I get cold water at start of fill cycle then when it adds water during wash cycle it adds hot water only , no matter what temp. you have set for the wash cycle?? Used to fill with cold on a cold setting and hot on a hot or warm wash setting . Now I get hot no matter what setting. Hoses and supply lines are good as well as screens and inlet valve. I do get cold on the rinse settings . If I shut off hot water supply so That only cold can get it in , it will hum at the dispenser like it is trying to add hot water during the wash cycle. IT does this on any wash setting. Bad inlet valve or ccu ??
ANSWER Hello Chuck,
You will want to check the thermistor. At the control board with unit unplugged at room temperature you will want to do a resistance check of the thermistor. here are the resistance readings that you should have:
32°F / 0°C/ 35.9K O
86°F / 30°C/ 9.K O
104°F / 40°C/ 6.6K O
122°F / 50°C/ 4.6K O
140°F / 60°C/ 3.2K O
158°F / 71°C/ 2.3K O
203°F / 96°C/ 1K O
If you are outside of these ranges then you would need to replace the thermistor W10467289.
