Briggs & Stratton Briggs & Stratton 3200 PSI 4.5 GPM Gas Pressure Washer MECH-HOSE-LEAK Error Fix: Hose or Connection Leaking

Error code MECH-HOSE-LEAK on the Briggs & Stratton Briggs & Stratton 3200 PSI 4.5 GPM Gas Pressure Washer means: Hose or Connection Leaking. Water is leaking at the connection points — between the garden hose and pump inlet, between the high-pressure hose and pump outlet, or at the spray wand connection. Check all O-rings at connection points — worn or missing O-rings are the most common cause of connection leaks. Carry spare O-rings as they wear with each connect/disconnect cycle. Verify all quick-connect fittings are fully engaged — pull back the collar, insert fully, and release. Do not cross-thread garden hose connections. A split or punctured high-pressure hose must be replaced — do not repair high-pressure hoses with tape or clamps as they operate at 2000-4000 PSI.
