Started the pump, everything was fine, but temperature on the unit kept climbing over the next 2-3 days (the next day it said my water was at 88F, it was actually at ~77F), until it eventually reached 112F (actual temperature is more like 80F), and then started displaying the code "ot", according to the manual "Water temperature is higher than 45°C (113°F) within the unit". Could it be a faulty temperature probe?
