The codes stand for things that are possibly wrong with the dishwasher so that it is easier to get it fixed or to know if it is even fixable by you.

Here is a list of Frigidaire Dishwasher Error Codes

1. Error Code HO:

This code stands for what is called heat delay, or low water temperature. It is very simple and just means that the water temperature needs to rise before the cycle can start.

2. Error Code LO:

LO stands for low rinse aid, and this is another simple one that tells you that you need to refill the rinse aid dispenser so that it can perform at its highest level.

3. Error Code PF:

This one stands for power failure. This will happen when there is a power outage, or a breaker goes off. To fix this error code try opening and closing the dishwasher door to reset the cycle.

4. Error Code i10:

This code will pop up when the water level is abnormally low for some reason. If this pops up check to see if there is any leaks or clogs in the water supply line.

5. Error Codes i20, i40, iFo:

These all mean the same things. The drain line is restricted, so what you need to do is check the drain line for any holes, kinks or clogs. It is also recommended to check the filter as well and clean them if need be.

6. Error Code i30:

When the i30 error pops up it is saying that the bottom pan has a leak to it. So, what you will need to do is check the hose connections and make sure that the unit is level, so the water goes where it needs to go.

7. Error Code i50:

This one is drain or wash motor failure. What you need to do when this shows up is to restart the unit. This will either mean pressing and holding the cancel button or completely turning off the power at the breaker.

8. Error Code iCo:

Electronic control system failure. The solution for this one is going to be the same as the i5o error. Either restart by pressing and holding the cancel button or completely shutting of the power at the breaker.

9. Error Code UO:

This one is saying that the vent is open. When this pops up the first thing to do is to check the vent assembly and wiring to make sure that everything is in correct order.

10. Error Code UF:

Vent failure or the fan is not running. Same thing as UO you want to check the vent assembly, wiring, and replace the vent fan in order to get it running again.

11. Error Code ER:

Membrane Switch Failure/Stuck keys. This will happen when one of the keys is throwing the wrong signals. Check to make sure that the wiring between the keypad and main control board is in working order.

12. Error Code CE:

Configuration Error. Just like the ER error code the fix for this one is to check the wiring between the keypad and main control board as well.

13. Error Code CL:

This one stands for Close door or the door switch is open. Check all the door switches to make sure that they are not broken or damaged in any way. Once you have checked those then check the connection between the door switches and the main control board.

14. Error Code dP:

This one means drain pump. This one will pop up when you are doing a relay test and the drain pump activates.

15. Error Code FL:

Water valve open. Once again this is going to mostly be seen when you are doing a relay test. This one lets you know when the water valve is activated during the test.

16. Error Code Hs:

Hall Sensor Error. This is an error code for the motor. The way to deal with this is to check the wiring between the motor and the main control board. The next step would be to replace the motor if needed.

17. Error Code rA:

Rinse Aid Reed Switch Failure. The first thing to do is refill the rinse aid dispenser and check to see if the error code went away. If the code is still there, then the next step will be to check the wiring between the dispenser and the main control board. If more is needed after that then replace the whole dispenser assembly.

18. Error Code RE:

Rinse Aid Reed Switch. This is telling you that the rinse aid reed switch within the dispenser is closed.

19. Error Code RF:

This is another error code for the rinse aid reed switch. This one however stands for the rinse aid reed switch is open. Refill the dispenser and if that does not work replace the dispenser assembly.

20. Error Code Rt:

This is the relay/ triac test. This will pop up when you begin the relay test mode on the dishwasher.

21. Error Code Sd:

Sd stands for detergent dispenser and will pop up because the dishwasher is in relay test mode and the detergent dispenser has been activated.

22. Error Code Tu:

Turbidity Sensor Failure. This one will pop up if the sensor has failed and what you will need to do first is to check the wiring between the turbidity sensor and the main control board. Then replace the turbidity sensor if that is what is needed.

23. Error Code i60:

This one is an error stating that there was a problem found within the water heating system of the dishwasher. If this pops up restart the machine by pressing the cancel button or cut power to the machine at the breaker so that it completely resets.

24. Error Code UL:

This one is a relay test code that will pop up when the UL test is activated.

Often the most common problem that you will run into will be power failure, this is under the PF code.

This one will pop on if there is a 10% or more power drop to the appliance.

With this one if it is happening more and more often check that the voltage going to the machine is what it needs to run properly.

The second most common one is going to be the HO code, and this is very common when you have an old dishwasher.

This one pops up when the water is taking a long time to heat up. A good trick to help stop this is to turn on the hot water before starting the dishwasher to make sure that all the cold water is flushed out of the lines first.

The final most common one is going to be the LO error code. This one pops up when the rinse aid dispenser needs to be refilled.

It is the easiest one to fix as you simply just add more rinse aid and then start the cycle up again.

There may be more codes than these as things like dishwashers are coming out with new models all the time. However, these are the most common ones that you will find among all of them.

If there is an error code that is not on the list, contact Frigidaire for more information on what it could possibly be and how they can help get it fixed for you.

  1. I noticed that after running the Water/Service Test on my Frigidaire dishwasher model FGHD2465NF1A some of the expected LEDs did not turn on and after ending the last test step the Clean/Sanitize LED does not go away even after opening the door as the documentation states. The appliance has been turning itself on lately or just stopping after 15-20m of starting a washing cycle, it has also had the “rA” error but the rinse level is just fine. Just before the service test it was showing an “HS”. It looks like many things are failing within a very short period of time. It looks to me like the control board just went kaput. Is there any test I can run to have a better idea if this part is really the culprit before getting one and spending almost $200 that might not fix the issue?

    • For me it sounds like problem with the main control board. Check paper service manual for your model: 1) Behind bottom kickplate 2)On the inner side on the front panel (metal panel where handle attached to) By the way, did you try to flip the breaker OFF/ON?

