There are batteries in the WMD (Water Management Device – prepaid water meter) that do run down after a number of years – most people get 8-10 years if the valves are not opened and closed too often (by running out of water) or topped up daily.
Here are some reasons why you could be seeing CLOSE:
- Depleted Credit: The most common reason is that you have run out of water credit.
- Tamper Mode: The WMD may be in tamper mode, which will be shown on the UIU by displaying 0L and/or no water droplet visible on the screen.
- Communication Error: There might be a communication issue between the UIU and the WMD *
- Valve Closed Manually: Check if the ball valve on the meter box is closed.
- Water Interruptions: There may be water interruptions in your area.
- Keypad Not Communicating: Try moving closer to the unit, check the state of battery level. **
* You can try resetting the UIU first by pressing #981# on the keypad, which should display “default”.
THEN Re-pair the UIU: After resetting, you can re-pair the UIU by entering #999# followed by the serial number on your water meter (the same number you use to purchase water with OR engraved near the base), and pressing ### after entry.
** The white keypads have a non user replaceable battery in them and have now been replaced with the BLACK Keypads which have user replaceable batteries – https://stratlec.co.za/shop/prepaid-water-meter-user-interface-unit-uiu-keypad-with-user-replaceable-batteries/
