How to Fix / Troubleshooting

Safety first: Disconnect mains power. This fault involves high-voltage electronics; only qualified persons should perform board-level repairs.

  • 1. Visual inspection: Remove the top cover and inspect the power electronics module for burn marks or damaged components.
  • 2. Check motor harness: Inspect the cable from the control module to the motor for chafing or shorts to chassis.
  • 3. Test motor windings: With a multimeter, measure resistance between motor terminals and to earth. Shorted windings require motor replacement.
  • 4. Replace faulty components: Replace the V-ZUG drive motor if windings are shorted. If the motor is good, replace the power electronics module.
  • 5. Technician involvement: Due to the complexity and safety risks, E51 repairs should generally be carried out by an authorized V-ZUG technician.
