Hi please go to this above link, it is all explained at length what is going on and what to do.

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.

If you see "Sud" or "Sd" with the Rinse status light on, the washer is in the process of removing suds. Let the cycle finish

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.

Indicates "too much suds". Be sure to use only detergent with "HE" on label. Regular detergent sudses too much in a front load. Also, be sure to not use too much.

Remove the bottom front panel. Clean out the drain filter located in the front center.
Replace the drain filter.Run a cycle with all COLD water.

I;ve had the same problem (SUD on first fill) and found this most helpful for my WFW9600TW01 Duet washer

I duplicated his actions and it cleared up my SUD/F35 error. I think running the diagnostic test multiple times flushes the sensors/sensing lines to eliminate the problem.

F35 has to do with the pressure switch which is located under the top panel on the back right. It will have a little black hose hooked to it. This happens when SUDS or detergent somehow gets up into it and usually locks unit out. Only solution is to replace pressure switch. You can find the tech sheet behind the bottom front panel usually tape to the back side of that panel or taped to the bottom right side inside unit. Hope this helps

My manual says that Sud means that you are using too much soap. The washer will say this mid cycle until it gets rid of the extra "suds" and should then resume the cycle. If it doesn't, then you have a different problem.

sounds like you have a clogged/bead pump. removethe lower acess panel and from there youll see the pmp clean put remove thescrewout, and clearthe debris. BE WARNED THER WILL BE WATER BEHIND grab a towell or 2

Hey I have mine appart right now and the pump is busted, with a sheared keys on the impeller shaft. If you get it appart and can pull the impeller shaft out of the armiture you have sheared keys; this shaft should be nearly impossible to remove if the keys are still good. Mine look to have been a bit rusted. Likely cause is inferior steel succoming to bleach; which we use all the time to rid the washer of the persistant mildew.

Al the robot guy

yes I can the suds is from too much soap it will go thru a flush cycle and should go away after 4 min of opert. let me know if it does not clear you may also get a LD code on the machine to clear press cancel twice
