How do I replace a Drain Hose in a Dishwasher?

Follow these steps to fix your issue:

  1. Shut off electrical power and water supply to the dishwasher.

    If you want to completely cut off electrical power to the dishwasher, you can flip the house circuit breaker switch to the Off position. Make sure the control panel can't be turned on if power is disconnected. The dishwasher has a water supply valve. Shut off the water supply to the dishwasher.

  2. Remove the bottom front access panel and toe panel.

    The screws that hold the front access panel in place can be removed with a 1/2-inch nut driver. Remove the access panel and the toe panel and put them away. Refer to your installation manual for more information on removing the toe panel.

  3. Pull out the dishwasher.

    There is a junction box at the front of the dishwasher. The wires need to be disconnected from the junction box. The dishwasher is secured in the cabinet opening with 2 mounting screws. From under the counter, pull the dishwasher out. If you don't have enough slack in the water supply line and the drain hose, you won't be able to pull the dishwasher in front of the counter. If you have enough slack in the electrical supply wiring, you can pull out the dishwasher without connecting the wires.

  4. Disconnect the drain hose from the drain pump.

    If you have to use pliers, reach under the dishwasher and squeeze the wire hose clamp that holds the drain hose to the drain pump. The drain pump has a drain hose on it. To absorb water from the drain hose, place a towel under the drain pump.

  5. Remove the drain hose from the water inlet assembly.

    The plastic nut that secures the water inlet assembly can be removed with a pair of channel lock pliers. The dishwasher tub has a drain hose on the left side. Pull the water inlet assembly out.

  6. Disconnect the drain hose from the drain line to the sink.

    The dishwasher drain hose that goes to the drain pump should be separated from the kitchen sink drain hose. Take the drain hose out of the dishwasher. To remove the drain hose, use pliers.

  7. Connect the new drain hose.

    Attach the dishwasher drain hose to the drain pump, carefully working the hose onto the drain pump outlet and onto the connection to make sure it doesn't leak. Attach it with the wire hose clamps. The original drain hose was routed through the water inlet brackets. Attach your newly installed drain hose to the portion of the drain hose that goes to the kitchen sink drain. Make sure the connection is safe. The drain hose needs to fit tightly on the drain pump. It usually requires a lot of force to get the drain hose onto the drain pump outlet.

  8. Reinstall the water inlet bracket.

    You can screw the plastic nut onto the plastic nut from the inside of the tub if you position the water inlet brackets on the side of the tub. Attach the plastic nut to the water inlet. Carefully tighten the nut and you will be able to seal the inlet. The plastic nut or the tub can be cracked if you overtighten the nut.

  9. Reinstall the dishwasher.

    The dishwasher needs to be pushed under the counter. Remove the junction box cover and connect the wires to the junction box. The access panel and toe panel should be replaced. Attach the dishwasher to the counter mounting brackets and tighten the screws. The access panel should be positioned in front of the toe panel on the dishwasher. The screws need to be inserted and tightened firmly. Refer to the dishwasher installation guide for more information.

  10. Restore the water supply and electrical power.

    To get the water supply back to the dishwasher, open the water supply valve. The circuit breaker needs to be reset.

Time required: 30 minutes.

You would need the following tools: 1/4-inch nut driver, channel lock pliers, slot screwdriver, standard pliers, towel, work gloves.
