There is a high pressure valve that is broken on the inside of the machine that needs to be replaced. If you gave me the model number I could look it up and tell you how to take it apart and get the parts that you need.
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 :
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.
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.
Using an old, worn-out nozzle is a common cause of lost pressure, and also has one of the simplest fixes. All you need to do is replace the nozzle and make sure you`re using the proper size. Don`t go by the color of the nozzle, make sure you check the orifice size.
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.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter. If your pressure gauge reading was low, make slight adjustments to your regulator.
Once your pressure washer and water source are turned OFF and you are unable to disconnect your hoses from the pump and gun it is generally due to the pressure that is still inside of the machine. To relieve this pressure simply squeeze the trigger to release any water and then try disconnecting hoses again.
DON`T Let the Machine Run Too Long Without Pulling the Trigger. Pressure washers operate under pressure, and that pressure needs to be released by pulling the trigger. If you let the machine run for two minutes or longer without spraying water, then you could damage the pump.

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?

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.

Water shoots out back instead of hose when engine is started
ANSWER : Problem description is very vague. The only thing for sure is that water seems to be coming out at the wrong place. Common problem could be related to improper storage. All water, or as much as possible, should be removed from the pump before cold weather storage. Many pumps are made from cast aluminum, which can easily crack or split from winter storage if enough water remained in the system during freezing weather. If it is an external part, such as the inlet or outlet tube, check the manufacturer for a replacement part, since these are sometimes replaceable. Another possibility could be a loose fitting on the pump. There is also an “O” ring on the connection to the outlet tube on the hose end. Check to make sure it is still there and not broken or crushed. Many hardware stores have “O” ring kits. It would be helpfull if you could pinpoint the source of the leak. Always separate the gun and hose from the pressure washer to drain out any remaining water. Freezing isn’t the only problem since you could have hard water that will leave mineral deposits when the water evaporates. This, according to some manufacturers will not be covered by the warrantee so I guess is should be something to avoid. Good Luck.

No high pressure. has been a consistant problem for a while. Was able to get high pressure to “kick-in” before by removing nozzle, squeezing trigger to “prime” high pressure, then quickly put nozzle back in then it would work. now it doesn’t work at all.

Craftsman Pressure washer will not spray
ANSWER : Your not missing anything, check the pump, they tend to go bad over time and may need replacing. The pump provides the pressure as well as the suction for the whole process, pulling water from the hose or tank and pushing it forcefully through the pressure washer line. If the motor is running and you have the water going through the line and to the pump, and no water is coming out, my guess would be the pump.
