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 Jodi, thank you for your post!

Based off what you have described your Frigidaire dishwasher is displaying an error code "CO" and will not run. An error code of "CO" may be a miscommunication within the control panel and you can clear that error code by disconnecting power from it for roughly ten minutes. If you continue to experience an issue with your dishwasher I would suggest contacting a professional technician for a diagnosis to be completed. I hope this information is helpful. -Matt

Hello friend, thanks for your inquiry!

On your Frigidaire dishwasher "i30" stands for aqua control. You should perform a reset on your dishwasher and that could clear any false error codes. To reset your dishwasher you can flip the household circuit breaker off for ten minutes. If that does not work you could be experiencing an issue with your water inlet valve or control panel. I hope this information has been helpful. -Matt

Hello Ermellina, thank you for your post!

If you are getting an error code "F0" on your Frigidaire dishwasher, it usually means that you are experiencing an issue with the water level. To clear the error code, you can reset your dishwasher. However, since you have already turned off the circuit breaker, at this point, I would recommend connecting with a professional appliance tech for a clear-cut diagnosis. Best - Z

vent is possibly open during the wash cycle. main control is not receive signal from vent assembly.
verify the wiring between vent assembly and the main control board. If wiring correct,replace vent assembly. the main control may need replacing if the problem still exists after replacing the vent assembly. this should be performed by a trained technician.
