Don’t let engine problems slow you down. Read on to discover how to keep your pressure washer running smoothly.


Resolving Engine Problems in Pressure Washers

Encountering problems with your pressure washer’s engine can be a frustrating experience. Issues with the carburetor, such as it being gummed up with old fuel, can lead to engine instability or even stop it from running altogether.

– Using Carburetor Cleaner for Engine Maintenance

In my experience, a simple and effective solution is to use a carburetor cleaner. This product is designed to remove build-up from the carburetor, which may inhibit its function and impact the overall performance of the engine.

• Addressing Water Pressure Issues

A common cause behind lack of water pressure, or a complete absence of water, may be attributed to a clogged wand, hose, or inlet filter. These components play a crucial role in the operation of your pressure washer, and an obstruction can greatly affect its efficacy.

– Importance of Regular Cleaning or Replacement

Cleaning these elements regularly or replacing them when necessary can solve this issue. In my experience, I have found that people often overlook these simple steps causing their equipment’s performance to suffer.

• Remedying Water Leakage from the Pump

Occasionally, you may notice water leakage from the pump. This could be due to not purging the pump of compressed air before use or a defective thermal release valve.

– Pump Purging and Valve Replacement

For the former, ensure to always purge the pump before operation. As for the latter, changing a defective thermal release valve with a new one can help resolve the issue.

• Identifying and Solving Wand Leaks

Another common issue found in pressure washers is leakage from the wand. Cracks in the wand assembly or damaged rubber O-rings can cause this.

– Replacing the Wand or O-rings

My advice is to replace the entire wand or the O-rings. Over time, these parts may degrade, so regular inspections and replacements can prevent unforeseen leaks.

• Diagnosing Strange Noises and Lack of Water Flow

Hearing strange noises coming from the pump accompanied by no water flow, may indicate pump damage. This often occurs when the pressure washer is stored improperly during winter.

Troubleshooting a Pressure Washer That Won’t Start

We all know the frustration that comes with a pressure washer that won’t start. Whether you’re armed with a gas-powered or an electric machine, a number of issues could be to blame. Before resigning to purchase a new unit, it’s well worth your time to troubleshoot the problem yourself.

• Electric Pressure Washer Troubleshooting

For those using electric pressure washers, begin by investigating the power source. Try plugging the power cord into various outlets.

If it works in one but not another, the issue may be as simple as a faulty outlet. In such instances, you would need to reach out to an electrician to replace the malfunctioning outlet.

If none of the outlets yield success, you might be dealing with a circuitry problem. Look over your electrical panel for any tripped breakers and try resetting them. If that still doesn’t solve the problem, test the outlet’s amperage.

If it falls short of the necessary amperage, you might need to call an electrician to execute panel upgrades or consider purchasing a pressure washer that requires less power.

• Gas-Powered Pressure Washer Troubleshooting

For gas-powered pressure washers, stale fuel could be the problem. Fuel sitting in the washer for six months or more may become contaminated and forfeit its ability to ignite. Recommended action includes draining and cleaning the fuel tank, then refilling it with fresh gasoline.

If this doesn’t rectify the situation, a clogged carburetor or air filter might be the cause. Remove and clean the air filter. Flush the carburetor with a suitable cleaner to eliminate any potential dirt and grime. Should you still face issues after these steps, replacement of the carburetor may be in order.

• Ignition and Spark Plug Trouble

A faulty spark plug or ignition coil could prevent not just pressure washers but most gas-powered devices from starting. If your spark plug appears grimy, fractured, or defective, it’s time for a replacement. Regular spark plug replacements can contribute to the lifespan of your machine.

If there’s no spark on testing the plug, consider replacing the ignition coil. It’s a relatively simple DIY task comprising the removal of the engine cover, followed by the disconnect and removal of the old coil, and the installation of the new one.

For a comprehensive guide on replacing spark plugs and coils, University of Florida offers a useful resource.

• Broken Flywheel Key

If your pressure washer suddenly stops, a broken flywheel key might be the culprit. This small but key element links the crankshaft to the flywheel and is vulnerable to wear and tear. Repairing or replacing a flywheel key is an intricate task best left to a local engine repair shop.

• Pressure and Pump Priming Issues

Excessive water pressure or an unprimed pump could also hinder a pressure washer from starting. To resolve this, discharge any built-up pressure by safely aiming the spray gun and pulling the trigger. For a step-wise guide on the proper priming of the pump and air removal, consult the owner’s manual.

• Hire a Professional

If you have exhausted troubleshooting options and your pressure washer retains its stubbornness, it may be time to hire a professional power washing company.

It might cost between $100 and $650, but considering the time and energy saved, it could well be worth the price. Such companies possess the expertise and high-grade equipment to get the job done right the first time.

Hopefully, this guide aids you in diagnosing and fixing the common issues causing your pressure washer to refuse to start. Happy troubleshooting!
