I keep getting either SUDS or the F35 code. I finally was able to get it to run so I ran it without detergent. Now I tried it again and it is back to SUDS again. Any ideas?

Maybe this will help, but I'm not sure

Condition:
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.

Check:
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 connectors to the Drain Pump, Pressure Switch, and Central Control Unit (CCU)
Check/Clean Drain Pump Filter of foreign objects
Check Drain Pump
Check Pressure Switch
Check CCU

Dado

Too much detergent or wrong kind of detergent. If you use non HE detergent this will happen. You can remove the excess suds by running a cleaning cycle and adding cooking oil. The detergent will attatch itself to the oil and remove all soap residue, add an extra rinse to the cycle. Also run it empty.

F35 (on some models)



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 fi ll 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.

Suds and F-35 means yall are using too much of the HE detergent or the wrong stuff (non HE)

F35=ANALOG PRESSURE SENSOR FAILURE

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

More:
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.

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.




Don't replace this dude (item 20) $86 till you know the soap problem has been remedied.
What other pearls of wisdom do I have? Let's see
Oh yeah the pump, if it has junk in it then these errors will sometimes pop up so...
it will not hurt to check it
Duet HE Service Manual Note: use the tech sheet in your washer for diagnostics and this manual as a ref to repair and replace stuff. I thank you.

Hi dear.I may have solution for the SUD error.You can give it a go.But I do not know any thing about F35 one
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.

Potential Causes

• 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

Replace failed component.

As it says run couple of rine cycles it should get back to normal.I hope that helps you.Thanks.

I would put bleach in the detergent slot, run through each cycle. Then run the cycle again with just water. These are really touch when using detergent. Just a little bid of suds sets these things off.

? If too much detergent was used: —Run the unit through a Rinse/Spin cycle. —Run a Normal cycle without adding any detergent. This should clear the unit of the excess detergent. 1. Check the drain hose and make sure it is not plugged or kinked. 2. Unplug washer or disconnect power. 3. Check wire harness connections to the drain pump, pressure switch, and Central Control Unit (CCU). 4. Check/clean drain pump filter of foreign objects. 5. Plug in washer or reconnect power. 6. Check drain pump. 7. Check the pressure switch. 8. Verify CCU operation by running a Diagnostic test or any cycle.

F35,= SUDS

set a few washes without using any soap to flush the pump out.

Use less detergent and use a liquid rather than powder.

Sometimes the SUDS/F35 is because of TOO MUCH detergent. To clear you have to set the cycle on rinse and then keep pouring cups of water into the detergent container as the cycle is going. You might have to do this a few times because if the SUDS message comes up the water flow will stop. Just unplug and try again. Also when the detergent container is finally clear you will see the little rotators gears move around when the cycle starts.
