I Have a Steris 333 in the field that is throwing a fault 12 followed by a fault 7 upon canceling the cycle. i put a brand new sump pump in the machine and checked all the cold water flow valves. the only thing i haven't done is calibrated the RTD again. would replacing the RTD probes circumvent having to recalibrate the machine? if not what's the best way to go about recalibration.
