Ryobi Power Washer Won’t Start – Causes and Solutions – Easy Troubleshoot

If your Ryobi pressure washer won’t start after following our startup guide then there must be one of the following issues. Below is the guide to troubleshooting the Ryobi pressure washer and any such issues which are causing your machine to not start.

Ryobi Pressure Washer won’t Start – Spark Plug May Be The Reason

A spark plug is the first thing to check if your Ryobi 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.

If there is any damage, heavy black build-up on its tip or corrosion then it is best to change the spark plug. But if you don’t want to buy a new one in hurry you can just clean the plug and check if it works.

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.

Ryobi Gas Pressure Washer won’t Start Due To Degraded Fuel

When you leave a gas pressure 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 cleaner and clean the fuel tank with it thoroughly.
  • Now full the fuel tank with fresh and good quality fuel.
  • To keep your fuel fresh add a good fuel stabilizer.

Ryobi Pressure Washer Won’t Start – Clogged Carburetor

Ryobi pressure 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.

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.

Ryobi Pressure Washer Engine Won’t Start Due To Faulty Ignition Coil

The ignition coil on a pressure washer is responsible for providing pressure 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 pressure.

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.

Ryobi 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?

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 pressure washer won’t start due to a sputtering engine

If your pressure 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.

If your pressure 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 pressure washer.

What to Do if You Can’t Pull the Recoil Cord Of Ryobi Pressure Washer

If the recoil starter rope on your gas pressure washer won’t pull, don’t panic. You can usually fix the problem without having to take the machine to a repair shop. Here’s how:

  1. Remove the spark plug wire from the spark plug.
  2. Make sure the water supply is turned off.
  3. Squirt a little bit of lubricant into the recoil starter housing.
  4. Pull the recoil starter rope a few times to work the lubricant in.
  5. Replace the spark plug wire and try to start the machine.

  • 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.
