Doorbell not ringing

My RVD (2?) of about two years of age used to work fine, ringing itself, a chime and the old doorbell. However, due to many motion alerts I decided to add a wedge. Unfortunately, this did not help much and the hardwired bell did not ring anymore either. Just this week the RVD died and I found out that the hardwired bell was not powering the RVD. I removed the wedge and successfully tested the doorbell by shorting out the two wires. After reinstalling the RVD, Device Health shows the Hardwired Status BUT the doorbell does not ring. This is very annoying as we have a number of repeaters driven by the old doorbell, due to my wife’s hearing problem.
Any ideas what is wrong, what other trouble shooting I can do?
