Whirlpool washing machine

ERROR - FH
No water detected entering machine or Pressure switch trip not detected.
If after 30 seconds the control does not detect water entering machine and then 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 meter 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.
Causes and Solution
# 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.
Pressure Switch Hose is in good condition and properly connected to Tub and Pressure switch.
# Verify there is not a siphon problem.
# Verify wire harness connections to; Inlet Valves, Pressure Switch, Drain Pump, Flow Meter, and Central Control Unit (CCU).
# Check all hoses for possible leaks.
# Verify pressure switch operation.
# Verify flow meter operation.
# Verify CCU operation.
ERROR - F02
Long Drain If the drain time exceeds 8 minutes, the water valves are turned off and F02 is flashed.
Press PAUSE/CANCEL twice to clear the display.
NOTE: After 4 minutes the “Sud” error will be displayed, then 4 minutes later the F02 error code will be displayed.
Causes and Solution
# Check the drain hose and make sure it is not plugged or kinked
# Check the electrical connections at the pump and make sure the pump is running.
# Check the drain pump filter for foreign objects.
# If the above does not correct the problem replace the pump.
ERROR - F05
Water temperature sensor error If during the water heating step in the wash cycle, the
water temperature sensor (NTC) value is out of range, or
the heating element circuit has failed, the F05 error code
will be displayed.
Causes and Solution
# Check the Water Temperature Sensor, Heating Element and Element Relay
# Check connections to the Sensor, Heating Element and Relay
ERROR - F06
Drive motor tachometer error The control is unable to properly detect motor speed and
the machine will shut down. If a failure occurs during
high-speed spin the door will be unlocked after 3
minutes.
Causes and Solution
# Check wire harness connections between the Drive Motor/Tachometer and the Motor ControlUnit (MCU), and between the MCU and the Central Control Unit (CCU)
# Check the Drive Motor
# Check the MCU
# Check the Wire Harness
ERROR - F07
Motor control unit error The Central Control Unit has detected a short in the motor control unit. If a failure occurs during high-speed spin the door will be unlocked after 3 minutes.Causes and Solution
# Check wire harness connections between the Drive. Motor and the Motor Control Unit (MCU), and between the MCU and the Central Control Unit (CCU).
# Check the MCU.
# Check the Drive Motor.
# Check the Wire Harness.
ERROR - F09
Overflow condition If the Overflow contact on the pressure switch is Closed for more than 60 seconds an Overflow condition will occur. In an Overflow condition, the Door will remain locked, and the Drain Pump will run constantly, even if PAUSE/CANCEL is pressed twice and the Display is cleared. Unplug the unit to service.Causes and Solution
# Check the drain hose and make sure it is not plugged or kinked
# Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU).
# Check / Clean Drain Pump Filter of foreign objects.
# Check for Drain Pump Failure.
# Check the Inlet Valve for proper shut off.
# Check the Pressure switch for proper operation.
ERROR - F10
Motor Control Unit (MCU) heat sink thermal trip
If the thermal protector on the MCU heat sink gets too hot, it will open the thermal protector on the heat sink which will stop motor functions and an F10 will be displayed.
Causes and Solution
# Check for Proper Installation, verify the unit is not located near a source of heat and has proper ventilation.
# Check Wire Harness connections to the MCU, the motor, and Central Control Unit (CCU).
# Check the Drive system for any worn or failed components.
# Check MCU.
# Check Motor.
ERROR - F11
Serial communication error Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.Causes and Solution
# Check Wire Harness connections to the MCU, the motor, and Central Control Unit (CCU).
# Check the Drive system for any worn or failed components.
# Check MCU.
# Check CCU.
# Check Motor.
# Check Wire Harness.
ERROR - F13
Dispenser circuit error If the dispenser motor is not able to be driven to it’s proper position.Causes and Solution
# Check mechanical linkage from dispenser motor to the top of the dispenser.
# Check Wire Harness connections to the dispenser motor and Central Control Unit (CCU)
# Check Dispenser Motor.
ERROR - F14
EEPROM error The Central Control Unit (CCU) receives it’s data from an EEPROM onboard the CCU. If there is an error reading this data it will cause this error.Causes and Solution
# A power glitch may cause this error. Try unplugging the Unit for two minutes to see if that fixes the error.
# Check CCU.
ERROR - F15
Motor Control Unit (MCU) error If the MCU detects multiple resets or errors during a
wash cycle it will go into this error mode.
Causes and Solution
# Check Wire Harness connections to the MCU, the motor, and Central Control Unit (CCU).
# Check Drive belt.
# Check MCU.
# Check Motor.
# Check Wire Harness.
ERROR - Sud
SUDS 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.
Causes and Solution
# If too much detergent was used, run the unit through a Rinse/ Spin cycle then a Normal cycle without adding any detergent. This should clear the unit of the excess detergent.
# Check the drain hose and make sure it is not plugged or kinked.
# Check Wire Harness connections to the Drain Pump, Pressure Switch, and Central Control Unit (CCU).
# Check / Clean Drain Pump Filter of foreign objects.
# Check Drain Pump.
# Check the Pressure Switch.
# Check CCU.
FdL Door lock error A Door Lock Error occurs if the door cannot be locked. It will try to lock it 6 times before displaying the error.Causes and Solution
# Door Lock Mechanism broken or removed from the Door.
# Check Door Lock/Switch Assembly.
# Check the wire harness connections to the Door Lock/Switch Assembly and Central Control Unit (CCU).
# Door Lock/Switch Assembly Failure.
ERROR - FdU
Door unlock error A Door Unlock Error occurs if the door cannot be unlocked. It will try to unlock the door 6 times before displaying the error.Causes and Solution
# Door Lock Mechanism broken.
# Check Door Lock/Switch Assembly for foreign objects
# Check Wire Harness connections to the Door Lock/Switch Assembly and Central Control Unit (CCU)
# Door Lock/Switch Assembly Failure Replace failed component.
Note: The door lock/switch assembly can be manually unlocked.
To Manually unlock the door lock system:
1. Unplug the power cord from the outlet.
2. Remove the lower toe panel.
3. Reach up along the inside of the front panel and locate the bottom of the door latch assembly.
4. Located on the bottom of the door latch assembly is a tear-drop shaped tab.
5. Gently pull the tab down about 1/4 inch or until a click is heard.
6. The door may now be opened.
