Pressure Washer Lost Pressure When Trigger Pulled

Sometimes a tiny problem throws us into suffering. Although pressure washer loss is a common problem, it is often caused by a minor cause. This problem occurs in almost all types of pressure washers. If there is inlet plumbing air leakage in your pressure washer machine, it is normal for the machine to shut down when the washer trigger is pulled. When you don’t want to repair it yourself, the problem will seem complicated. The matter is not so complex, and you can quickly troubleshoot this problem.

Similarly, we understand the cause of pressure loss to be worn. In reality, this idea is not right at once, don’t lose the pressure washer for a specific reason. For whatever cause, we aim to get the pressure washer out of the way. As a result of triggering the pressure washer pool, exactly what causes pressure loss! I will present the details here. Let’s get started –

Pressure Washer Lost Pressure When Trigger Pulled:

A pressure washer is a widely used machine for cleaning houses, gardens, courtyards. Sudden loss of pressure while pulling the trigger is a significant and common problem in a pressure washer machine. The machine loses its pressure when the trigger is pulled for various reasons. Don’t panic; seek the help of an experienced person. Simultaneously, learn how to solve the problem yourself so that you do not have to help anyone else solve such issues later.

Dirty and Improper Nozzle:-

Dirty or clogged nozzles are responsible for low or no pressure when pulling the trigger. Also, damaged and wrong nozzles are equally accountable. If the pressure washer loses its pressure while working or fails to give the desired pressure, the user should first check the nozzle.

If dirt accumulates, clean it with kerosene or any other ingredient. Use a stick or pin to clean the dirt inside the nozzle. If the nozzle does not work correctly even after removing the clogged, replace it with a new one. Make sure the new nozzle matches the machine. Moreover, it is better to replace the damaged nozzle.

If the user is new, it will be difficult to confirm the location of the nozzle. The nozzle is located at the end of the trigger wand of the pressure washer.

Checking The Unloader If It Is Restricted or Not:-

The unloader works in two ways. These are – Flow Actuated and Pressure Actuated. When the pressure washer nozzle does not supply water, the unloader returns it through the bypass. In this way, the unloader prevents wastage of water.

Again, the unloader helps to increase or decrease the water pressure. It works to control the extra pressure on the nozzle.

The pressure washer could not give the desired pressure after pulling the trigger because of the dilapidated unloader. In this case, remove the unloader from the machine. Clean the dirt with a cleaner. A wire brush is most helpful in this case. If it is cracked or harmed in any way, install a new unloader for safety.

Inspecting The Piston:-

Unloader disc/piston is vital for maintaining water flow. The unloader disc/ piston can’t work if there is any violation of its freedom of movement.If there is a difficulty with the plate/piston, remove it from the unloader with a screwdriver or wrench. Remove dirt from disc/piston with necessary material. If the piston does not work appropriately despite cleaning, replace it.

Proper Setting of Pressure Washer Valve:-

Water control depends on the proper setting of the unloader valve. Setting the unloader valve to high pressure can cause the engine to stall, causing low water pressure in the washer. So, arranged according to the correct instructions when setting the valve. Seek the help of an experienced person if needed.

Clogged O-Ring Inspection:-

The dilapidated O-ring cannot supply oil adequately. If the O-ring does not deliver oil properly, the machine cannot work typically. In this situation, it would be more significantto replace the O-ring with a new one.

Pressure Gun Troubleshooting:-

Regular work is disrupted if the pressure gun attached to the unloader leaks or is damaged. When the pressure gun leaks, the water spreads out. The washer loses its pressure while pulling the trigger due to the leakage pressure gun. Close the leak with the necessary material. But it is better to change.

Damaged Pressure Washer Valve:-

A pressure washer machine has different types of valves. The size and kind of work of each valve are different. Notable among these are Inlet and Discharge valves.

The Inlet valve is located in front of the water inlet and protects it from outside dust and dirt. On the other hand, the discharge valve keeps the discharge area free of debris to work seamlessly. If each of these pair valves is broken, it affects the washer’s activity. The machine loses its working capacity.

