Good evening,

I hope that you and your family are well.

I have whirlpool dishwasher (model WDT790SAYM2, serial number F33009303). Recently, the machine’s key pad has stopped beeping when a cycle is selected, which I fear is a prelude to the key pad dying altogether.

Any thoughts?
Thank you, take care and have a great week.

I checked the owners manual and there is no option to turn OFF and ON beep sounds when pressing the keypad buttons.

So Yes, its possibly the keypad assembly is starting to go bad.

Try disconnecting and then reconnecting the ribbon cables.

Here's the keypad assembly for your model:

Good evening!

I hope that you and your family are well.

So the keypad seems to be still working fine; however, I am out of town and was just informed that about 50 milliliters of water leaked directly beneath the center of the machine onto the floor. I will be home tomorrow evening. I asked my wife not to run the machine and dry the floor.

I was considering running the machine with some blue food coloring to help identify the leak source. Any advice or should I toss the 8 year old machine and get a new (insert the name of a reliable machine)?

Thank you, take care and have a great evening.

Its always best to first find out where the leak is coming from. On these machines I've seen them leak from the diverter seal and from the bottom of the door. But if your wife said directly under the middle of the dishwasher then its more likely the diverter seal, but get a flashlight and lay on the floor and watch where it leaks when you get home.:)

OK- thanks. My wife, it is definitely not the door or the float shutoff (which leaked before until I tightened the sealing nut, as advised here.). She says that it is directly beneath the pump/motor at the center off the machine. Thank you.

So I returned home. I put an old plate under the machine, and ran the machine on one hour wash. About 30 minutes into the cycle, the leak began. Slow drip formed and fell for a few minutes then stopped. I stoped the machine and pumped ‘er down.

I couldn’t seem to time a photo when the drip form, but got three photos with it hitting the puddle on the plate. I guess that that is a leak around the diverted seal that you mentioned previously, eh?

Thank you!

Ok, 2 possibilities either the Motor to Pump seal is leaking or the diverter seal is leaking. See if you can reach your hand in and feel if its coming from the Motor to Pump seal first.

Here's the Motor to Pump seal for your model:

There is a video in the part link that shows you how to replace the Motor to Pump seal.

Here's the sump assembly, which included the diverter seal, for your model:

Sorry- the leak is from inside the white cylinder. It is not leaking from the exterior of that cylinder.

Which part do I need? (My luck, the repairs requires the more expensive, harder-to-install part.... )

Thank you!

That's very odd, your parts diagram does not show that white cylinder.

Here's the parts diagram for your model:

You will need to pull the dishwasher out and take some more photos of that white cylinder.

Yes, that's the diverter motor, so water has gotten into that diverter motor, so you will need to replace the diverter motor AND the sump assembly(in post #7) which has the diverter motor seal in it.

Here's the diverter motor for your model you can order:

You can try to clean up that diverter motor, but once water gets in it, that's usually the end of it, as the water shorts it out inside it.
