How to Troubleshoot and Fix: Simpson Pressure Washer Trigger Not Working

Your Simpson pressure washer is a powerful tool that can make quick work of cleaning your home, car, or yard. But when the trigger doesn’t work, it can be a major inconvenience. Fortunately, there are a few simple troubleshooting steps you can take to fix the problem.

Step 1: Check the trigger

The first thing you should do is check the trigger to make sure it’s not stuck. If the trigger is stuck, you can try to free it by applying a little bit of oil or lubricant. If that doesn’t work, you may need to replace the trigger.

Step 2: Check the hose

The next thing you should check is the hose. Make sure it’s not kinked or damaged. If the hose is kinked, you can try to straighten it out. If the hose is damaged, you will need to replace it.

Step 3: Check the pump

If the trigger and hose are not the problem, then the next thing you should check is the pump. The pump is responsible for generating the pressure that powers the sprayer. If the pump is not working properly, it can cause the trigger to not work.

To check the pump, you will need to open the access panel on the side of the pressure washer. Once you have opened the access panel, you can look at the pump to see if there are any obvious signs of damage. If you see any damage, you will need to replace the pump.

If you don’t see any damage to the pump, you can try to start the pump by hand. To do this, you will need to turn on the pressure washer and then hold the trigger down. If the pump starts, then the problem is not with the pump. If the pump does not start, then you will need to replace the pump.

Step 4: Check the electrical components

If the trigger, hose, and pump are not the problem, then the next thing you should check is the electrical components. The electrical components include the switch, the solenoid, and the wiring.

To check the electrical components, you will need to use a multimeter. A multimeter is a tool that can measure voltage, current, and resistance.

To use a multimeter, you will need to connect the red probe to the positive terminal of the battery and the black probe to the negative terminal of the battery. Once you have connected the multimeter, you can turn on the pressure washer and then check the voltage at the switch. The voltage should be between 12 and 14 volts.

If the voltage is not between 12 and 14 volts, then the problem is with the switch. You will need to replace the switch.

To check the solenoid, you will need to disconnect the wire from the solenoid. Once you have disconnected the wire, you can turn on the pressure washer and then check the voltage at the solenoid. The voltage should be between 12 and 14 volts.

If the voltage is not between 12 and 14 volts, then the problem is with the solenoid. You will need to replace the solenoid.

To check the wiring, you will need to visually inspect the wiring for any damage. If you see any damage, you will need to repair or replace the damaged wiring.

Conclusion

By following these troubleshooting steps, you can usually fix a Simpson pressure washer trigger that is not working. If you are unable to fix the problem yourself, you can always take your pressure washer to a qualified repair shop.
