The cause of this problem is easy to identify, if you check that the Litres taken were recorded or not.
- If Litres are NOT recorded by the SmartFill GEN2 unit…
- The SmartFill GEN2 unit is most likely not receiving pulses from the flow meter.
- If Litres ARE recorded by the SmartFill GEN2 unit.
- The SmartFill GEN2 unit thinks that the nozzle has been hung up. Check wiring / micros switches etc.
The wiring to the pump / valve may be faulty / poor connections. Check all wiring.
