Model-specific home chargepoint fault-light observation

A chargepoint light colour has no reliable universal meaning, so identify the exact model before interpreting it. Record the colour, flash pattern, display text, time and charging state exactly as observed. Use only that model's operating manual, and stop using the chargepoint if the indication is unknown, persistent or accompanied by another warning sign.

Key facts and evidence

For UK home chargepoints, as reviewed on 12 August 2026, indicator meanings are model-specific rather than universal. The permitted user action is to record the exact colour, pattern, display text, time and charging state, then compare those observations with the matching operating manual. An unknown or persistent indication, or any accompanying hazard sign, requires support rather than experimentation.

Record a home chargepoint light or display exactly and use only the operating manual for that precise model to interpret it.

Why colour is not enough

Manufacturers define their own indicators, potential errors and required actions. A colour-only interpretation can therefore assign the wrong meaning to the observed state.

A useful support record

Exact model, pattern, text, time and charging state give support a faithful observation while keeping the user away from undocumented fault actions.

What to do next

Keep charging stopped while the exact indication is matched to the correct operating manual or referred to support.

Immediate action: Record the visible indication without changing the equipment state.

  • The exact chargepoint model or matching operating manual cannot be confirmed.
  • The indication is unknown, persists or the manual directs professional support.
  • Heat, odour, unusual sound, smoke, moisture or visible damage is also present.

Checks that stay with this vehicle

  1. Use the handover record or normally visible model label to identify the exact chargepoint model.

    The model identity matches a specific operating manual from the manufacturer.

    Stop if the model identity or matching manual cannot be confirmed.

  2. Record the exact light colour, flash pattern, display text, time and charging state.

    The record preserves the indication exactly rather than assigning a generic colour meaning.

    Stop if heat, odour, unusual sound, smoke, moisture or damage is present.

  3. Compare the recorded indication only with the matching model operating manual.

    The manual gives an exact match and identifies whether manufacturer or electrical support is required.

    Stop if there is no exact match, the indication persists or the manual directs professional support.

Professional hand-off

  • Send manufacturer support or a registered competent electrician the model identity, exact indication, time and charging state.
