Pressure washers can be tedious to work with, at times they won’t work smoothly or may not even start! Such situations can be pretty irritating especially if you don’t know how to fix your pressure washer.
If you want to find solutions for such problems, it is essential to understand how does a pressure washer work.
If you haven’t bought a pressure washers yet then you must check out this detailed guide on top 10 best pressure washers.
Every pressure washer is different from the other. Different models pack different features, but all of them operate on the same principles. The central principle is that the water cannot be compressed and therefore when the water is pressurized, it pushes out in every direction. The very same principle is used in pressure washers to create a high-pressure stream of water that can be controlled by the operator.
Two essentials of a pressure washer are the power source and the pump. The power source can be an electric motor or a gasoline engine. As far as the pump is concerned, there are two types of the pump as well, it can either be an axial pump or a triplex pump.
Since you now know about the major components of a pressure washer, it is vital to understand how they work.
The engine of a pressure washer runs in a fascinating way. A four cycled engine is used in most of the pressure washers to drive the pump. The four cycled engine works on gasoline and has a separate sump for oil similar to an automobile engine.
The operator has to set the start switch on run position and needs to pull the starter rope to run the washer. When the rope is pulled, it engages the drive cup on the flywheel and rotates the crankshaft.
The rotation of crankshaft results in the up and down movement of the piston and eventually the ignition process begins. The flywheel has magnets attached to it, and therefore its movement creates a magnetic field which converts the fuel into electricity.
Listed down below are some common problems that one can face while using a pressure washer:
Pressure washer won’t start
If the pressure washer doesn’t start, then the likely cause is a defective spark plug, or the carburetor is restricting the air and fuel mixer from entering the engine. In this case, the carburetor can be cleaned, but most of the time it needs to be replaced.
Engine stops after a few seconds
If your engine is not working correctly or stops after a few seconds, then try changing the oil. Keep in mind, that the pressure washer is designed to run on gasoline with a maximum of 10% of ethanol. Gasoline with higher levels of ethanol can be corrosive and may attract water which can cause running or starting problems in the engine.
Pressure washer runs poorly
The problem mostly starts with the engine and most of the time it is due to the fuel. Lousy gasoline may damage the whole fuel system. Always store the gasoline in a clean sealed plastic container away from direct sunlight and if required consider adding a fuel stabilizer to make sure that it maintains its quality.
Water Leaks in Pressure Washer
Leakage of water from a pressure washer is not usually a problem. If the pressure washer is kept running for an extended period without activating the trigger, the water circulating inside the pump becomes hot, and it gets discharged through a thermal relief valve to let the cooler water enter inside. So, this leakage of water is a mere function of the washer to continue smooth working.
No pressure in Pressure Washer
The main reason for the reduced pressure in the washer is insufficient water supply. But many times, the problem can be with the pump, the higher the engine speed, the more pressure the machine can produce. Also attempting to run the washer without oil can result in pump failing. You can use a product called pump saver to save your washer from experiencing this problem.
To ensure smooth functioning of the pressure washer, it is crucial to follow the manufacturer’s recommendations.
