Can’t Start Your Ryobi Pressure Washer? Some Helpful Tips


An irritating problem for Ryobi Pressure washers is not starting when you want to use them. There are two types of Ryobi pressure washers; electric and gas. Electric pressure washers are usually small pressure washers used for regular household cleaning. Gas pressure washers have a higher PSI rating and are suitable for more tough conditions. Both types of pressure washers can face the starting problem, even do the cause is likely to be different.

Can’t Start Your Ryobi Pressure Washer:

In general, Ryobi electric pressure washers won’t start due to a blown fuse, a burned capacitor, a damaged cord, or a faulty outlet. The most common causes for a Ryobi gas pressure washer not to start are a clogged carburetor, a faulty spark plug, a faulty ignition coil, a dirty air filter, or a cracked flywheel key.

Can’t Start Your Ryobi Pressure Washer? Some Helpful Tips 1

This article will provide you with in-depth information about the most common causes that prevent both Ryobi electric and gas pressure washers from starting. I will help you fix those issues without the need for a professional.

Reasons for an Electric Ryobi Pressure Washer Not Starting

The most common causes for a Ryobi electric pressure washer not to start are a broken cord, a damaged AC outlet, a blown fuse, or a burned capacitor.

We will look at each of those reasons in more detail:

● Electric Ryobi Pressure Washer Not Starting: Broken Cord or Damaged Plug

While troubleshooting a Ryobi electric pressure washer, the first and foremost thing to check is whether the AC outlet is working properly. Most of the time, the problem lies in the outlet or the cord.

Connect another appliance, like a lamp, to the outlet. This way, you know that it is working fine. If not, check the circuit breaker in the hose. If your plug isn’t working properly, use another outlet to plug in the washer.

It would be best if you also inspected the cord. If there are rips and breaks in the cord, you must either repair it or replace it with a new one.

● Electric Ryobi Pressure Washer Not Starting: Blown Fuse:

A blown fuse in an electric pressure washer won’t allow the washer to start. There are many reasons which can cause a fuse to blow. If you use a long extension cord with a small gauge, your fuse might blow because of the lower voltage. It’s recommended to use a 12-gauge wire cord if the cord is longer than 25 feet. Extension cords with small gauges don’t provide adequate power to the pressure washer. This can lead to the fuse blowing, preventing the pressure washer from starting.

If your main supply voltage is low, the motor of the pressure washer will pull more current and blow the fuse. You can easily check the fuse of your pressure washer at home with a multimeter. Simply take the fuse out and place the probes of the multimeter at the ends of the fuse. A perfect fuse has a resistance reading of almost zero. If the multimeter shows high resistance, this means that your fuse is damaged and needs to be replaced.

● Electric Ryobi Pressure Washer Not Starting: Burned Capacitor

If the fuse is fine, check the capacitor from the motor. Ryobi electric pressure washers may not start if the capacitor inside the motor is burned. To inspect the capacitor, remove the outer case covering the motor with a screwdriver. A bulging or blackening capacitor indicates damage. You must remove the burned capacitor and replace it with a new one.

Reasons for a Ryobi Gas Pressure Washer Not Starting

In general, a Ryobi Gas pressure washer won’t start due to an improper fuel mix in the tank, a clogged carburetor, a dirty air filter, a faulty spark plug or ignition coil, and a cracked flywheel key.

The most common reasons behind the Ryobi gas pressure washer not starting are the following:

● Ryobi Gas Pressure Washer Not Starting: No Fuel or Improper Fuel Mix in the Tank

Before troubleshooting your gas pressure washer, you must make sure that there is enough fuel in the tank. The pressure washer also won’t start if you don’t use the proper fuel mix.

Also, check that the hole in the tank cap is open. If not, the gas will not get to the carburetor. The last problem with the gas in your tank can be bad gas. If you leave gas in your tank for an extended period, more than a few months, gas can go bad. Bad gas can leave a sticky residue in various places. If you plan to store your pressure washer for some time, drain the gas from the tank. Another solution is to add some fuel stabilizers. Do not forget to do this also for your stored gas.

