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 :
No water jet from the nozzle of the pressure washer > check if the nozzle itself is not clogged – if this is the case, clean or replace it. Also check if the water mains tap is correctly opened and that there is no problem in the flow of the suction hose.
Check to make sure there is water in the fresh water tank. If it is empty, please remove it and fill it with cold or lukewarm water and then replace.
Why has my water blaster lost pressure? A common cause for lost water pressure is when the nozzle at the end of the trigger-wand becomes worn or blocked. An uncommon spray pattern may be an indication that there is debris blocking the nozzle.
A clogged filter will not allow any water to be released. The Fix: Remove and inspect the filter for a blockage. If the filter is dirty, remove any buildup and reconnect to the floor scrubber. Once free of debris, the machine should begin to distribute water again.
PLEASE NOTE: You should always press the RESET button on the GFCI before using the pressure washer.
It Can Harm The Unit
Without water to cool and lubricate it, the pump will work harder than it should, causing it to wear down quickly. This can happen even with just a few seconds of running the pressure washer without the water being turned on. However, the pump is not the only part that takes damage.
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.

No pressure Pump reassembly. I purchased a new pump and installed it. Got machine back together and I’m not getting any pressure. What would be the signs if I don’t have the shaft key in properly? Or any other suggestions?
Water comes out of nozzle with pressure for a quick second then no pressure, just water. This is a brand new pump so was curious if I installed it wrong. Wondering before taking it apart again.

Started washer, heard ‘pop’, water started coming out of bottom
ANSWER : Thats not good. Sounds like the seal blew out. Inside the unit there are seals that seal up the parts where they are bolted together. Also there is the pressure connection that could have blown out as well. To determine which is the problem you will need to dissassemble it.

I have had 3 Karcher pressure washers all experience the same problem and so have two of my neighbors. Our area has very hard water and it causes problems with the washer not bringing up the pressure when the trigger is pulled (or surges up and down) and the nozzles clogging, etc. The service repair facilities cannot tell me how to prevent this. Many attempts to contact Karcher for advice have been ignored. I have been thinking that perhaps running the engine for a few seconds with no hoses attached and shooting WD-40 as a water displacer into the hose inlet might work. Do you have any recommendations or suggestions? My most recent purchase of a Honda pressure washer lasted only two uses and the pump froze up.
ANSWER : If your water is that hard (and it appears it is) WD40 will NOT solve the problem. You should look into a water softener. However, chances are that a small, inexpensive model will not have the flow capacity required for a pressure washer. You’ll likely need to look at a larger, whole-house model.
Use vinegar to through the machine’s “soap” dispenser to break up the hard water deposits or a heavier solvent such as CLR which is available at most retail outlets.
