There is an older thread from October 2022 with the very same problem but a software solution that does not work an all such devices. After a lot of searching I found a solution on the Whirlpool forums that finally did work.
Hardware revision V4 seems to be missing a jumper that has to be soldered. User dairyman supplied a picture pointing out the exact location (red box) where the two contacts need to be bridged. With the jumper in place the problem is fixed.
I do not know how to add this information to the device page and so I would be happy if somebody could do that as such problems can be anywhere between a major nuisance and a complete show stopper when dealing with a new device.
