Bosch SHE53T52UC/01 Installation Instructions Manual page 17

If your sink is to the right side of where you are installing the dishwasher,
you will need to reposition the hoses behind the dishwasher before installing.
To do so, unhook the strap that the hoses are running through on the
back of the dishwasher base and position them per your requirements.
If your sink is to the left side, leave the hoses as they came and skip to
step 16.
