  1. 1

    Turn off the power to the dishwasher circuit at the breaker panel or fuse box.

  2. 2

    Open the panel underneath your old dishwasher and disconnect the power connections.

  3. 3

    Reach underneath the kitchen sink and turn off the hot water supply. Then disconnect the hot water feed and drain tube coming from the dishwasher.

  4. 4

    Loosen the mounting screws and pull out the old dishwasher.

  5. 5

    Slide the new Bosch dishwasher up to the edge of the cabinet.

  6. 6

    Apply Teflon tape to the threads on the hot water feed and tighten the new water supply line to the connection.

  7. 7

    Feed the supply line and electrical wiring through the chase at the back of the cabinet into the opening for the dishwasher. It may help to tape the two down to the floor with duct tape to keep them in place.

  8. 8

    Slide the dishwasher halfway into the opening and feed the drain line back through the chase into the under-sink cabinet. Connect the drain line to the disposal or drain and tighten the clamp with a flathead screwdriver.

  9. 9

    Slide the dishwasher in the rest of the way. Remove the front, bottom panel of the dishwasher (if it isn't already removed). Reach underneath the dishwasher and pull the electrical and supply lines forward.

  10. 10

    Apply Teflon tape to the water supply connection, and connect the supply line feed to the connection with an open-end wrench.

  11. 11

    Connect the power line to the wires in the electrical junction box (white to white, black to black, copper to green wire for ground) with wire nuts. Close the cover of the box and secure by tightening the screws.

  12. 12

    Attach the mounting brackets to the cabinet using the screws included with the dishwasher.

  13. 13

    Turn on the hot water supply and check for leaks on both ends of the feed. If there are none, reattach the underside panel to the front of the dishwasher.

  14. 14

    Turn on the dishwasher's electrical circuit at the breaker panel or fuse box and test the dishwasher. Make sure the drain line doesn't leak at the connection under the sink.

Tips and warnings

  • Before disconnecting the old dishwasher, make sure the power is turned off at the breaker panel or fuse box to avoid the risk of an electrical shock.
