A common cause for lost water pressure is when the nozzle at the end of the trigger-wand becomes worn or plugged. An uncommon spray pattern may be an indication that there is debris blocking the nozzle. Nozzles that are wearing will usually cause a gradual loss in pressure, as opposed to happening suddenly.
If your pressure washer shuts off when the trigger is released, it has a problem with the unloader valve. There are a few issues with your unloading valve that causing stalling the engine pump.
One may also ask, what causes pressure washer to smoke? Smoke blows from the exhaust if the engine is overfilled with oil.

An improper fuel/air mix can also cause the engine to smoke.
Beside above, does my pressure washer pump need oil?
Pressure washer water pumps need relatively low oil recommended by the manufacturer, as specified in the owner’s manual. (Purchase pre-measured bottles of pump oil for water pumps without dipsticks.) Never use special oil additives or detergents, unless specified in the owner’s manual.
Do all pressure washers have unloader valves?
An unloader valve is the component of a pressure washer that allows the pump to bypass the flow of water back to the pump while the spray gun is not being used. Most unloader valves also act as a pressure regulator for the output pressure of the pump. Overloading the pump will shorten the life of the pump.
Can you repair pressure washer pump?
Decision Between Repair and Replacement Wobble pumps are economically but not designed to repair them. So, change the entire washer without thinking. If your pump is an axial cam pump, then you have the option to change the damaged parts or repair them or replace the pump. Repairing may take less than 2 hours.
Why does my pressure washer keep stalling?

Why would a pressure washer stop working?
The most common cause of low pressure for a pressure washer is an incorrect nozzle or a nozzle that has worn out. Make sure there is water coming to the equipment properly as well – a hose that is going up a hill will delay water pressure from arriving. Replace any worn out or broken nozzles when they are discovered.
Can I start my pressure washer without water?
Although you can start a pressure washer without water, it is not advisable to do it. The pumps job is to take in water from the supply hose and push it out through the nozzle. The pump is designed to operate with water flowing through it. The water helps to lubricate the pump and help to keep it cool.
How long can you run a power washer?
To avoid damaging the pump: Never run a washer longer than three to five minutes (depending on the model) while the trigger is off. With the washer running and the trigger locked “off,” adjust pressure and spray settings, or insert nozzle tips in the spray wand. Now the washer is ready to use.
What causes a pressure washer to pulsate?
My Pressure Washer Is Pulsating This issue is almost always caused because of a dirty inlet or discharge valve. If your inlet and discharge valves are clean, then the plunger is the likely the cause of the pulsating, especially if you have low pressure while this is happening.
