Pressure washers are powerful cleaning tools that can make quick work of outdoor cleaning tasks, from washing decks and driveways to cleaning vehicles and outdoor furniture. However, like any mechanical device, pressure washers can encounter issues that affect their performance. Whether you have an electric or gas-powered pressure washer, understanding how to troubleshoot common problems can help you maintain your machine and keep it running efficiently. This guide provides simple, practical tips to help you identify and resolve typical pressure washer issues, ensuring your equipment works effectively when you need it most.
Why is My Pressure Washer Not Working Properly?
Common Problems with Pressure Washers
- Pressure Washer Won’t Start: For electric models, check if it’s properly plugged in and the circuit isn’t overloaded. For gas-powered units, ensure there’s fresh fuel in the tank and the fuel valve is open. Check if the spark plug is connected and in good condition. Verify that the on/off switch is in the correct position. If the issue persists, there may be a problem with the motor or pump requiring professional repair.
- Low or No Pressure: This could be due to a clogged nozzle or inlet filter. Clean these components thoroughly. Check for kinks or leaks in the hose. Ensure the water supply is adequate and the faucet is fully open. Verify that the unloader valve is properly adjusted. If the problem continues, the pump seals may be worn and need replacement.
- Pressure Washer Pulsing or Surging: Air in the system can cause pulsing. Bleed the air out by running the machine without the spray wand until water flows steadily. Check for a partially clogged nozzle or a worn out pump. Ensure all connections are tight and there are no leaks in the system.
