Just recently, my machine began kicking out "Ld" errors, and refusing to finish a complete cycle. Nothing has changed about the washer's position, drain hose height, etc. (It's been working fine in this location for about two years.)

The washer drains all of the visible water out of the tub quickly enough, and water rushes out of the drain hose, so I'm ruling out some kind of obstruction in the hose, or a total malfunction of the drain pump.

When it gives the error, I can pull all of the clothes out and run the "Drain and Spin" cycle with an empty tub, and it still gives the "Ld" error.

Just for fun, I ran the automatic diagnostics, and sure enough, it stalled out on step C7, draining. Again, all visible water drained out of the tub, and the pump kept running. I guess it would have run forever, if I hadn't shut it down, yes?

So I'm not sure what's up. Could it be some sort of weak pump, that's not pulling the last remaining water out of the machine? Or is there some sensor that could malfunction, and tell the washer there's water when there really isn't?

Any advice would be greatly appreciated!

Update: It seems to work again after sitting for several hours/overnight. Don't know if this modifies the diagnosis at all, but again (to me) seems to rule out some problem with the pump?

Thanks -- that's what I used to run the diagnostics. All the tests tell me is that, yes, the pump is going to run until kingdom come, and never evidently drain the tank to the sensor's satisfaction. (Even though I cannot see any water.)

Someone suggested that the pump was probably not dead, but going bad -- not draining within the given time parameters. Does this sound reasonable? I'd hate to drop $80-$90 on a new pump, and find out that's not the issue...

My new pump arrived today, and it seems to have done the trick! (So far, so good, at least...) Thanks for the help!

Boy, hard to say since this model has some pretty complex (and somewhat useless) electronics.

Generally the main control board is the weak point in these models, but I cannot think why it would act one with a small load and another way empty. However, that is the mystery of electronics.

Anyway, see if you can check out the board.

Problem:
I have a Whirlpool Cabrio Washer WTW6200SW0 that kept showing the common Long Drain problem "LD". I did all of the things suggested on fix-it sites and forums like this. I had in pieces many times but I never found the true cause until today. It would do it usually twice during the cycle, once at 23 minutes left, and one at 8 minutes left. It would not start the spin cycle - clothes still very wet, but not much water left in the tub. It pumped water out fine.

Unplugged and left to sit anywhere from 5 minutes to overnight, it would restart OK and complete a cycle. I lived with this frustrating mode for months.

Fix:
The pressure transducer needed calibration. The maintenance documents were taped inside the front panel. You can find them after opening the "hood". They are not the easiest to read/follow but "TEST#6 - Water Level and Pressure Transducer Calibration" was what will fix this. It is a series of button pushes on the user interface, not laborious at all, that will re-calibrate the pressure sensor to your current pressure for empty/full. The procedure is in the service technician maintenance document Part #8567037 Rev A.

I hope this helps someone else out, or saves them from buying a new motor/control unit (which would mask the un-calibration of the original unit). :)
