Have an LG WM2455HW washer purchased about 3 months ago. It seems to be overly sensitive to suds. It rarely completes a cycle normally without going into the "suds removal program." It’ll stop before the wash cycle completes, drain, sit there idle for 5 minutes, and then jump ahead to the rinse cycle. There is not any excessive sudsing in the machine when this happens (in fact, hardly any sudsing at all). Being an engineer I need to know why (and how) this happens. I popped the cover and took a look under the hood. There are only 3 methods the main board is getting feedback from the washer: a thermistor to sense tub water temperature, a pressure switch to sense tub water level, and the Hall Effect sensor on the motor to sense rotational speed. How does it determine there is too much sudsing? Another factor: There are 2 "ports" on the top of the tub, one where the water flows in and one connected to the vent on the back of the machine. Inside each of these is what I would call a "mushroom valve" that acts like a check valve. Could it be that suds build up between the inner and outer tubs (unseen to me) forcing these valves shut, then pressure builds up in the tub, and the pressure switch interprets this as an over-suds condition? That’s the best theory I can come up with. Perhaps the assembled brain trust here can shed some light on this and provide a possible solution.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

Have you changed your door latch wax motor yet... If you have the brown actuator pin then you want to chuck that wax motor out of there quicker than spit! You want the redesigned wax motor with the black actuator pin. I know of folks where the wax motor failure caused the timer and /or water valves to act up... See www.neptunewaxmotor.com for disassembly photos and other Neptune information.

The tub was slipping on the motor and when loaded would not spin. I noted when accessing through the back panel that the rotor bolt was loose, probably from the factory as the unit has been used less than two years. When I inspected the rotor, the plastic insert that is screwed into the rotor housing and provides the splined hole that fits over the splined shaft from the motor/stator, the plastic ridges had been destroyed. There are three screws mounting the plastic piece onto the rotor so it appears that the designers anticipated selling replacement for the plastic piece alone. So far this evening, I've only been able to find complete rotor assemblies costing $100+. So, bottom line, your rotor may just be loose.
error can sometimes present because of a miscommunication between the
control panel and the wash motor. In this instance, the washer simply
needs to be reset.
Step 1: Unplug the washing machine. Step 2: While the washer remains unplugged, press and hold the [Start/Pause] button on the front panel for 5 seconds. Step 3: Plug the unit back in, and run a rinse and spin cycle to test if the LE code is cleared.
Are there soap suds visible in the drum? Over-sudsing
is the main cause of LE error codes. Using non-HE (high efficiency)
detergents or too much detergent will cause stress on the motor. In
addition, detergent residue can also cause leaking and odor. Follow
these steps to resolved an LE error code caused by over-sudsing.
Step 1: Unplug the washer and allow the unit to sit for 30 minutes to give the suds time to dissolve. Step 2: Plug the washer back in and press [Power] to turn on the washer. Step 3: Do not choose a washing cycle. Press the [Spin Speed] key until "No Spin" is selected. Step 4: Press [Start/Pause] to begin a drain only cycle. Step
5: After the drain only cycle has completed, remove the clothing items
from the machine. Turn the power back on and select [Rinse and Spin] and
then press [Start/Pause]. This will remove excess soap suds and light
residue from the drum. Repeat this step until no visible suds are in the
drum of the washer.

SUD means a detection of suds in the machine. These machines are very sensitive to over sudsing. Try adding just plain water or bleach to break down the suds level. They say to use 1/4 of the detergent you would use in an older machine.
If you see "Sud" or "Sd" with the Rinse status light on, the washer is in the process of removing suds. Let the cycle finish
If you see "Sud" or "Sd" and the Cycle Complete light is on, the washer
detected too many suds during the cycle and your load may not be fully
rinsed or water may not be fully removed. You may want to select a
Rinse/Spin cycle for further rinsing.
Are you using the correct amount of the correct soap? These machines struggle with soap overdose. My notes: You MUST use "HE" (High Efficiency-Low Suds) type detergent--but to use the correct amount. Nearly all brands of "HE" detergent have incorrect instructions.
The correct amount is as follows:
HE: (2) Tablespoons Per Washload
HE 2X (double concentrated) : (1) Tablespoon
HE 3X (triple concentrated): (1) Teaspoon
1) Musty Odor
2) "LE" Error/Interrupted Cycle
3) L-O-N-G Cycle Times (longer than time displayed)
4) Insufficient Cleaning Results
5) Small Water Leaks from the air vent behind the washer or at the front door gasket
6) Damaged Hall Effect Sensor (on 2007 or older LG washers)
7) Reduced Spin Speeds (laundry not spin-dried effectively)
Most consumers were doing what is *normally* the right thing to do, which is to follow directions on the detergent label. In this rare case--those directions should be entirely disregarded.
Additionally--in many LG washers--the liquid dispenser cup (blue cup) has a "MAX" line on the white siphon cap. This was a very big *faux pas* on LGs part--this "MAX" line has NOTHING to do with measuring detergent and should never be used as a guide for determining correct detergent amount. The "MAX" line indicates how much liquid must be in the blue dispenser cup before it DISPENSES from the bottom of the cup. This is a very,very frustrating mistake that gives owners much grief.
After three months of incorrect type of detergent or incorrect amount of the correct detergent used--musty odor begins to occur. After more than two years--a significant amount of soap scum/curd has accumulated in the washer. Odor-causing bacteria flourishes on this build-up. It is imperative to remove this slimy residue. Tide sells a product called "TIDE WASHING MACHINE CLEANER" which is very effective.
Once a tub has become heavily contaminated--normal methods of performing a TUB CLEAN cycle won't "cut it".
Add the entire packet of "TIDE WASHING MACHINE CLEANER" directly into the tub (no laundry) and close the door.
Press and hold: SPIN SPEED & SOIL LEVEL buttons--then press POWER button. Wait for door to lock.
Press the START button (6) times--this will fill the tub with hot water to the maximum setting when it stops filling.
Press the START button two more times--this will enable the tub to tumble. After 3 hours--turn "off" the washer. Turn the washer back "on". Select the shortest wash cycle (usually "quick wash") and press "START". This will rinse out the tub. This method of "TUB CLEAN" is *not* from a service manual but has been the best method for cleaning out LG washers more than a year into incorrect detergent useage.
After this--use the correct amount of "HE" detergent & perform a "TUB CLEAN" cycle every (4) months using the *tub clean* option on the control panel.
Most digital-controlled front load washers have a software feature that consumers are unaware of. If excess suds is detected by the MAIN BOARD (which monitors motor electrical load during rinse & final spin) the "suds kill mode" will be enabled. This causes the washer DISPLAY CLOCK to stall. The washer makes an attempt to reduce/remove suds--usually a futile attempt--and ends the cycle much longer than was originally shown on the DISPLAY.
are you using he detergent,,,or low suddsing detergent,,,i believe your putting to much detergent,,and not the right detergent,,,to test run a load with no soap,,and see if you get water on the floor..onthejob
have you tried adjusting the feet on the front of the washer so it is tilted back slightly .This will stop the water from coming over the little lip on the front of the machine. Some dishwashers also use a little amount of water in the bottom when drying asthis helps to curculate the heat ; leave the washer to complete it's cycle and it should beep to let you know when it is finished
i used to do warranty work for LG needless to say, after finding out customers were waiting up to 2 1/2 months just to get parts i stopped doing any work for them. if it were me, i would take both the washer and dryer back and buy a bosch instead. much more reliable and there customer service is great
