I have one of this units,it turns on but when i press start counting it give me an error "err pu ", I assume it means error in the pump.
The pump makes no noise at any time,and recives no voltage from the pc board,by powering the pump with a external power supply the pump makes noise ,I assume is ok.
The unit works with 6 v dc and it has an internal led acid battery wich is bad ,replacing this battery whith 6 v externalyy makes no change still got the error message.
Thanks
