How to fix an E1 error code in a Whirlpool Duet GEW9200 washer

Posted by Samurai Appliance Repair Man , in Washing Machine Repair 10 October 2011 · 4,559 views
E1, Whirlpool, washer, Duet
Chief ReliableApp guides us through:

The thermistor is directly related to E1 error code. There are different resistance levels at different temperatures. I would try this thermistor test and more than likely I would replace the thermistor

The machine control electronics monitors the
exhaust temperature using the thermistor, and
cycles the heater relay on and off to maintain
the desired temperature.
Begin with an empty dryer and a clean lint
1. Plug in dryer or reconnect power.
2. Set the following configuration:
➔ Door – must be firmly closed
➔ Press Control On
➔ Press End Of Cycle Signal (Louder)
➔ Press Start
3. If after 60 seconds, E1 or E2 flashes in the
display and the dryer shuts off, the thermistor
or wire harness is either shorted or open.
➔ Unplug dryer or disconnect power.
➔ Check wire connections at the machine
control electronics and thermistor. See
Accessing & Removing the Electronic
Assemblies, page 7, and figure 8 for
thermistor location.
➔ If wire connections are good, remove the
two wires from the thermistor and replace
the thermistor

And Sublime Master KurtiusInterupptus offers this caveat:

Just because the thermistor checks good @ room temp doesnt. Mean it stays within tolerance as it heats up...

replace it.

How to check the motor on a Maytag Neptune MAH5500BWW washer

Posted by Samurai Appliance Repair Man , in Washing Machine Repair 09 October 2011 · 2,195 views

Grand Master RegUS_PatOff tiptoes us through these tulips:

Motor Windings Check

1 . Disconnect power to the unit.
2 . Remove each pair of phase wires from the motor control and perform an ohm check of each wire leading to the motor.
Each wire pair should show 2-3 ohms resistance.
2 . There should be no continuity between any of the terminals and the frame of the motor.
3 . Check that all six motor terminals are secure and at the same height in the connector housing.
Replace motor if terminals are pressed into the motor.
4. Remount the six-position motor connector onto the motor.
Reassemble the drip shield cover onto the motor control.
5 . Reposition the motor control into the washer when finished.
Make sure the two screws and the twistlock wire ties are fastened properly to the wire harness.

How to test the heating element in a Bosch SHE43C02UC dishwasher

Posted by Samurai Appliance Repair Man , in Dishwasher Repair 08 October 2011 · 3,788 views
Bosch, dishwasher, heater
Sublime Master KurtiusInterupptus waxes eloquently:

Wanna make damn sure before you try go expose that element...a real bitch to get at.

do you have an amp clamp? If so here is my method to test this ...
remove the door panel outer..
clamp amp clamp around red wire in the harness..
start a cycle, follow the red wire up to the controller and then take a small jumper wire and jump between the red and black wire in the back of that plug.
does the amp meter show a current of 8-10 amps? If so, the heater and high limit are good and prolly just a bad controller.

Probably about the easiest job you can do.

1) Unplug washer
2) Remove one screw at each end of the top console, (looks like they will be in front on your model, if not in front look in back).
3) Push timer knob in for off and turn it counter clockwise to unscrew the knob from the timer and pull the dial skirt off.
4) Remove the one or two 5/16" screws that you will find under the timer dial skirt and timer will drop down into console.
5) flip console up and unplug connector from timer
6) Install new timer and reverse procedure to close back up.

How to fix a Samsung DMR57 or DMR78 dishwasher making a grinding noise and error code 9E

Posted by Samurai Appliance Repair Man , in Dishwasher Repair 05 October 2011 · 5,029 views
Samsung, dishwasher, 9E and 1 more...
Sublime Master john63 reveals the kata for this encounter:

<<<There is a grinding noise when first started up>>>


Many Samsung DMR57 & DMR78 dishwashers are known for developing a rattling/grinding noise during DRAIN MODE.

This is usually caused by a broken plastic mounting tab from the upper rack ADJUSTERS.

Each side of the upper rack has a tan/gray square RACK ADJUSTER---after a mounting tab (or 2) breaks off---this piece of plastic eventually ends up in the DRAIN PUMP HOUSING.

The DRAIN MOTOR should be removed to inspect for debris.


<<<after a minute or two I get 9e error code>>>


A normal amount of water in a DMR78 dishwasher would be---at about 1 inch past the HEATER SHIELD in the tub.

If you've tested the SWITCHES on the LOW LEVEL SENSOR---then they're not at fault.

Press the following buttons at the *same* time:


The word "ALL" appears for 3 seconds followed by "t1"

(NOTE: Test #1 checks the functions of the INLET VALVE--FLOW METER--LOW LEVEL SENSOR)

Press the DELAY START button---the DRAIN MOTOR will run for 45 seconds. Then---water will enter the tub.

When the PULSE COUNT (on the display) reaches "660" or greater---press the NORMAL button four times.

A flashing "t5" will be displayed & water will drain for 30 seconds. After 30 seconds---the "t5" will stop flashing.

Press the NORMAL button again---"t6" will be displayed. The word "OFF" should appear in the control panel display---indicating that the LOW LEVEL SENSOR SWITCH is in the correct position for *No Water* in tub.

If the INLET VALVE--LOW LEVEL SENSOR--FLOW METER function normally----replace the MAIN BOARD.
