How to Install Dishwasher Tub Insulation 154641601 in a Kenmore Dishwasher
Quick answer: Disconnect power, water and drain, slide the dishwasher out of its cabinet, peel the old blanket off the top and sides of the tub, drape 154641601 over the tub with the cutouts aligned to the hoses and wiring, tuck the edges behind the base frame, then reinstall and test.
The tub insulation 154641601 is the fiber blanket that wraps the outside top and both sides of the stainless or plastic tub on Kenmore and Frigidaire dishwashers such as the FDB949GFS1, FGID2466QW2A, FFBD2409LS0A, GLD2555NDB0 and Kenmore 58714131102. It cuts wash and drain noise reaching the kitchen and helps the tub hold heat during the wash and dry phases. A blanket that has torn, sagged off the tub, become soaked from a leak or was left out after an earlier repair makes the machine noticeably louder and can leave the dry cycle weaker.
This is not a difficult repair, but it requires pulling the dishwasher fully out of its cabinet because the blanket wraps the sides of the tub where nothing can be reached in place. Plan for the water and drain connections to come off and take note of how the old blanket was folded around the hoses and wiring harness before you remove it. This guide explains how to get the machine out, fit the new blanket so it stays put and confirm the noise reduction once everything is back.

- Unplug the dishwasher or switch off the breaker and confirm the control panel is dead before disconnecting the junction box wiring.
- Close the water supply valve and relieve pressure before loosening the supply fitting.
- Wear gloves and a dust mask; the insulation fibers irritate skin and lungs, and the tub flanges are sharp.
- Keep the door closed and latched while sliding the machine out so it does not tip forward.
Tools and Parts You Need
- Phillips screwdriver
- Quarter-inch nut driver
- Adjustable wrench for the water supply fitting
- Slip-joint pliers for the drain hose clamp
- Towels and a shallow pan
- Work gloves and a dust mask
- Flashlight
Step-by-Step Installation
- Disconnect power, water and drain Unplug or trip the breaker and close the supply valve. Remove the kick plate, open the junction box cover, disconnect the wiring, then unscrew the supply line from the inlet valve and release the drain hose clamp under the sink.
- Free the dishwasher from the cabinet Remove the mounting screws at the countertop or side brackets and lower the leveling legs. Pull the dishwasher forward a few inches, feed the supply line and drain hose through the cabinet opening, then slide the machine out onto a towel.
- Remove the old blanket Peel the old insulation off the top and sides of the tub, noting where it was tucked behind the base frame and how it was cut around the vent, wiring and hoses. Bag the old blanket to keep fibers out of the kitchen.
- Inspect the tub and hoses With the tub exposed, look for water stains, corrosion and hose leaks that may have ruined the old blanket. Fix any leak now, since a soaked new blanket will not insulate.
- Position the new blanket Unfold 154641601 and drape it over the top of the tub with the center panel on top and the two side panels hanging down. Line up the factory cutouts with the vent, float switch wiring and side hoses.
- Tuck and secure the edges Push the bottom edge of each side panel behind the base frame or under the side brackets so it cannot slide up. Fold the front edge back so it does not interfere with the door hinges or the latch.
- Reinstall the dishwasher Slide the machine back into the cabinet while feeding the supply line and drain hose through, raise the leveling legs until the top is level and the door swings freely, then replace the mounting screws.
- Reconnect and test Reconnect the supply line, drain hose and junction box wiring, replace the kick plate, restore water and power and run a cycle. Listen for a quieter wash and check for any drips under the machine.
Fit Checks Before You Call the Job Done
- The blanket covers the top and both sides of the tub with no bare stainless or plastic showing.
- All cutouts line up with the vent, wiring and hoses, and nothing is pinched.
- The edges are tucked behind the base frame and do not shift when the machine is slid.
- The door opens and closes without catching on the blanket.
- The wash cycle is noticeably quieter and the dry cycle finishes normally.
Common Mistakes to Avoid
Skipping the leak inspection If a hose leak soaked the old blanket, the new one will fail the same way. Fix the source before insulating.
Leaving the blanket loose at the bottom A blanket that is not tucked slides up the tub when the machine is pushed in and bunches at the front. Anchor the edges before reinstalling.
Pinching wiring under the blanket The float switch and heater wires run along the tub. Route them through the cutouts, not under a fold.
Forgetting to relevel the dishwasher Legs lowered for removal must be raised again or the door will sag and the tub will not drain fully.
Troubleshooting After Installation
Machine still sounds loud after the new blanket The side panels are not against the tub. Pull the machine out and check that the blanket is flat on the sides and not bunched at the front.
Door rubs when opening The front edge of the blanket is folded into the hinge path. Fold it back along the tub flange.
Leak under the machine after reinstall The supply fitting or drain clamp is loose. Tighten both and recheck with a full fill.
Dishwasher does not fill The float switch wiring was disturbed under the blanket. Reconnect it and confirm the float moves freely.
Care Tips After the Repair
- Check under the kick plate yearly for moisture that could soak the blanket.
- Do not pull the dishwasher out without lowering the legs, which tears the blanket on the cabinet edge.
- Keep the drain hose loop high under the sink so backflow does not wet the base area.

It is listed for Kenmore and Frigidaire dishwashers including FDB949GFS1, FGID2466QW2A, FFBD2409LS0A, GLD2555NDB0, PLD2850RDC3 and 58714131102. Check the model label on the door edge.
Can I fit the blanket without removing the dishwasher?
No. The blanket wraps the sides of the tub, which cannot be reached in the cabinet. The machine has to come out.
Does the blanket affect drying?
Yes. It helps the tub hold heat after the final rinse, so dishes dry better and the machine runs more quietly.
Is the blanket fiberglass?
It is a fiber insulation blanket, so wear gloves and a mask and bag the old one rather than shaking it out in the kitchen.
