Whirlpool Dryer Various Test Procedures - Part 3

TEST #5 Moisture Sensor
NOTE: This test is started with the machine completely assembled.This test is performed when an automatic cycle
stops too soon, or runs much longer than expected. NOTE: Dryer will shut down automatically after 2-1/2 hours.
The following items are part of this system: Harness/connection, Metal sensor strips, Machine control electronics
1. Activate the diagnostic test mode and advance past saved fault codes.
2. Open the dryer door. If a continuous beep tone is heard and an alphanumeric number is displayed on the console as soon as the door is opened, a short circuit exists in the moisture sensor system. If this doesn’t happen, go to step 3. Otherwise, go to step 4. NOTE: Over drying may be caused by a short circuit in the sensor system.
3. Locate the two metal sensor strips on the inside of the dryer. Bridge these strips with a wet cloth or finger.
If a continuous beep tone is heard and a software revision number is displayed on the console, the sensor passes the test. Go to step 8. If not, continue with step 4.
4. Access the moisture sensor wires: Remove the lint screen. Remove the two wires holding the lint screen to the top. Remove the four screws from bottom of the duct in rear. Remove the duct from the dryer to access
the moisture sensor.Disconnect the sensor connector.
5. Access the machine control electronics. Remove the connector P13 from the circuit board. Check the main
harness connections between the sensor connector and machine control for a short or open circuit. Replace the main harness if necessary. If the harness is okay, continue with step 6.
6. Measure the resistance across the outermost contacts of the sensor connector that includes the two MOVs. Sensor Harness with MOVs (Metal Oxide Varistors) Sensor Connector Sensor Blower Housing Disconnect sensor connector. If a small resistance is measured, check for debris across moisture strips inside of the drum; clean if debris is present. If debris is not present, replace sensor harness with MOVs. Otherwise go to step 7.
7. Measure the resistance across each of the outermost contacts and the center terminal (ground connection).
If a resistance less than infinity is measured, replace the sensor harness with MOVs.
8. If moisture sensor diagnostic test passes, check the thermistor: Perform TEST #4a. If the problem persists after replacing the moisture sensor, harness with MOVs and thermistor, replace the machine control electronics.

TEST #6 Buttons and Indicators
This test is performed when any of the following situations occurs during the Console Buttons and Indicators Diagnostic Test:
None of the indicators light up No beep sound is heard
Some buttons do not light indicators None of the indicators light up:

1. See Diagnostic Guide/Before Servicing.
2. Perform TEST #1 to verify supply connections.
3. Perform TEST #2.
4. Visually check that the P5 connector is inserted all the way into the machine control electronics.
5. Visually check the user interface assembly connections.
6. If both visual checks pass, replace the user interface assembly.
7. Plug in dryer or reconnect power.
8. Perform the Console Buttons and Indicators Diagnostic test to verify repair.
9. If indicators still do not light, the machine control electronics has failed: Unplug dryer or disconnect power.
Replace the machine control electronics. Plug in dryer or reconnect power. Perform the Console Buttons and Indicators Diagnostic test to verify repair.

2. Plug in dryer or reconnect power.
3. Perform the Console Buttons and Indicators Diagnostics test to verify repair.

TEST #7 Door Switch
Activate the diagnostic test mode and perform the Door Switch Diagnostic test.
Functionality is verified with a beep each time the door is closed and opened, and a number and letter appears in the display (i.e., 0E, 09). If any of the above conditions are not met: Unplug dryer or disconnect power.
Check that the wires between the door switch and machine control electronics are connected. If the connections are OK, replace the door switch assembly and retest. If the door switch assembly has been replaced and dryer still does not start, replace the machine control electronics.

Washer error on rinse cycle


E11 means the Fill time is too long. There are a whole bunch of tests to perform - but the easiest is to replace the hoses going into the machine - I had the same problem and tested my hoses - they looked fine - but my machine would do this every so often - turns out my hoses had "check valves" that were a safety design to prevent freeflowing incase one burst.....well the valve was going bad. Replaced both hoses - never had a problem again. But anyways... here are the other tests...

1. Is the incoming water flow normal?
Yes. Go to step (4). No. Go to step (2)
2. Are the incoming water faucets turned completely on?
No. Turn water faucets on. Yes. Go to step (3).
3. Is the incoming water pressure above (30) psi.
No. Have customer correct pressure problem.
Yes. Check for kinked or blocked incoming water hoses, clean
the incoming water screens. If problem still remains, replace the
water inlet valve assembly.
4. Does the fill water continue enter the washer?
Yes. Go to step (5). No. Go to step (6)

5. Remove power from the washer. Did the water fill
stop?
Yes. Go to step (6) No. Replace the inlet valve assembly.

6. Good models, check the pressure switch.
Pressure switch checks good. Go to step (8).
Pressure switch checks bad. Replace pressure switch.

7. Better models, replace the pressure sensor.
If this did not correct the problem, go to step 8.

8. Replace the control board.
Good Luck!!!

GOOD LUCK!!!!

My cabrio wtw6200sw2 has F50 code and won't spin I can't seem to find out what the code means. Could it be the motor coupler or controller board?


The F50 code for the Whirlpool Cabrio is most commonly a Motor Control Board failure.

