Check the Fuel and Oil
One of the first components to check when your pressure washer won’t start is the fuel and oil levels. Make sure that the fuel tank is properly filled with clean and treated gasoline. Remember that untreated gasoline causes clogging and breakdown of the engine. Similarly, check the oil levels and ensure that the oil is fresh and clean. Low-level or dirty oil can quickly damage the engine and cause it to stall.
Inspect the Spark Plug
Spark plugs are a crucial component in the startup process of your pressure washer. A damaged or dirty spark plug can cause ignition failure and prevent your pressure washer from starting. Take your spark plug out and inspect it thoroughly for any dirt or damage. If it appears worn-out, you should replace it altogether. Additionally, ensure that your spark plug is tightly secured in the engine and is properly connected.
Clean the Carburetor
The carburetor is another part of the pressure washer that you should check when it won’t start. The carburetor plays a crucial role in mixing the fuel and air ratio required to power the engine and move the pump. If the carburetor is clogged or dirty, it could be restricting the flow of air and fuel into the engine. Disassemble the carburetor and clean it thoroughly, using an approved carburetor cleaner and the manufacturer’s cleaning instructions.
Check for Clogged Filters
Pressure washers have various filters (air, fuel, and oil filters) that work together to keep the engine clean. If any of the filters become clogged, it restricts the proper fuel flow and air intake, causing the engine to stall. Ensure that all the filters are cleaned and properly installed. Any dirt or debris that accumulates on the fuel filter can also be cleared by pouring gasoline into it and cleaning it thoroughly.
Consult a Technician if Necessary
If after following all the above steps, your pressure washer still refuses to start, it may be time to call a technician. In some cases, the actual problem may be an internal engine issue that requires professional intervention. Do not attempt to open the engine yourself, as it can be dangerous and cause further damage to the machine. It is always best to take your non-starting pressure washer to an experienced technician who can determine the actual problem and fix it.
