Bosch dishwashers typically use a vertical pump design. This design allows for better water drainage and efficient operation. However, keep in mind that specific models and designs may vary over time, so it's always a good idea to check the user manual or contact the manufacturer directly to get the most up-to-date information on their dishwasher pump design.
Regarding your Kenmore 630 series dishwasher, without knowing the exact model number, it is challenging to provide precise information about its pump design. Kenmore dishwashers, being produced by various manufacturers over the years, can have different pump configurations. If you're interested in finding out the specific pump design of your Kenmore dishwasher, I recommend looking up the model number on the appliance itself or referring to the user manual.
