What Is a Westinghouse Pressure Washer?

A Westinghouse pressure washer is a high-pressure mechanical sprayer designed to remove loose material, dirt, grime, mold, and even old paint from hard surfaces. These machines work by using an electric motor or a gas-powered engine to drive a pump that pressurizes water from a garden hose or a dedicated water supply. The pressurized water is then forced through a specialized nozzle at extremely high velocity, creating a powerful cleaning jet.

Westinghouse offers a range of pressure washers suitable for homeowners, DIY enthusiasts, and light commercial users. Their lineup includes compact electric units perfect for cars and small patios, as well as rugged gas-powered machines capable of handling heavy-duty jobs like stripping concrete, cleaning large fences, and preparing surfaces for painting.

Understanding what your machine is capable of helps you use it correctly and avoid misuse that could damage the unit or the surface you are cleaning. Every Westinghouse pressure washer comes with a rated pressure measured in pounds per square inch (PSI) and a flow rate measured in gallons per minute (GPM). These two numbers together determine the cleaning power, known as cleaning units, of the machine.

Before You Start: Safety Precautions

Safety should always come first when operating any pressure washer. Before attempting to start your Westinghouse unit, take the following precautions seriously. Pressure washers can cause serious injury if used carelessly, and proper preparation prevents accidents.

• Wear safety glasses or goggles. Debris and water spray can cause eye injuries at high pressure.
• Wear closed-toe shoes and long pants. This protects your feet and legs from flying objects and high-pressure water.
• Never point the nozzle at people or animals. Even at low pressure, the spray can cause skin injuries.
• Read the owner’s manual. Every model has specific instructions and warnings. Familiarize yourself with them before operating.
• Check for leaks. Inspect all hoses, fittings, and connections before turning on the water supply.
• Ensure proper grounding. Electric models must be plugged into a grounded outlet. Never use an extension cord unless it is rated for the amperage required.
• Keep children and pets away. The noise and spray can be dangerous for unsupervised individuals.
• Never bypass the safety lock or trigger lock. These mechanisms prevent accidental spraying.

Taking these precautions every time you use your pressure washer creates a safe working environment and protects both you and your equipment.

Understanding Your Westinghouse Pressure Washer Model

Westinghouse manufactures several different pressure washer models, and the exact startup procedure can vary depending on whether you own a gas or electric unit. Knowing your model type is essential before you begin the starting process.

Most Westinghouse home-use pressure washers fall into two categories: electric and gas-powered. Electric models are typically lighter, quieter, and easier to maintain. They are ideal for tasks like washing cars, cleaning decks, and light driveway cleaning. Gas models offer significantly more power and portability since they do not require an electrical outlet. They are better suited for heavy-duty cleaning, large surface areas, and use in remote locations without access to electricity.

Check the label on your machine or the original packaging to confirm your model type. The model number is usually printed on a metal plate or sticker located on the frame or near the engine. Having this information handy is useful if you ever need to order replacement parts or look up model-specific instructions.

Step-by-Step Starting Guide

Regardless of whether your Westinghouse pressure washer is gas or electric, there are several universal pre-start steps you should follow every time. This checklist ensures everything is in proper working order before you attempt to start the engine or motor.

1. Check the oil level. Most Westinghouse pressure washers have a small oil reservoir that needs to be filled before first use or after extended storage. Remove the oil fill cap, check the level using the dipstick or sight glass, and add the recommended oil if needed.
2. Check the fuel level. For gas models, ensure the fuel tank is at least half full. Use fresh gasoline and avoid old fuel that may have degraded. If the unit has been sitting for more than 30 days, drain old fuel and refill with fresh gas.
3. Connect the water hose. Attach a standard garden hose to the water inlet on the pressure washer. Ensure the connection is tight and free of leaks.
4. Attach the spray gun and wand. Connect the high-pressure hose to the pump outlet and attach the spray gun. Make sure all fittings are secure.
5. Choose the correct nozzle. Select the appropriate spray tip for your task. A wide-angle nozzle is best for general cleaning, while a narrow tip provides more pressure for stubborn grime.
6. Turn on the water supply. Open the faucet or spigot fully and let water flow through the system until the hose is primed. This removes air pockets that can damage the pump.
7. Squeeze the trigger. With the water flowing, squeeze the trigger on the spray gun briefly to release any remaining air from the system.
8. Start the engine or motor. Follow the specific starting procedure for your model type, as detailed in the sections below.

