I just read a repair manual for. UO stands for Vent Open (the display can't make a V so it makes a U). The active vent is not closing when it should be closed the gasket is stuck up in the assembly so sometimes it can seal and sometimes it will not and thus the error. if the machine is still under warranty,You can have the vent replaced at no cost .

If not you will need to have a hands on tech on location remove the dishwasher and access the vent for the cleaning and replacement of the vent gasket.

The vent fan is on the top right hand side at the back of the dishwasher has wires coming down the side. Once I had tthis problem the wires were not conected they had to be plugged in. The Er uo code stopped flashing and the dishwasher started working.
You need to remove the dishwasher to access the vent and fan. Check that the fan wires
are pluged in too.

This is what the manual says about your problem.

When in a wash cycle the control does not receive the proper indication that
the vent is closed. The control will try to reseat the vent if after 5 attempts
the vent does not close the failure will appear. The cycle will not start.

I am uploading a copy of the manual for your retrival. It has complete diagnostics, disassembly, and repair proceedures.

Got to page 12 for the information you need.
