If you’re facing issues with your Simpson pressure washer, you’re not alone. Many users encounter common problems that can be resolved with a bit of troubleshooting. This article will guide you through various techniques to diagnose and fix your pressure washer efficiently.
From minor hiccups like low water pressure to complex mechanical failures, understanding your machine’s quirks can prevent extensive damage and prolong its lifespan. Dive into our straightforward tips and methods to keep your Simpson pressure washer running smoothly.
Check water supply connection
Make sure your water supply connection is secure. Disconnect the hose from the pressure washer and inspect both ends for any damage. Check for kinks or blockages that may restrict the flow of water.
Ensure the water supply is turned on fully. Insufficient water can lead to low pressure or even damage the pump. Verify that your hose diameter matches the specifications in the manual to avoid flow issues.
If the water is still not flowing properly, look at the inlet water filter. Clean out any debris that may have accumulated. Regular checks ensure your pressure washer performs at its best.
Inspect nozzle for clogs
One of the first things to check when your Simpson pressure washer isn’t working properly is the nozzle. A clogged nozzle can significantly affect performance. Disconnect the nozzle and inspect it closely for any debris or dirt.
Use a small wire or a needle to gently clear any obstructions from the nozzle. Take care not to damage it while cleaning. After clearing the clog, reattach the nozzle securely.
Run the pressure washer again to see if the problem is resolved. Cleaning the nozzle regularly can prevent clogs and maintain optimal performance. Make it a habit to inspect the nozzle after each use.
Clean or replace air filter
Keeping the air filter clean is essential for your Simpson pressure washer’s performance. Begin by locating the air filter, which is usually within an air box assembly.
Remove the air filter cover to access the filter. Inspect it for dirt and debris. If it’s visibly dirty, wash it with soapy water and let it dry completely.
If the filter is damaged or too dirty to clean, it’s time to replace it. Replacing the air filter ensures your pressure washer operates smoothly and prolongs the engine’s life. Always refer to your manual for specific instructions.
Verify Unloader Valve Operation
First, disconnect the pressure washer from its power source and water supply. Locate the unloader valve near the pump.
Check the valve for visible signs of damage, such as cracks or leaks. If you see any, the valve may need replacement.
Connect the pressure washer to the water supply, then power it on. Trigger the gun and observe the pressure gauge.
Release the trigger and watch the pressure gauge spike. Adjust the unloader valve handle in quarter-turn increments, then repeat the spray test.
If the pressure doesn’t stabilize within the desired range, the unloader valve might not be functioning properly and could require professional servicing or replacement.
Examine Spark Plug Condition
To examine the spark plug condition on your Simpson pressure washer, start by ensuring the engine is off and has cooled down completely. Locate the spark plug, typically found on the top or side of the engine.
Use a spark plug socket and ratchet to remove the spark plug. Inspect the electrode for any buildup, which you can clean using a wire brush. Check the gap between the electrodes to ensure it’s properly set as per the manufacturer’s specifications.
Look for any signs of wear or damage. If the spark plug shows signs of extensive wear, overheating, or damage, it’s best to replace it with a new one. Proper maintenance of the spark plug ensures effective ignition and smooth operation of your pressure washer.
Ensure Fuel is Fresh and Sufficient
Your Simpson pressure washer relies on fresh fuel to run efficiently. Stale gasoline can cause starting problems or reduce performance. If you’ve got fuel that’s been sitting for over a month, it’s wise to drain it and refill with fresh gasoline.
Always make sure there’s enough fuel in the tank before starting your pressure washer. Check the fuel level and fill up if necessary. Keeping the tank topped up helps prevent unexpected shutdowns during use.
Don’t overlook the importance of proper fuel storage. Use a clean, approved container and store it in a cool, dry place to maintain fuel quality. Regularly inspect your fuel and replace it when needed to avoid engine issues.
Look for Leaks in Hoses and Fittings
When troubleshooting your Simpson pressure washer, the first thing you should do is check for leaks in the hoses and fittings. Even a small leak can cause a significant drop in pressure.
Inspect the entire length of the hose. Look for any visible cracks, bulges, or other signs of wear. If you find any, it’s time to replace the hose.
Next, examine the connections and fittings. Ensure that they’re tight and secure. Use pliers to tighten any loose connections, but be careful not to overtighten and damage the threads.
If you notice water leaking from the pump body, it might require professional repair. In this case, reach out to Simpson’s Customer Service or visit their website to find a service center near you.
Inspect Pump for Wear and Tear
When inspecting your Simpson pressure washer pump, the first step is to remove the pump from the pressure washer. This lets you get a closer look at each part.
Check the pump for obvious signs of damage like cracks or leaks. If you see any damage, you’ll need to replace the affected parts.
Examine the O-rings and seals, as these are common points of failure. If they look worn or damaged, replace them before reassembling the pump. This can often prevent leaks and maintain proper pressure.
Test Pressure Washer Pump Oil Level
To ensure your Simpson pressure washer operates smoothly, it’s important to regularly check the pump oil level. Begin by placing your pressure washer on a level surface. This ensures an accurate oil level reading.
Locate the oil level indicator or dipstick on the pump. Remove the dipstick and wipe it clean. Reinsert it fully, then take it out again to check the oil level.
The oil should be between the “Full” and “Add” marks. If it’s below the “Add” mark, you’ll need to add the recommended oil type until the level reaches the “Full” mark. Always avoid overfilling as it can harm your pump’s performance.
Confirm Power Switch Functionality
First, ensure that the power switch is in the ‘ON’ position. Sometimes, it can be accidentally left in the ‘OFF’ position or get toggled without notice.
Next, check if the switch moves smoothly without resistance. If it’s stuck or feels loose, there may be an internal issue needing professional repair.
Additionally, inspect for any visible signs of damage around the switch, such as cracks or discoloration. Such damage could affect the switch’s performance and may require replacement.
