Pressure Washer Shuts off When Trigger is Pulled

If your pressure washer shuts off when you pulled the trigger, there are a few things that could be causing the problem. One possibility is that the water supply to your power washing machine is not turned on all the way. Another possibility is that the pump has overheated and needs to cool down before it will work again.

If neither of these solutions solve the problem, then it is likely that there is something wrong with the pressure washer itself and you will need to contact a professional for repairs.

If you’re having trouble with your pressure washer shutting off when you pull the trigger, there are a few things you can check. First, make sure that the water supply to the machine is turned on all the way. If it’s not, the pump will shut off when it doesn’t have enough water to work with.

Next, check the pressure relief valve to see if it’s open. If it’s not, that could be why your machine is shutting off. Finally, take a look at the unloader valve to see if it’s working properly.

If it’s not, that could also be causing your machine to shut down. With a little troubleshooting, you should be able to get your pressure washer up and running again in no time!

Pressure Washer Unloader Valve Symptoms

If your pressure washer is having trouble starting up, or if it seems like the pump isn’t building pressure, there’s a good chance that the unloader valve is the culprit. The unloader valve is responsible for diverting water flow from the pump when the trigger isn’t being pulled, and it also regulates how much water flows through the pump. Over time, these valves can become gummed up with dirt and debris, which can cause all sorts of problems.

Fortunately, diagnosing and fixing an unloader valve issue is relatively simple. So, if your pressure washer isn’t performing like it used to, read on!

One of the most common signs that something is wrong with your unloader valve is that your pressure washer will have trouble starting up. If you pull the trigger and nothing happens, or if there’s a significant delay before water starts flowing, chances are good that there’s an issue with the unloader valve. Another common symptom is loss of pressure while in use.

If you notice that your washer doesn’t seem to be generating as much pressure as it used to – even when using a high-pressure nozzle – then again, the unloader valve may be to blame. Fortunately, cleaning or replacing an unloader valve is a fairly straightforward process. First things first: shut off your pressure washer and disconnect it from any power source (including extension cords).

Once it’s safe to work on, remove any covers or panels so you can access the valves. You may need a screwdriver or other tools to do this; consult your owner’s manual for specific instructions. Once you have access to the valves themselves, take a look inside and see if there’s any build-up of dirt or debris.

Pressure Washer Unloader Valve Adjustment

If you have a pressure washer, you know that one of the most important parts is the unloader valve. This valve helps to regulate the amount of water pressure that is released from the pump. If the unloader valve is not working properly, it can cause your pressure washer to lose power or even stop working altogether.

Luckily, adjusting the unloader valve on your pressure washer is a relatively easy task that you can do yourself. First, locate the unloader valve on your pressure washer. It is typically located near the pump or on the back of the unit.

Once you have found it, take a look at the adjustment knob or screw. This will be what you use to adjust the valve. Next, start your pressure washer and let it run for a few minutes so that everything gets warmed up.

Then, turn off the unit and release any remaining pressure in the hose by pulling back on the trigger until no water comes out. Now it’s time to adjust the unloader valve itself. For most models, you will want to turn clockwise to increase pressure and counterclockwise to decrease pressure.

Turn the knob or screw until you reach your desired level of water pressure – keep in mind that too much pressure can damage your equipment so err on the side of caution if you’re unsure! After making your adjustments, simply turn on your pressure washer and test it out to make sure everything is working as it should be. That’s all there is to adjusting an unloader valve!

Pressure Washer Stalls under Load

If your pressure washer stalls under load, there are a few things you can check to try and remedy the problem. First, make sure that the engine is getting enough oil. If it isn’t, add more oil until the level is full.

Next, check the air filter and clean or replace it if necessary. Finally, inspect the spark plug and replace it if it’s damaged. If these troubleshooting tips don’t fix the problem, take your pressure washer to a qualified repair person for further diagnosis.

Troy Bilt Pressure Washer Unloader Valve

If your Troy-Bilt pressure washer isn’t working as it should, one possible issue is the unloader valve. This valve is responsible for regulating the amount of water that flows through the pump. If it becomes damaged or clogged, it can cause a variety of problems with your pressure washer.


The unloader valve on a Troy-Bilt pressure washer is located between the pump and trigger gun. Its purpose is to relieve pressure when the trigger gun is not being used. This prevents damage to the pump from over pressurization.

When you pull the trigger on your pressure washer, water flow is increased and directed through the nozzle at high pressure. When you release the trigger, water flow decreases and goes back through the unloader valve into low-pressure mode. The unloader valve then releases any remaining water in the pump so that it doesn’t build up too much pressure and damage the pump components.

Troubleshooting a Faulty Unloader Valve

Troubleshooting a Faulty Unloader Valve

There are several symptoms that can indicate a problem with your pressure washer’s unloader valve:

1· Low water output – If there’s not enough water flowing through your machine, it could be because the unloader valve is stuck in the open position.

