Adjust the screw on the pressure regulator on the high pressure hose is one way The other is to check the nozzle for obstructions. The problem is that there is insufficient flow from the nozzle so the regulator valve is trying to cycle between cut off and working pressure.. The regulator is set at factory for a particular size nozzle and anything that alters that ratio will cause you problem. The screw on the regulator has some fine adjustment to allow for slight changes. Any impurities in the water supply will tend to block the nozzle affecting the regulator .
How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Surging occurs when the pressure is fine and then weakens. It is caused when the flow rate for the pump cannot be supported by the water supply. Problems can mount from there so it is important that it is dealt with as soon as possible.
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.
If the machine is pulsing when on standby, is the garden hose supplying the pressure washer fully uncoiled? If the machine is pulsing whilst in use, it may be that the accessory you are using has a blockage. Clear by soaking the accessory in warm soapy water and then rinsing out under the tap.
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.
Usually, well water pulsates when there isn`t enough air pressure in the tank. The two parts that regulate this pressure are the electric pressure switch and the internal air bladder inside the water tank. If either of them is malfunctioning, this can cause the water from your taps to pulsate rather than flow steadily.
The number one cause of pump surge or pulsing is your classic air leak. The more pressure your pump creates, the easier it is for air to get sucked through even the smallest leaks. And since air poses less resistance than water, it will get sucked by the pump instead of water, causing the pump to pulse.
If your pressure washer starts and runs fine, but there`s no pressure or no water coming from the pump, it could be a clogged wand, hose or inlet filter. Fortunately, this is an easy pressure washer problem to repair. Begin isolating the problem by hooking a water hose to the washer`s inlet and turning it on.
What Is the Unloader Valve? A compressor unloader valve is a small part, typically measuring approximately 4-5 inches in length and width. It performs the critical function of releasing trapped air inside the tank, enabling the motor to restart.
For this reason you should not let your pressure washer idle, not spraying water for more than a few minutes. Without cooling the pump head the temperature will begin to climb to 200+ degrees. When it gets that hot, water seals and o-rings soften and wear quickly. Valves can be distorted and warp.
Simply turn off your pressure washer and disconnect the hose. Keep your garden hose attached and allow water to run through it for 20-30 seconds. Turn off your garden hose and reassemble. Try using your pressure washer as normal and see if that fixes the pulsing.
Pressure may decrease if your packing is worn out or if there are abrasives or severe cavitation (bubbles) in the pumped fluids. This can be caused by an inadequate amount of water and/or a lack of proper filtration. To fix, install the proper filter.
The pressure washer vibrates excessively and is too much noisy > the water inlet filter may be responsible for it: if dirty, simply clean it.

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.

Pulsating when idle
ANSWER : The motor doesn’t pulsate when you are spraying and pulsattes when not spraying is normal otherwise the pressure will just keep building and burn out the pump. However, if you are not using the sprayer right away then the unit should be shut off until your ready to start again.

ANSWER : Sounds like the unloader (regulator). Try removing the nozzle, the pull the trigger with the engine running. If motor is still running then it could be the Unloader malfunctioning. If you require a new one try a bypass system for the unloader. The bypass will help save the life of the unloader.

Kranzle electric washer will not suck up soap
ANSWER : Hi, if it has a chemical injector on the machine then the pressure at the lance will have to be lowered for it to pull in soap. it works on a similar principle to how carburetors on cars pull in fuel, bernouli principle. high pressure at one side of an orifice going to low pressure at the other side which causes a negative pressure ( vacuum) which should pull in the soap. there should be a non return valve at the orifice (hole) which prevents the water back feeding into the soap container, it is quite common for this valve to get stuck, it is just a ball, spring and o ring , and the ball sticks to the o ring. if it is this system then take the soap pick up pipe off the injector and just push the ball off it’s seat with a bit of wire.If it is a high pressure soap system then that is different, but they usually work with an injector in my experience.try taking the high pressure hose off the front off the machine and running it, if it has an injector on it it should pull in plenty off soap.hope this helps ,andy
