Question about Frigidaire 24 in. FDB635RF Built-in Dishwasher
Brand new not 2 months old just started last week doing this
Hi, I am having the same problem you describe above with the model nr PLD3460RDC1. Were you able to find out what it was? Thanks so much!

SOURCE: error code
We had the same problem with our Frigidaire dishwasher (different model though). We called them and they said the UO stands for Vent Open (the display can't make a V so it makes a U). The active vent was not closing when it should be closed (the repairman said the gasket was stuck up in the assembly so sometimes it would seal and sometimes it wouldn't) and thus the error. Since our machine was still under warranty, we had the vent replaced at no cost and haven't had the problem since.

SOURCE: Error code ER then UO any ideas?
The vent fan on the top right hand side at the back of the dishwasher, has wires coming down the side. The wires were not conected they had to be plugged in. The Er uo code stopped flashing and the dishwasher started working.

I had the same problem. I pressed the "Start Cancel" button, kept it down, then pressed "Rinse Only" button. The display then went clear. I pressed "Start Cancel" again, then "83" showed up on the display. I let it run its cycle, then it corrected itself. A little scary, but it worked. This answer board is great!

Probably a control panel failure. This unit does not ventfrom the front like most do, so there needs to be some clearance above the top of the tub to avoid blocking the vent fan, otherwise moisture gets trapped in the machine and works it's way into the control panel eventually.

My unit has the same problem and it is due to a failure of the control board. The tech that came to look at it tells me that this unit vents from the top of the tub rather than from the front, and he claims that the installation instructions require a 1" gap between the top of the tub and the countertop.
Now I have found no such information in the installation manual that I downloaded, and I am skeptical that a 1" gap could be done, and if it could it wouldn't look to good.
I am going to pull my unit out and see exactly where the vent fan is and what the clearance is. The service tech says they can't replace the control panel until the installation is proper. I am thinking this is at least to some extent a design flaw with this machine. There seem to be a lot of reports of this failure.
