Gas Pressure Washer Engine Shutting DownUpdated 6 hours ago
Gas pressure washer engine shutting down can be due to a number of reasons. Please go through the following chart to troubleshoot your pressure washer.
Problem | Probable Cause | Solution |
Engine does not start | Stale fuel | Gas without stabilizer sitting in tank for more than 30 days degrades and does not ignite. Drain old fuel and replace it with fresh fuel. |
Low oil shutdown | Your engine has a low-oil sensor. Check the dipstick, and top-up engine oil as required. | |
Spark plug – excessive carbon buildup or incorrect gap | Check & replace if necessary. | |
Engine dies when you pull the trigger | Incorrect nozzle size | Incorrect nozzle size can cause the engine to bog down. Please ensure that you are using the correct sized nozzles. |
Clogged nozzles | Clean nozzles | |
Stuck unloader valve | Check & replace if necessary | |
Engine only runs with the choke on | Clogged carburetor | If the engine starts but dies when you turn off the choke, the "jets" inside are likely restricted. Clean and restart engine. |
Engine starts, but dies after a few seconds | Low oil shutdown | Your engine has a low-oil sensor. Check the dipstick, and top-up engine oil as required. |
Blocked fuel cap – engine starts, but dies after a few seconds | Most caps have a tiny vent to allow air in as fuel goes out. If it’s clogged, clean and restart the engine. | |
Dirty air filter – engine starts, but dies after some time | Check & replace if necessary | |
Dirty spark plug – carbon build up | Check and clean. Replace if necessary |
