How to Spot a Faulty Prepaid Meter Before It Fails

Aug 05, 2025

Prepaid meters are a lifesaver for controlling electricity expenses, but a faulty meter can cause unexpected power cuts and financial losses. Learning how to detect early signs of a malfunction can save you time, money, and hassle.

Signs Your Prepaid Meter May Be Faulty

  • Unusual Error Codes: If your meter frequently displays error messages like “30,” “70,” or “Error,” it may be signalling an internal fault.
  • Token Rejection: A healthy meter should accept valid tokens easily. If your token fails repeatedly, your meter may need attention.
  • Power Fluctuation Despite Adequate Units: If your lights flicker or go off even when you have enough units, the meter’s relay might be faulty.
  • Display Screen Issues: A blank, frozen, or flickering screen is a red flag.
  • Burn Marks or Strange Odours: Physical signs of damage indicate serious internal issues.

What to Do If You Notice These Signs

  • Contact your electricity distribution company (DISCO) immediately.
  • Report the issue with your meter serial number and error code.
  • Avoid tampering with the meter yourself.

Conclusion

Regularly checking your meter and understanding these warning signs will help you avoid unexpected disconnections and costly repairs.
