1980s GE electronic Dishwashers
Most important thing to do if you have one of these that you want to actually use his to replace the motor with the new high-efficiency motor. Otherwise the draw from the old black motor tends to ruin the boards.
If you wanted to keep the original motor and all the inherent noise and heat output, put a relay on it so that you don’t damage the circuitboard.
I have seen many of the GSD 2800 and the similar 25, 2600 models burn up the boards on the motor contacts.