Following these steps in order prevents most starting problems and protects the pump from damage caused by dry running or air pockets.

How to Start a Westinghouse Pressure Washer: Electric Models

Starting an electric Westinghouse pressure washer is generally straightforward, but a few details matter. Electric units rely on an electric motor to drive the pump, so the electrical connection must be correct and secure.

1. Plug the unit into a grounded outlet. Use a standard three-prong outlet. Never use an adapter that bypasses the ground pin. If you must use an extension cord, choose a heavy-duty cord rated for at least 12 AWG and no longer than 50 feet.
2. Turn on the water supply. Open the spigot and allow water to flow through the machine until the system is fully primed.
3. Set the pressure regulator to low. If your model has an adjustable pressure knob, set it to the lowest setting before starting. This reduces the strain on the motor during startup.
4. Press the power switch or button. Most electric models have a simple on/off switch. Flip it to the on position.
5. Pull the trigger. Squeeze the trigger on the spray gun to activate the motor and begin water flow. The motor should start within one or two seconds.
6. Adjust the pressure. Once the motor is running, slowly increase the pressure regulator to your desired setting. Always adjust pressure while the unit is running and water is flowing.

If the motor does not start, unplug the unit immediately and check the circuit breaker, the outlet, and the power switch. Electric models are sensitive to voltage drops, so avoid running them on circuits shared with other heavy appliances.

How to Start a Westinghouse Pressure Washer: Gas Models

Gas-powered Westinghouse pressure washers offer more power and mobility. Starting them involves a few more steps than electric models, but the process becomes second nature with practice. (See Also:What Soap Pressure Washer)

1. Check the fuel and oil. Confirm the gas tank has sufficient fuel and the engine oil is at the correct level. This is the most common reason a gas pressure washer will not start after storage.
2. Move the choke lever to the closed position. The choke restricts airflow to create a richer fuel mixture for cold starting. If the engine is warm, you may not need the choke, but starting with it closed is always safe.
3. Turn the fuel valve on. Make sure the valve between the fuel tank and the carburetor is open. A closed fuel valve is a surprisingly common reason for failure to start.
4. Set the throttle to slow or idle. Locate the throttle lever and set it to the low-speed position. This prevents the engine from racing when it starts.
5. Pull the starter cord. Grip the starter handle and pull firmly and steadily. You may need several pulls to get the engine firing. Do not pull the cord more than five or six times in rapid succession; allow the engine to rest briefly between attempts.
6. Allow the engine to warm up. Once the engine starts, let it run for one to two minutes at idle. Then slowly move the throttle to the running speed.
7. Open the choke gradually. After the engine has warmed up, move the choke lever to the open position. This restores normal airflow and prevents the engine from running rich, which wastes fuel and can foul the spark plug.
8. Squeeze the trigger to begin spraying. With the engine running at the proper speed, squeeze the trigger on the spray gun and begin your cleaning task.

Some Westinghouse gas models feature a recoil starter, while newer units may have an electric start. The process is similar in both cases, but electric start models require a fully charged battery. Always keep the battery charged and the connections clean.

Common Starting Problems and Troubleshooting

Even with proper preparation, you may occasionally encounter problems when trying to start your Westinghouse pressure washer. Here are the most common issues and their practical solutions.

The engine does not start at all. This is usually caused by stale fuel, a closed fuel valve, or a disconnected spark plug wire. Check the fuel supply, ensure the valve is open, and inspect the spark plug for corrosion or wear. Clean or replace the spark plug if necessary.

The engine starts but stalls immediately. This often indicates a choke that is stuck in the closed position or a clogged fuel filter. Open the choke fully and check the fuel filter for debris. Replace the filter if it appears dirty.

