When you get used to using your pressure washers, you'll expect them never to develop any fault. The pressure washer brings about convenience and less stress when cleaning any surface. But the pressure washer is also a machine that can develop a fault at any point in time. When this fault comes, you may need to call on an expert to help you troubleshoot and fix the problem with your pressure washer.

When pressure washers decide not to work, it's always a heartbreaking moment because you have probably depended on the pressure washer to help with some swift cleaning. It is advisable to call on an expert to help you check your pressure washer professionally when there are any issues with the device. But sometimes, you may be lucky enough to realize the problems, and with the right tools and knowledge, fixing the pressure washer on your own may not be an impossibility. This guide will give you some of the probable culprits why your pressure washer is refusing to start, especially when it's a gas pressure washer. Some of the possible causes include;

The spark plug has gone bad

The spark plug is probably one of the most underrated parts of a gas pressure washer, but it remains one of the most vital. Without it, the engine wouldn't start. When your pressure washer refuses to start, take a look at the spark plug to check for any damage. While checking, keep an eye for the porcelain insulator to know if there's a crack. Also, you may have a burnt electrode around the spark plug. To know if the spark plug is suitable, an instrument known as a spark plug tester is vital. The tester will deliver a spark when the spark plug is suitable, and it won't spark when it's bad.

The ignition coil develops a fault

When you turn on the engine of your gas pressure washer, the ignition coil transfers some voltage to the spark plug to keep it running. Once there's an issue with the ignition coil, the engine will not start. If it goes wrong while the pressure washer is on, it may not stop working immediately. While you're trying to change the ignition coil, ensure you take a look at the spark plug to ensure it's working optimally.

The carburetor is faulty

The carburetor is the pathway between air and gas used to run the engine. Because of the fuel and air mix, a common issue with the carburetor is clogging. When you have a clogged carburetor, your engine may refuse to start. What you can do to solve this is to take out the carburetor and wash it. In some cases, the carburetor may need a total replacement.


Apart from the general issue of no gas to run your pressure washer, there are other reasons why your engine may not start, as discussed above.
