So after bringing this beauty home, I connected power and a drain hose and filled the dishwasher with hot water (after making sure that the motor and blower worked. They do). I started the machine on regular cycled. The timer advanced perfectly, and it had to heat the water for about 5 or so minutes.

Then it took off washing! I'm very impressed with how quiet this machine is. However, I'm looking at the floor (it's still in my garage), and there was a tiny drip of water. At first I was thinking maybe the gasket was dried out, and just need hot water to set in the sump. So after the draining the machine, I got a closer look where it was leaking.

It's on the side of the sump tank area. Could I just sand the rust and apply some type of sealant, liquid solder, or epoxy?

Thanks everyone! You guys are great and I have learned so much.

I think if you sand it and slather some JB Weld on there, you'll be fine.  I love that stuff!

Funny you mentioned JB Weld. I was just looking at that. I'll get some tomorrow and give it a try. Thanks!

JB Weld

Get the two-part kind that you mix up.  It contains metal and can even be sanded once it has set and dried.

The tub is rusted through where the sump gasket meets the tank, fixing it from the outside is only going to work for a while till it rusts more and in more places.


If you want to keep this DW for long, remove the motor and pump and clean and dry every thing and seal the sump gasket to the tank with 3M Marine sealant [ it will never leak again ] if the sump gasket is in bad shape or puckered replace the sump gasket before reinstalling the pump and motor.

That's an even better idea, and more effective.
