Well, we fixed the Duet gas dryer thanks to this site in late 2007; guess the washer felt left out as it's needing attention now.

The problem: It doesn't drain completely, on any cycle.

What I've done so far:

1: Argued with the me'm sahib (that was NOT productive!)
2: Pulled the bottom panel and oooh'd and ahhhh'd.
3: Unscrewed the pump filter/cover to check for flotsam/jetsam.
4: Found only one (1) dime and one (1) straight pin. (?)
5: Pulled the pump and removed the motor to check for any surprises (none)
6: Put it back together and ran Drain and Spin cycle. Still water in tub.
7: Ran diagnostics; no apparent trouble codes (actually, put this back up towards top)

Now, according to the manual, no water should be introduced during the Drain/Spin cycle. We observed water entering the tub starting at about the 3 minute mark.

Just finished the Rinse/Spin cycle and it is indistinguishable from the Drain/Spin, i.e., at about the 3 minute mark (when, to my mind, it should not be adding water but spinning like crazy to eliminate it), it's adding water, up to and including the 1 minute mark. So, at the end of the cycle, the laundry is sitting in water.

So, do you think we're looking at a control module or a rotary switch or...?

Many thanks for any help coming our way!:yikes:

I always like to get some eyeballs on the actual drain discharge stream; make sure it's the same diameter at the hose and should be very strong.

Even with water spraying in during the drain cycle, that pump and drain system have way more than enough capacity to drain that water. Water entering the drum isn't the problem; the problem is not enough water leaving the drum.

I'll run it and check the flow/stream. Could we just be talking about the drain pump? The pump motor runs at seemingly the appropriate time...maybe the pump itself is worn if the stream is not strong? Washer is almost exactly 4 years old: January, 2005.

Ok, here's the deal... Running the Drain/Spin cycle again and observing the discharge hose flow, the cycle starts at 12 minutes, the tub starts to spin, the pump motor comes on and the water in the tub is discharged out the drain hose in a strong stream/high volume/pressure equal to the inside diameter of the discharge hose. Water volume/pressure drops off at the discharge hose as the standing water has been eliminated. The pump motor is still running and the discharge hose shows water being pumped out, albeit at a slower pace (most of the water in the tub is gone but for moisture in the wet laundry, which is being wrung out). The tub is spinning counter-clockwise at high speed, all is well down to 3, then 2 minutes left in the cycle. But, at around 1 minute, fresh water is let into the tub, in error, I think. While the pump does seem to be up to the task, at this point, the circuit has 1 minute or less to run and has not allocated, if you will, any more time to the cycle to spin and run the pump. It thinks it's finished and thinks there is no water remaining except for the damp clothes. I still think the problem is the introduction of additional water in the last minute of the Drain/Spin cycle when none should be allowed in.

I agree. Coupla thangs, tho...

Is water still in the drum at the end of the Rinse/Spin cycle, too?


7: Ran diagnostics; no apparent trouble codes (actually, put this back up towards top)


Did you run diagnostic test C:01?

Yes, water was still in the drum the last time I ran the Rinse/Spin cycle (or on any cycle we use). The Mrs. said yesterday it seemed like it drained the soapy water ok but left water in the drum during/after the spin cycle. I have been running the Drain/Spin cycle today, but will go back and make certain the Rinse/Spin cycle does the same thing. These are the shortest cycles I can think of; no point in runnin a full wash cycle to get to the same conclusion. As for the diagnostics, I ran the full set and it cycled through each one with no fault codes displayed. What am I looking for and is there a way to run just C:01?

Oh, forgot to mention...when running the diags (as shown in the tech bulletin inside the cabinet) when it finishes with C:08 and shuts down, it has removed the water from the drum normally, leaving just the wet (test) towels. Dunno if that's any help or not...

So, to summarize, we have water left in the drum at the end of the Drain/Spin and (we think, and will verify) the Rinse/Spin cycle, too.

If you run it empty, how much residual water is left in the drum?

I have been running the Drain/Spin cycle today, but will go back and make certain the Rinse/Spin cycle does the same thing.


Ver goot. Do dat thang.

Don't you have to push the Prewash button twice to advance to the next test? Here's the complete service manual. Test procedure on pg. 6-8 (pg. 52 in pdfville).

Was this towel wrung out properly? Did it come out dryer than a test towel run during either the Drain/Spin or the Rinse/Spin?

To answer your last reply; yes, it came out as it normally would...damp and ready for the dryer (which still works, thanks to you!) :-) On either the Rinse/Spin or Drain/Spin the towel(s) would come out sopping wet.

To answer this reply, yep, the Rinse/Spin cycle looks the same as the Drain/Spin cycle, that is, water is introduced late in the spin cycle (with approximately 1 minute left) and leaves a substantial amount of water in the drum on both cycles.

As for the diagnostic test, yes, you can push the PreWash button to advance through the tests but it will also cycle through them as each test is conducted. Will take a look at the test procedure in the manual and see what I get. Thanks!

You appear to be in the Eastern time zone while I'm in the Central. I appreciate your time and patience but you don't have to do this all night. :-)

Good morning, SAG! (Samurai Applicance Guru, but you knew that!)

After examining the manual (don't I owe you for that? I wuz gonna git one when I ordered whatever parts I will ultimately need), it appears that:

[align=left](from the service manual)[/align]
[align=left]There are two routes for the water to enter the wash tub.[/align]
[align=left]Most of the water flows through the dispenser assembly. A small portion of the water flow around the dispensers and is used to wash the door window.[/align]
[align=left]1. Main Inlet Tube (Fig. 3-5, A)[/align]
2. Window Washer Inlet Tube (Fig. 3-5, B)

Now, I may be overthinking this, but when the water is introduced during the last of the spin cycle, it enters through the Window Washer Inlet Tube only. None SEEMS to be coming in via the Main Inlet Tube.

Could this be a Dispenser/Dispenser Motor issue or...?

Nah, check that. Geez, haste makes waste!

What I thought was the Window Washer Inlet Tube is actually the Main Inlet Tube and what I thought was the Main Inlet Tube is actually the Vent Tube from the dispenser. Sigh. It's not like there weren't pictures!

Make sure the drain hose is not shoved real deep into the stand pipe, it's possible you are experiencing a siphon condition causing drain water to get sucked back into the machine.

You don't want an "air tight" connection at the drain either.

It's also possible your water fill valve is mechanically hanging up in the open position allowing too much water in during the rinse cycle.

Or, You have a coin lodged in the drain hose. Sometimes they get stuck in there and move around acting like a valve. It will drive you crazy. One time it works, next time it don't.

Thanks, Nick!

No, it's not air-tight but it's a good fit. No, I actually see water entering the tub at the last (inappropriate) moment with no time left to spin it out or run the pump. At that point in the Drain/Spin cycle, the pump is pretty much done.

How about the suggestion that, since we seem to NOT be using the correct (read HE) detergent, that a couple of hot cycles using common dishwashing detergent will 'clean' things out. Yes/no? Grasshoppah is sitting at the feet of the all-seeing, all-knowing Master. :-)

Sounds like a longshot to me but, if you've been using non-HE detergent in this washer, then you'll want to do some of the cleanout procedures discussed here:

Powder DW detergent is excellent for cleaning out front load washers, hot cycle with 1/2 cup to 1 cup of the powder works wonders....with nothing else in the washer..
