Ain a pressure washer that's giving you lot problem? Here are six common pressure washer repair problems and how to fix them.
Portable pressure washers are fantastic tools, every bit anyone who owns one will tell y'all. Used properly, a practiced pressure washer can drastically reduce the work and fourth dimension involved in washing decks, cars, siding, farm equipment and more.
Gas-powered washers achieve this with an internal combustion engine that powers a pump, creating highly pressurized water that shoots out of a handheld wand attached to the tool by a hose.
Like all machines, pressure washers sometimes break downwards. These malfunctions take several forms, but in full general, they autumn into two categories: engine issues and pump or wand issues. If you own a pressure washer or are thinking almost purchasing one, keep reading to acquire the most common ways these machines fail, and how to ready and maintain them.
Note: The engine-related issues below merely apply to gas-powered pressure washers. All other issues apply to gas and electric.
Engine Won't Run
If the engine won't run after sitting for a long fourth dimension and you know it'south sparking and has enough oil, there's an splendid chance the carburetor is gummed up with erstwhile fuel. Endeavor opening the carburetor drain plug and letting a picayune old fuel dribble out.
If it nonetheless won't start after buttoning things support, and yous've checked oil, choke, etc., chances are you've got a partial blockage in a carburetor passages. Clearing it involves removing and disassembling the carburetor, and then cleaning it with some carburetor cleaner. Don't effort this solitary if you lot're not confident taking apart and reassembling pocket-sized, important parts.
Trivial Or No Water Pressure
If your pressure washer starts and runs fine, but there'due south no pressure or no water coming from the pump, information technology could be a clogged wand, hose or inlet filter.
Begin isolating the problem past hooking a water hose to the washer'south inlet and turning it on. If h2o flows out the outlet, you know water is cycling through. If non, chances are your inlet filter is clogged. Remove and clean information technology, and you should be good to go.
Assuming water is flowing through the pump properly, start the engine, claw up the hose and wand and come across if it works. If non, you have a collapsed or kinked hose or a chock-full wand. Both problems can virtually likely be fixed quickly without professional help.
Water Leaking From Pump
Compressed air must be purged from the pressure level washer pump before use. Pump the handle before running the engine until water flows from the wand. If this isn't done, the unpurged air can damage bank check valves. On some pressure washers y'all tin supervene upon these individually; on others you need an entire pump replacement.
A defective thermal release valve tin also cause leaks from the pump. This valve lets heated, pressurized h2o exit the pump if the washer is left running for too long without the trigger being squeezed. If the thermal release valve lets water leak constantly, information technology'south lacking and needs replacement.
H2o Leaking From Wand
The lesser end of the wand where information technology attaches to the hose is another common spot for leaks. Leaks at that place not but cause pressure to drop, they leave your arm and sleeve soaking wet, likewise.
Undo the screws holding the wand assembly together, making sure to place them somewhere safety. Carefully examine the inner workings of the assembly nether a brilliant light. If yous spot any cracks, yous'll demand to replace the unabridged wand.
If not, check the land of all rubber O-rings within the wand assembly. If whatsoever of them take cracked or become brittle, that's probably the crusade of your leak. Supervene upon them with identical rings (aforementioned size and thickness) equally explained in your owner's manual.
Foreign Noises From Pump and No Water Flowing
If y'all fire upwards your pressure washer and it runs fine, just there's no h2o flowing and you hear strange noises from the pump, you may accept made a disquisitional and common error terminal season.
In cold wintertime climates your pressure washer needs to exist completely drained of water, and ideally filled with antifreeze, before winter storage. Forget to do this, and you lot'll about certainly leave h2o sitting in your automobile'due south pump. Come wintertime, that water will freeze, expand and critically harm the pump's inner workings.
If this happens, your only option is buying a replacement pump. You can find a video online to guide y'all through the replacement installation, or call a professional person.
Soap Not Dispensing From Reservoir
Some college end force per unit area washers come with a built-in reservoir for special pressure washer liquid soap. The idea is that mixing soap with the pressurized h2o y'all're spraying will help clean things better and faster. My ain pressure washer has this feature, and I can attest that it makes a big difference when you lot've got lots of caked-on dirt to deal with.
Problem is, often the soap doesn't flow properly from the reservoir even when it's filled to the acme. Nine times out of 10, the reason is simple: As well much back pressure level in the pump prevents the soap from existence sucked into the nozzle.
Nearly pressure washers can't draw the thick liquid soap up from the reservoir if you have whatsoever nozzle on the wand other than the weakest, least-pressurizing ane that comes with your machine. No nozzle at all works even better. More aggressive nozzles reduce overall flow rate a lot, and your washer needs sufficient flow charge per unit of h2o to draw up the soap.
So if you've got a lather-enabled pressure washer that won't draw up the soap upwards properly, endeavour removing the nozzle.