This will cause low water flow and reduced performance from your machine overall.

2· Erratic or pulsating spray – If your machine’s spray is erratic or pulsing, it could be due to an obstruction in the unloader valve itself. This can happen if dirt or debris gets lodged in the valve, preventing it from sealing properly.


3· Leaking hose – A leaking hose is another symptom of an obstructed or faulty unloader valve. Water will leak out of either end of the hose when this happens – usually at high pressures – which can be dangerous for you and those around you.

4· Machine won’t start – In some cases, a faulty unloader valve can prevent your pressure washer from starting up at all!

New Pressure Washer Keeps Shutting off

If your new pressure washer keeps shutting off, there are a few things you can check to troubleshoot the issue. First, make sure that the oil level is full and that the oil is fresh. If the oil is old or low, it could be causing the engine to overheat and shut down.

Next, check the air filter to see if it needs to be cleaned or replaced. A dirty air filter can also cause the engine to overheat. Finally, make sure that there is enough fuel in the tank.

If the tank is empty or nearly empty, it could be causing the engine to stall. If you still can’t get your pressure washer to stay running, take it back to the store where you bought it for further assistance.

Craftsman Power Washer Keeps Shutting off

If you own a Craftsman power washer, you may have experienced the frustrating problem of it shutting off unexpectedly. This can be a real pain, especially if you’re in the middle of using it to clean something. Here’s what you need to know about this problem and how to fix it.

The most likely cause of your power washer shutting off is that the thermal relief valve is tripping. This valve is designed to release pressure if the temperature gets too high, which can happen if the pump runs for too long without water flowing through it. To fix this, simply turn off the power washer and let it cool down for a few minutes before restarting it.

If the problem persists, you may need to replace the thermal relief valve. Another possible cause of your power washer shutting off is that the inlet water filter is clogged. This filter keeps dirt and debris from getting into the pump and causing damage.

To clean or replace the filter, consult your owner’s manual. If your power washer keeps shutting off, don’t despair! With a little troubleshooting, you should be able to identify and fix the problem quickly so you can get back to using your power washer without interruption.

Dewalt Pressure Washer Keeps Shutting off

If you’re having issues with your Dewalt pressure washer shutting off, there are a few things you can check. First, make sure that the water supply is turned on and that there is enough water pressure. If the problem persists, it could be an issue with the pump or motor.

You’ll need to contact a qualified service technician to diagnose and repair the problem.

Pressure Washer Throttle Problems

If you’re having trouble with your pressure washer throttle, there are a few things you can check. First, make sure the throttle is in the correct position. If it’s not, adjust it and see if that fixes the problem.

If not, then you may need to clean or replace the throttle itself. There are a few different types of pressure washer throttles, so you’ll need to identify which type you have before proceeding. The most common type is the trigger throttle, which is located on the handle of the pressure washer.

To clean this type of throttle, simply remove it from the handle and wipe away any dirt or debris that’s accumulated on it. If your pressure washer has a lever throttle, you’ll need to access it from underneath the machine. Once you’ve located it, clean it off with a cloth or brush.

If neither of these solutions works, then you may need to replace your pressure washer’s throttle assembly.

Why Does My Pressure Washer Keep Stalling Out?

If your pressure washer is stalling out, it could be for a number of reasons. Here are some possible causes:

1. The engine isn’t getting enough oil. Check the oil level and make sure it’s full. If it’s low, add more oil and try again.

2. The air filter is dirty and needs to be replaced. A dirty air filter can restrict air flow to the engine, causing it to stall out.

3. The spark plug may be fouled or damaged and needs to be replaced. A damaged or fouled spark plug can prevent the engine from starting or cause it to stall out.

4. There may be water in the gas tank. Water in the gas will dilute the fuel and can cause the engine to stall out. Drain the gas tank and refill with fresh gasoline.

How Do You Fix a Pressure Washer Unloader Valve?

If your pressure washer unloader valve is not working properly, there are a few things you can do to try and fix it. First, check to see if the valve is dirty or clogged. If so, clean it with a brush or compressed air.

Next, check the O-ring and replace it if necessary. Finally, check the spring for corrosion or damage and replace it if needed.

Why Does My Pressure Washer Surge When Trigger Released?

If your pressure washer is surging when you release the trigger, there are a few possible causes. First, check to see if the unloader valve is stuck in the “on” position. If it is, simply turn it to the “off” position and see if that fixes the problem.

If not, there could be an issue with the pump itself. It’s possible that a seals or gaskets are worn out, causing oil to leak into the pump and causing it to surge. You’ll need to take your pressure washer to a repair shop to have it looked at if this is the case.

Finally, it’s also possible that there is something blocking the nozzle of your pressure washer. This can cause water to back up and surge when you release the trigger. Again, simply clear any debris from the nozzle and see if that solves the problem.
