6 common Reasons why Craftsman 2800 PSI pressure washer won’t start

You might be intrigued after finding out that your brand-new Craftsman pressure washer won’t start, but wait. You are not alone, and this is not the end of the world for you. Luckily, you can easily inspect your Craftsman pressure washer, rule out the underlying cause, and resolve it in no time. Below are a few common reasons discussed in detail, along with their possible solutions.

1.      Power Switch

Now that you are going to start your Craftsman pressure washer, make sure that you have dealt with the basic settings first. Ensure that the power switch is turned on and the power cord is plugged into the right socket. Secondly, check whether the fuel tank has enough gasoline to kick-start the pressure washer. Thirdly, check that the water supply is smooth to the pressure washer pump inlet and that the garden hose is kink-free.


Check all the power cords and sockets. Check the fuel tank for enough gasoline and the quality of the fuel as well. Also, ensure the hose has no obstructions and the water supply is perfect.

2. A damaged spark plug

A Craftsman pressure washer’s spark plug is essential to the engine’s igniting mechanism. Spark plug wear and damage over time can cause serious problems when attempting to start the pressure washer. The engine’s combustion chamber may not be able to ignite the fuel-air mixture if the spark plug is worn out or damaged. This may make it difficult for the engine to start or, in rare situations, prevent it from starting at all.


Use a spark plug tester to find out if the spark plug is broken. When the engine starts cranking, a bright spark should be visible between the tester’s terminals. If there isn’t any spark, the spark plug needs to be changed because it is broken.

3.      Clogged Carburetor

A typical cause of a Craftsman pressure washer not starting is a blocked carburetor. It can become clogged, usually by old fuel, dirt, or debris, which can limit or completely stop the fuel flow. This may lead to inadequate fuel getting to the engine, which could make it difficult or impossible to start.

One of the symptoms of a clogged carburetor is a sputtering, rough, or non-starting engine. You might try taking the air filter out and looking for any obvious blockages in the carburetor to help diagnose this problem.


Cleaning the carburetor completely is the first step in clearing a clogged one. First, cut off the gasoline supply, remove the carburetor, carefully disassemble it, and use carburetor cleaner or a special carburetor cleaning solution to clean all of the parts, including the jets and tubes. If the issue continues, it might be necessary to replace the carburetor.

4.      The ignition coil is damaged

It is possible that a malfunctioning ignition coil is the cause of a Craftsman 2800 psi pressure washer not starting. The electrical spark that ignites the fuel-air combination in the engine’s combustion chamber is produced by the ignition coil. The engine cannot start if the ignition coil is malfunctioning or broken because it may not generate a spark that is powerful enough or any spark at all.

When trying to start the engine, there should be no spark, intermittent spark, or the engine starting but stalling soon after as indicators of a malfunctioning ignition coil. Using a spark tester or a spark plug tester tool, you can determine whether the ignition coil is the problem.


Usually, the fix is to swap out the malfunctioning ignition coil with a new one.

5.      Broken Flywheel key

Broken Flywheel

If the flywheel key on your Craftsman pressure washer breaks or shears, that could be the reason the machine won’t start. The compact, frequently rectangular flywheel key is what attaches the engine’s flywheel to the crankshaft. Its purpose is to keep these parts in the correct alignment. This alignment may be thrown off if the flywheel key breaks or sustains damage, throwing off the engine’s timing.

The engine might not start at all or run strangely as a result. By removing the flywheel cover, you may physically inspect the flywheel to determine whether the flywheel key is the problem. It’s probably the source of the issue if you see that the key is broken or sheared.


It is necessary to install a new flywheel key and make sure it is positioned correctly as part of the solution. By doing this, the pressure washer should be able to start and function properly with the proper timing restored.

6.      Stale Fuel

One of the very common reasons for your Craftsman 2800 psi pressure washer not starting is that the fuel is outdated and stale. Stale fuel, being less combustible, is a primary reason for performance issues in a pressure washer.


A fuel stabilizer helps maintain the quality of the fuel, keeps it combustible for a longer time, and maintains its longevity.

Maintenance tips for Craftsman 2800 PSI pressure washer

To guarantee that the Craftsman 2800 PSI pressure washer works effectively and lasts a long time, maintenance is necessary. The following three upkeep suggestions:

1. Regularly check and change engine oil

The engine in your pressure washer needs clean, appropriate oil to run smoothly, just like any other gas-powered device. Prior to each usage, check the oil level and replace it as advised by the owner’s handbook, which is usually done after the first five hours of use and then on a regular basis after that. If you want to prevent engine damage, make sure you use the oil quality that is recommended by the manual.

2. Clean the air filter

The engine’s air filter keeps dirt and debris out, and a clogged filter can limit airflow and impair engine performance. Check the air filter frequently, and replace or clean it as needed.

3. Winterize for Storage

It’s essential to winterize the pressure washer if you reside in a region with harsh winters and won’t be using it for a long time to protect it from freezing-related damage. To stop fuel from clogging the carburetor, either empty the fuel tank or add a fuel stabilizer. Until the fuel lines are empty, keep running the pressure washer. In order to prevent corrosion during storage, you should also store it in a dry, sheltered area. You could also want to remove the spark plug and fill the cylinder with a small amount of oil.
