Dishwasher in kitchen.

Replacing the dishwasher in your kitchen isn’t that difficult a DIY project, though it does require a bit of basic plumbing and wiring. Here’s how to go about it:

Replacing a Dishwasher:

  1. Turn off the power to the dishwasher at the circuit breaker box.
  2. Turn off the water to the dishwasher at the cut-off valve under your sink (if there isn’t a cut-off valve, turn the water off at the water meter).
  3. Disconnect the dishwasher water supply line and the drain line. Drain the hoses into a bucket or pot.
  4. Remove the bottom panel of the dishwasher, and disconnect the wires from the electrical box.
  5. Remove the screws attaching the dishwasher to the cabinet or countertop, and pull the dishwasher out of the opening.
  6. Install a separate electrical outlet box for the new dishwasher if required by building codes.
  7. Position the new dishwasher near the cabinet opening and reconnect the water supply line, drain pipe, and electrical wires.
  8. Fish the water supply line, drain pipe, and electrical wire through the cabinet wall into the adjoining cabinet under the sink, and slide the dishwasher in place.
  9. Use the adjustable feet to level the dishwasher.
  10. Attach the dishwasher to the cabinet or countertop using screws.
  11. Connect the water supply line, drain line, and electrical wires.
  12. Turn the water and power back on, and test the dishwasher to see if it works properly.

  1. Hello,
    I recently purchased a scratch and dent Bosch dishwasher SHE4AM12UC/05 and am trying to install it myself.
    I did take the old dishwasher out myself.
    It seems like the Bosch has more hoses than the instructions say.
    I see the water intake hose and understand that part.
    I understand the electrical part and feet levelors.
    But the drain hose is not easy to interpret [for me].
    Any ideas why I have extra hoses?
    Thanks

  3. HELP! I need to replace my KitchenAid dishwasher. The dishwasher was installed before the tile floor and tile counter tops were put in many years ago. It sets about 2 inches below the tile floor. Cutting the legs off would give us enough clearance, but the dishwasher motor would still be too low to get the dishwasher out. Any suggestions on how to remove my dishwasher without damaging the tile floor and countertop would greatly be appreciated.
    Thank you

  4. Why there is an extra fitting on the pump housing next to the drain hose with an opening is a new frigidaire dishwasher .
