Hi guys! The washer stopped working and a f24 error came on. I followed several steps from you, i.e. disconnected the washer for half an our. I also tried to follow the steps from http://voices.yahoo.com/how-fix-f-24-error-code-whirlpool-duet-7572384.html even though it is a different model. I got the schematics from behind the front panel and saw that the temperature sensor is marked with the wires TH4.2 and TH4.1. I opened the top, found the control unit but at the connection spot TH4 was no cable attached. At the wiring diagram it states that the "component not present on all models". Does that mean there is no temperature sensor? If there is no sensor, why does the error code pop up then? If there is a sensor, how can I locate it instead? Furthermore, could the f24 relate to a different problem and if yes, how could this be fixed? Thank you in advance for your help!
The sensor is located on the front bottom side of the tub. Here is the part to order.
Testimonial: "I found the sensor, the connector was loose. I plugged it in again and it started working. Thanks for the help!"

This advice is for Whirlpool Duet and Kenmore Elite model FRONT LOADERS displaying the "F24" Error Code. Some of the error codes on these model washers can be erroneous, however. The first step in troubleshooting any error code is to simply unplug the washer for AT LEAST 30 minutes in an attempt to reset the Central Control Unit (CCU). This is the main "brain" of the washing machine. If the error code reappears following a CCU reset, then you have a genuine problem.
"F24" 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 2 x 4 under the front feet 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. Make sure this plug is secure and not loose or unplugged. It is common for the connector plug to come loose due to vibration. If the plug is intact, check the contacts for corrosion. If everything appears as it should, then 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.

If it is not the plug at the bottom is ok and the temp. sensor is ok.Check the plug on the CCU on top mine was not even plugged in. When I plugged it in the washer started working. You have to take the top off to get to it,but it is easy. Three screws on the back top and the top will slide off easily. There is a troubleshooting manual in the front bottom panel on right side of panel. Page 10 troubleshoots the temp. sensor. The book gives you all the troubleshooting codes. The front panel comes off easily by unscrewing three screws on the very bottom of the panel.
