Display shows E15; unit detects ground fault or leakage current and will not run

Safety: Unplug immediately. Do not bypass ground fault protection. Risk of electric shock.

• Dry the unit: If the Husqvarna carpet cleaner was recently exposed to heavy moisture, allow it to dry in a warm, ventilated area for 24–48 hours.
• Inspect for leaks: Check hoses, tanks, and seals for signs of leakage onto electrical components. Repair or replace leaking parts before further use.
• Check wiring insulation: Look for nicks or cuts in wires, especially near moving parts and tank areas. Replace damaged harnesses.
• Professional testing: Because ground faults are safety-critical, have a qualified technician perform insulation resistance tests and repair or replace the main PCB if the detection circuit is faulty.
