It is unclear which model number you have, but in general U3 fault would mean the pump cavity is blocked. It could be also linked to water pressure setting on dishwasher not set at correct level for your mains pressure.

Refer manual on page 33

It is most likely a fault with the keypad mebrane on the dishwasher control panel. Need model number of dishwasher to make a more detailed conclusion.

error message says ou-what does that mean?

uo means that the vent isnt closed

it means the water is trying to heat up and it is taking longer than normal. Check your hot water heater to make sure it is heating properly. Do not use hot water in other areas at same time ..ie: washer, shower, etc. The HO will disappear once the water is heated to the proper level by the dishwasher.

I have a similar problem with my Frigidaire FDB4050LHS1. My Owner's Manual says to contact the Customer Care Center if the display shows "Er", "uF", or "CE". When I called them, Maria didn't have a clue what the codes meant - all she could do was give me phone numbers to authorized service centers in my area.

I managed to get ahold of a "SERVICE DATASHEET" P/N: 154718601. The error code "ER/ER" means there is a "switch failure"; "ER/CE" denotes a "Configuration Error"; "ER/uo" means "Vent will not close"; and "ER/UF" means "Fan not running".

The schematic only labels three switches - labeled "USER INTERFACE SWITCH", "DOOR SWITCH", and "FLOAT SWITCH". There is also a switch in the pump motor assembly. If either the door or user interface switch is faulty, then you probably won't be able to do anything other than call a repair service - unless you know how to replace these switches yourself.

If the float switch is causing the error, you might be able to run the "Water/Service Test". From "PF" (denoting a Power Failure) or idle mode (with no lights on whatsoever), press and hold the "DRY/AIRDRY" and "START/CANCEL" buttons at the same time for 3 seconds. This will start an 8-stage test that runs for about 7 and 1/2 minutes. The display will show which step the test is in until it shows an error code. Step 1 tests the water valve, which is where the float switch is located. If that switch is bad, you will likely see "Uo" displayed within the first minute of the test.
