Ridgid Pressure washer starts then stalls
If your Ridgid gas pressure washer starts then stalls, the most likely cause is a clogged carburetor. Stale or ethanol-blended fuel left in the carburetor during seasonal storage can evaporate and leave a sticky residue that restricts fuel flow, causing the engine to start and stop or run for only a few seconds. Clean the carburetor with carburetor cleaner first; if that does not solve the problem, replace the carburetor or install a carburetor repair kit. Next, check the fuel filter, which can also become restricted by old fuel. Drain the fuel tank and replace the filter if needed. A clogged fuel cap vent can create a vacuum in the tank and cause the pressure washer to shut off after a few seconds. Loosen the cap slightly as a test, and replace it if the engine stays running. A dirty air filter can limit airflow and make the engine stall, so replace it when clogged. The pre-cleaner is another possible cause, although it is less common. Whether your pressure washer starts then dies, starts but will not stay running, or keeps stopping, enter your model number to find the exact replacement part for your Ridgid pressure washer.
01 - Ridgid 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 - Ridgid 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 - Ridgid 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 - Ridgid Pre-Cleaner
The pre-cleaner might be clogged. However, this is rare.
