      [Webinar] Samurai's Sealed System Sleuthing Secrets - 10/30/2017 @7PM ET   10/19/2017

      Having laid some theoretical groundwork in the last webinar, we're going to focus on practical considerations in this one. That means quick n’ dirty techniques for diagnosing sealed system problem using strategically chosen and skillfully interpreted temperature measurements.  Review homework from the first session on 10-2-2017. Home refrigerator practical design and operating rules-of-thumb useful for troubleshooting Practical application exercises Troubleshooting scenario exercise Techniques for making system temperature measurements for determining superheat and subcooling Sealed system diagnosis homework assignment (to be reviewed in the next webinar in this series) If you attended the first webinar in this series, this is your payday! We’re going to apply that keen, penetrating insight you now possess into money- and time-saving shortcuts you can use to diagnose real-world refrigeration systems on service calls.

How to troubleshoot a Whirlpool Duet washer with F05, F02, SUD, and FH error codes

Samurai Appliance Repair Man

7,038 views

F02 LONG DRAIN

If the drain time exceeds eight minutes, the water valves are turned off and “F/02” is flashed.

Press PAUSE/CANCEL two times to clear the display.

NOTE: After four minutes the “Sud” error will be displayed,

then four minutes later the “F/02” error code will be displayed.

Possible Causes / Procedure

1. Check the drain hose and make sure it is not plugged or kinked.

2. Unplug washer or disconnect power.

3. Check the electrical connections at the pump and make sure the pump is running.

4. Check the drain pump filter for foreign objects.

5. Plug in washer or reconnect power.

6. If the above does not correct the problem, go to step 7.

7. Unplug washer or disconnect power.

8. Replace the pump.

F05 WATER TEMPERATURE SENSOR

If during the water heating step in the wash cycle, the water temperature sensor (NTC) value is out of range,

the “F/05” error code will be displayed.

Possible Causes / Procedure

1. Unplug washer or disconnect power.

2. Check the water temperature sensor. Refer to the “Water Temperature Sensor” section.

Check connections to the water temperature sensor.

3. Check resistance of heating element, if present on this model. (abnormal = infinity)

SUD SUD LOCK (OVERDOSE OF DETERGENT DETECTED DURING THE WASH CYCLE)

The motor control unit senses a suds lock condition by analyzing the current draw on the drive motor.

If “Sud” is displayed a potential Suds Lock is detected.

This may signify a bad pump, an extra heavy load, excessive detergent, or excessive suds.

Possible Causes / Procedure

■ If too much detergent was used:

—Run the unit through a Rinse/Spin cycle.

—Run a Normal cycle without adding any detergent.

This should clear the unit of the excess detergent.

1. Check the drain hose and make sure it is not plugged or kinked.

2. Unplug washer or disconnect power.

3. Check wire harness connections to the drain pump, pressure switch, and Central Control Unit (CCU).

4. Check/clean drain pump filter of foreign objects.

5. Plug in washer or reconnect power.

6. Check drain pump.

7. Check the pressure switch.

8. Verify CCU operation by running a Diagnostic test or any cycle.

FH NO WATER DETECTED ENTERING MACHINE OR PRESSURE SWITCH NOT TRIPPED

If after 30 seconds the control does not detect water entering machine,

the valves will be turned off and the error code will be displayed.

OR If the control has turned the water valves on and after 8 minutes the flow sensor has detected 10.5 gallons

of water passing through it, but has not detected the pressure switch trip,

the valves will be turned off and the error code will flash.

Press PAUSE/CANCEL twice to clear the display.

Possible Causes / Procedure

■ If there is no water in the unit:

—Make sure that both valves at the water source(s) are turned on all the way.

—Check for plugged or kinked inlet hoses or plugged screens in the inlet valves.

—Verify inlet valve operation.

■ If there is water in the unit:

—Verify drain pump operation.

—Verify that the pressure switch hose is in good condition and properly connected to tub and pressure switch.

1. Verify there is not a siphon problem.

2. Unplug washer or disconnect power.

3. Verify wire harness connections to inlet valves, pressure switch, drain pump, flow meter, and Central Control Unit (CCU).

4. Check all hoses for possible leaks.

5. Plug in washer or reconnect power

6. Verify pressure switch operation.

7. Verify flow meter operation by blowing air through the part and measuring the resistance.

8. Verify CCU operation by running a Diagnostic test or any cycle

seems like some classic symptoms of a bad Pressure Sensor

from not using HE detergent
