Why do I keep getting ul code

You can try to clear the Error Codes;

Unplug the washer for 10 to 20 minutes.

Disconnect the U.I. (touch pad).

Plug the washer back in for 1 to 2 minutes.

Unplug the washer.

Plug the U.I. back in and then plug the washer back in. Codes should then be cleared.

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.

Before replacing, I would go over the board and check for loose wires. Then try a repair looking for cold solder joints. https://www.youtube.com/watch?v=h5_dBMuJ...

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.. Check between the basket and tub for foreign objects such as socks or other small laundry articles.
