Kia home charger shows E09 and refuses to charge; may occur after a lightning storm or power surge.

Safety first: After a surge event, internal components may be compromised. Do not continue using the charger if it smells burnt or shows visible damage.

• 1. Inspect for visible damage: Look at the charger housing for burn marks, cracks, or melted areas. If present, shut off power and do not use the unit.
• 2. Check other devices: If other electronics in the home were affected, a surge likely damaged the charger’s internal surge protection.
• 3. Internal inspection (technician): With power off and cover removed, a technician can inspect the MOVs and input filter on the power board for cracking, charring, or bulging. Any damaged components require board replacement.
• 4. Install external surge protection: Ask an electrician to install a whole-house or dedicated surge protector for the EV charger circuit to prevent future damage.
• 5. Replace power board: If the MOV or input filter is damaged, the safest repair is to replace the entire power board with a Kia-specified module rather than attempting component-level repair.
