Have an FO error on frigidaire dishwasher. anyone knows what this error means?

You can find info on the error code here https://appliancerepairinfo.com/samsung-dishwasher-normal-light-flashing/

Hello friend, thank you for your inquiry!
From the information you have provided you would like to place your Frigidaire dishwasher into a diagnostic mode. I have reviewed the dishwasher and do not show a diagnostic mode available. Based off the information you have provided you may be experiencing an issue with your timer or knob. I would suggest performing a factory reset on your dishwasher and you can do that by flipping the breaker off for at least ten minutes. Since it could be an issue with either electrical components you may need to seek guidance from a professional technician. I hope this information is helpful to you. -Matt

Thank you for your inquiry, Elizabeth!

I see that your Frigidaire dishwasher is displaying an error code of "UL" and you would like to know what it means. A "UL" error code means that your dishwasher is in relay test mode. You should be able to clear out the error code by pressing cancel and holding down the hi-temp button. If that does not clear out your error code I would suggest performing a reset on your dishwasher and you can do that by flipping the household circuit breaker off for at least ten minutes. Hopefully this information is helpful. -Matt

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

Reset it at the household circuit breaker for about 10-15 minutes, and retry.

Inlet water error 1E
Not reached to the normal water level in spite of 10 min. water supply
The Water Supply Tap is closed. The Water Supply is shut off. The Inlet Hose is kinked. The Water Pressure is very low. (below 10 psi) Inlet Valve is OK? The filter of Inlet Valve is clogged by impure water. The Hall sensor is OK? The Impeller of Air Guide is bound.
Take action on Water Supply device. Measure the electric resistance of Inlet Valve. (950-1300 ) Clean the filter of Inlet Valve. Check the frequency of Inlet Water by the Test Mode. Replace the Air Braker.

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.

do you here any relays or the motor run? if not perhaps the fuse or circuit breaker has opened.

Oliversmom, Im not coming up with any information on the model number posted. However on the kitchenaid the F0 E0 is default for no error. Press the cancel button to put the range in idle state. Then in this order press cancel-cancel-start. See if an error code comes up different from the F0 E0. The F0 is what is throwing this whole deal off. If it was F1, F2, F3 etc...it would make more sense. See if you have a complete model number you can post along with the error code after doing the above key dance. We'll see if we can solve the issue....Catriver..post back.
