Charger displays E110 and will not start; often appears immediately at power-up.

Safety first: If the unit previously emitted smoke, odor, or loud popping sounds, leave it off and contact a professional immediately.

• Extended power reset: Turn OFF the breaker for 10 minutes, then turn it back ON. Some self-test faults clear after a full discharge.
• Check environment: Ensure the charger is not exposed to dripping water, direct rain (if indoor-rated), or extreme temperatures outside Bosch specifications.
• Inspect for external damage: Look for cracks in the housing, impact marks, or signs of water ingress. If present, do not use the charger.
• Do not bypass safety: There is no safe way for a homeowner to bypass internal self-tests. If E110 persists, internal components such as the relay, current sensor, or power supply must be diagnosed and replaced by a qualified technician.
