Q: When the sterilizer was turned on this morning, it started making very loud sounds. The sound was so loud it made the fan rattle loudly. The temperature actually began to drop and when we attempted to run a cycle, an error message Err-31 came on and the machine was beeping continuously until the machine was unplugged. Please get back to me as soon as convenient. I tried to resolve this over the phone which would be quicker but would not be transferred was only told to refer to the website.

A: Error 31 is a low or no heat condition. Remove the drawer and turn the sterilizer on. Confirm that there is air movement inside the chamber and the main blower should not make any noise. If the main fan is pushing air and NOT making any knocking noises and there is still no heat, the heater element is probably bad and this can be confirmed by measuring ohms or doing a continuity test on it. If the blower is knocking, it would need to be replaced.

As of this date the parts for repair of Original style Cox Sterilizers is limited

If your cox sterilizer unit is stuck at a temperature, for example at 347 degrees, then the solution is to simply unplug it to reset the logic circuitry.

Q: Our sterilizer heated up to approximately 252 degrees this morning, and then shut itself off. It won’t turn on again. I pulled out the documentation for it and found a couple of fuses in the file. Is it possible we just need to replace a fuse? No one saw an error message before it shut down.

A: The problem is most likely from the fuse if there is no error message. On the backside of the machine, use a screw driver to take the fuse out and check its ohm value. It should be near 0 ohm. If the fuse is damaged, its ohm value should either be very big or have no value. You can just replace the fuse. However, if the fuse on the back is not the problem, then factory service is needed. The problem then originates from the fuse on the heating element.

The fan on the back cover should run any time the sterilizer is on, and the same goes for the blower inside the chamber.

Emitting loud noises is a bit vague, so not sure how to address the issue. Please call us to try and narrow down.

The most probable reason for this is usually a bad heater element, but at times it can be caused by a failed main blower or a damaged circuit board. Check to make sure that with the drawer removed and the unit turned on, that there is good air-flow in the chamber.
You can unplug the sterilizer, remove the back and check the ohms on the heater element.

The temperature for the newest model Cox sterilizer may run up to 385f.  You must use bags which were made for Dry Heat Sterilizers.  Those bags would work up to 450f.  The steam or combination steam/dry heat pouches will melt in the Cox units which require dry heat only pouches.

If you want to talk further about this, please call me.

Q – What does the code “PF” mean when it comes up on the temperature screen.
A – It means ’Power Fail Code’.   You need to unplug the sterilizer and plug it back in order to reset.
