keeping your home and property clean. However, they can be expensive to replace if they break down. Here are some tips on how to keep your Powerhorse gas-powered pressure washer running smoothly in order to avoid damaging the equipment or causing injuries:
Inspect For Any Potential Leaks
To keep your pressure washer running smoothly it is recommended to inspect it for any leaks. Leaks can cause the pressure washer to run inefficiently and can also reduce the lifespan of the unit. If you spot any, make sure to fix them as soon as possible.
Check For Fuel and oil leaks
These are the most common type of leaks, so make sure to keep a close eye on these components.
Fuel and oil leaks are the number one cause of gas pressure washer fires. Before starting your Powerhorse pressure washer, check for fuel and oil leaks. Look for fuel or oil on the engine, pump, hose, or any other part of the pressure washer. If you see a fuel or oil leak, do not start the pressure washer. Repair the leak before using the pressure washer.
Check For Water leaks Before Starting The Powerhorse Pressure Washer
Water leaks can add up to gallons of wasted water each day that’s why it’s important to check for water leaks before starting your pressure washer.
Look for water leaks around your pressure washer, garden hose, and high-pressure hose. If you find a leak, turn off the water supply to the fixture and fix the leak.
Check the Spray Gun and Trigger
When you are using a pressure washer, it is important to make sure that the spray gun and trigger are in good condition. If they are not, you could end up with a lot of problems like low pressure or no pressure at all.
Always check the spray gun and trigger before starting the pressure washer. Make sure the trigger is in the off position and that the spray gun is tightly attached to the wand.
The trigger is the part of the spray gun that you use to control the flow of water. If the trigger is not working properly, you could not use the machine for power washing.
Check Hose and Nozzle
The next step is to check the hose and nozzle for any damage. If the hose is torn or kinked, it will restrict the flow of water and reduce the pressure of the washer. The nozzle can also become clogged over time, which will limit the amount of water that is released.
Clean Machine Regularly
It is also important to clean your machine regularly. This will help keep it running smoothly and prevent any build-up from occurring. Use a mild detergent and a brush to clean all of the surfaces of the pressure washer.
Be sure to rinse off all of the suds before using the machine again. To clean the hose, just remove it from the unit and spray it with a garden hose. You should also check for any kinks in the hose, which can reduce water flow.
Clean the Pump
The pump is one of the most important parts of the pressure washer, so it’s important to clean it regularly. To clean the pump, simply remove the filter and spray it with a garden hose. You should also check the pump for any debris or grass that may have gotten caught in it.
Check Oil and Fuel Level before starting the pressure washer to run it smoothly
If you are going to be using a pressure washer this summer, it is important to check the fuel and oil levels before starting it. This will help to ensure that the pressure washer runs smoothly and does not overheat.
Check Fuel Level
In order to check the fuel level, locate the fuel cap on the pressure washer. It is usually located on the upper part of the machine. Once you have found the fuel cap, remove it and look inside. There will be a fuel gauge or indicator on the pressure washer that will tell you how much fuel is left in the tank.
If the fuel level is low, fill the tank with fresh gasoline.
Check Oil Level
When you are finished using your pressure washer, you should always check the oil level before you start it up again. This is to ensure that the pressure washer will run smoothly and that you won’t damage the engine.
The oil level should be checked every time you use the pressure washer. You can find the oil level dipstick on the side of the engine. The oil level should be between the two marks on the dipstick. If it is not, you will need to add more oil. Be sure to use the type of oil specified in the owner’s manual.
Check and Clean Air Filter To Run Pressure Washer Smoothly
Air filters should be checked and cleaned often to keep the Powerhorse pressure washer running smoothly. If they are not kept clean, the air filter will become clogged and the pressure washer will not work as well.
A dirty air filter reduces the amount of air that reaches the engine, which can cause the pressure washer to run poorly and could eventually damage the unit.
To clean the air filter, remove it from the pressure washer and gently tap it against a hard surface to remove any large debris. Then, use a vacuum cleaner to remove any smaller particles. Finally, spray the filter with a light coating of oil to keep it moist. It is important to note that the air filter should not be soaked in water, as this will damage it.
Moreover, an air filter is highly prone to dirt and debris and often requires a replacement. Just cleaning it won’t help sometimes so replace it with a new one whenever required.
Other Measures To Always Start Your Powerhorse Power Washer Smoothly
- Always use the correct nozzle for the job. Trying to use a high-pressure nozzle on a low-pressure job will damage the washer and could potentially void the warranty.
- Be sure to keep the pump oiled. This is a critical step that many people forget. If the pump isn’t oiled, it will overheat and eventually break down.
- Start the engine and allow it to run for a few minutes to warm up, especially in colder weather.
- Press the trigger gun and hold it down to release the pressure in the pump before starting.
A Powerhorse power washer is a solid machine but any negligence on your part can stop it from starting properly or maybe it won’t start when you want it to be.
Therefore, always remember these points:
Never start your Powerhorse Power washer without the inflow of water in the pump. Not only will this damage the pump, but you may also create a hazardous situation for your machine.
Always perform bi-annual preventive maintenance if you use your pressure washer regularly. Properly drain all the water out of the pump and flush it with pump anti-freeze/lubricant. Store your pressure washer properly to keep it functioning at its best.
