5 Common Reasons Why Your Gas Pressure Washer Keeps Turning Off.

Don’t worry if your gas-powered pressure washer shuts off while you’re using it; in most circumstances, the problem is simple to resolve. Although it is undoubtedly quite aggravating, most problems can be fixed with common equipment that you most likely already have at home.

This issue is often brought on by a clogged fuel or air filter, which is simply and quickly fixed. All you need to do to fix the issue is clean or replace the filter, but let’s look at each possible issue and solution in more depth.

When your pressure washer cuts off, check these first.

Let’s go through a brief checklist of the obvious items to make sure you haven’t overlooked a really simple change before we move on to some more substantial remedies. Verify that:

  • You’ve got enough gas.
  • Every hose connection is secure.
  • You have enough oil.
  • Turn off everything, wait 10 minutes, then turn everything back on. Carburetor Issues (Gas Pressure Washers)

The carburetor should be checked first if your pressure washer often shuts off while you are using it.

A significant portion of gasoline that is left in the tank often evaporates. If you’re not cautious, this might lead to the formation of a thick, sticky material that can block the carburetor.

Consider where you typically keep the washer; you could find that it has been there for a long, which can lead to the accumulation of sticky residue in your carburetor.

What actions should you take to inspect the carburetor? First, snap a photo of the carburetor’s configuration. The picture will make it easier for you to figure out where everything goes after you’ve done taking apart the washer’s various parts. After that, shut off your fuel valve and unplug the gasoline line.

To access the carburetor, remove your spark plug cap, throttle lid, and intake. You may then disconnect the gas line, which is located between the fuel tank and the carburetor, after removing these.

The carburetor should then be removed after being completely emptied of its previous fuel. The bolts holding the carburetor to the engine may be taken out to do this. Gas within the carburetor should be thrown away after disconnecting the throttle cable.

Determine if the carburetor is rusty or not by giving it a close inspection. If it’s rusty, you probably need to replace it entirely. Usually, if it’s only filthy, you can clean it by disassembling it first.

tidy the carburetor

Find the pin connecting the float to the metal body of the carburetor and remove it to disassemble it. The needle valve may then be removed. The carburetor may then be cleaned at that time using products like Gumout Jet Spray or WD-40 Specialist, both of which are great.

For the greatest results, be sure to spray it on all of the metal components you can see within the carburetor. After that, give everything a good wash down to dry.

Checking for blockages in the idle and main jets is the next thing you should do. You may wipe them out with a little wire brush if there any.

Take your components that have been cleaned, rinse them with water, and then dry them with compressed air. The other parts may also be cleaned with soap and water, and you can look for any damaged gaskets to see if they need replacement as well.

Put the following things back after these procedures are finished:

Pin Gaskets, a needle valve, a carb bowl

Connect the carburetor to the engine after placing each of these pieces in their rightful spot and ensuring that everything is back where it belongs.

The majority of the time, this cleaning will be sufficient to stop your pressure washer from turning off, but if it isn’t, you may get a kit with carburetor components in it and replace just those parts that need to be changed.

The kits are inexpensive, and they can save you from having to replace the carburetor entirely.

The best approach to ensure that your carburetor isn’t experiencing issues is to prevent it from being clogged in the first place, of course. How? You may get assistance by following two simple guidelines.

Never use anything other than brand-new gasoline, and don’t allow it to become too old.
Employ a gasoline stabilizer.

First, never utilize gasoline that has been older than 24 hours. Second, apply a gasoline stabilizer regularly to help keep your fuel fresher for a lot longer. If you want to keep your carburetor clean of muck month after month, these two remedies are an excellent place to start.

The fuel filter and fuel cap clog

Your gasoline cap and fuel filter are also susceptible to clogging, much like your carburetor. When the fuel cap vent becomes blocked, no air can enter the tank, which causes a vapor lock and prevents the gasoline from flowing where it should.

Just remove the fuel cap, run your pressure washer, and see if it solves the issue. You don’t have to change the cap if it begins running smoothly.

If not, you may need to replace it as this often indicates that the fuel filter is blocked and unable to function correctly.

Gas cannot enter the carburetor for proper operation when a fuel filter is blocked. When gas is left in the tank for an extended period of time, it may also get sticky and clog the filter. Follow these easy steps if you’ve decided that your gasoline filter needs to be replaced:

Ensure that the fuel valve is closed at the fuel tank’s base; if you cannot see the fuel valve, you may simply clamp the fuel line.
Remove the metal clamps holding the filters in place if there is one in the gasoline line, then slide them out.

