Fix heritage shower

The loud popping noise that you're hearing when you open and shut the door of your Whirlpool dishwasher (model # WDT780SAEM1) is most likely caused by the door gasket. The door gasket is the rubber seal that runs around the door, creating a tight seal when the door is closed.
Here are a few things you can try to fix the issue:

1. Check the gasket for damage: Inspect the door gasket for any tears, cracks, or other damage. If you find any damage, you will need to replace the gasket.
2. Clean the gasket: Over time, debris and food particles can accumulate on the gasket, causing it to become stiff and not seal properly. Clean the gasket with a mild detergent and warm water, and then dry it thoroughly.
3. Check the door alignment: Make sure that the door is properly aligned and not hitting the gasket when you open and shut it. If the door is not aligned properly, you will need to adjust it.
4. Lubricate the hinge: If the door gasket is in good condition and properly aligned, the problem may be with the hinge. Try lubricating the hinge with a silicone-based lubricant, as this can help to reduce friction and noise.
5. Contact Whirlpool: If you have tried all of the above steps and are still unable to fix the issue, contact Whirlpool customer service for further assistance. They will be able to provide you with additional troubleshooting steps or advice, or they may need to send a technician to repair or replace the dishwasher.

It's important to note that if the popping noise you're hearing is accompanied by other symptoms, such as leaks, then it may be related to a different problem, and you should contact Whirlpool customer service or a professional service technician for further diagnosis and repair.

You just need a new door gasket and it is a cost effective repair if it still works okay for about $20.

slides out right or left side

Usually the bottom of most framed doors has a chanel which contain door sweep or hollow gasket,all you have to do is pull it and slide the new one in the same place.
Please note that some times the end of the chanel is crimped to prevent the gasket to move in and out of the track.
I hope this will help.

sterling is an inexpensive kohler product,....go to a plumbing supply store with your #s and they'll be able to get what you need.

it's just a door gasket,you might still find it a appliance repair place.

Step 1 Remove the front access panel (see step 1, "Tightening the fittings"). This will give you access to the dishwasher's adjustable feet.

Step 2 Open the door completely and remove the bottom dish rack.

Step 3 Unscrew the dishwasher from the kitchen countertop so the dishwasher can move freely as you adjust the feet.

Step 4 Check to see if the dishwasher is level side to side. Place a small level inside the dishwasher so it's sitting on the bottom pan and facing parallel to the front lip of the dishwasher. If the dishwasher is not level, use adjustable pliers to turn one of the dishwasher's front feet up or down until you hit level.

Step 5 Check to see if the dishwasher is level front to back. Turn the level perpendicular to the door, and place it on one of the bottom ledges that run along the side of the cabinet. Check the level again. If the dishwasher isn't level, use your adjustable pliers to turn the back feet up or down until you hit level.

Step 6 Reattach the dishwasher to the countertop and reinstall the front access panel.
Fixing a leaking door

Step 1 Inspect the door gasket. As it ages, the gasket can crack or become hard, preventing it from sealing completely.

Step 2 If the gasket appears solid, adjust the door latch so the door seals tightly. Loosen the screw that holds the door latch to the cabinet. Push the latch in slightly and retighten the screw. Test the door and readjust the latch if necessary.

Step 3 Replace the gasket if water continues to leak after you've tightened the latch. Most gaskets are held by compression in a groove on the door or on the dishwasher cabinet.

Step 4 Pull the old gasket out of its groove, using adjustable pliers (see illustration). Take the gasket to an appliance store to get a replacement.

Step 5 Soak the new gasket in warm water to soften it, then press it into the groove. Start at the top, then work your way down the sides and across the bottom.

Thank you for the update. The retrofit kit will probably not only fix your leak but also dry your dishes much better.
