Pressure Washer Lost Pressure Mid-Job

You were halfway through blasting the patio when the jet dropped to a dribble. Rather than guess, this walks you through a proper fault tree: kinked inlet hose, blocked filter or nozzle, air in the pump, worn seals, a stuck unloader valve, thermal cut-out. Tell it your machine type, water source and motor behaviour and it narrows the cause down.

My pressure washer lost pressure while I was using it. It started fine but the jet dropped to almost nothing after {TIME_BEFORE_LOSS}. The machine is {MACHINE_TYPE} powered and I'm using it with {WATER_SOURCE}. The motor {MOTOR_STATUS}. Walk me through a fault tree covering: kinked or restricted inlet hose, blocked inlet filter or nozzle, air in the pump, worn pump seals, unloader valve stuck open, and thermal cut-out tripping due to overheating. For each branch tell me the quick field check I can do without tools, whether running it briefly without the lance helps diagnose it, and which fixes require a spare part versus just a clean.
