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.

Posted by Samurai Appliance Repair Man, in Washing Machine Repair 06 November 2013 · 1,051 views
LG, washer, power, display and 1 more...

Remove the Top Cover of the washer.

Trace/follow the *plug* inside the washer---to the Electrical Noise Filter (6201EC1006L)

Pull off the *white* plug---use a test meter to check for 120V at the *white* plug (if no power---the fault is outside of the washer)

Re-connect the *white* plug back into the Noise Filter

Pull off the *pink* plug from the Noise Filter---test for 120V at the **Noise Filter** (NOT at the pink plug)

If no 120V at the Noise Filter---replace it.

If 120V is measured at the Noise Filter---replace the Main Board (EBR64144911)

Troubleshooting a Whirlpool Duet Washer with an F11 error code and repairing it without replacing parts

Posted by Samurai Appliance Repair Man, in Washing Machine Repair 23 October 2013 · 1,847 views
Whirlpool, Duet, washer, F11 and 4 more...
Many appliance servicers have been befuddled by the elusive and mysterious F11 error code in these Whirlpool Duet front loading washers (also sold under the Kenmore brand). In their confusion and frustration, many will go into Parts Changing Monkey mode and start blindly replacing expensive control boards without really fixing the problem (but still charging the customer, of course).

The Appliance Guru never does business that way. Customers hire me to solve a problem. Period. I give a quote up-front for the complete repair cost and I stick to it. If my diagnosis is wrong, that's my problem, not the customer's and it won't cost them a penny more than what I quoted.

How can I offer professional appliance repair services this way and stay in business? Well, it means I better know what I'm doing and be able to do real troubleshooting, not just throw parts at the problem and hope to get lucky.

The infamous and all-too-common F11 error code in these Whirlpool Duet front load washers is a case-in-point. The tech sheet inside the washer says this is a communications error between two control boards: the CCU (central control unit) and MCU (motor control unit). Even Whirlpool's own technical guidance for this error is abysmal; they say to replace the CCU and if that doesn't fix it, then replace the MCU. This is why there is so much confusion among appliance repair techs in the field. Each of these control boards costs well north of $200 and the CCU in particular goes on frequent backorder, adding lots more cost and inconvenient downtime to the customer.

As I show in the video, the F11 error code problem in these Whirlpool Duet washers can almost always be repaired without replacing any expensive control boards. It's at least an easy and inexpensive repair to try before replacing the CCU or the MCU.




Understanding how the Water Level Sensor in LG Washing Machines work

Posted by Samurai Appliance Repair Man, in Washing Machine Repair 19 October 2013 · 2,273 views
LG, washer, water level sensor and 1 more...
Water level sensing in LG washers is done differently from how you may be used to seeing it done in other brands. Whirlpool, GE, Electrolux and others use an air tube connecting an air dome on the tub to a pressure sensor with a physical diaphragm or transducer that "feels" the water level increase as an increase in pressure inside the air tube. LG uses frequency measurements. How's that again? I'll let Brother john63, Dean of LG Appliantology explain:

The Water Level Frequency Sensor operation is based on the displacement of the *coil* attached to the diaphragm.

When the *coil* raises or lowers---it changes the electronically resonant characteristics of the oscillator circuit.

The water level is measured by the Main Board---by frequency readings.

I've never had a failed Water Level Sensor.

It is best tested while on the washer---by using the TEST MODE.

On most LG washers---the Test Mode is enabled by pressing and holding the SPIN SPEED and SOIL LEVEL buttons---and then pressing the POWER button (release all 3 buttons and wait for the door to lock).

Press the START / PAUSE button 4 times at one second intervals (Prewash Cold Water Fill)

The display read-out on the Control Panel will show the *frequency*

Empty---the frequency read-out should be about 255

A tub full of water should show a frequency of about 214 (depending on model number)


Some of the errors that can be displayed---relating to water fill are...

IE error:

Little or no water---usually caused by a failed Water Valve

FE error:

Too much water (overflow detected)---Can be a failed/stuck open Water Valve or blockage in the black air tube which is connected to the Water Level Frequency Sensor. Disconnect the tube from the sensor---and blow air back into the tub to clear obstruction.

To test the Water Level Frequency Sensor outside of the washer...

Use a test meter to check the ohms between pins 1 and 3 (should have between 21 & 23 ohms).
