- Tape the existing electrical cable to the floor so that it is not disturbed when the new dishwasher is moved into place.

The installation kit also contains a new water supply valve.
- Disconnect the old supply line from the shut-off valve.
- Route the new supply line through the hole between the sink cabinet and the dishwasher installation location.
- Temporarily secure the new water supply line to the floor with tape to prevent movement when the new dishwasher is pushed into place.
