Run the pressure washer for a few minutes … then it stops.
Humming sound … sounds like the motor is jammed or something like that.

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 :

Water leaking from a loose connection can cause the unit to cycle on and off. Verify if the pressure hose has an O-ring at the connection. If missing, this will also cause the unit to cycle on and off. While the unit is running look for any water leaks that may cause the unit to turn back on.
A clogged carburetor is most commonly caused by leaving fuel in the pressure washer for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to run stall.
If your pressure washer is refusing to work or even turn on, the culprit could potentially be the power switches. Most pressure washers use two micro switches that disconnect both the live and neutral connections between the supply and the motor. These switches can jam cutting the power out from reaching the motor.
If the spark arrestor is dirty or damaged, it can cause the engine to stall. To clean the spark arrestor, you will need to remove it from the pressure washer and use a wire brush to remove any build-up. Once the spark arrestor is clean, you can reattach it and try starting the power washer again.
Some of the most common faults that will make your washer stop mid cycle include thermostat failure, problems filling up with water for the rinse cycle, or even pump problems that prevent your washer from draining. One thing that you can check yourself is the lid switch.
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.
Clogged carburetors or air filters can cause a pressure washer not to start. If your pressure washer won`t start, you can also check for a clogged carburetor or air filter.
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.
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.
Clean out the machine and make sure all of the components are clear before using it again. Finally, check the oil level in the machine. If the oil is low, this can cause overheating. Add more oil as needed and be sure to use the proper type of oil for your specific model of pressure washer.
If you find that your washer is routinely stopping during the rinse cycle, then it may be caused by a faulty water inlet valve. As it stops during the rinse cycle, the washer will stop in the middle of the wash. It will not advance likely because it reads that the water level is too low.
Give Your Pressure Washer a Break

No matter how powerful your pressure washer might be, it`s never a good idea to leave your machine running for too long because doing so will increase the risk that it will overheat. Instead, most professionals suggest using a pressure washer in intervals of three to five minutes.

It depends on the pressure washing equipment you purchase. New pressure washers will be rated with a number of hours they should last. For example, if it is rated 500 hours and you use it fewer than 50 hours throughout the year then it will last you more than ten years as long as you keep it well maintained.

If the pressure washer trips the fuse board or blows the electrics in your home, make sure there`s no water in the switch or the other electrical items – and again examine the capacitor if your model carries one.

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
