LG WM2688 Tub Clean doesn't work

i think you model has a tub clean mode. i would try to do that. basically no clothes, no detergent, just fill the bleach dispenser and run the tub clean mode. press power and then hold in the tub clean button on the right for 3 secs. then press start.

Read these instructions carefully before
beginning the TUB CLEAN cycle.
1
Open the door and remove any clothing in
the wash drum.
2
Open the dispenser drawer.
3
Add liquid chlorine bleach or tub cleaner.
Some powder or tablet tub cleaners which
are manufactured for this purpose can be
used.
(NOTE : Do not add any laundry detergent
or fabric softener to the drawer when using
TUB CLEAN.)
- If using liquid chlorine bleach
Add liquid chlorine bleach to the bleach
compartment of the drawer.
(NOTE : Do not exceed the maximum
fill line and do not pour undiluted liquid
bleach directly into the wash drum.)
- If using powder cleaner
Remove the liquid detergent cup and
add powder cleaner to the main wash
compartment of the drawer.
- If using tablet cleaner
Add tablet cleaner to the wash drum
directly.
(NOTE : Do not add tablet cleaner to the
drawer.)
4
Close the drawer and washer door.
5
Select TUB CLEAN and press START.
NOTE : It is recommended that TUB CLEAN
should be repeated monthly.
If mildew or musty smell already exists, run TUB
CLEAN for 3 consecutive weeks.
After TUB CLEAN is complete or when the washer
is not used, leave the washer door open for better
ventilation and drying inside of the washer

If the model number is correct, to run a "Clean" cycle on this model washer you need to follow these steps:

1. Make sure wash tub is empty and close the door.

2. Open the dispenser drawer and remove the plastic divider in the MAIN DETERGENT compartment.

3. Select the following options:

a. Select the POWER button.
b. Select RINSE/SPIN.
c. Select LOW SPEED SPIN.
d. Select WARM/COLD water temperature.
e. Select END OF CYCLE SIGNAL to SOFTER.
f. Press EXTRA RINSE button 4 times within 5 seconds and the
will begin.

4. The washer will run a short sensing cycle for about 3 minutes.

5. The washer will beep 4 times and a code will appear on the front panel display.

a. If "Ab" (Add Bleach) appears - skip to step 6.
b. If "Rl" (Remove Load) appears - the door will unlock and you
need to double check the wash tub for any items. Close the
door when complete and press the START button.

6. Add bleach. If this is the first time running the clean cycle add ONE CUP of bleach to the detergent compartment of the dispenser drawer. If this is a monthly routine, add only 1/3 CUP of bleach.

I just called LG and they said for this model WM2101HW the bleach will only dispense from the soap dispenser during the tub clean cycle

Regular cleaning maintenance is required to prevent odor build up inside the machine. The LG WM2688HWM has a TUB CLEAN feature, a special cycle for the cleaning of the inside of the washer. This cycle uses a high water level with higher spin speed.

1. Remove any clothing or items from the washer and close the door.
2. Open the dispenser drawer and add liquid chlorine bleach ONLY to the bleach compartment.
3. Close the dispenser drawer slowly to prevent the bleach from spilling.
4. Turn on the machine then press the EXTRA RINSE button for 3 seconds.
5. Press the START/PAUSE button to start.
6. Leave the door open to dry the washer door opening, door seal and door glass after the cycle is complete.

Try using the tub clean cycle and use a good dose of bleach or vinegear. Here is how to run the tub clean cycle.

• To start the TUB CLEAN cycle:
1. Remove any clothing or items from the washer and close the door.
2. Open the dispenser drawer and add liquid chlorine bleach to the bleach compartment.
NOTE: Do not add any detergent to the detergent compartments. Excessive suds may be produced and leak
from the washer.
3. Close the dispenser drawer slowly.
4. Power On and then press the Extra Rinse button for 3 seconds. (Prewash option will be selected.)
5. Press the Start/Pause button to start.
6. After the cycle is complete, leave the door open to dry around the washer door opening, door seal and
door glass.

Push and hold Stain Cycle button for 3 seconds to cancel spinsense. Then, turn off machine. When you power it back on, press "Extra Rinse" for 3 seconds and push the START button.

When cleaning tub, do NOT use detergent--only use liquid chlorine bleach.

You need to turn "off" the "spinsense" feature before you can successfully activate the 'tub clean' cycle.LG won't tell you this.Just make sure you turn it back "on" after you are done,as you probably turned it on for a good reason.

Actually, that is not an error code. It is telling you to add bleach to the dispenser for the tub clean feature.

All you need to do is add bleach at this point (or Whirlout which works even better). Make sure you do not have any clothes in the machine when doing the tub clean cycle.

Hope this helps, please rate my answer.

Thanks to a couple of previous responders, 6 months of frustration has now ended - I can now run the Tub Clean on my LG Steam Washer! I first want to say that it is important not to get excited and start pushing buttons randomly, as I think I had been doing for all these months when I couldn't get Tub Clean to work by pushing the button in for 3 seconds. Just do the following, which combines and expands on a couple of previous responses:

1. I had to deactivate the Spin Sense, and if your Spin Sense is ON, you will have to do this too. (It is ON if the spin speed light flashes while any of the wash cycles is in progress. If spin speed button does not flash while a wash cycle is in progress, the Spin Sense is already off.) So how to deactivate Spin Sense? Select Speed Wash, and start the cycle. Let it run for about 20 seconds and THEN push and HOLD IN in the Spin Sense option button for 3 seconds. The blinking spin speed button will stop blinking and you will then know that the Spin Sense is OFF.

2. Once Spin Sense is off: Start with your machine turned off. Then push the power button on and select the RINSE AND SPIN option button. Then START the Rinse and Spin cycle. Let it run for about 5 seconds and then PUSH IN AND HOLD THE TUB CLEAN OPTION BUTTON FOR 3 SECONDS. You will then see the little LED light panel show something that looks like tcl. And you are there! Just leave it alone .... the LED will change to one hour and 25 minutes. And it will clean your machine just great.

3. Don't forget to put your bleach in the detergent cup before you start all of this.

I want to thank the two responders above who gave me the essential features for this fix. I forgot to make a note of their names before I started this response, but you can see who they are. I am so excited. Now EVERYTHING works on my LG Steam Washing Machine. I love this machine. It is a miracle of cleaning, especially since I own 4 large breed dogs and am washing and sanitizing large hairy and smelly bedding each and every day. And I no longer have to iron anything - I just use the steam cycle to unwrinkle our clothes. Best washer I have ever owned (and I have owned another major brand of large capacity front loading washer before - no comparison).