Motor Stalled
F then 50 flashes when the motor rotor position sensor (RPS) senses no rotation.
? Does basket turn freely? If not, make sure bottom shipping pack has been removed. Determine cause of friction.
? If basket turns freely, see TEST #3, page 4 of the Diagnostics and Repair manual.

The Diagnostics and Repair manual can be downloaded as a PDF document file here:

DIAGNOSTIC TESTS
There are three diagnostic test modes available: Automatic, Manual and Console. These tests allow the factory or service personnel to test and verify all inputs to the machine/motor control. You may want to allow the automatic test cycle to complete prior to going into specific troubleshooting tests.

ACTIVATION OF AUTOMATIC DIAGNOSTIC TEST MODE
  1. Be sure the washer is in standby mode (plugged in with all indicators off; or with only the Clothes Clean or Done indicator on).
  2. Select any one button (except POWER, START, STOP and PAUSE/CANCEL) and follow the steps below, using the same button (remember the button):
  • Press/hold 3 seconds.
  • Release for 3 seconds.
  • Press/hold 3 seconds.
  • Release for 3 seconds.
  • Press/hold 3 seconds.
  • If this test mode has been entered successfully, all indicators on the console are illuminated for 5 seconds with 88 showing in the Estimated Time Remaining two-digit display.
  • If indicators do not display as described above, the press/hold/release procedure above may not have been performed within the time frame necessary for successful entry. Repeat step 2 to ensure this was not the cause.
  • If still unsuccessful, see Diagnostic: Unsuccessful Entry.
  1. The program then checks for saved fault codes:
? If there are no saved fault codes, all indicators on the console will momentarily turn off, then
turn back on with 88 displayed. After 5 seconds, the Automatic test, below, begins.

DIAGNOSTIC: Automatic
Performs a five-minute automatic test with water functions to check major washer functions (door can be open). Press the same button used in step 2 above to advance through automatic test steps.

NOTE: Basket must be floating in order to agitate.

I just bought a Samsung DV665JW dryer. Before it is completely dry, it stops, shows "end" on the display. I didn't take out the clothes for a while and then after about 15mins, it started drying again, then stop after a few mins, then after about 10-15mins it starts again...I stopped it and started the cycle altogether, again it stopped before completely dried and does the on, off, on, off....What's wrong with it????


This sounds like it is on a permanent press cycle. When it says end the clothes are dry.

Having said that....... If it is NEW this is a warranty repair. The moisture sensor is most likely the culprit causing the end of cycle trigger pre-maturely. Check around the moisture sensor for anything like bobby pins, straight pins, toothpicks (i.e anything foreign. Check the 2 strips and along the edges thoroughly for any foreigen matter.

If it is 2nd hand the moisture sensor is probably bad and passing false dry signals to the control. Again check for foreign debris before even thinking about replacing parts.

If you find nothing then before you buy parts there is a test for the moisture sensor. Just respond here and we can go from there.

Moisture Sensor Location


It could be the sensor. However, check the exhaust vent for restrictions first. you can test the moisture sensor Damp Dry Test 1. Set the following Timer- DAMP DRY Fabric Care/Temperature switch- COTTON HIGH Wrinkle Guard switch- OFF Signal switch- LOUD Door- must be closed 2. Press the PUSH TO START switch. After approximately 16 seconds, the Timer will start to advance to the OFF position, and the ?End of Cycle? signal will sound. If one or more of these functions do not occur, proceed to the Factory Test. Factory Test The Factory Test allows factory/service personnel to test and verify all inputs to the Even Heat control. The basic operation of this test is to notify the operator with an audible beep every time the status of an input to the control changes state. Activating the Test Mode 1. Set the following configuration: Door- must be open Fabric Care/Temperature switch- AIR FLUFF Signal switch- LOUD Timer- TIMED DRY OR AUTO MOISTURE SESING PLUS selection 2. Turn the Wrinkle Guard switch from OFF to ON three times within a five second period. A single beep will sound to indicate that the factory test mode is activated. NOTE: If any of these initial conditions are not satisfied, the control will not enter the test mode. Test Mode Functionality When the control is in the Factory Test mode, every input change of state will result in a beep (with the exception of the Signal switch). This includes: Door switch Moisture Sensor (short/open Sensor will result in a beep) NOTE: A moistened finger or damp cloth may also be used. Fabric Care/ Temperature switch Wrinkle Guard switch Push to Start (PTS) switch (with the door switch closed) Timer (any cam input change will result in a beep) NOTE: Timer will advance during test. If any of the inputs do not result in a beep, proceed to the following component tests If the dryer shuts off too soon when set to the AUTO MOISTURE SENSING PLUS cycle, check the following: -HARNESS/CONNECTION -MOISTURE SENSOR -THERMISTOR -EVEN HEAT CONTROL Procedure: 1. Test the Moisture Sensor by following the procedure outlined in ?Factory Test?, beginning on page 3. If the Moisture sensor fails the ?Factory Test? (does not produce a beep sound), check the Moisture Sensor. a. If there is continuity to Ground for Yellow/Red (Y/R) wire with no load, look for a short in the Sensor or Y/R wire. Verify harness connections both at the Sensor and the Even Heat control. b. If the Sensor and Y/R wire are good, replace the Even Heat control. 2. If Factory Test passed, verify thermistor by performing test procedures outlined in ?Thermistor Test? 3. If problem persists after replacing Moisture Sensor and thermistor
