Hi,

I took off the bottom panel, and was able to find the area where the leak is coming from, but not able to pinpoint what exactly the source of the leak is? does the attached pictures help in anyway? this picture is from underneath the dishwasher.

will really appreciate your help.

You need to remove the motor/pump, and replace the rubber seal gasket that's around it that's likely leaking. Not that hard to do, but very involved:

No, there are only a couple of ways to tell for sure. One is to pull it out, and run while looking with a flashlight...dangerous if you touch the wrong thing. The other is to use an Endoscope, a flexible shaft camera that connects to a smartphone and you can move around underneath and look for the source. Most often it’s going to be the city water connection coming in, or the drain water connection going out. Those were both connected by the installer and more likely to be failing than an internal part. It could be the pump seal, but I would verify before spending any money on parts.

The photo is from internal parts in the center, it's highly unlikely that drip on that plastic ring came from leaking hose and if it was should be very easy to determine that. Hard to tell but it appears there is rust stains above it to the left.



If it were me I'd watch the video or find manual with diagram and see where it is they are assembling any gaskets. Tighten screws/bolts slightly where exiting one is first and see if goes away. Gaskets are tricky, you do not want to over tighten them because you end up crushing it where the bolt/screw is and that will also cause leak. If you can't get it to stop leaking by tightening it and get it apart if the gasket doesn't appear damaged I'd just hit it with a bead of silicone and reassemble.

Good deal! It wasn't really all that hard to do either, was it? I had to do the same thing about 5 years ago.
