The number one cause of low or no pressure when using a pressure washer is a blocked or worn nozzle. Blocked nozzles will prevent water from escaping, while a worn nozzle will allow too much water to pass through, causing the pressure to drop.
Worn nozzle(s) are the most frequent cause of low pressure. Never adjust the pressure regulating valve to compensate for worn nozzles. This will result in over-pressurization and possible damage to the pump. Replace nozzle(s) with the proper size when pressure drops or on a regular maintenance schedule.
How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
There could be small leaks, holes, or tears in your garden hose or high-pressure hose that are causing your pressure washer to lose pressure when you pull the trigger. If you find leaks, plug the holes or replace the hose, which should solve your pressure issues.
A pressure washer forces water through a small opening to create pressure and cleaning power. This process is analogous to putting your finger over the opening of a garden hose to increase the pressure.
First, you can increase the fluid flow rate into the pump. This will increase the pressure on the fluid, and therefore increase the output pressure of the pump. Second, you can increase the displacement of the pump.
The pump is not producing the rated flow or head:
The clearance between the impeller and casing is excessive – adjust the impeller clearance. The suction head is insufficient – ensure the suction line valve is fully open and the line unobstructed. If the impeller is worn or broken – inspect and replace.
If it takes two minutes or less, you`ll be fine, since most pressure washers need 2-1/2 gallon per minute to work. To ensure that water circulates unobstructed through the system, check the water inlet filter or screen and clean it of debris. Also, make sure the garden and pressure hoses are kink free.

1750 psi Electric Pressure Washer: My pressure washer is losing pressure and is pulsa…
ANSWER : If the pressure washer is pulsating then that is a sign of check valve failure. You may be able to clean of replace the check valves. Replacing the head is the wrong way to go. This is completely unnecessary. If you can tell me the model number of your pressure washer then I can assist you better in pointing you in the right direction.
