if this happens say within a minute of starting (assuming machine has filled) program now at the point when the HEATER should be starting to heat the cold water , I suspect a heater element/possible relay problem this is causing the program knob to spin to indicate a fault.find the heater element and remove the wires now test across the heater for continuity using a DMM set on BUZZER.
It MUST buzz to indicate a good element
no buzz change the heater element
