Prepaid Meter Error Codes: Complete Troubleshooting Guide

Is your prepaid meter showing an error code or rejecting your token? This comprehensive guide covers the most common prepaid meter errors in Nigeria and how to fix them — whether you have a MOJEC, Hexing, or MOMAS meter.

Common Prepaid Meter Errors and Fixes

Error: "Reject" or "Token Rejected"

What it means: The meter did not accept the token you entered.

How to fix:

  1. Double-check the token — make sure you entered all 20 digits correctly
  2. Turn off the meter at the mains switch
  3. Wait 30 seconds
  4. Turn it back on
  5. Re-enter the token
  6. If it still fails, you may need to enter a KCT (Key Change Token) first — contact your DISCO or UtilityWallet support

Error: "DLMS" or "DLMS Error"

What it means: Communication error between the meter and the system.

How to fix:

  1. Switch off all appliances connected to the meter
  2. Turn off the meter at the mains
  3. Wait 2 minutes
  4. Turn it back on
  5. Try entering the token again

Error: "SGC" (Standard Transfer Specification)

What it means: The meter needs a tariff update or key change.

How to fix: Contact your DISCO to request a new KCT (Key Change Token). Enter the KCT before entering your electricity token.

Error: "Tamper" or "Tamper Detected"

What it means: The meter has detected potential tampering.

How to fix: This requires a visit from your DISCO's technical team. Contact your DISCO directly to schedule an inspection. Do not attempt to fix this yourself.

Error: "Low Credit" or "Low Balance"

What it means: Your remaining units are running low.

How to fix: Buy more electricity units. Visit UtilityWallet.ng to recharge instantly.

Meter Screen Is Blank

What it means: The meter may have tripped, lost power supply, or have a hardware fault.

How to fix:

  1. Check if the main switch is on
  2. Check if there is power supply to your area
  3. Press any button on the meter to activate the display (some meters have auto-off displays)
  4. If none of these work, report to your DISCO for technical inspection

How to Check Your Prepaid Meter Balance

Different meters have different methods:

  • MOJEC meter — Press 65 then Enter
  • Hexing meter — Press 07 then Enter
  • MOMAS meter — Press the blue button
  • Conlog meter — Press # then 65 then #

The display will show your remaining kWh (kilowatt-hours).

When to Contact Your DISCO

Contact your DISCO directly if:

  • Your meter shows "Tamper" error
  • Your meter screen is completely blank and won't respond
  • You need a KCT (Key Change Token)
  • Your meter is physically damaged
  • You've been charged for a new meter and haven't received it