  2. Frigidaire Gallery model FGHD2465NF 1a I am receiving a code “PL” I was given this dish washer and told it was throwing an “error code” the owner said he could reset it and it would continue to work properly.
    That is all the info I have at this time. I cannot find the above code on any list.
    Do you have any suggestions as to want to check?

      • Mr Smith,

        The “PL” code was incorrect.
        The correct code that appears is “Washing/drying “ER” cleaning “S”.
        This appears a few minutes into any cycle I try to run. The “rinse only” light is flashing on & off also.
        I was given this dishwasher so I don’t have any history other that what I have stated above.
        Any assistance will be greatly appreciated.

  3. Hi Eugene, I have a model FGID2476SF dishwasher, 15 months old, that since about one month instead of shining a green light on the floor at the end of the wash cycle shows the blue light flashing twice at 5 sec interval. The wash cycle is normal. It looks like an error code but what does it mean?

    • better to run diagnostic mode and see what kind of errors stored in the memory. Check kickplate of your dishwasher, there should be service manual

  4. Frigidaire Gallery model FGHD2465NF 1 and I have a situation when I try to turn on the dishwasher a 99 + appears and 10 seconds later it gone. Any help would be appreciated . Paul

  5. Hi,
    I have a FGIP2468UD0A. I’ve been getting ER error code. I have changed the keypad already and it came back. Any ideas?

  6. Hi, I have a FGID2466QF7A, dishwasher will start normal then about 20 minutes into the cycle pop error code Er, I have reset the breaker, I have taken off the door and cleaned connections, changed outlets, any ideas?

    • Er – touchpad key failure. Stuck key or key pressed for more than 1 minute. Check cable between keypad and control board. If cable is ok, replace touchpad

  7. I just installed a brand new dishwasher and when we turned it on for the first time it filled up with water, and code i1 came on and machine drained. I tried again and opened the door after it filled and there appears to be plenty of water in the unit. any ideas?

    • Hi James, i can’t find info about i1 code, but i10 code means low fill has been detected. “Look for a pinched water supply line, or water shutoff is not completely opened” By the way, how long does it take to fill the dishwasher?

  8. PLD2855RFC1 Frigidaire dishwasher error CL but the door closes and clicks into place. Will start to run for a few minutes then shut off. Will also show code PF intermittently. Not sure if I should order new latch and start there?

    • Check power connection in the junction box, bottom right side, but dont forget to TURN POWER OFF. Seems like a bad connection there, if you had random PF code

  9. I have an Frigidaire dishwasher, model number FGHD2465NF1QA, serial number TH24381442. when I turn it on and clear the PF, and try to run it, the dial shows the number “17” for about 10 seconds and then goes off. Any ideas?

    • So, its not even turns ON? Hmm.. Unfortunately, i have no information about number “17” and what is that mean. Actually, did you check for the service manual behind kick plate?

    • Well, if its not draining then check the drain pump (make sure nothing got jammed drain pump impeller) and drain hose connection to the sink.

  10. Code just says 48 and is frozen. Turned off breaker for well over 10-15 moinutes for a reset; power back on and it displays 48 and is unresponsive.

    • Sorry, i dont have exact information about error 48. But i can guess, it related to i40 error code – Pressure sensor error. Maybe its clogged and control board not sensing how much water entering dishwasher

  11. Error code “uo”.
    The code explanation indicates a vent is open… is that the “blower vent”?
    If so, what can I do? Or so I need a technician? Or, if not what vent would it be?

  12. Hi, I replaced the pressure switch on my Frigidaire Professional dishwasher twice thinking that the replaced switch might be faulty but still get i20 error.

    Have cut power for 5 minutes to reset the machine but still the same. Can you please advise what could be the reason?

  13. Hello

    I have a new 18 inch Fridgidair dishwasher. It stopped before the cycle has ended and shows error code i 4. I have tried to clear by holding the resent/clear button for 3 seconds
    and turning off the power for 15 mins. Still stays on i4 error code. What can I do ? Thanks

      • Hi I’m getting the same error code!
        My installer forgot to remove the stop plug in are disposal. I removed it but the dishwasher will not clear the code! It also draine’s water and stays running for about 20 sec even if I open the door.
        Any help please

        • If the drain pump running even with the door open, then 1) Door lock is malfunctioned or 2) Dishwasher have a leak

    • Try to reset dishwasher by pressing Cancel button or turn dishwasher breaker off for a couple of minutes. If no water comes in at the beginning of the cycle, check water tap under the sink. If tap is on, probably inlet valve failed or just clogged due to calcium buildup inside the valve.

  14. Hello – I have frigidaire ffid2466q5a. When I run it, the water fills up, the latch white witch under the dishwasher works and water filling stops when the switch is. Then the dishwasher goes silent for 3 minutes and then the water drains out. The draining and filling works. I also checked by opening the dishwasher bottom to check if any hair or plastic is stuck near the impeller and nothing. Please help if this is circulation pump, wash motor or control panel issue?


    Will not start Showing a Code of Ioc however when I look up the codes I cant locate that code. Thee is a Ico but the display is definitely showing Ioc

    Any ideas or suggestions would be greatly appreciated


  16. Would HO error code explain not drying dishes? My cycle gets down to last 35 minutes or so, but then gets stretched out by fairly long intervals where just HO code shows on display, and then counter picks up with say 34 minutes. So, like a 90-minute cycle turns into 120-40 minutes. Thanks.

  17. I have a fridgedare dishwasher getting error code 30 , does the drain hose have to loop around around the back of the appliance

  18. Hi Eugene we have a Frigidaire dishwasher and it isn’t going through the wash cycle everything else seems ok
