WorkForce Pressure washer won't start
When a Workforce gas-powered pressure washer won't start, begin with the spark plug, the most likely cause. Inspect it for a cracked insulator, burned electrode, heavy carbon buildup, or no spark while the engine is cranking. If the spark plug checks out, inspect the carburetor. Stale or ethanol-blended fuel left in the carburetor is one of the most common causes of seasonal equipment problems. Old fuel can leave a sticky residue that clogs the carburetor and prevents the engine from starting. Clean it with carburetor cleaner, then rebuild or replace the carburetor if needed. A defective ignition coil is another possible reason your pressure washer is not starting, so test the coil after confirming the spark plug works properly. Finally, inspect the flywheel key. A sheared key can interrupt ignition timing, especially if the engine stopped suddenly after hitting a hard object. These checks can help explain why your pressure washer won't turn on or why the power washer will not start. Enter your WorkForce pressure washer model number to find the exact replacement spark plug, carburetor, ignition coil, or flywheel key for your machine.
01 - WorkForce Spark Plug
Inspect the spark plug for signs of wear or damage. If the porcelain insulator is cracked, an electrode is burned away or damaged, or there is heavy carbon buildup at the electrode, replace the spark plug. To determine if the spark plug is defective, use a spark plug tester. You should see a strong spark between the tester’s terminals when the engine is cranking. If there is no spark, this indicates that the spark plug is defective and should be replaced.

02 - WorkForce Carburetor
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

03 - WorkForce Ignition Coil
The ignition coil sends voltage to the spark plug while the engine is running. If the ignition coil is defective, the engine may not start. Before replacing the ignition coil, ensure that the spark plug is working properly. If you have confirmed that the spark plug is working properly, test the ignition coil with an ignition coil tester. If the ignition coil is defective, replace it.
Common
04 - WorkForce Flywheel Key
the flywheel key might have sheared in half. The flywheel key is a small metal piece which fits into the crankshaft and engages with the flywheel. If the engine stops suddenly due to the pressure washer hitting a hard object, the flywheel key breaks in half to prevent damage to the engine. To determine if the flywheel key is broken, remove the flywheel from the engine and inspect the flywheel key. If the flywheel key is broken, replace it.
