How to fix the PE error code in an LG washer dryer combo unit

Posted by Samurai Appliance Repair Man, in Washing Machine Repair, Dryer Repair 06 November 2013 · 1,947 views
LG, washer, dryer, combo and 3 more...

"PE" error:

Water Level Pressure Sensor Error.


1) Verify that the black tube is still connected to the Water Level Sensor at the top of the washer---and to the Air Bell at the bottom of the tub.

2) Remove the black tube from the Water Level Sensor---and blow into tube---to clear a possible blockage. Reconnect and test washer.

3) Water Level Pressure Sensors (6601ER1006E) *rarely* fail.

Dryer Auto Dry cycle not working - a simple fix using the Dean's Method

Posted by Samurai Appliance Repair Man, in Dryer Repair 06 September 2013 · 1,703 views
dryer, auto dry, moisture sensor
Most dryers have an Auto Dry cycle where it sense the dryness of the clothes and adjusts the cycle time accordingly. Sometimes, clothes will stop drying properly on the Auto Dry cycle but still dry normally on the Timed Dry cycle. Brother john63, the Dean of LG Appliantology, has developed a simple procedure to correct this problem and it works on all brands and models of dryers with an Auto Dry feature.

Reading material:)...


The complaint was identical:

"Laundry doesn't always dry" (and the vent system was ruled-out)

The responses were similar:

"Avoid small loads in dryers that have/use MOISTURE SENSORS"

or...

"For small loads---use the TIME DRY cycle"




There is a solution---and it's a very simple one.

Some years back---I had an older lady (widow)---that contacted us regarding her LG dryer.
Her complaint was that the laundry was not dry at the end of the cycle.
Also---the cycle run time/duration was rather short (cycle ended far earlier than initial time displayed).

In her case---she does not wash/dry large loads at all---and rarely does she even have medium sized loads to wash.

On LG dryers---the MOISTURE SENSOR ("bars") are located at the front of the dryer---on the LINT FILTER HOUSING.

If the dryer is dead-level---which hers was---a small load of laundry will tumble in the GIANT DRUM and very erratically come into contact with the MOISTURE SENSOR.

By raising the REAR LEVELING LEGS about an inch---this forced the tumbling small load of laundry to remain at the *front* of the dryer---continually falling/contacting the MOISTURE SENSOR.

On dryers (other brands) in which the sensors are positioned at the rear/back of the drum---simply raise the *front* leveling legs to get the same result.

Technicians can demonstrate to the customer by running the dryer with 2 or 3 small pieces of clothing---laundry will either tumble at the rear of the drum or near the center (in an LG dryer--for example).

Explain to the customer---the MOISTURE SENSORs function and that wet/damp laundry *must* continually come into contact with the sensor (show the customer the location of the sensor).

After adjusting the legs---the customer/owner will notice the laundry moving toward the SENSOR location within 30 seconds of starting the cycle---and remain at that location in the drum for the duration of the cycle.

Dry laundry.

Tips for getting the best results from your LG washer-dryer combo

LG, washer, dryer, combo
Brother john63, the Dean of LG Appliantology, offers some pearls of wisdom for getting the best results from those LG washer-dryer combo units:

Provide your customer with the following information---and they'll be more informed as to how best to use the combo washer/dryer.

Use ONLY "HE" type detergent in the following dosage (for this small-size tub):

HE (regular concentration): (1) Tablespoon Per Wash

HE 2X (double concentrated): (1) Teaspoon Per Wash

HE 3X (triple concentrated): ***NOT RECOMMENDED***

Remind the customer *not* to load the washer tub past the ***black hash mark*** that is located on a sticker/emblem---on the left side of the door/tub opening.
A fully loaded tub will *wash* fine---as long as the clothing is not compressed/pushed into the tub but---the laundry will not dry very well (taking up to 6 hours to dry laundry).

Advise the customer to select/use the TIME DRY dryer cycle rather than *automatic*.
They will need to select the desired cycle RUN TIME for the dry cycle.
After a month or so of using the TIME DRY cycle---the customer will become familiar with the amount of time needed to adequately dry an average-size or type of laundry load.
Using the TIME DRY cycle in a combo unit---eliminates/avoids using the dual THERMISTORS that are located on the DUCT ASSY.
This also allows for a higher temperature during the dry cycle (laundry dries faster).
Use the *automatic* dryer cycles for Delicates only.