If the fuel cap or fuel filter is malfunctioning, you may need to repair one or both of them in order to get the pressure washer operating properly once again. With only a few simple items that you presumably already have at home, you can do both of these very easy activities.

The spark arc is a Gas pressure washer issue that is filthy

All pressure washers have spark arrestors, whose primary function is to prevent the washer’s engine from releasing harmful sparks (to say the least). The problem is that over time, soot in the washer might accumulate and block your spark arrestor.

The soot and grime may be cleaned off of it using a simple wire brush. Spark arrestors are tiny screen installations that operate continuously to put out sparks; as a result, soot may accumulate very fast.

You may clean the spark arrestor with your wire brush fairly easily after removing it, and you won’t need any soap or cleaning agent to accomplish so. Simply use the wire brush to dig into the nooks and crannies to scrape out as much soot as you can, which may be quite a bit.

The spark arrestor probably needs to be changed if this doesn’t work or if you discover that it is rusty or in poor condition.

Examine the air filter.

In order for the engine and carburetor to function properly, just like in your automobile, the air filter in your pressure washer must be clear of dirt, dust, and other obstructions.

The likelihood that dirt and debris may enter the carburetor and engine increases with the amount of dirt and debris present in the air filter.

This limits the airflow into the carburetor, which in turn causes the engine to stall. Because your pressure washer will remain cleaner and clearer for a lot longer if you replace your air filters on a regular basis, you can actually extend the life of your pressure washer.

water pressure washer air filter

As a general rule, it is strongly advised to replace your air filter once a year. After a year, it is still advisable to change the air filter even though it doesn’t seem to be unclean. Additionally, if you see the filter becoming unusually unclean, you may change it more often than that.

The longer the life of your pressure washer, the more effectively it will operate since less dirt and debris will enter your carburetor and engine. Keep in mind that a pressure washer will often shut off if the air filter is continually unclean since the engine and carburetor won’t be receiving enough air.

Simply follow these procedures to change your air filter:

  • Take off the air filter’s lid, then remove the visible foam filters.
  • Take the filters and clean them using a solvent that has a high flash point, such as mineral spirits or paint thinner.
  • Never bend or torque ore the air filter.
  • Squeeze the filter gently when you’re ready to dry it.
  • If you’re changing the filter, first soak it in freshwater, then in motor oil, and then replace it.
  • Close the lid after replacing the air filter with a fresh or cleaned one.

You may be surprised to learn how simple it is to replace the air filter in your pressure washer. Once the lid is removed, the filter is simple to identify, and repositioning it as simple as pie.

Verify the Pressure of Your Pressure Washer Gun

Consider the condition of your pressure gun if your pressure washer continues switching off despite your attempts at the aforementioned fixes. It’s not always the case, but these guns often last as long as the pressure washer does.

Similar to the engine and carburetor, pressure guns contain a variety of parts, some of which may sometimes fail.

The problem is that pressure guns often cost more and need more work to fix than to replace, so you may want to simply replace it if you think that’s the reason your pressure washer keeps turning off.

What Other Issues Could There Be?

If your pressure washer keeps turning off while you’re using it, in addition to checking for the aforementioned issues, you may also look for the following:

  • The O-ring or the spring, shaft, piston, or unloader valve
  • the potential need to replace the wand screens
  • The spark plug may need to be unplugged or cleaned.
  • Possible adjustments to the air pressure

The choke position, could need to be disabled if your engine is smoking
The reality is that a lot of different things might occur that cause your gas pressure washer to cut off repeatedly.

Although it might be difficult, as you are more acquainted with the many components of the pressure washer, it is a little bit simpler to pinpoint the issue.

If you bought a cheap pressure washer and it has several issues, it could be simpler to get a new one.

Final Remarks

The bad news is that your pressure washer will probably periodically turn off without warning. The good news is that most of the time, the issue can be resolved with a little knowledge and a typical toolbox from around the home.

Regular inspections and replacements of air and oil filters, along with making sure they are still clean and clear of dirt, are required. In other words, regular maintenance may maintain the pressure washer in outstanding shape, thus lowering the possibility that you’ll have issues.

In the event that everything else fails, you may always consult professionals at a home improvement store, the shop where you bought the pressure washer or YouTube for some instructive repair videos.
