What to do if my Briggs & Stratton POWERflow+ TECHNOLOGY Pressure Washer won't start when I squeeze the trigger?

If your Briggs & Stratton Pressure Washer fails to start when you squeeze the spray gun trigger, there are several possible causes: 1. Ensure the water supply is turned on. 2. Make sure the unit is switched on by pressing the master ON/OFF switch to the ON (I) position. 3. Verify that you are using a garden hose no longer than 50 ft. (15.24 m). 4. Check the fuse box for a blown fuse and replace it if necessary, or reset the circuit breaker. Do not use a fuse or circuit breaker with a higher rating than specified. Try disconnecting other electrical appliances, turning off lights in the circuit, or operating the pressure washer on its own dedicated circuit. Running the pressure washer in any POWERflow+ nozzle setting for 5 minutes may also help; motor break-in may be necessary.