Armed with all of this *very* relevant information---the customer becomes less frustrated/more relieved---that not only do they have far better *intel* on their particular combo---but that you ACTUALLY CARED to inform/educate them about it.
It's best to write this down and give it to the customer.
It's *impossible* for the average customer to *memorize* all of this:)
Good Luck.

LG WM3677HW Combo Washer/dryer - washes okay but doesn't dry

Posted by Samurai Appliance Repair Man, in Dryer Repair, Washing Machine Repair 07 August 2013 · 1,415 views
LG, washer-dryer, combo
One common problem with these combo laundry units is that they'll stop drying the clothes. The dryer portion of the combo unit is a condenser type dryer. It works on the principal that water condenses on a cool surface, similar to moisture collecting on a cold drink on a hot and humid summer day. A fan circulates air through the warming duct, drum, and condenser and over and over. The air is warmed because warmer air holds more moisture than cooler air and the heat causes more of the water to be evaporated form the laundry. The warm, moist air is directed through the condensing duct, which is cooled by a spray of cold water. This difference in temperature causes the moisture to precipitate in the condenser, where it and the cooling water are exhausted by the drain pump. The air, now dry, is passed over the warming element and through the laundry again as the process repeats itself. Because the air is recycled instead of exhausted, a vent and lint filter are not necessary for this type dryer.

If you don't work on a lot of these units, they can be strange and mysterious beasts, even leading some techs to go insane on blind, parts-changing rampages in a vain attempt to fix a no-drying complaint.

Brethren, let us unbunch our panties and unfurl our brows while Brother john63, Dean of LG Laundry Appliantology, reveals to us the solution which, like most technical solutions, is stunningly simple once you hear it, yet ever elusive to the uninitiated:

Plan of attack as follows...

1) Remove the DUCT from the tub. Pay particular attention to the area of the duct---where it connects
to the bottom of the tub. Clean the duct system thoroughly.

2) Replace the DRAIN MOTOR (4681EA2001T)

3) Verify that the COLD WATER VALVE ASSY is the ***correct*** one. If not---replace it (5220FR2008E)

Repeat the above steps---every 3 years.

Laundry can be loaded into the tub---3/4s full.

When the laundry becomes wet during the *wash* cycle---the laundry will *sag* within the tub---to approximately 1/2 or less of the tub opening.

This will permit faster drying---than an overloaded combo unit.

from the Tech Sheet - 3977696

Thermistor Test or Dryer Beeps 3 Times When PTS Pressed
An electronic temperature sensor called a thermistor is used in this model in place of an operating thermostat.
The Even Heat control monitors the exhaust temperature using the thermistor and cycles the heater relay on and off to maintain the desired temperature.
Procedure
Begin with an empty dryer and a clean lint screen.
1. Set the following configuration:
Timer Dial - TIMED DRY
Fabric Care/Temperature switch - COTTON HIGH
Signal switch - LOUD
Door - must be closed
2. Press the Push To Start switch.
a. If you hear three short beeps and the dryer shuts off after several seconds,
the thermistor or wire harness is either shorted or open.
Check wire connections at Even Heat control and thermistor.
If wiring is functional, replace the thermistor:
b. If the dryer appears to operate correctly, proceed to step 3.
3. Remove exhaust vent and start the dryer.
a. Turn Fabric Care/Temperature switch to desired temperature to be tested,
and select 20 minutes on the TimedDry dial.
Hold a glass bulb thermometer capable of reading from 90°F to 180°F in the center of the exhaust outlet.
Measure exhaust temperatures with heater off and on.
The correct exhaust temperatures are as follows:
FABRIC CARE/TEMP.
SWITCH SETTING . . . . HEAT TURNS OFF. . . . . . . . HEAT TURNS ON

COTTON . . .. . . . . . . . 150°F . . . . . . . . . 10° - 15°F below heat off
NORMAL/PERM PRESS 140°F . . . . . . . . . . 10° - 15°F below heat off
KNIT/CASUAL . . . . . . . 125°F . . . . . . . . . . 10° - 15°F below heat off
ULTRA DELICATE . . . . . 115°F . . . . . . . . . .10° - 15°F below heat off
b. If the exhaust temperature is not within specified limits, check the resistance of the thermistor.
THERMISTOR RESISTANCE
TEMP ° F . . . . . RES. K . . . . . TEMP. ° F . . . . . RES. K
50° 19.9 100° 5.7
60° 15.3 110° 4.7
70° 11.9 120° 3.7
80° 9.2 130° 3.1
90° 7.4 140° 2.5
c. If the thermistor resistance checks within normal limits, replace the Even Heat control.
