Another Alde Question

Problem: No power to the Alde system, screen fault, “ Red connection fail”
History: 2018 Classic 30 always plugged in to electric power and used at least every other weekend when not traveling. The Alde system was on for heat and hot water all winter. I drain the tank periodically to renew the air cushion. Three weeks ago, when the weather got warm, I shut off the system entirely, heat and water. This past weekend I turned the system on and got a “Red connection fail” fault.
Alde Manual: Connection failure: There is a connection fault between boiler and panel. To reset, disconnect 12 V from the boiler and reconnect.
Actions: I switched the 12 V disconnect button to off and then on, the fault remained. I searched the internet and Forums, including Much ado about Alde and only found “Overheat red failure”. The YouTube vids showed how to disconnect the wires then reconnect them. I did this with no success, the fault remains.
Questions: Has anyone experienced this problem? How do I reset the system? Which wire is the 12 V the manual is referring to? How can I contact Alde USA?

Truma is super helpful on the phone and not a long wait at all. They could probably walk you through the reset process over the phone and prevent a visit to a dealer. Hopefully it’s something simple and not a main board issue. Just replaced mine, shipping was fast and installation was easy... just cost $200 for the panel.

This has happened to me once or twice. Hitting the battery disconnect switch and waiting a minute reset the issue for me.
