The "SUDS" or "SUD" error can be caused by too much detergent, improper detergent, drain pump/drain line problem, or pressure switch malfunction.

1. If you are not using HE detergent, you need to be. These washers are designed to use HE detergent which is formulated for wash tubs that use 5 to 7 gallons of water. If you use regular detergent, you are, in affect, placing a higher concentration of detergent in the washer that is normally formulated for wash tubs that have a 35 gallon capacity. The manufacturer should have a disclaimer in the owner's manual explaining this. In most cases this will also void your warranty. NOTE: Prolonged use of the wrong detergent can damage the drain pump components and or wash tub seals.

If you are using the correct detergent, double check the label to make sure it is not double (2X) or triple (3X) concentrated. You could still be placing too much soap in your wash.

To get rid of excessive detergent, place the washer on a RINSE & SPIN cycle, then run it through a normal wash cycle with NO detergent added. You may have to repeat these steps depending on the amount of detergent used.

2. If you do not have a detergent issue, double check the drain pump and drain lines to ensure they are not obstructed in any way. Click on the following link for step-by-step instructions:

Obstructions in the drain pump and/or drain lines can attribute to air getting trapped in the drain pump and cause the error code. Double check all electrical connections to the drain pump and Central Control Unit (CCU). You will need to remove the top panel of the washer to access the CCU. This is accomplished by removing the three screws in the back of the washer that hold the top panel in place. With the screws removed, slide the panel back, then off. The CCU is located directly behind the wash tub in the center of the washer. The Drain Pump connector will be the 6th connector (facing from the front L to R) in the center of the CCU.

3. Check the Pressure Switch to ensure it is good. The Pressure Switch is located to the right of the CCU as you are looking from the front. It is a small cylindrical shaped device with a connector plug and an air hose attached. The switch can be checked at several water levels by removing the plug and taking resistance readings at the connector pins. Readings are as follows:

(Pins are numbered R to L facing the from the REAR)

Pins 1 to 2 (SUDS Detect) - 0 ohms
Pins 3 to 4 (Overflow) - 0 ohms
Pins 4 to 5 (L1) - 0 ohms
Pins 4 to 6 (Empty) - 0 ohms

Why Is WHIRLPOOL Duet & Duet HT washing machine showing ?Sud? error code on...


The error Sud is shown on the display due to Overdose of Detergent detected during the Wash Cycle in the washing machine.
In this problem check the MCU in the washing machine. The motor control unit senses a suds lock. Also check the Drain pump for any blockage or the heavy load in the washing machine. or over quantity of detergent is added to the machine and that is got blocked.
This will Help. Good Luck.

Machine read sud


SUD means too much soap was used. Run the washer with a few empty loads and no detergent and the SUD should go away.

What does SUD mean?


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.

My kenmore washer showes sud code


If it is similar to the Whirlpool duet,

Try using less soap (hi eff machine)
try using more fabric softner
to clear the occasional Sud warning, I run the machine on "quick wash" with no detergent/additive. gives it two more quick spin cycles in 30-35 minutes, usually clears it.

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.

Frontloader shows SUD but no visible suds ....then machine stops working. also shows F34 numbers. Have tried resetting by un-plugging . then works fine for a few times then shows SUD again and we have to...


You may have a clogged drain filter.
Remove the bottom front panel to access the filter. Unscrew the filter,clean and replace the filter. Also,run 2-3 wash cycles with no detergent at all.
When using HE detergent,use the exact specified amount. With front load machines more is not better.
