Echo Pressure washer starts then stalls
When your Echo gas pressure washer starts then stalls, the carburetor is the most likely cause. Stale or ethanol-blended fuel left in the carburetor during storage can evaporate and leave a sticky residue that restricts the main jet, needle valve, or other passages. Clean the carburetor with carburetor cleaner, then rebuild or replace it if cleaning does not solve the problem. A clogged fuel filter is the next likely cause, especially if old fuel remains in the fuel tank, so drain the tank and replace the filter. A blocked fuel cap vent can also create a vacuum in the tank and cause the pressure washer to start and stop. Try loosening the cap slightly while the engine runs. If it stays running, replace the fuel cap. Next, inspect the air filter, which can restrict airflow and make the engine stall, and replace it if clogged. A clogged pre-cleaner is less common but can cause the same symptom. These checks can help when your pressure washer starts then dies, starts but won't stay running, or shuts off after a few seconds. Enter your model number to find the exact replacement carburetor, repair kit, fuel filter, fuel cap, air filter, or pre-cleaner for your Echo pressure washer.
01 - Echo 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 cause the engine to run stall. If the carburetor is clogged, try cleaning it with carburetor cleaner. If cleaning the carburetor isn’t effective, rebuild or replace the entire carburetor.

Highly Likely
04 - Echo Fuel Cap
As fuel is consumed by the engine, the level in the fuel tank lowers. To make up for this, the fuel cap uses a small vent to allow air to enter the tank. If the fuel cap vent is clogged, air won’t be able to enter the tank and a vacuum or “vapor lock” will occur. This stops the flow of fuel to the carburetor causing the engine to stall. To determine if the fuel cap vent is clogged, try slightly loosening the cap and then starting the engine. If loosening the fuel cap allows the engine to stay running it is likely clogged and will need to be replaced.
Highly Likely
05 - Echo Air Filter
The air filter may be clogged. If the air filter is clogged, the engine will get too much fuel and not enough air. As a result, the engine may stall. If the air filter is clogged, replace it.
Highly Likely
06 - Echo Pre-Cleaner
The pre-cleaner might be clogged. However, this is rare.
