SOURCE: My washer is alarming "suds or blocked pump"? What can I do?

Plug off the power cord from the wall mains. I give you several alternatives, sort out thru the easiest: Note your brand and model. Check on YouTube for change of motor brushes. Then disconnect your motor and check your brushes; follow noting how you dis-assemble so you can re-assemble easier. If your brushes are less than half an inch long get new brushes (thru this very site Fixya) and refit; actually this is quite easy. The spin has a lot to do with worn motor brushes. Manufactures want you to dump machines and buy; it helps them all. Not you - you shell out bucks.
If you have already cleaned out your filter, which is usually just under the tub (be prepared for a lot of water; and disconnect from the wall power socket), your washer still may not spin. So look into next para below. The tech sheet is usually taped to the body of the washer inside somewhere.

Check the motor housing for an overload button, usually on the back and coloured black or red. Give it a push and if it clicks then the motor might have just been overloaded and shut itself off.
There is a big connector located at the motor - giving power to the motor (located under the tub) to the right side, could be loose. Disconnect the connector and refit to make sure it is tight. Before refitting the back, etc, try the spin alone; if it works you are done.
Click if helped pl, at my solution. I am doing this for the enviro. (& you)

A typical HE3 Kenmore Elite washer the F09 code indicates and overflow has been sensed. This can be because of suds or a failure of the pump or pressure switch.

Suds is a common problem with the newer 2X-3X super concentrated detergents.

A pump that is partially blocked might cause this error

The "SUDS" code appears at the end of every wash

If the suds error starts happening suddenly even though you used the same HE detergent and amount that you always have in the past, you probably don't have a excessive sudsing problem, caused by the soap. The most common problem relates to the pump. Some foreign item blocking the inlet of the pump. Foreign objects can make their way down to the pump and either clog the entrance or enter and damage the pump impeller.

Gives code f02 and sud


The F2 error codes means LONG DRAIN TIME and the suds code the washer detected water in tub after normal alloted drain basically the F2&SUDS means the same thing. A lot of times when it does not drain fast enough,its caused by a blocked filter on the pump being biult up with debris. This tip i wrote will show ya how to clean the pump filter.

On a Kenmore Elite Model #11047781700 we keep receiving the error code SUD and F35. We are trying locate the drain pump filter. Could you please tell me where this item is located.

2 possible solutions:
1. Make sure small black hose connected to pressure switch is clear of obstructions by blowing through it
2. Replace pressure switch located at back top right of machine under top hood.
3. Make sure drain catch located at thebottom front behind the panel held in place by 3 screws is not blocked. It is the large white knob which can be removed by turning it counter clockwise and removing the tray to check for any items blocking it. Make sure you have towels in place to absorb any water when you remove drain catch
There are 2 videos on you tube taking you through these 3 steps

Washer machine will not drain

Check for clogging in your drain hose, block inthe ddrain valve/ drain pump and foremost the voltage to the drain pump must be present when the machine program is reached.
If not the controller can be defective.

Washer is flashing the word sud

Hi, here is the meaning of the SUD error code and the corrective actions. If you have any other questions please feel free to comment. Mike

"Sud" 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.
  • 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
