Code F 05

The "F05" error code is indicating a Water Temperature Sensor Error. Does it take long time for the water to get hot when you initially start it? If the water is cold entering the tub when hot water or warm water is selected it possibly could cause the error. It only makes sense because after you cancel the cycle and restart the washer it does OK because the cold water has been purged.

There is a thermistor located on the heating element mounting bracket which is used to monitor the water temperature. The heating element w/thermistor will be located on the lower back portion of the tub. You might find a loose wire connection on the thermistor. You will need to remove the rear panel to access the heater and thermistor. You will need an ohm meter to measure the resistance of the thermistor. See images below for specifications.

NOTE: Disconnect the power cord before removing the rear panel.

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.

Potential Causes:

Check the Water Temperature Sensor

Check connections to the Water Temperature Sensor

I recommend calling a service technician to diagnose and repair your washer.

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.

Potential Causes

• Check the Water Temperature Sensor, Heating Element and Element Relay
• Check connections to the Sensor, Heating Element and Relay

the f5 error code is to do with the water inlet valve not working it will need replacing in the mean time try connecting the cold water to the hot select hot wash and see if the water flows into the machine

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

"F05" 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. HINT: 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. Readings will be as follows:

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

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. 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

Hi there,

Well An F05 is a water temperature sensor error.

This occurs if there is a problem detected during the heating step of the wash cycle.

You will need to check the Water Temperature Sensor, Heating Element and the Heating Element Relay.

But as you says that your washer is only 4 months old so why don't you ask for warranty......
Please post comments if you need more help or information........

Good Luck!!

Thanks

F05 is a water temp sensor error ,could be a bad heating element, or the temp sensor may be faulty, try checking the connection's to the temp sensor and heating element, also check the element relay.

The following link expains the "F05" error code:

Check to see if the connector is still plugged into the heat sensor, first. I have seen where the connector has come loose and caused this error code. If not, take the resistance readings as recommended. I hope this helps you.
