Briggs & Stratton Briggs & Stratton 3200 PSI 4.5 GPM Gas Pressure Washer MECH-MOTOR-TRIPS Error Fix: Motor Trips Breaker (Electric Models)

Error code MECH-MOTOR-TRIPS on the Briggs & Stratton Briggs & Stratton 3200 PSI 4.5 GPM Gas Pressure Washer means: Motor Trips Breaker (Electric Models). The electric pressure washer trips the home circuit breaker when started, or trips the GFCI on the power cord. Electric pressure washer motors draw high startup current (15-20 amps momentarily). They require a dedicated 15-amp or 20-amp circuit — do not share the circuit with other appliances. Never use an extension cord unless it is 12-gauge or heavier, and less than 25 feet long — voltage drop from a long or thin extension cord prevents the motor from starting and can damage it. If using a GFCI outlet, ensure it is in good condition — worn GFCI devices can trip prematurely. If the breaker trips during operation (not just startup), the motor may have a winding short.
