Old washer was 15+ years old.  Do not expect to pop the old one out and pop in the new one.  The Bosch is sealed on the bottom. All lines had to be rerouted  Took a few hours but was worth it.  This washer does an excellent job and is solidly made. It is very quiet.  Standing right next to it you can hardly hear anything.  Rack design is nice and easy to configure.  Excellent choice.
