Miele system reports F14 ground fault or insulation error; disposal is locked out from operation.

Critical safety warning: Do not attempt to operate the disposal until the ground fault is resolved. Turn off the breaker and leave it off. Risk of electric shock is present.

• Inspect for moisture: Check for leaks above the disposal that may be dripping onto wiring or the motor housing. Correct any plumbing leaks first.
• Check cord and wiring: Look for cuts, crushed sections, or burn marks on the power cord and internal wiring. Do not touch bare conductors.
• Drying: If minor moisture is present, allow the area to dry completely for 24 hours with the power off, then have a qualified technician perform insulation resistance tests.
• Professional service: Ground faults typically require motor or wiring replacement and should be handled by a licensed technician or electrician.
