The weekend was preparing to flush the driveway, and the pressure washer suddenly went on strike, which was really maddening. However, don’t rush to pay 1000 or 2000 yuan for repair. More than 90% of such sudden failures are 3 minor problems: air enters the water pipe, the unloading valve is stuck, or the carburetor is pasted by the long-term gasoline.<\/p>\n\n\n\n

As long as you find a 10mm wrench in the garage and follow the steps below, you can bring the machine back to life in more than ten minutes, saving a lot of money.<\/p>\n\n\n\n

3-Minute Fault Fast Screening: Old Master’s “P.A.P” Troubleshooting Method<\/h2>\n\n\n\n

No more blind jerking of the starter rope with your eyes closed. The mechanic usually uses these 3 steps to find out the crux in three minutes:<\/p>\n\n\n\n

P-Power (power end\/engine and motor): Can the machine normally fire and not stall? If the idling speed is quite stable, but the engine can’t breathe or even stall 1 the trigger of the water gun is pulled, the problem is probably in the fuel supply system, that is, the main measuring hole of the carburetor is blocked.<\/p>\n\n\n\n

A – Air (gas path and water inlet): Does the water outlet from the nozzle 1 a 1 and accompanied by a crackling jet sound? This is a typical water intake. Water is incompressible, but bubbles buffer the pressure, there is residual air in the pipeline, and the water pressure cannot go up at all.<\/p>\n\n\n\n

P-Pump (pump body pressure): the engine roars vigorously, but the water from the muzzle is as soft as the ordinary faucet? This is because the unloading valve on the high-pressure pump is stuck in the bypass pressure relief state.<\/p>\n\n\n\n

Quick Repair Methods For 7 Common Malfunctions<\/h2>\n\n\n\n

Technique 1: Bleed air from the piping (eliminate pump cavitation)<\/h3>\n\n\n\n

Air trapped in the garden hose can enter the high-pressure pump and cause \u201ccavitation.\u201d Bubbles inside the pump head act like a spring like shock absorber, causing the internal plunger to be unable to build any pressure\u2014no matter how hard you try\u2014and resulting in an instantaneous drop of pressure to zero.<\/p>\n\n\n\n

Solution: Connect the garden hose and turn the faucet to its maximum setting. At this time, do not start the engine or turn on the power under any circumstances. I simply squeezed the water gun\u2019s trigger hard and kept the water flowing continuously for a full two minutes. You will hear the nozzle continuously puffing air until the water flow becomes steady, strong, and free of bubbles; then release your grip and ignite to start the engine.<\/p>\n\n\n\n
