This is cool, I hadn't seen that fix before.
Don't want to change your sale post into a discussion (but maybe it will help the sale!)
Part of me wonders though, whether it will mask the underlying issues that cause the resets in the first place (like dirty pins causing added resistance that can lead to overheating, or flipper diodes needing replacement). Since I have fixed them, I've always thought of the WPC resets as an early warning sign that something in the machine needs servicing. Others may disagree.
