Carpet cleaner displays E5 and shuts down shortly after starting; may trip household breaker.

Safety first: Unplug immediately if the breaker trips or you smell burning. Do not repeatedly reset a tripping breaker.

• Inspect the power cord: Check the entire length of the cord for cuts, crushed sections, or exposed copper. Replace the cord set if any damage is found.
• Check for moisture ingress: Ensure no water has leaked into the motor compartment or electrical connections. If the unit has been exposed to water internally, allow it to dry completely for at least 24 hours in a warm, dry place.
• Visual inspection inside: With the unit unplugged, remove the housing panels to access the suction motor, pump, and PCB. Look for burnt components, melted insulation, or scorch marks.
• Isolate components (advanced): Disconnect the suction motor and try powering the unit (if safe and per service documentation). If E5 disappears, the motor is likely shorted. Repeat with the pump disconnected to isolate the fault.
• Replace faulty component: Replace the shorted motor, pump, or PCB as identified. Ensure all wiring is routed correctly and secured away from moving parts and hot surfaces.
