​Generac Pressure Washer Troubleshooting Manual

​Now we know that you’re all probably excited to get to the pressure washer reviews so you can pick the best one. However, we feel that it’s better to start with something more informative to help you properly use your Generac pressure washer before you buy it. That’s why we’ll begin with a troubleshooting guide. This will help you be able to fix it should anything happen to it.

​Here are a few of the most common problems that even the Best Generac washer may experience and the respective solutions:

  • ​Pressure Too Low

​The first possible problem is pressure that’s way too low as compared to what was advertised. First of all, the problem could be the nozzle. You may want to check if you are using a high-pressure nozzle. If not, switch to one.

​Another thing you may want to see is if the nozzle is clogged with debris. Clean it out if it is. Also, don’t forget to check the water inlet for clogs. Clean the inside if there is debris.

  • ​Engine Does Not Start

​First off, you may want to check the gas to see if there is enough. If there isn’t, just fill up the tank to a significant amount. If gas isn’t the problem, then it’s probably a dirty filter. You can clean it up or replace it. Another thing you need to check is the spark plug. It can either be dirty or cracked. If it is damaged, replace it but if it’s dirty, just clean it.

​Other than that, you may also want to check the engine to see if it’s over-choked. If it is, then fully open the choke and start the engine again. Lastly, take a look at the intake valve. If it is somehow stuck, then the engine won’t work properly. If it is, then you may need some professional assistance to help you solve the problem.

  • ​Water Is Leaking

​Leaks are pretty common in pressure washers, but they do need to be addressed. Usually, the problem is with the pump. If the pump is quite old already, you can expect there to be a few leaks from time to time. For this kind of problem, we suggest that you just replace the pump.

​But if the pump is rather new, you don’t need to replace the whole thing. You can just replace the pump seals or maybe rebuild it.

  • ​Injector Doesn’t Work

​Finally, let’s talk about the injector. There are times when the injector won’t work and that the detergent won’t mix with the water properly. First, you need to make sure that the siphon tube is submerged in detergent. This ensures that the detergent will mix properly with the siphon tube.

​Next, check if the chemical filter is clogged. Clean it if it is. While you’re at it, also check the filter and clean it if it’s clogged. If the injection kit is fairly damaged, then the best course of action is to simply replace the injection kit.

​Now that we’re done with the troubleshooting guide, we can now move on to the Generac pressure washer reviews.
