In replacing the float that senses water level on a Hobart AM 14 dishwasher, I see that the whole assembly is free to rotate after the c-clip is reinstalled. Past experience is that sometimes this plastic float will be found upside-down, on top of the probe which houses the reed switch & thermistor temperature sensor. What's to keep the float from rotating like this? Nothing appears to be broken or missing on the assembly from what I can see. THANKS!!!.......Lee
