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 :
You may need to rebuild or replace the pump assembly. If the pump is more than a few years old, and you use the pressure washer fairly often, replace the pump assembly. If the pump is relatively new, and you don`t use the pressure washer often, either rebuild the pump assembly or replace the pump seals.
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.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
Moreover, the longevity of a pressure washer is significantly increased by our regular maintenance service. It is a cost-effective method of keeping Karcher repairs to a minimum.
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.
Little Or No Water Pressure
Begin isolating the problem by hooking a water hose to the washer`s inlet and turning it on. If water flows out the outlet, you know water is cycling through. If not, chances are your inlet filter is clogged. Remove and clean it, and you should be good to go.
The Fuse. If the pressure washer does not start, then the first thing to check is the fuse in the plug. The reading you`re looking for is the same as it would be when connecting the two probes of the multimeter together (as you can see in the example of this video, this fuse is actually fine).
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.

I have a karcher 2.o1 pressure washer does not work when i turn the water on, if i turn the water off it works, cant figure it help , help please
Please try without the high pressure lance on. If this works then you may have a blocked jet in the lance.
The karcher works well, but when you stop spraying. The pump cycles on and off.
This is a cooling feature. There is a thermal coupler to allow the cool water to cycle and cool off the pump.thank you Joe
Oil is coming out of the lance end when in use . it doesn’t come out all the time every 30 seconds or so . it comes out whether on hot or cold . karcher hds550c
Sounds like the seals & o’rings are faulty.get the model number of pump and purchase a kit for the pump.replace all seals and o’ rings.this will stop the oil from the pump going through the nozzle.
Karcher 4.91 checked fuse that is ok but no power
Check and see if you are getting power to the on/off swith. These switches have been known to go bad. Also, check the Ground fault breaker in the plug. Let me know how you make out.

Make sure that while you are running your pressure washer, other machines that pull
large volumes of water like a dishwasher or washing machine are not running. check and make sure
the hose you have tied to the pressure washer is not collapsing or has any kinks in it.
check the filter where your water hose ties in to your pressure washer, make sure it
is clean and does not have any debris or hardwater buildup, clean the tip at the tip of
the wand. if it is reduced in size by hardwater buildup, will not work properly, good luck!
