Some of my notes:
When you press the "SPIN SPEED" button and "SOIL LEVEL" button the water level frequency should be above 246. If it be below that number find the small tube going to the control and blow it out. Get rid of the sediment in the air bell and reconnect tightly. Pump out water and retry.
Hall sensor failure:
When too much of the low-sudsing HE detergent is used in the LG washers (and especially non-HE type detergent)...
The motor & main board will detect suds when the tub begins to spin.
As strange as this sounds--suds causes drag/resistance.
The older hall sensors overheated--the main board would shut-down the washer & flash an error message of "LE".
If the Hall Sensor was not damaged--then the customer would be able to unplug the washer for about 2-3 minutes and plug in the washer again--the washer would be able to be re-started (reboot of the computer).
Eventually--this results in an "LE" error that won't re-set and the Hall Sensor needs to be replaced. The tell-tale symptom of this (aside from a "stuck" LE error) is that when the customer pushes the START button--the tub *wiggles* momentarily before flashing LE again.
On a few occasions--the washer WILL start but the motor GROWLS loudly.
It's very important not only to use "HE" (High Efficiency-Low Suds) type detergent--but to use the correct amount.
Nearly all brands of "HE" detergent have incorrect dosage 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 usage.
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.LG washer repair manual
