Dishwasher Detergent Dispenser

Repair Instructions:

During the wash cycle, a dishwasher detergent dispenser releases detergent into the tank. Certain dispensers have a rotating cover or latch with an O-ring or seal that can wear out. This wear and tear may cause water to leak between the door panels and onto the floor near the bottom of the door. If you notice any signs of leakage or suspect a problem with the detergent dispenser you will need to replace the dispenser.

How to Replace Dishwasher Detergent Dispenser

  1. Disconnect power at the circuit breaker.Turn off power for safety before servicing.

  2. Locate the dispenser inside the dishwasher tub.This is where detergent is added.

  3. Remove any mounting screws or retaining clips.Look inside dispenser compartment.

  4. Detach wires from dispenser module if applicable.Gently disconnect each wire.

  5. Lift out the old dispenser module straight up once fully disconnected.Carefully remove.

  6. Clean the mounting area where new dispenser will attach.Remove any debris.

  7. Position replacement dispenser module onto mounting surface.Align holes if needed.

  8. Reinstall mounting screws or clips to secure new dispenser.Don't overtighten fasteners.

  9. Reconnect any wires one by one matching positions.Refer to photos if taken earlier.

  10. Run a test cycle with detergent added.Make sure proper dispensing and dissolving occurs.

  11. Check final installation and fit.

Dishwasher Door Gasket

Repair Instructions:

Inspect the gasket for tears, gaps, or cuts. You can test the contact of the door gasket by closing the dishwasher door on a dollar bill all the way around. If the bill doesn't stick, there may be a gap in the gasket. If there are any gaps or leaks, replace the gasket. If the gasket is fine but the dishwasher still leaks, examine the door hinges. Bent hinges can prevent proper door closure, creating a gap between the gasket and the dishwasher. If the hinges are bent, replace them.

How to Replace Dishwasher Door Gasket

  1. Turn off power to dishwasher.Unplug the appliance from the wall outlet to safely work.

  2. Open door and remove outer door panel.Look for mounting clips, screws or tabs holding the outer panel in place. Use a screwdriver to release any clips or screws securing it.

  3. Locate and remove old gasket.The old gasket will be glued into the inner door frame groove. Gently peel it away, going slowly to avoid damaging the door frame surface.

  4. Clean groove thoroughly.Use a rag with soapy water or adhesive remover to wipe away any remaining pieces or adhesive from the groove.Rinse well and dry completely.

  5. Apply adhesive to new gasket.Apply a continuous bead of adhesive provided with the replacement gasket kit along the back edge of the new gasket.

  6. Install new gasket into groove.Carefully press the gasket into place, working out any bubbles by smoothing it down fully into the groove.

  7. Replace outer door panel.Align and snap the outer panel back on securely. Replace any screws if needed.

Dishwasher Tub Seal

Repair Instructions:

If you notice water leaking around the front of the dishwasher, it could be due to a problem with the door gasket. The tub seal of the dishwasher is typically made of soft rubber or vinyl and is placed around the door or tub opening, creating a tight seal to prevent water leakage. Some dishwasher models also have rubber baffles at the bottom corners of the tub opening, which help prevent water from leaking in that area. As vinyl or rubber ages, it can become less flexible or brittle, leading to potential damage or improper sealing.

How to Replace Dishwasher Tub Seal:

  1. Safety Precautions:

    • Before you begin, ensure the dishwasher is disconnected from the power source to guarantee your safety during the replacement process.
  2. Access the Dishwasher Tub Seal:

    • Identify the location of the tub seal, which is typically situated around the opening of the dishwasher tub, forming a water-tight seal.
  3. Gather Necessary Tools and Replacement Parts:

    • Ensure you have the required tools, including a screwdriver, pliers, and a compatible replacement tub seal.
  4. Remove the Dishwasher Access Panel:

    • Depending on your dishwasher model, you may need to remove the lower front access panel to access the tub seal. Use the screwdriver to detach any screws holding the panel in place.
  5. Access the Tub Seal:

    • Once the access panel is removed, you can access the area where the tub seal is located.
  6. Remove the Old Tub Seal:

    • Carefully detach the old tub seal from its mounting point using pliers or your fingers, depending on how it is secured.
  7. Clean the Area:

    • Before installing the new tub seal, make sure the area is clean and free from any debris or residue.
  8. Prepare the New Tub Seal:

    • Unpack the replacement tub seal and inspect it for any defects. Ensure it is clean and free from any packaging materials.
  9. Install the New Tub Seal:

    • Carefully position the new tub seal in the same location as the old one, ensuring it fits snugly and forms a proper water-tight seal.
  10. Reattach the Access Panel:

    • If you removed the access panel, reattach it to the dishwasher using the same screws you removed earlier.
  11. Plug In and Test:

    • Reconnect the dishwasher to the power source and run a test cycle to ensure there are no leaks, and the new tub seal is functioning correctly.
  12. Final Check:

    • Inspect the new tub seal to ensure it is properly installed and forming a watertight barrier, preventing leaks during dishwasher operation.
