My Prepaid Meter Is Not Working — What's Wrong?

What Is a Prepaid Meter Problem Problem?

Prepaid electricity meters are standard across most of South Africa, operated by local municipalities for most urban areas and by Eskom in peri-urban and rural areas. When your prepaid meter stops working correctly, it can feel like an emergency — but many problems have straightforward fixes that don't require an electrician.

Common prepaid meter problems include running out of credit, token entry errors, a frozen or blank display, and genuine meter faults. The first step is always to determine which category your problem falls into, as the resolution differs: credit and token issues are handled by the municipality or your token vendor, while meter hardware faults require a technician.

Load shedding can also temporarily affect prepaid meters — some older meter models lose their display during or immediately after a load shedding event, which can appear as a meter fault but resolves on its own.

Common Symptoms & Warning Signs

• Display is blank or shows "0.00" units remaining
• Token (voucher number) is rejected when entered — "INVALID TOKEN" or similar error
• Power cuts out suddenly and the meter shows zero credit
• Meter display is frozen or unresponsive to button presses
• Error code displayed on the meter screen
• Token accepted but units don't appear on the balance
• Meter shows credit but there is no power in the house

What Causes a Prepaid Meter Problem Issue?

• Zero credit: The prepaid balance has been depleted — the most common cause of loss of power
• Invalid token: The 20-digit token number was entered incorrectly, or a token from a different meter type was entered
• Meter tamper detection: Some meters lock out after detecting what they interpret as interference or tampering
• Communication fault: The meter has lost communication with the municipality's network (for smart meters)
• Hardware failure: The meter's internal circuit board or display has failed and requires replacement
• Load shedding display glitch: Power interruptions can temporarily freeze older meter displays

Your local municipality or Eskom accepts meter fault reports and will repair or replace a faulty meter at no charge to the homeowner. Hardware faults are the utility's responsibility.

How Urgent Is This?

Credit depletion and token entry errors are not urgent — they can be resolved by purchasing credit or contacting your municipality's prepaid helpline. These are not electrical faults and do not require an electrician.

A meter that shows credit but provides no power, or a meter that is visibly physically damaged, is higher urgency. This can indicate a fault between the meter and your DB board, which does require an electrician to investigate. A damaged or tampered meter should be reported to your municipality or Eskom immediately.

DIY vs Professional Repair

Homeowners can safely check the credit balance, try re-entering the token carefully (including all 20 digits in the correct sequence), purchase additional credit, and contact their municipality's prepaid helpline if the problem persists. You can also try power-cycling the meter display by pressing the menu button.

Do not attempt to open, bypass, or tamper with a prepaid meter under any circumstances. This is illegal under the Municipal Systems Act and the Electricity Act, and meters are fitted with tamper detection. If the meter itself is faulty, report it to your municipality or Eskom, who will send a qualified technician at no charge. If the fault is in the wiring between the meter and your DB board, that requires a licensed private electrician.

What Professionals Actually Do

If a private electrician is called, they'll first verify that the meter is showing available credit and that the problem is in the supply side of the installation rather than the meter itself. They'll test voltage at the meter output terminals and trace supply through to the main isolator and DB board.

Faults in the wiring between the meter and the DB board — which are the homeowner's responsibility in most cases — will be located using a cable tracer and repaired. The electrician will also check the main earth connection and any isolators or switches between the meter and board.

Property Damage Risks

A prepaid meter fault that results in the property running without adequate metering can attract significant penalties from your municipality if it's deemed to involve supply tampering, even if accidental. Unmetered consumption can also result in large estimated bills when the meter is eventually repaired.

A fault between the meter and DB board — such as a loose connection or damaged cable in that section — carries the same risks as any other loose electrical connection: overheating, arcing, and potential fire damage to the meter box, adjacent walls, and internal wiring.
