5 RED BLINKS
Tesla 5 RED BLINKS: power-sharing communication failed and charging power is reduced
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
5 RED BLINKS means power-sharing communication failed and charging power is reduced in the cited charger family. The deciding observation is whether all grouped Wall Connectors are online and re-link successfully during the commissioning process. Do not infer a failed part from the code alone.
Safety first
Stop and check this first
- Do not change breaker ratings, current limits fixed by the installer, protective devices or Wi-Fi security to clear a connectivity code.
Safe checks you can perform
- Capture the exact charger, vehicle and pattern
- Run the one deciding check
- Use recurrence as the stop point

What a technician must be able to justify

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Measured handoff for 5 RED BLINKS
What they doVerify every unit’s role, firmware, Wi-Fi reachability and power-sharing topology, then recommission the group without altering protective-device design.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

Capture the exact charger, vehicle and pattern
No special tools
Procedure
Photograph 5 RED BLINKS and record the Tesla model, part/serial number, vehicle model, cable used, charge stage and approximate time. Do not clear the event before those facts are saved.
Do not change breaker ratings, current limits fixed by the installer, protective devices or Wi-Fi security to clear a connectivity code.

Run the one deciding check
No special tools
Procedure
Check Wi-Fi signal and follow Tesla’s commissioning process to re-link the existing Wall Connectors for power-sharing; do not change breaker ratings. Record whether all grouped Wall Connectors are online and re-link successfully during the commissioning process. Change one condition only.
Do not change breaker ratings, current limits fixed by the installer, protective devices or Wi-Fi security to clear a connectivity code.

Use recurrence as the stop point
No special tools
Procedure
If re-linking restores normal sharing, the group communication state—not available electrical capacity—was the observed boundary. If five blinks remain, do not increase charge current or bypass power-sharing; group topology and commissioning evidence are required.

What it means
Tesla’s official documentation defines 5 RED BLINKS as power-sharing communication failed and charging power is reduced. That is the protection or controller state, not a universal component diagnosis. If re-linking restores normal sharing, the group communication state—not available electrical capacity—was the observed boundary. If five blinks remain, do not increase charge current or bypass power-sharing; group topology and commissioning evidence are required.