● Ryobi Gas Pressure Washer Not Starting: Faulty Spark Plug

Pressure washers won’t start when the spark plug is defective. Spark plugs become defective when carbon builds upon the electrode. The carbon build-up prevents a strong spark, meaning the pressure washer won’t start. Sometimes, the porcelain insulator in the spark plug gets cracked, resulting in the pressure washer not starting. The problem may also occur due to damaged or burned electrodes.

You can inspect the defective spark plug by simply removing it and checking it for corrosion and deposits. A spark plug tester can be used to check the spark plug. You can clean the spark plug with a metal brush and reinstall it. I recommend replacing it when it is in bad condition.

● Ryobi Gas Pressure Washer Not Starting: Fault in the Ignition Coil

If you have checked the spark plug and it’s working correctly, the starting problem can occur due to a faulty ignition coil. You can test the ignition coil with an ignition coil tester. If the tester fails you have to replace it.

● Ryobi Gas Pressure Washer Not Starting: Clogged Carburetor

The carburetor of the gas-powered pressure washer can get clogged due to bad gas. This often happens when the pressure washer is not used for an extended time. The old fuel in the tank breaks down and leaves thicker and sticky matter. This substance clogs the carburetor and prevents the machine from starting.

The carburetor supplies the air-fuel mixture to the engine. Low-quality gas, dust build-up, and inadequate maintenance can restrict the carburetor’s jet. The quantity of the air-fuel mixture in the engine is affected by these blockages. This causes the engine to produce noises and shut down completely in some cases.

The residue from bad fuel being left in the tank can create a restriction in the fuel line and the carburetor. If you notice bad gas, drain the gas tank. And replace it with fresh gas. Fuel in the tank must be replaced from time to time, or you have to add some fuel stabilizer.

To fix the problem, remove the carburetor and clean it with some carburetor cleaner. If cleaning the carburetor isn’t effective, you can purchase a carburetor repair kit to replace some of the components or install a new carburetor altogether. The pressure washer engine can idle up and down due to loose screws in the carburetor. Ensure that the screws of the carburetor are correctly tightened.

● Ryobi Gas Pressure Washer Not Starting: Dirty Air Filter

The air filter in the pressure washer filters the air to protect the engine from dust and debris. The engine isn’t able to suck enough air when the air filter becomes too dirty or clogged. In extreme cases, this stops the pressure washer from starting. If your pressure washer has a paper air filter, you need to replace it when it is dirty. A foam air filter can be cleaned with some warm water in the sink. Let it fully dry before putting it back. If the air filter is damaged, I recommend replacing it.

● Ryobi Gas Pressure Washer Not Starting: Cracked Flywheel Key

The flywheel key in the pressure washer protects the engine from stopping due to a sudden opposing force. It’s designed to prevent complete engine failure.

The flywheel key is a small metal part that ensures the correct flywheel position. A magnet mounted on the flywheel moves past the ignition module that delivers a signal to the spark plug. When the timing is not correct, the engine will not run.

Check the flywheel key. To do this, you have to remove the flywheel. If you find the key to be damaged, replace it.

How Do You Fix a Ryobi Electric Pressure Washer That Won’t Start?

To fix a Ryobi electric pressure washer that won’t start, you need to make sure that the outlet is working properly. Use an extension cord with the appropriate power rating. Check the fuse and capacitor in the pressure washer for any damage and replace them if needed.

Here are steps to follow to fix your Ryobi electric pressure washer that won’t start:

● Step 1: Check the Ryobi Cord and AC Outlet:

Check the cord for any wear and tear. Make sure that the outlet is working properly. Use another appliance, like a lamp, to test it. If it doesn’t work, check the circuit breaker and the earth leakage circuit breaker. The last one can trigger because of some moisture.

