EV charging-point fault diagnosis — EV charging-point installer

Explain what happens when charging is attempted, including displayed messages, when the problem began and whether it affects more than one vehicle. Do not open the unit or share account passwords; report visible damage or a safety concern so the provider can prioritise appropriate professional assessment.

Service scope

Investigation of a charging failure, intermittent session or equipment warning to distinguish charger, vehicle, supply, communications and account-related causes. The service begins with diagnosis; a failed charging session alone does not identify a replaceable part or justify bypassing a safety function.

What is normally included

  • Review of charging symptoms
  • Equipment and interface diagnosis
  • Repair or escalation recommendation

What is not included

  • Bypassing charger protection or access controls
  • Guaranteed repair without diagnosis

Typical tasks

  • Gather fault and session information
  • Review vehicle and charger compatibility
  • Check relevant equipment interfaces
  • Identify repair or operator dependencies
  • Document the findings and next steps

What to include in your brief

  • Charger and vehicle models
  • Displayed error or app message
  • When the fault occurs
  • Recent installation or account changes
  • Visible damage or environmental exposure

Choosing the right professional

Choose a provider who can separate equipment faults from connectivity or vehicle issues. Ask whether the first fee covers diagnosis only and how manufacturer, network operator or software-provider involvement will be handled if the cause is outside the installer's scope.

Important considerations

  • Continued use of visibly damaged equipment can be unsafe
  • Repeated unsuccessful sessions can have several unrelated causes