If the inlet valve is damaged, it reduces the level of water flow. As a result, the washer does not get adequate water and power supply And Due to this, low pressure of water occurs in the washer. Interestingly, when the inlet valve does not work, the plunger drips water towards the discharge valve.

Then, water flows through the discharge valve. Remove the two valves from the machine and check if there is any dust in them. Clean the two valves with a smooth cloth and oil. Please pay attention not to break them while cleaning. Check if the valve spring is broken.

Solution For Inadequate Water Supply:-

Inadequate water supply is one reason why the washer loses its pressure while pulling the pressure trigger. Before removing the trigger, make sure there is enough water in the pump. Often, the washer does not get the expected water even though there is enough water in the pump.

There must be a balance between PSI and GPM to keep water flow at the desired level. PSI and GPM levels are specified in the instructions for each machine separately. Adjust the classes according to the instructions.

Water Flow Rate Issue And Troubleshooting:-

In addition to pressure guns, nozzles, unloader troubles, another trouble is the low water flow rate. Consequently, the water flow rate becomes downward due to an accumulation of dirt in the water flow path. Turn on the water pump to understand this problem. Even if there is enough water, if the water flow rate decreases, It should realize that the water flow path has become dirty. Clean the water flow path with a cleaner.

Inspecting High-Pressure Hose:-

An inappropriate high hose can cause the machine’s stops even after having a high-pressure hose in the machine. The high-pressure hose is not a part of the machine’s direct work, but it simplifies the job by creating pressure in the washer. So use the high hose that is suitable for the device.

Also, if the high hose is clogged or twisted, properly remove the dirt. When it is twists or bends, replace it with a new one. Remove the high-pressure hose from the washer, then clean it.

Quality Of Plunger:-

Some devices are often overlooked or ignored by the user. The user is not at all concerned about the quality of the plunger. Overall it affects the washer. Over time the plunger becomes damaged. Replace with the old one by collecting the suitable plunger for the machine from the market. Contact the manufacturing company if you do not find the appropriate model plunger.

Air Release Troubleshooting:-

The more noticeable problem in the pressure washer machine when pulling the trigger is the air getting stuck in the pump. The trapped air slowly heats the pump. In this situation, the pump cannot supply water adequately. To exhale air, first, turn off the engine, then remove the hoses behind the pump.

Now reattach the garden hose. Please turn on the pump and keep it like this for 5 to 6 minutes. Now put the other one on and start the engine and do the usual cleaning activities.

Checking Water Inlet Filter:-

When the water inlet filter is clogged, the pressure washer loses its pressure. The user must remove and clean the filter every 4-5 usage intervals. Clogged filters block the normal flow of water and reduce water pressure in the washer. The filter is a bit brittle, so be careful when removing it from the washer. Remove dirt by rubbing with a soft, scaly brush. And if the filter is broken or damaged for any other reason, please change it.

Instructions For Using Fuel:-

Always be careful when using fuel. Older fuels lose their quality over time, making the energy thicker and thicker through evaporation. Use new fuel by removing the fuel inside the tank that has been in the tank for more than one month. Old power will cause problems step by step. That will prevent the washer from creating adequate pressure. Always use pure fuel if you want to get the desired water flow.

It is foolish to think that only old fuel is a problem in pressure washers. Sometimes there is a problem with new fuel. The question may be, How?

You poured pure fuel into the tank, but your fuel filter was full of dirt. So, all the dirt in the filter mixed with the fuel and contaminated the fuel. So make sure the filter is clean before pouring the fuel. Also, keep the fuel cap on properly.

Conclusion: –

What could be the problem if you pull the trigger of your pressure washer machine! We have discussed this in detail. It is crucial that you notice the exact cause and then take steps to solve it. An Old-Worn nozzle is one of the leading causes of pressure loss, just as well – a blocked discharge valve can be one of the leading causes of this problem. Hopefully, you can now solve the problem of pressure loss caused by your valuable pressure washer’s trigger pool. Of course, to keep your laundry running, it is vital to fix the equipment yourself.
