Fault code f05 whirlpool microwave

Hi. This is a water temperature sensor issue.

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.

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 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
