What is an E20-00 trouble code and how can I resolve this?
An E20-00 trouble indicates a Dealer programming memory error. The control panel dealer program has been corrupted. This error could have possibly been caused by an electrical surge. A surge can occur after a power outage when power is restored. A surge can also occur during an electrical storm. If you encounter this issue, download the control panel program again. If not using Quickloader, refer to your manual, default the control panel and re-program. This should correct the trouble condition. Test the control panel thoroughly; to help prevent this condition from reoccurring, ground the control panel to a cold water pipe.
