What does the Power DN error code mean on your Tuttnauer autoclave?
Once you place your equipment in your autoclave and turn it on, it is important that you allow the cycle to run to completion, without interruption. Depending on the size of the load, the cycle time can vary from 15 to 45 minutes. If something were to happen to the power source of your Tuttnauer autoclave, you will get a Power DN error code, which means that for some reason the power was cut off and the cycle was interrupted.
There is certainly no reason to panic, power can fail for various reasons. Someone tripped over a wire or Mother Nature cut an electrical wire. The Power DN error code simply lets you know that there was an interruption in the cycle and you may need to start the cycle again when power is resumed. Here’s what to expect when you see that error code:
When the power is reconnected, your autoclave will automatically attempt to resume the cycle where it left off.
If the power was cut off while the machine was in the warm-up phase, the warm-up will resume. However, if the power was off long enough, there may not be enough water left in the camera. If that is the case, the cycle will be canceled and you will have to start over.
If the power failure occurred during the sterilization phase of the cycle, the machine will automatically check to make sure that the temperature in the chamber has not dropped more than 4.5ยบ F. If it has, the cycle will be canceled and you will have to start over. new with a new cycle.
Once the power is turned on again, the extraction and drying cycles will automatically resume.
If you have liquids in your autoclave when the power goes out, you will have to start a new cycle. The system will not allow a quick escape after a power outage.
It is important to understand that when your Tuttnauer autoclave displays a Power DN error code, it means the cycle was interrupted. Even if you only have a minute left, it is still not a complete cycle and your equipment may not be properly sterilized. If the power was off for only a short period of time, your machine will automatically complete the cycle. However, if not, due to one of the reasons listed above, you will have to start a new cycle, regardless of how little time was left when the power went out. Otherwise, your tools and equipment will not be sterilized properly.
It is also important to note that the tape on your autoclave may indicate that the proper temperature levels have been reached. However, this does not mean that your equipment has been sterilized. If the cycle was interrupted and does not automatically resume where it left off, you will need to repeat it from the beginning to ensure proper sterilization of your equipment.