Use a multimeter to ensure that the AC outlet is providing enough voltage to operate the machine. If you are using an extension cord with a lower power rating, replace it with a better one. I recommend using a 12-gauge cord if its length is longer than 25 feet.

● Step 2: Check the Ryobi Fuse and Replace It:

Remove the fuse from the pressure washer and check if it’s blown. You can use a multimeter to check it. Place the probes of the multimeter at each end of the fuse and read the resistance reading. A perfect fuse has an approximately zero resistance reading. If you get a high rating, it means the fuse is broken. In that case, replace it.

● Step 3: Replace the Ryobi Capacitor:

Remove the case that covers the motor and check the capacitor. A blackened capacitor indicates that it’s burned. Disconnect the burned capacitor’s legs from the wires of the motor and install a new capacitor. Make sure to establish all the connections properly after reinstalling the new capacitor.

How Do You Fix a Ryobi Gas Pressure Washer That Won’t Start?

To fix a Ryobi gas pressure washer that won’t start, you need to clean the carburetor, spark plug, and air filter. You must also ensure that the tank of your pressure washer is filled with fresh fuel.

● Clean the Ryobi Carburetor

If the carburetor is dirty, the engine will not start. Or it will start but die immediately. Or it will die when you aks some more power from the engine.

Use the following steps to clean the carburetor from your Ryobi Gas Pressure Washer:

  • Step 1. Unscrew the front casing
  • Step 2. Detach the fuel lines: Detach the fuel lines leading to the carburetor. Remove any screws that connect the carburetor to the linkage. Remove the clamps carefully to avoid any fuel leakage.
  • Step 3. Remove the carburetor
  • Step 4. Examine the jets and screws: Check the jets and screws that may be causing the restrictions due to clogged dust. For unclogging and cleaning the holes, use a carburetor cleaner liquid.
  • Step 5. Reassemble the parts

● Clean the Ryobi Spark Plug

If you check the Ryobi sparkplug and you find it to be dirty. Use the following steps to clean it:

  • Step 1. Clean the area around the spark plug: This ensures that no dirt can fall into the cylinder.
  • Step 2. Remove the spark plug: I recommend using a proper spark plug socket. This is longer than a regular socket and protects the head of the spark plug.
  • Step 3. Clean the plug and inspect it for any damage: Use a metal brush to clean.
  • Step 4. Check the electrode and porcelain: If the electrodes are burned or if the porcelain is cracked, replace the spark plug.
  • Step 5. Reinstall the spark plug: Reinstall the old plug or new spark plug and tighten it. Do not overtighten do, that can damage the cylinder.

● Add Fresh Fuel to the Tank:

Carburetor’s jets can get clogged due to bad gas. The gas should not be left in the Ryobi tank for more than a month or two for gas-powered pressure washers. Older gas can get bad and leaves a sticky residue in the fuel lines and carburetor. Drain the old fuel and clean the tank and carburetor. Add fresh gas when you plan to use your machine.

● Clean the Air Filter:

The air filter in your Ryobi pressure washer filters the dust particles in the air. In extreme cases, pressure washers won’t start due to an inadequate supply of clean air. You can use the following steps to clean the Ryobi the air filter:

– Step 1: Open the air filter lid

Open the air filter casing located next to the fuel tank. Remove the air filter and clean the dust and debris inside the casing.

– Step 2: Clean the filter

If you have a foam air filter, use a mixture of soap and water to clean the dirt and debris. If you have a paper air filter, you have to replace it. If you find the air filter to be damaged, replace it.

– Step 3: Check for soap residue

After cleaning the filter, ensure that there is no soap residue left over on the filter. Let it fully dry.

– Step 4: Apply engine oil

To avoid the dust particles from reaching the engine, apply a little bit of engine oil on the filter. Oil attracts dust particles and prevents them from reaching the engine.
