did u try resetting?
if it still does not work, then can try master resetting:
to do the Master reset, just follow below simple step, but need 2 person:
1st hold mode (pump blinks white)
after that hold mode and press set button together (pump blinks yellow/white)
last step ask someone pull out the power cord (without release the hold mode & set button) then put it back in
and it should be back to normal
