Trouble Shooting

Keypad gives ‘FAILED’ message
The keypad is unable to communicate with your meter. Make sure there is no major obstruction between your meter and your keypad, for example a vehicle parked next to you meter. During installation, the best position for your keypad was selected for the best radio communication. If this problem persists, contact your Call Centre.

Meter not dispensing water On your keypad check if the Water Tap icon is displayed. If displayed, then you have credit and the meter is open. Check if your neighbour has water, as it is possible that the whole area is without water. If the Water Tap icon is not displayed, you meter may be locked or you do not have credit on your meter.

No Free Basic Water (FBW)
Confirm if you are eligible to receive FBW, if it is daily or monthly and from what time it is available. For daily FBW the keypad should display ‘FREE’ every morning automatically. Monthly FBW starts on the first day of each month. The keypad displays ‘FREE’ until your FBW is finished. If you did not receive it, contact your Call Centre. They will be able to determine if FBW is activated on your meter, or when and how much FBW you already used. You may also not receive your FBW automatically, but have to collect your FBW tokens from your nearest vendor.

Water gets finished quickly
Check for leaks on your property or maybe somebody else is using your water. Lock your meter when you are away from home, and check for any leaking pipes, taps and toilets. The ‘Leak’ icon should never be visible on your keypad.

No Credit on my meter
When the ‘No Cred’ message is displayed, you have no credit on your meter and it is closed. Purchase more credit.

Possible water Leak
If there is a water leak, a water drop as well as a ‘LEAK’ message is displayed on your keypad. Press #11# to see how much water is lost per hour due to this leak. It is important to fix this leak, as it will finish your credit very quickly. Once the leak is repaired, the message disappears the next day.

Keypad is not switching on
Replace the batteries in your keypad. You can purchase any AA size Alkaline (Penlight) battery at your local store, and fit them. If it still does not work, report to your nearest Call Centre.

There is an error message on my keypad
Write down the error code and report to your nearest Call Centre.

My token does not work
Make sure the Prepaid Number on the receipt is the same as on your meter. You cannot enter a token from another meter. See Loading Credit for possible messages returned by your meter. If the meter returns an error code when you enter your token, contact the Call Centre and give them the error code.
