Prepaid electricity users in Kenya rely on a token-based meter system where power is loaded using a Customer Interface Unit (CIU). This small keypad device allows you to enter 20-digit tokens purchased via M-Pesa or other platforms.
While generally reliable, CIUs and token meters can occasionally display errors ranging from connection failures to rejected tokens. These issues can interrupt your power supply, delay recharges, or cause unnecessary frustration especially during urgent moments.
Some problems are easy to fix with basic troubleshooting, while others like tamper or bypass alerts require a professional assessment by KPLC technicians. Below is a list of common CIU and token meter errors, what they mean, and how to deal with them.
1. Blank Screen on CIU
What it means: The CIU display is completely unresponsive.
Fixes:
- Check if there’s electricity in the house. Ensure the main switch is on.
- Make sure the CIU is securely plugged into a working wall socket.
- Replace old batteries with fresh, heavy-duty alkaline batteries.
- Try loading the token from your neighbour’s house if you share the same power line. Plug your CIU into their socket and enter the token.
If none of these work, report the issue via *977#, the MyPower App, or call 97771.
2. “CON FAIL”, “Connection Fail” or “Fail“
What it means: The CIU cannot communicate with the meter.
Fixes:
- Plug the CIU directly into a wall socket (avoid extension cords).
- Use only quality alkaline batteries.
- Try a neighbour’s socket if you’re on the same KPLC line.
- If the error persists, contact KPLC via *977#, the MyPower App, or 97771.
3. PLC Error (Power Line Communication Error)
What it means: Communication between the CIU and the meter is failing.
Fixes:
- Connect the CIU directly to a wall outlet—no extensions or adaptors.
- Ensure all plug connections are tight.
- Keep electronic devices (TVs, microwaves, routers) away from the CIU while loading tokens, as they can cause interference.
4. Meter Fails to Connect When Loading Tokens
What it means: Tokens don’t register on the meter or no response is received.
Fixes:
- Replace the batteries with fresh alkaline ones.
- Plug into a wall socket directly.
- Check for a blinking red light on the meter box.
- Ensure the circuit breaker or MCB is switched ON.
5. BYPASS Error
What it means: The meter has detected a possible electricity bypass.
Important: Do not attempt to fix this yourself.
What to do:
- Report the issue immediately through *977#, the MyPower App, or call 97771.
- A technician will be dispatched to inspect and resolve the issue.
6. Tamper Error
What it means: Unauthorized access or meter interference has been detected.
Important: This is considered a serious security issue.
What to do:
- Report the error right away via *977#, MyPower App, or 97771.
- Leave the meter untouched until a technician arrives.
7. Loose or Broken Glass on Postpaid Meter
What it means: Physical damage that could affect readings or pose a danger.
What to do:
- Do not attempt to fix or open the meter.
- Report the issue immediately using *977# or the MyPower App (under “Faulty Meter”).
Final Tips
- Always confirm your meter number before buying tokens.
- Use official KPLC channels such as:
- USSD: *977#
- M-Pesa Paybill: 888880
- MyPower app
- Keep token receipts or SMS until the units have successfully loaded.
- During meter upgrades (like TID rollover), follow the instructions sent by KPLC.
