At some point during the cycle a warning comes up regarding too much suds and starts to leak water. I tried draining all water and just running a cycle without soap but still had problem. My husband has come upon it both times so I do not know exactly what the message says. He just shuts the machine off and sops up the water on the floor. There does not actually seem to be a blockage since it drains when I set it to "drain". From the day of installation, I have used the pre-packaged (Cascade) soap packets, since some family members have a tendency to overkill with the soap otherwise. Any thoughts on this or do I need to have a service tech come look at it?

Affectionately known an an analog water pressure switch

ANALOG PRESSURE SENSOR FAILURE
If this failure is displayed, there is any malfunction of the steamer
component detected by the Steamer Electronic Board.

Possible Causes/Procedure
Check if pressure hose is fixed correctly.
Check if the airtrap is not blocked.
Check if the hose is not blocked.

Make sure you are ONLY using HE SOAP!
Correct usage amounts are as follows:

Regular HE SOAP = 2 Tablespoons
2X HE SOAP = 1 Tablespoon
3X HE SOAP = 1 Teaspoon

The information on the soap usage comes directly from Whirlpool Tech Line.

SUDS LOCK (OVERDOSE OF DETERGENT DETECTED DURING THE
WASH CYCLE)

If suds are detected continuously by the pressure switch during the drain
or spin phases, the washer will fill 4 liters of water and during 5 minutes
the unit will rest without tumbling, the water will be drained and it will try
to spin or drain again.

Possible Causes/Procedure

If too much detergent was used:
Run through a RINSE/SPIN cycle.
Run 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.
Unplug washer or disconnect power.
Check wire harness connections to the drain pump, pressure switch,
and Central Control Unit (CCU).
Check/clean drain pump filter of foreign objects.
Plug in washer or reconnect power.
Check drain pump.
Check the pressure switch.
Verify CCU operation by running a Diagnostic Test or any cycle.

Hello, W/D here.

Sd is the error code for suds lock. If suds are detected continuously by the pressure switch during the
drain or spin phases, the washer will fill 4 liters of water and during 5 minutes the unit will rest without tumbling, the water will be drained and it will try to spin or drain again. The SD code indicates the possibility of too much detergent being used. Run a rinse and spin cycle to remove detergent residue. Then run a normal cycle without detergent.
Items to check if it is occurring at the end of the cycle would be to check the drain line and waste outlet for plugging or kinks and check the wiring harness connections to the drain pump, pressure switch and CCU (Central Control Unit). It may be necessary to check and clean the drain pump filter.
Best regards, --W/D--

HI- Ah yes, the suds. Your flood switch has probably been tripped. Unplug the machine or flip the breaker. Remove the lower kick panel and you'll see the white plastic bottom of the dishwasher pan. This is designed to catch the water (or suds) if there is a leak or the water (or suds) over fill it. This will take awhile but get some pliable rag and carefully put it in the space between the bottom of the dishwasher and the pan. There is a styrofoam float on the left side about halfway back, this has to be down for the dishwasher to advance the cycle and get out of drain mode. Just keep soaking the water up (you kinda have to go over the plastic lip of the pan and down wherever there is an opening large enough to get the rag into. Once it is pretty dry it should run ok. Regarding the suds. If you get the machine to run ok then start a rinse cycle and once the water is done filling open the door and add about 4 tablespoons of any cooking oil to the water. Shut the door and let the machine run for about 10 seconds, open the door check to see if there are still a lot of suds, if so cancel the cycle to drain the machine and repeat. Hope this helps, good luck.

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.

You most likely have a bad water fill valve. The suds warning is likely because it is too full.

Try cycling the washer a few times without a very small load of clothes and no detergent. I assume that you are and have beenm using only HE type detergent and I suggest you try using about 1/2 to 1/3 the amount called for until your system is purged of any and all remaining detergent in the lines. Here are the manufacturers reccommendations to address your problem..

“SUD” (Suds Routine)
When excessive suds are detected, a suds routine
automatically starts. This routine removes extra suds and
assures proper rinsing of your garments. “SUD” is displayed
during rinsing and at the end of the cycle to inform you that
Suds Routine was activated. Use only HE (High Efficiency)
detergents.

Hope this helps you..

“F02” (Drain Problem)
Select PAUSE/CANCEL twice to cancel the cycle. Unplug
washer or disconnect power.
Check the following:
Is the drain hose kinked?
Is the drain hose frozen?
Is the drain hose clogged?
Is the drain hose more than 96" (2.4 m) above the floor?
