Is it SUE or SUD code?
SUDS LOCK (Overdose of detergent detected during the wash cycle)
The motor control unit senses a suds lock condition by analyzing the current draw on the drive motor. If "Sud" is displayed a potential suds lock is detected. This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.
• If too much detergent was used, run the unit through a Rinse/ Spin cycle then a Normal cycle without adding any detergent. This should clear the unit of the excess detergent.
• Check the drain hose and make sure it is not plugged or kinked
• Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
• Check / Clean Drain Pump Filter of foreign objects
• Check Drain Pump
• Check the Pressure Switch
• Check CCU
check your detergent. You should only be using detergent that has the "he" symbol on the front of the bottle. It stands for high efficiency. Its made for washers that use less water so that it rinses completely. If you use regular detergent, suds will be left after the cycle is finished.
I found that mine was having a sud error. I removed the lower front panel and removed the filter. It was full of lint and loose change. I reinstalled the filter and haven't had a problem since. On a side note I found something interesting laying inside. A service tech guide wich stated to do exactly what I had done.
The SUD message usually indicates that the sensor detected excess suds and shut down the washer until the suds subsided. To my knowledge, Zero isn't an HE approved detergent so the amount you use has to be really tiny to avoid the SUD error.
With the Tide HE, you still may be using too much detergent. However, you should check the drain pump and outlet hoses. Sometimes a slow or blocked drain can trigger the error. There is often a filter at the drain to keep foreign objects that were left in the clothes from damaging the pump. Make sure that nothing is in this "coin trap". Have a bucket ready when you take apart the drain to catch the water left in the washer. The pump is accessed through the back panel. (Some front-loaders actually have an access panel so you don't have to remove the entire back.)
If you see excessive suds during the wash cycle, run the washer through a complete cycle while it's empty without using any detergent. This often will rinse out any detergent that may have been left from previous loads.
The code Sd means that suds were detected. Generally this means you used regular detergent instead of the HE detergent. Less often it indicates that you used more detergent than needed for the load.
Remember to use an HE (high efficiency) detergent and to follow the directions for the amount to use in a wash cycle.
The washer should do a suds correction program to make sure that the clothes are fully rinsed. However, if the code remains and the wash cycle dial is flashing, set your washer to repeat the cycle with cold water without adding additional detergent. (Every portion of the wash cycle will be extra rinses.)
This error code indicates that excessive detergent suds occurred during the cycle. If a "Sud" or "Sd" error code is displayed, or if you can see excessive suds in the window: There are too many suds in the washing machine. The washer will not be able to spin out water with the excess suds. When "Sud" or "Sd" is displayed, the washer automatically extends the rinse time to remove the excess suds. During this time, the washer pauses the tumbling and adds water for additional rinsing. This pause allows the bubbles in the suds to break. This pause and rinsing are necessary and may occur several times to eliminate the suds. See the animation below for more information.
If you see "Sud" or "Sd" with the Rinse status light on, the washer is in the process of removing suds. Let the cycle continue.
If you see "Sud" or "Sd" and the Cycle Complete light is on, the washer detected too many suds during the cycle and your load may not be fully rinsed or water may not be fully removed. You may want to select a Rinse/Spin cycle for further rinsing.
SUD means a detection of suds in the machine. These machines are very sensitive to over sudsing. Try adding just plain water or bleach to break down the suds level. They say to use 1/4 of the detergent you would use in an older machine.

Check the following: 1. Is the overfill protection float able to move up and down freely? Press down to release. 2. Be sure the water supply is turned on to the dishwasher.
3. Check for suds in the dishwasher. If foam or suds are detected by the dishwasher sensing system, the dishwasher may not operate properly or may not fill with water. Suds can come from: 1. Using the incorrect type of detergent, such as laundry detergent, hand soap, or dish detergent for hand washing dishes. 2. Forgetting to replace the rinse aid dispenser cap after filling (or refilling) the rinse aid, or spilling rinse aid into the tub (rinse aid causes suds to occur). 3. Using an excessive amount of dishwasher detergent.
Suds? If you use dishwashing detergent you shouldn't get suds. If a small amount of sink type dish soap is left on a dish before loading it into the dishwasher this can happen. I would use several rinse and drain cycles with the racks and dishes removed until the suds are gone.
Never use any type of liquid dish soap made for sinks. The same thing that makes suds in the sink will make even more in the dish washer.
