Ryobi 3100 pressure washer won’t start
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 some error or a problem.
If your Ryobi 3100 pressure washer won’t start, there must be one of the following issues.

- Degraded or old fuel
- Clogged carburetor
- Faulty ignition coil
- Flywheel key
- Sputtering engine

The spark plug of Ryobi 3100 is not working properly:
A spark plug is the first thing to check if your Ryobi 3100 psi gas-powered 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 Ryobi’s 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.
Degraded or old fuel
If you have left Ryobi 3100 psi gas pressure washer for more than 6 months with the gasoline in it, the gasoline can 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.
- Now turn on the fuel valve on the Ryobi 3100 fuel tank.
Ryobi 3100 Pressure Washer Won’t Start Due To 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 pressure washer from starting. If your Ryobi 3100psi power 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.
- 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.
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 Ryobi 3100 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.
If everything we discussed above is in good condition the flywheel key may be the problem. But how can you check if the flywheel key is the cause of the Ryobi 3100 pressure washer problem? Moreover, how can you fix it if it is?
For your information, 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 Ryobi 3100’s 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.
If your Ryobi 3100 pressure washer won’t start, the engine may be sputtering and shut down. 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.
Excess pressure in the pump
If your Ryobi 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 of your Ryobi 3100psi power washer 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.

Remove the spark plug wire from the spark plug.
Now make sure the water supply is turned off. After shutting off the water, squirt a little bit of lubricant into the recoil starter housing. Now pull the recoil starter rope a few times to work the lubricant in.
Finally, replace the spark plug wire and try to start the machine.
