Check between door boot seal and drain hose in basket. If this is clogged with lint or sock, towel it will code f35 or sud
Outside the normal analog pressure sensor (APS) / hose checks...
Another cause for the F35 and SUD error could be your CCU (control unit). There are components that seem to fail over time and cause the F35 and SUD errors. You can replace those components yourself now...
See f35 error for more information.
I hope this helps and let me know if you need more assistance!
F35 - ANALOG PRESSURE SENSOR FAILURE
If this failure is displayed, there is any malfunction of the steamer
component detected by the Steamer Electronic Board.
1. Check if pressure hose is fixed correctly.
2. Check if the air trap is blocked.
3. Check if the hose is blocked.

Hope this helps. =)
WARNING: THIS WRITE-UP IS COMPLETELY MY OPINION BASED ON MY EXPERIMENTATION WITH THE EQUIPMENT. TRY ANY OF IT AT YOUR OWN RISK. YOU WILL BE SOLELY RESPONSIBLE FOR ALL THE CONSEQUENCES (GOOD OR BAD EITHER WAY) THAT YOU MAY REAP FROM THE MACHINE YOU WORK ON.
I made the biggest mistake of taking the whirpool WFW9600TA01 from US to India - I had been totally frustrated with the SUDS/F35 issue, absolutely as explained in the question above.
I started as a novice but feel very confident to write this solution now. There are several areas that could cause this problem. Fundamentally, as the water fills the tub, the pressure form the pressure switch is sensed. If the value is not in line with what is programmed, you get this error. This deviation in pressure value can be caused by any of the below reasons.
First and foremost thing I would do is remove (disassemble - note very carefully the assembly and the position before disassembling. You will need to reassemble in the exact same way in the exact same position) and clean all the pipes, hoses and connectors
Details:
The problem could occur because of:
1. True suds formation due to wrong soap usage (pretty often the problem) - Solution for this? - use a lot of vinegar and a few "risnse and spin" cycles with out any clothes in the washer
2. The pressure switch could have gone bad. Solution - replace the pressure switch (I would do this the last though)
3. There could be dirt collected at the water inlet. Solution remove the water inlet and clean the cup shaped strainer
4. Your outlet/drain pump (the one that pumps the water out of the washer into the drain) may have worn out, there by not draining out all the water. This will leave residual water impacting the next run. Solution replace the pump assembly
5. There may be particle collection such as coins pens, small pins etc in the darn pump inlet strainer causing the drain pump to not work properly and in turn causing SUDS/F35. Solution - remove the front of the drain pump inlet and remove the particles and restart.
6. There is a conical shaped connector connecting the outlet of the tub to the inlet of the drain pump. At one side of this connector (the broader side connecting to the tub) there is a plastic ball in it. If the ball is punctured, water may have collected in it causing it to weigh more than what it is supposed to. When the drain pump runs, the weight of this ball may counter act to not allow proper draining of the water. This residual accumulation of the water will cause SUDS/F35 in the next cycle. Solution - replace that flexible connector. Atleast drain the water from the front at the drain pump inlet, if you want the washer to work for that cycle.
7. There is a small white plastic tube at the back which runs a black tube to the pressure swtich. The assembly is pretty interesting. It is a simple insertion with the air tightness being achieved by a simple rubber gasket covering the insertable part (do not know why the design is such). After a few washes due to the vibration generated by the tub during wash, this gasket can move causing air leaks. Such air leaks do not cause any issue to the current run, but will result in a SUDS/F35 in the next run. It will remain so for al the next runs unless it is re-inserted properly. Solution for this? every time open the rear and make sure the plastic white part is pushed in well.
8. There are other reasons like the main control circulatory / mother board could have gone bad etc. You can figure if this is the problem by running the diagnostic tests for the most part - there is a good chance that only a certified technician can tell you. Solution - replace the mother board (quite stupid huh!!)
9. Finally, the steamer assembly could have gone bad - Although the manual says this, I cannot quite figure out how this would affect the pressure buildup in the tub - I do not know what to do. More than likely if you invite a technician, the person might ask you to replace this assembly.
Try everything - the net effect should be that you have plugged all air leaks. I know some expect to see water leaks at place where air leak exists. That may not be true at all. Good luck with everything.
