Pressure Washer Storage Hose Reel

When I start the pressure washer, it runs fine on low pressure. However after about 3-5 seconds of high pressure washing, the engine dies.
Experienced gardeners share their insights in answering this question :
The engine requires more fuel at higher loads. If unit sat up for some time the jets in carbureator may have become partially plugged due to varnishing. If this is the case, the easiest fix, is to add ‘Sea Foam’ fuel system cleaner to gas tank. engine may have to run several minutes for this to work. I reccomend tripling the dosage amount reccomended on the label. This should also resolve the problem if fuel starvation is caused by ‘sticking needle and seat’ problems. If engine stalls with an abrubt clunk, then unloader problems may be responsible. I unit sat up for a long-long time, you may be better off removing the carbureator and rebuild it or have it rebuilt professionally.

Check for leaks

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.

This typically indicates that the machine is losing pressure somewhere, such as a leak in one of the lines or inside the case of the machine. The machine tries to compensate for this leak by running harder or more often than it should.
The Science of Hose Lengths

Assuming a best-case scenario – working on flat ground and normal operating conditions – you typically won`t lose much pressure as you increase the length of hose that you use. For instance, on a 3/8-inch hose with a 3 gallon/minute flow, the loss of pressure per 100 feet is about 50 PSI.

Water leaks and inconsistent behavior are also signs of a potential failure in the near future. González: The typical signal when there is an unloader malfunction is a reduction of flow through the nozzle, which results in pressure loss. Dean: Typical symptom of an unloader failure is a sudden smooth pressure loss.
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.
Problem: The pressure washer cuts out.

If your machine cuts out occasionally, it could be because you are using an electric extension cable. Extension cables must always be 13 amp constant rating and no longer than 10 metres. Please check your operating instructions for correct specifications.

Without an unloader valve, the water pressure continues to build up in the nozzle, potentially causing a very unsafe situation. The increase in pressure – without an unloader valve to regulate it – could cause the water pressure to go over the PSI limit, potentially damaging your pressure washer`s pump.
And when a PRV fails, it can lead to an explosion. Damaged equipment, disrupted work flow, and even injury may result. Why take that risk when you can easily tell whether or not your pressure relief valve needs replacing or repair.
The vast majority of pressure washer spray guns feature a trigger lock that can be used when you need to step away from the pressure washer. Utilizing the trigger lock will prevent any unintentional spraying and accidents.

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.

Need help in getting Honda engine on NorthStar pressure washer to run.
ANSWER : Could be low water pressure I have found.Also, I purchased a can of “stuff” at Lowes today which allows you to circulate a liquid substance which lubricates the pressure pump….the pump could be frozen up…I have a rotating nozzle which I bought…and it had frozen up…this stuff works

My pressure washer will start for a second and then shuts down. I just bought it from a friend and don,t think the springs to the govner are right but not sure.would like a skicamitc of the engine or manual so i can see if they are right
ANSWER : When you start your engine open wand trigger this will probably allow you to get the engine warmed up and I think it’ll work for you it used to work for us .

Honda powwer boss 3000-whenyoupull the handale to spray it kills the engine
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.

ANSWER : Probably a clogged carb from sitting all winter with fuel it it.

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

Pressure washer shuts off overheating
ANSWER : If you are using an extension cord this will happen. If using an extension cord make sure it is a 12ga.If you are not using an extension cord then it could be a bad motor or low voltage from the source.
