You can try to clear the Error Codes;
Most of the time if no mechanical faults can be found the CCU (Central Control Unit) needs to be replaced. I would recommend running the diagnostic cycle first (see image below).
This is a very labor intensive do-it-yourself project, it involves extensive tear down of the washer. If you are not already sure you can perform these checks safely and competently, refer this work to a qualified professional. Working with live electrical current can be very hazardous and possibly deadly. Testing voltage output requires working with electrical current. Do not attempt these measurements without the proper tools and safeguards.
First you will need to see if the washer gives that "UL" error while running the washer empty.
Start a load with nothing in the washer. If the "UL" error comes up there is a mechanical issue or bad CCU. If the "UL" error does not come up there is most likely a loading issue. A common problem that causes a "UL" error is mechanical friction. I.e. something keeping the basket from moving as designed. You will need to remove the basket from the tub. I have included an illustrated set of instructions (See below). Check between the basket and tub for foreign objects such as socks or other small laundry articles.
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