The engine sputters or runs rough. A rough-running engine may have air in the fuel line, a dirty carburetor, or low oil. Bleed the fuel line to remove air bubbles, clean the carburetor, and top off the oil.

The electric motor does not start. Check the power outlet, the circuit breaker, and the power switch. Ensure the water supply is turned on, as many electric models have a flow switch that prevents the motor from running without water flowing.

The unit starts but produces low pressure. This can be caused by a worn nozzle, a clogged filter, or air leaking into the system. Check all connections, clean or replace the nozzle, and inspect the inlet filter for debris.

Addressing these issues promptly prevents further damage and keeps your pressure washer ready for use whenever you need it.

Tips and Best Practices for Long-Term Use

Owning a Westinghouse pressure washer is a significant investment, and proper care ensures it delivers reliable performance for many years. Follow these best practices to get the most from your equipment.

• Use fresh fuel. Gasoline begins to degrade after about 30 days. If you do not use the unit frequently, add a fuel stabilizer to the tank before storage.
• Change the oil regularly. Most models require an oil change after the first 20 hours of use and then every 100 hours or at least once per season. Fresh oil keeps the engine running smoothly and extends its lifespan.
• Clean or replace the air filter. A dirty air filter restricts airflow and reduces engine performance. Inspect the filter before each use and clean or replace it as needed.
• Inspect hoses and fittings. Regularly check all hoses, connections, and seals for cracks, leaks, or wear. Replace damaged components immediately to prevent pressure loss or water damage.
• Store properly. When not in use, store the pressure washer in a dry, sheltered area. Drain the fuel and oil if storing for extended periods, and cover the unit to protect it from dust and moisture.
• Run the unit periodically. Even if you do not have a cleaning job, run the pressure washer for a few minutes every month. This keeps the pump seals lubricated and prevents internal components from seizing.
• Use the correct detergent. When washing vehicles or surfaces that require soap, use only detergents rated for pressure washers. Household cleaners can damage the pump and void your warranty.
• Never run the unit without water. Running the pump dry causes rapid overheating and can destroy the pump within seconds. Always ensure water is flowing before starting the engine or motor.

These habits take only a few minutes but save significant time, money, and frustration over the life of your pressure washer.

Gas vs Electric: Comparison Table

Choosing between a gas and an electric Westinghouse pressure washer depends on your specific cleaning needs. The table below highlights the key differences to help you make an informed decision.

Both types are excellent choices depending on your needs. If you want to know how to start a Westinghouse pressure washer of either type, the procedures outlined earlier in this guide apply directly.

Common Mistakes to Avoid When Starting Your Pressure Washer

Even experienced users sometimes make mistakes during the starting process. Avoiding these common errors helps protect your equipment and ensures reliable starts every time.

Skipping the oil check. Many people forget to check the oil before starting, especially after storage. Running an engine with low or no oil causes severe internal damage. Always check the oil level first. (See Also:How To Prime Pressure Washer Pump)

Using old or contaminated fuel. Stale fuel is the number one reason pressure washers fail to start. If your unit has been sitting for more than a month, drain the old fuel and refill with fresh gasoline.

Forgetting to prime the system. Starting the pump without water flowing causes cavitation, which can damage the pump internals. Always turn on the water supply and allow the system to prime fully before starting the engine.

Leaving the choke closed too long. On gas models, running with the choke closed for an extended period floods the engine with fuel and can cause stalling or carbon buildup. Open the choke as soon as the engine warms up.

Over-tightening fittings. While it is important to secure all connections, over-tightening can crack fittings or damage threads. Hand-tighten plus a quarter turn is usually sufficient.

Ignoring the pressure rating. Using a pressure washer with too high a PSI for a delicate surface can cause irreversible damage. Always match your pressure washer and nozzle to the task at hand.

Neglecting winterization. If you live in a cold climate, failing to winterize your pressure washer before freezing temperatures can burst the pump and hoses. Drain all water and add antifreeze according to the manufacturer’s instructions.

Avoiding these mistakes keeps your Westinghouse pressure washer in top condition and prevents costly repairs.
