Carpet cleaner powers on but motor does not run; E2 error appears shortly after start.

Safety first: Unplug the Philips carpet cleaner and allow it to cool for at least 30 minutes if it stopped during use.

• Check for mechanical blockage: Remove the clean and dirty water tanks. Turn the unit over and inspect the brush roll and suction inlet for hair, threads, or debris. Remove any obstructions from the brush roll and side channels.
• Test after cooldown: Once the unit is completely cool and cleaned, plug it back in and try again. If the motor runs briefly then E2 returns, the motor may be drawing excessive current.
• Inspect motor and wiring: With the unit unplugged, open the housing to access the suction motor. Check the motor connectors for signs of overheating or loose terminals. Ensure the motor harness is firmly seated on the main PCB.
• Check motor continuity: Using a multimeter, measure resistance across the motor terminals. An open circuit (infinite resistance) indicates a failed motor or open thermal fuse. A very low resistance combined with burning smell suggests a shorted motor.
• Control board relay: If the motor tests good but never receives voltage (test only if you are trained and using proper isolation), the motor relay on the main PCB may be defective and the board should be replaced.

If you are not experienced with mains-voltage testing, stop after cleaning and visual checks and contact a professional.
