Code F05 Description: Water temperature sensor error. If during the water heating step in the wash cycle, the water temperature sensor (NTC) value is out of range, the "F05" error code will be displayed.
Possible Causes / Procedure: 1. Unplug washer or disconnect power. 2. Check the water temperature sensor. Check connections to the water temperature sensor. 3. Check resistance of heating element, if present on this model. (abnormal = infinity).
Replace failed component.
Hope this helps (remember to rate and lave a testimonila about this free answer).
https://secured.whirlpool.com/Service/.../Duet%20Job%20Aid.pdf Above is your service manual, look in the area of the NTC sensor,it needs to be replaced, the service manual will show you how. You need to replace the ntc sensor, most likely.
F/05
Water Temperature Sensor Error If during the water heating step in wash cycle, the water temperature sensor (NTC) value is out of range, or the heating element circuit has failed, the "F/05" error code will be displayed.
Check the Water Temperature Sensor, Heating Element and Element Relay
Check connections to the Sensor, Heating Element and Relay
Water Temperature Sensor Error - Check the Water Temperature Sensor,Heating Element and Element Relay. If during the water heating step in 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 - Check connections to the Sensor,Heating Element and Relay.
"F05" is an indication of a water temperature sensor (NTC) error. Check the Water Temperature Sensor and check connections to the Water Temperature Sensor. The following link explains:
In many cases the electrical connection to the sensor comes loose due to washer vibration and needs to be reconnected.
The part number (if required) is 8181705 and listed as "NTC" at pcappliancerepair.com. Just type in your model number and you will find the part under the "Tub and Basket" heading as item 24. If the readings check good, post back and let me know. You may have problems in the heating circuit and/or a defective heating element. I hope this helps you.
If during the water heating step in the wash cycle, the water temperature sensor (NTC) value is out of range, the "F05" error code will be displayed.
Possible Causes / Procedure
1. Unplug washer or disconnect power. 2. Check the water temperature sensor. Check connections to the water temperature sensor. 3. Check resistance of heating element, if present on this model. (abnormal = infinity).
Replace any parts that is malfunctioning or defective.
Read through the link provided and let me know if you have any questions. The majority of the cases I have experienced are either a bad NTC sensor, or a loose/disconnected connector plug on the NTC.
If you require replacement parts, you can purchase at any of the following websites:
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.
Potential Causes
• Check the Water Temperature Sensor, Heating Element and Element Relay • Check connections to the Sensor, Heating Element and Relay
Replace failed component.(Most common issue will be a failed water temp sensor)
F05 error is an indication of a water temperature sensor (NTC) error, or Heating Circuit failure. Check the Water Temperature Sensor and check connections to the Water Temperature Sensor. To access, you will have to UNPLUG your washer and remove the lower access panel under the door. The panel comes off by removing the screws under the bottom edge.
Suggestion: If you place a block of wood under each front foot of the washer, it will make access to the screws much easier. If the panel sticks, a tap on the sides will knock it free. The panel will drop down then come off. The sensor (NTC) is located at the base of the wash tub in the front on the heating element. This will be a small square shaped plug between the heating element terminals. Unplug the wire harness and take a resistance check.
The ideal readings should be
Temperature Meter Reading 32°F (0°C) 35.9 K ohms 86°F (30°C) 9.7 K ohms 104°F (40°C) 6.6 K ohms 122°F (50°C) 4.6 K ohms 140°F (60°C) 3.2 K ohms 158°F (70°C) 2.3 K ohms 203°F (95°C) 1 K ohms
Finally, remove the washer top panel by removing the three screws holding the panel in place in the rear.Once the screws are removed, slide the panel back then off.Locate the Central Control Unit (CCU) directly behind the wash tub.Take a resistance check at the Heating Element Solenoid by removing connector 9 from the CCU (this is the second connector from the RIGHT as facing from the front).A reading across test points 1 & 2 should also read 15 ohms.

Roughly...around 9K ohms at room temperature if I'm reading the chart correctly. Take readings as listed and also double check the connector to make sure it is not oxidized. Try cleaning the plug and reconnecting to see if the error code goes away. If not, you will probably have to replace the sensor. If the sensor checks good, take a reading across the heating element terminals. It should indicate about 15 ohms.
Lastly, remove the washer top panel by removing the three screws holding the panel in place in the rear. Once the screws are removed, slide the panel back then off.

I hope you find this information helpful. I have seen this error code generated by something as simple as a loose connector on the NTC sensor. Hopefully, you can resolve this with no expense. If you do require any parts, however, you can locate parts with illustrations at searspartsdirect.com or repairclinic.com. If you require further assistance, please let me know.
