Generac Pressure Washer Troubleshooting. Pressure washers are much easier and faster than garden hoses.
They can also be used as a kind of paint preparation tool. They can remove old or dirty paint and dirt.
Its use of water is about one-fifth that of a garden hose, saving water in the process. Sometimes your Generac pressure washer may not function fully, even if it normally does.
When using your Generac pressure washer, sometimes it may not behave as expected. If this happens, know what to do by following these simple troubleshooting steps:
Generac Pressure Washer Troubleshooting
By following these simple troubleshooting steps you can ensure that your pressure washer continues to work how it should and does not need repairing or fixing immediately:
Have trouble starting a Generac pressure washer
Inspect the spark plug for damage. You should replace the electrode if the porcelain is cracked, an electrode is burned away or damaged, or if there is heavy carbon buildup at the electrode.
Judging whether a spark plug is fit to use can be tricky so you will need a device to test the spark plug’s safety.
Use a handheld tool that shows if each spark plug has electricity coming through it when starting the engine.
If no electricity comes through it, then it needs to be replaced because it’s broken and you won’t get an engine start with that type of problem at all.
Badly clogged carburetors can also cause poor starts but this could be from fuel becoming stuck and blocking off key parts inside the carburetor itself.
Attempts to get rid of any bad fuel should first begin by using a carburetor cleaning tool but if this doesn’t help and the carburetors are still blocked, then emptying out all the gas and cleaning out all .
The pressure washer starts then stops
When fuel is pulled into the pump, which it will do as soon as the pressure washer starts up, the fuel level will lower in the tank and air will enter the tank to make up for that.
If there’s a bunch of dust or leaves and stuff in your pump really grind up into dust or can be clumped together then sometimes it can act like a little piece of paper or leaf stuck in a fuel line when you try to get gas.
It’ll cause enough back pressure to stall out the engine, so check if your spray wand won’t run at all for no reason.
So, if your spray gun does nothing on the first squeeze, pull out a 20 wt oil filter from K&N and replace your old one. That’ll take care of any problems right away.
Pressure washer running roughly
If a spark arrestor is blocked, the engine may breathe roughly. To unblock it, take off the spark arrestor and clean it with a wire brush. You might also replace the spark arrestor if this obstacle occurs often.
If the fuel is sticky, it can clog up the carburetor and lead to rough engine operation.
If the carburetor is clogged, clean it with carburetor cleaner. If cleaning it doesn’t work, you may need to rebuild or replace the carburetor.
Pressure washer leaks water
Pumps in pressure washers tend to wear out quickly. If you intend to use your pressure washer more than a few times, then you need to replace the pump and all of its related components.
If you don’t intend to use your pressure washer that often, then consider replacing just the pump itself or all of the seals (depending on how fast each individual seal wears out). It’s sometimes better to replace the entire thing.
There is no pressure on the Generac pressure washer
You may need to rebuild or replace the pump. If the pump is more than a few years old, and you use the pressure washer fairly often, replace the pump.
If the pump is relatively new, and you don’t use the pressure washer often, either rebuild the pump or replace its seals.
The pressure washer soap injector is not working
Replacing the chemical injection kit is necessary. A chemical injection kit contains all the parts needed to repair most problems with the injector system.
