Initial Checks for Power Washers
Before diving into complex repairs , start with some basic checks. These initial steps can pinpoint the problem quickly. They apply to both electric and gas-powered models.
- Power Source:
- Electric Power Washer: Check the outlet. Make sure the circuit breaker hasn’t tripped. Test the outlet with another appliance to confirm it has power. Inspect the power cord for any cuts or damage.
- Gas Power Washer: Verify there is enough fuel in the tank. Gas can go bad, especially if it’s been sitting for a long time. Add fresh fuel if needed.
- Water Supply:
- Make sure your water hose is connected properly. Whether you are using a hot water or cold water power washer, the water supply must be turned on fully. A lack of water pressure can prevent the power washer from starting.
- Check for kinks in the hose. A kink will restrict water flow. Ensure the water inlet filter is clean, preventing debris from entering the pump.
- On/Off Switch:
- This might seem obvious, but confirm the power washer’s on/off switch is in the “on” position. Sometimes, it’s just a simple oversight.
- Some power washers have a safety switch; check if that is engaged.
Electric Power Washer Specifics
Electric power washers have their own set of potential problems. These machines rely entirely on a steady electrical current. Problems often stem from power delivery.
- GFCI Tripping:
- Ground Fault Circuit Interrupters (GFCIs) are safety devices. They trip if they detect a fault.
- If your GFCI keeps tripping, the power washer may have an internal electrical issue. Try plugging it into a different GFCI outlet.
- A constantly tripping GFCI indicates a serious electrical problem. This often requires professional repair.
- Motor Overload:
- An electric motor can overheat from extended use. This triggers a thermal overload protector.
- Allow the power washer to cool down completely. It might restart once the motor reaches a safe temperature.
- If it continues to overheat, there might be a blockage or a pump issue.
- Internal Wiring:
- Loose or damaged internal wiring can prevent an electric power washer from starting. This is harder to diagnose without opening the casing.
- Unless you are comfortable with electrical work, it’s best to consult a professional. Tampering with internal wiring can be dangerous.

Gas Power Washer Specifics
Gas power washers rely on a combustion engine. This means a different set of troubleshooting steps compared to electric models. Fuel, air, and spark are key.
- Fuel System Checks:
- Old Fuel: Fuel can degrade over time. Old fuel can clog the carburetor. Drain old fuel and refill with fresh gasoline.
- Fuel Filter: A clogged fuel filter restricts fuel flow. Replace the fuel filter if it looks dirty or shows signs of blockage.
- Carburetor: The carburetor mixes air and fuel. A dirty carburetor can prevent starting. You might need to clean or rebuild it. This can be complex.
- Fuel Shut-Off Valve: Make sure the fuel shut-off valve is in the “open” position. Some models have this feature.
- Spark Plug Issues:
- Dirty Spark Plug: A dirty or fouled spark plug won’t ignite the fuel. Remove the spark plug and inspect it. Clean it with a wire brush.
- Wet Spark Plug: A wet spark plug means too much fuel is entering the cylinder. This can happen from over-choking. Let it dry out.
- No Spark: Test for spark. Connect the spark plug to its wire. Hold it against a metal part of the engine. Pull the starter cord. You should see a blue spark. If not, replace the spark plug.
- Air Filter:
- A dirty air filter restricts airflow to the engine. This can cause poor starting or no starting at all.
- Remove the air filter and clean it. Replace it if it’s heavily soiled or damaged.
- An engine needs a good air-fuel mixture to start properly.
- Engine Oil Level:
- Some gas power washers have a low oil sensor. This prevents the engine from starting if the oil level is too low.
- Check the oil dipstick. Add oil if needed. Use the correct type of oil specified in your power washer’s manual.
- Running an engine without enough oil causes severe damage.
- Choke and Throttle:
- Choke Position: When starting a cold engine, the choke should be in the “full choke” position. This enriches the fuel mixture. Move it to “run” once the engine starts.
- Throttle Position: Ensure the throttle is in the “fast” or “start” position. Some engines require a specific throttle setting to start.
- Recoil Starter:
- If the recoil starter feels stuck or doesn’t pull easily, there might be an internal engine issue. This could be a seized engine.
- Do not force the recoil starter if it’s stuck. This can cause more damage.
- A professional should inspect a seized engine.
If your gas power washer is having trouble starting , contact Serv-Us at (973) 714-1718. We can help you diagnose the issue and suggest whether repairs are feasible. We offer new and used power washers if yours is not fixable.
Pump Problems
The pump is the heart of your power washer. Issues with the pump can prevent it from starting or building pressure.
- Frozen Pump:
- If you stored your power washer in freezing temperatures, water inside the pump might have frozen. This expands and can crack the pump.
- Allow the power washer to thaw completely in a warm area. A cracked pump requires replacement.
- Always winterize your power washer before cold weather.
- Clogged Inlet/Outlet:
- Debris can clog the water inlet filter or the nozzle. This restricts water flow.
- Clean the inlet filter. Use a small wire to clear the nozzle.
- A blocked nozzle can prevent the engine from building pressure.
- Seized Pump:
- Lack of use or improper storage can cause the pump to seize. This means internal components are stuck.
- Try turning the pump manually if possible (check your manual). Some suggest squirting a little oil into the pump inlet.
- A seized pump often requires replacement.

Proper Storage and Maintenance
Preventive measures save you a lot of headaches. Proper storage and regular maintenance are key to a long-lasting power washer.
- Winterization:
- Drain all water from the pump and hoses before freezing temperatures.
- Use pump protector fluid. This prevents freezing and lubricates internal pump parts.
- Follow your power washer’s manual for specific winterization steps.
- Fuel Storage:
- For gas power washers, drain the fuel tank for long-term storage.
- Add fuel stabilizer to the gas if you plan to store it for a few months. This prevents fuel degradation.
- Running the engine until it runs out of fuel also works.
- Regular Cleaning:
- Clean the exterior of your power washer after each use. Remove any dirt or debris.
- Keep the air filter and fuel filter clean.
- Regular cleaning helps identify potential issues early.
