I own a duet washer and recently I have been getting a couple of different error codes. one is F-02 the other is sud. Have followed the trouble shooter and it still won't drain correctly. I have cleared the drain hose manually but i read some thing about the drain screen. Do you know about this or have any idea what to do next.

First pull the filter clean out on the bottom front and see what might be in there...and be sure to use HE soap and very little, most problems with front load washers is caused by using  the wrong soap and using too much....might have a sock or something cought in the pump area...

Hi Pegi,

 

We've had our 9100LW for 3 1/2 years and this is the first time we've had  error code 2 and SUD also.  I checked the drain...OK.  We tried a "no clothes" cycle and after the wash cycle it hung-up on SUD again.  We manually put it in the Drain/Spin position and the cycle SEEMED to be OK but the pump ran for what seemed like a long time.  Would the filter be a problem there too?  Bottom front?

 

Thanks,

Ron

I couldn't edit my last message to say I've checked the bottom filter, the inlet and outlet hoses and all were OK! Nothing seemed to look bad in the underside, all clear, no rust, very little dust if any as the unit is up off the floor.  There was just a VERY small amount of lint in the filter/pump area.  Any other suggestions? Please?

Thanks, Pegi,

You must have answered me when I was downstairs taking the front panel off and checking the "stuff".  It was really easy to do with the right tools!  I'll now take some time to read the "directions" :P and see what I can "dig-up"!  THANKS!

Well, some new news...I snaked the drain hose and found a lot of nasty gunk.  No sock though.  I took it off and flushed it and got all but a few dark spots but I can see through the tubing now.

 

I ran the diagnostic test on page 6-8.  Everything went well up to C:06, Drain Pump.  It ran and ran for quite a few minutes (In my opinion, it should've been done in a couple of minutes but it ran quite a bit) and was still running through step C:07 and C:08.  I got a green cycle complete and no trouble code!  Am I wrong in thinking it's the pump? OR could it be the sensor?

 

HELP!

Ron

While I had the top off, I checked the resistance readings on page 5-2.  Empty at 0 Ohms was the reading.  SO, another IF...IF the pump is running and empties the washer (except for what's in the hose) and IF the pressure switch read "EMPTY", could the problem be in the CCU? :?

What say you?  Any other suggestions?

Thanks!

Ron

Still can't edit my own posts (???)

Thought I'd include ALL my numbers of the Whirlpool Washer in question...

Should I have started a separate thread? The owner of this thread didn't specify what unit he had in the header.

Did you disconnect the wiring harness connector from the CCU before making any continuity tests?

Did you disconnect the pressure switch connector from the control box?

Was the washer empty when you measured the "empty" switch?

If the answer to the above questions is yes then the empty water level switch is functioning correctly.

A partially plugged or kinked drain hose or debris in the drain filter will cause the F/02 and SUD error messages.

Does the water flow freely out of the drain hose when draining?

Are you still getting these error messages after cleaning the drain hose and drain filter?

If the pressure switch is function correctly and getting the signal to the CCU and there are no obstructions in the drain hose or filter then I suspect a bad CCU.

Hi Southern,  I'll kinda sum-up what I've done.

I cleaned the pump filter at the bottom of the unit...no blockage Very little lint.

I removed and flushed out the hose from the pump to the top of the washer...some crud but not clogged. The hose to the drain was OK.

Unplugged the connector from the pressure switch AND the CCU.  The measurements were 0 Ohms between 21 & 22  at the pressure switch...same as pins 4 & 6 at the connector at the CCU.  (with connector plugged into Pressure Switch only)

Ran the diagnostic.  Completed successfully but the drain sequence, C:06, ran for quite some time before C:07 and C:08 started AND it continued running through C:07 and C:08.   I don't know if this is normal...couldn't find any info on test results and length of time for each sequence.

Put everything back together and did a small load of "cleaning rags" and very little detergent.  It ran through the cycles OK without any trouble indication BUT, at the end of cycle, (green light), we got a SUD indicator after it shut down and unlocked the door. When we opened the door, the machine reset.

I measured the terminals again and they were the same as before.  "EMPTY".

My wife explained to me she has seen SUD at the end of the cycle (green light lit) after doing a load of towels, and put them through another rinse cycle.  She even uses "Extra Rinse" on most loads.  She uses VERY little soap, much less than the recommended amount and still thinks the machine doesn't rinse as good as it should. 

I haven't heard this before this problem yesterday when the machine was totally “locked-up”...could it be a problem from "NEW"?

As I was typing the other summary, she tried a small load in Normal. It went through wash OK but at 11 minutes remaining during the "Spin" phase, we got "F02".  I could see water in the bottom of the drum so I put the machine in "Drain/Spin" to complete the rest of the cycle. 

Is there a mechanism in the pump assembly to keep water from flowing back from the hose into the drum?

Yes but not in the pump assembly. There is a Eco Valve shown in the service manual on page 3-10.

The F02 error if the Eco Valve is gummed up. I suggest inspect it.

I saw the picture in the manual but where is it located?

I thought that kept water from flowing OUT of the drum during the wash cycle.  I didn't see that under F:02 as a cause.

Thanks

The manual only shows one photo of the valve, it appears to be inside the outer tub, my guess near where the water discharges. It may be near the bottom hole on figure 4-39 on page 4-10.

If the Eco Valve is preventing the water to drain out of the tub, it can give an F02 code. The CCU can't tell if the excess water is due to a bad Eco Valve, plugged drain line, or bad water pump.

I found this a couple of pages back!  I tried it and it worked!  no added water to the drum!

 

I had some time and read through the 68 pages listed in this forum!  BOY, do I need a life!

The following was an excerpt from "SEVEN" and I sure appreciate it!

 

<QUOTE>

A simple way to check "Eco Valve" without dissembling the washer:-
1) Take the drain hose out of the standpipe.
2) With the open-end of the drain hose facing up, pour water into the drain hose until it is nearly full.
3) If the eco valve is good, the water level in the drain hose will remain unchanged.

Please note not all washers have "eco valve". Pouring water into the drain hose of the washer without eco valve is same as pouring water into the tub.<QUOTE>

 

From other posts in the forum, I'm inclined to go with the pump unless I can be proven wrong. 

 

One thread pointed to a broken impeller.  Guess I'll have to take the pump motor out and check it.  Too many things point to the pump.

I have one other question, now I'm thinking again...

The CCU tells the pump to run and I suspect the pressure switch tells the CCU when the tub/drum is empty. The CCU should cut power to the pump after 15 seconds. 

How long, NORMALLY, should it take the pump to empty the drum? 

I wondered about the time element when I ran the Diagnostics.  Step C:06, Pump operation, took a long time (I forgot to time it) for so little water AND continued to run during C:07 & C:08.

I know if it runs for 4 minutes there is a code: SUD (tech manual) Long Drain, and 4 minutes later, a code F:02. (total of 8 minutes)

Ron
