An Overview of the Tub Insulation Shield

The tub insulation shield or insulation blanket is usually made of a material like felt, foam, or fiberglass. The dishwasher insulation blanket helps reduce noise and vibrations while the dishwasher runs, and it gives your cabinets some protection from high temperature and water damage

Over time, the insulation shield can become warped, get small tears or cracks, or completely dislodge from the tub frame. Replacing this part helps to reduce noise and restores insulation.

You’ll need to purchase the manufacturer’s OEM part to properly replace the sound shield. You can take the model number to AppliancePartsPros.com to locate the correct part. Only takes a few tools and you can have your dishwasher running as good as new again.

Replacing the dishwasher tub insulation blanket isn’t difficult, but having the right tools and supplies makes the job much easier. Here’s what you’ll need:

• Phillips head screwdriver – For removing the dishwasher from under the counter. A power drill with a Phillips bit also works well.
• 5/8 inch wrench – To disconnect and reconnect the water supply line.
• 5/16 inch nut driver – For loosening the drain hose clamp.
• Adjustable wrench – Helpful for catching any stripped or stubborn screws.
• Towels – To absorb water spills when disconnecting hoses.
• Gloves – Protect your hands from sharp edges.
• Bucket – For catching water from the hoses.

How to Replace the Dishwasher Insulation Shield

Replacing the tub insulation shield involves disconnecting the dishwasher, swapping out the part, and reinstalling the appliance. Follow these steps:

Turn Off the Power and Water Supply

Before disassembling anything, you need to shut off power and water to the dishwasher.

1. Unplug the dishwasher from the electrical outlet. This prevents accidental electrocution.
2. Turn off the hot water supply under the sink. There’s usually a shut-off valve below the dishwasher’s water line.
3. Place towels beneath the appliance to absorb water spills during the repair. Also, have your bucket ready.

Disconnect Water and Drain Lines

With the power and water off, you can safely disconnect the supply lines.

1. Disconnect the water supply line from the hot water valve using a 5/8-inch wrench. Unscrew the plastic supply line.
2. Disconnect the drain hose from the sink drain or garbage disposal. Loosen the metal clamp with a 5/16-inch nut driver.
3. Catch any water that drains out of your bucket. Keep rags nearby to sop up spills.
4. Inspect the old hoses and gaskets. If cracked or worn, replace them now.

Remove Dishwasher from Cabinets

With the lines disconnected, you can now pull out the dishwasher.

1. Open the dishwasher door and prop it open.
2. Use a Phillips screwdriver to remove the screws along the underside of the countertop. These screws keep the unit snug inside the cabinet.
3. Lift up on the door frame and pull the dishwasher forward several inches. You may need to wiggle it loose.
4. Grasp the sides of the dishwasher and continue sliding it out of the cabinet compartment. Take care not to scratch your cabinets or flooring.
5. Lay the dishwasher on its back so you can access the bottom tub area.

Remove the Old Tub Insulation Shield

With the dishwasher pulled out, you can now detach the old insulation shield.

1. Locate the shield along the bottom of the tub. It will be a large plastic panel, likely discolored from water minerals.
2. Look for plastic hooks or clips that secure the shield to the tub frame.
3. Unclip the shield from the tub on both sides to detach it. This may require firmly tugging it loose.
4. Maneuver the old shield to remove it completely from the dishwasher. Verify no mounting clips broke off.

Install the Replacement Insulation Shield

It’s easy to mount the new shield with the dishwasher exposed.

1. Position the new insulation shield over the tub, lining up any mounting holes and clips. Make sure the textured insulation side faces up into the tub.
2. Press firmly so the shield clips securely onto the tub frame. Go around the perimeter and make sure it sits flush.
3. Check that no wires or hoses are pinched underneath the shield. Make any adjustments needed.
4. Verify a snug fit all around. Run your fingers around the border, pressing down to make sure of proper seating.

Reinstall the Dishwasher

With the new insulation shield installed, it’s time to reverse the removal steps.

1. Slide the dishwasher back into place slowly. Don’t pinch or crush the hoses.
2. Secure the screws underneath the counter to hold the dishwasher snugly in place.
3. Reconnect the drain hose to the sink plumbing and tighten the metal clamp.
4. Reconnect the water supply line to the hot water valve and tighten it firmly.
5. Open the water valve and check for any leaks. Tighten if needed.
6. Plug in the power cord. The dishwasher is now ready for testing.
7. Run an empty wash cycle and verify proper operation and no leaks.
