Question about Frigidaire 24 in. PLD3465REC Stainless Steel Built-in Dishwasher
It's 30 days old and just started giving me this error code. It fills with water then pops the error code and progress past that part. Error code ER then UO.
So far so good. I fixed mine by removing the vent and even though it says no repairable parts I disassembled it then removed the rubber gasket and cleaned it with a brush under hot water. I then cleaned the plastic ring it seals against. Next I removed the spring and stretched it to make it about a quarter inch longer and then reinstalled the spring then the rubber gasket and then closed up the unit. So far it is working fine. I suspect the real problem is that there is a tiny sensor that needs to be covered when the vent is closed. If this is not covered the uo error code is generated.

I had the same Er uo problem. I work at LOWES and asked my Appliance manager for help. He said that it was the control Panel, wich is the same thing the 1-800-944 number said. THIS IS NOT THE CASE. He did give me a hint by suggesting I open the door and take the panel off. I did and low and behold there is a paper with scematic and code definitions cliped inside. After reading that the Er uo code means vent open (and comfirming that from a tip i found on this site. I also read that the vent is located in the upper right hand corner of the top of the unit inside. I twisted the GRAY CAP off and saw the black rubber vent i pulled down and noticed it was glogged with soap. I pulled the dishwasher out and took the vent out and cleaned it and then put everything back together. then ran the dishwasher. it ran with no problems for 30 min. then flashed the same Eruo problem. my thought is that the Vent unit has to be replaced i will post more as i find out.

Error code "ER" then "uo". Top right of washer is a vent. reached in and ran finger around gasket, removed a small amount of gunk. Pulled down on the plate that holds the gasket a few times which reseated it. Closed washer and now works fine.thanks Chance_ 020! Good advice!

UO error code. Cleaning the rubber seal worked for a week. Then the dishwasher would no longer run. 6 years old this dishwasher has been fixed 3 times. I took the vent apart cleaned it. Still getting the error UO. Even holding the vent open or closed no change. the replacement part is 100.00 to much. I can not recommend any one attempt this but I was able to bypass this vent by connecting the orange and yellow wires. The dishwasher now runs again with out error. I would not use the high heat or sanitize functions anymore. But for a basic wash this will work until I can purchase a new non frigidaire dishwasher.

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.

We had the same problem with our Frigidaire dishwasher. 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.

To let you know with this error "UO" the heat element stays on. it melted the lower spray arm of my dishwasher while we were out
Chance_20 is right about how to fix it.
Needless to say were going to buy a new one and it wont be Frigidaire.

Trent Williams is right about checking and cleaning the optical sensor. I have gotten the vent open error several times in the past and just opened it and removed the built up soap clogs and everything was fine. This time it wasn't enough. I cleaned around the gasket (what I could reach) and still had the error. Decided to remove the screws and disassemble the valve and clean everything properly. Re-assembled and still have the error. Information said it uses an optical position sensor. It is a small sensor on the very small plain circuit board on the back of the valve where the thin stem from the valve slides through when it is in the up position (mine was black). I removed the valve again and using a small stiff nylon brush and lens cleaner I scrubbed that black sensor piece very hard and thoroughly. Re-assembled the unit again and it is working perfectly now. How long it will last I don't know (only has 3 cycles on it so far), but it may be worth not buying a $100+ part for a while longer.

I had the same issues. I took my dishwasher out, took off the vent and cleaned the gasket. That did not work. I eneded up opening the unit and cleaning the sensor where the vent arm registers its position on the circuit board with a small wire brush, this seemed to do the trick. I am 10 minutes into a cycle so we will see. I found the replacement part online for $60 and I called a repair person and he quoted me $230 to fix it.
Thank you Internet.

I had the same issue... cleaned the vent as described in earlier post and everything seems to be working fine now... there was alot of dried soad which obviously was causing the vent to stick. Thanks for the help...

Remove the plastic turn ring on the vent at right rear corner and "slightly' pull down on the rubber part and with a wet hand run your fingers around that part a few times and repeat with a "clean" wet hand...do this a couple times then reinstall the twist lock ring....that fixed mine right up.....it had a lot of white chunks that were easy to clean off with wet fingers....no mour ER UO and away it goes....the "clunk-clunk-clunk" was the tip off that it was stuck.....hobbiehubbcapp

The problem is the quick connect that goes to the vent is loose, make sure its nice and tight

I cleaned the vent on the Upper Right top of the inside and it ran. With hard water running through the machine it gets pretty gunked up. The lesson I learned is to clean it more often. I agree though with previous posters that the design is a little chincy for such a machine. Luckily there are sites like these to help, otherwise I would've paid a tech a hundred bucks to come clean some calcium from the little vent.

Tried cleaning the vent, checked the wires,took apart the vent assembly and cleaned the optical sensor with a toothbrush, stretched the spring....Still not working.
Tried Antone's fix.....(jumping the yellow and brown wires from the close sensor)....YES!!! (thx Antone!)
Keep in mind that this "fix" will only trick the machine into thinking that the vent is closed. If the vent ACTUALLY IS OPEN, the dishwasher WILL CONTINUE TO RUN!!!! Water will then be forced up in there, doing all kinds of water damage! This is for diagnostic purposes....or those who like to gamble ;) I wanted to make sure it was the vent and not the control panel as some have said.
My dishwasher ran like a charm! No clicking or stopping. During the dry cycle, the fan runs but the vent stays closed. I DID stretch my spring to make it stiffer tho, so I'm not sure if I had left that alone, the fan may have pushed open the vent?

I got the same error code, U0. My problem turned out to be the electrical connector where the vent fan assembly plugs into the dishwasher wiring harness. It had gotten wet, and there was green corrosion on the connector pins. The vent was closing, but the corrosion prevented the signal from getting through. Cleaning the corrosion off the pins, and sealing the connector with some dielectric grease (used on auto spark plug boots - available at any auto parts store) solved my problem.

Had this "UO" or rather "VO" error code. Found the vent in the inside, upper right. It had some junk on it and in the inside. Scraped it off set the wash program and it took a minute for it to figure things out, then it started. Thanx forum!!!

Tips for a great answer:
Good Afternoon Delia Collins, thank you for your post!
Based off the information you have provided your Frigidaire dishwasher is flashing an "ER" error code on the panel. Typically, the "ER" stands for an error code sometimes to help clear out a false error code you can perform a reset on your dishwasher. In order to do that you would need to disconnect power from your dishwasher for approximately ten minutes.
If you continue to experience an issue with the error code I would recommend contacting a technician for proper repairs. The technician will be able to properly diagnosis your dishwasher and this will help you to avoid any unnecessary part purchases. Hopefully this is helpful. -Matt

Hello Shirley - Typically error code ER01 indicates that a water leak is detected under the tub. Unit will possibly need a hydraulic kit. Try unplugging the unit or flipping the household circuit breaker off. Wait approximately ten minutes and turn the unit back on. Could the error code DF possibly be PF? If so, PF means power failure and you should be able to start a cycle. If the error code continues to display on dishwasher then I suggest contacting a professional to accurately diagnose and repair it.
