Wallbox 110: the charger could not read the charging-cable resistor correctly
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
High
Quick answer
110 means the charger could not read the charging-cable resistor correctly in the cited charger family. The deciding observation is whether a known-compatible second cable clears 110 after the original is reseated once. Do not infer a failed part from the code alone.
Safety first
Stop and check this first
- Do not force, twist repeatedly or use a wet, damaged, scorched or deformed plug or cable. Stop charging if the connector cannot be released normally.
Safe checks you can perform
- Capture the exact charger, vehicle and pattern
- Run the one deciding check
- Use recurrence as the stop point
Leave these tasks to a qualified professional

What a technician must be able to justify
A technician is coming
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 110
What they doVerify cable coding/resistance and connector contacts, then compare the charger’s reading circuit with the exact supported cable specification.
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 110 and record the Wallbox 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 force, twist repeatedly or use a wet, damaged, scorched or deformed plug or cable. Stop charging if the connector cannot be released normally.

Run the one deciding check
No special tools
Procedure
Disconnect the cable from the charger, wait for the LED to turn white and insert it fully once. If 110 returns, compare one known-compatible cable already available. Record whether a known-compatible second cable clears 110 after the original is reseated once. Change one condition only.
Do not force, twist repeatedly or use a wet, damaged, scorched or deformed plug or cable. Stop charging if the connector cannot be released normally.

Use recurrence as the stop point
No special tools
Procedure
If only the original cable reproduces 110, the cable path is isolated strongly enough for compatibility inspection—not an automatic purchase. If two compatible cables produce 110, the evidence moves away from one cable and toward the charger socket/reading circuit.
Do not force, twist repeatedly or use a wet, damaged, scorched or deformed plug or cable. Stop charging if the connector cannot be released normally.

What it means
Wallbox’s official documentation defines 110 as the charger could not read the charging-cable resistor correctly. That is the protection or controller state, not a universal component diagnosis. If only the original cable reproduces 110, the cable path is isolated strongly enough for compatibility inspection—not an automatic purchase. If two compatible cables produce 110, the evidence moves away from one cable and toward the charger socket/reading circuit.

Symptoms and causes
Probable causes · in order
- What the manufacturer code establishesConfirmed
Wallbox documents 110 as a state in which the charger could not read the charging-cable resistor correctly. Keep this meaning scoped to the cited charger family and exact light/code pattern.
