Wade for Model Number GTW460ASJ9WW Hot water fill does not appear to work. Machine fills tap cold water when set to Hot or Warm. Fills warmish when set to Colors. Ran error codes, none relevant. Ran diagnostic test on Hot water and then Cold water valves and both work fine, plenty of hot water into machine during diagnostic test. Ran Analog Knob diagnostic and all knobs worked fine EXCEPT Temperature Switch which had inconsistent blinking behaviors when rotating knob. Light is supposed to blink faster when you rotate right but it would REMAIN blinking same frequency from Cold through to Hot setting – or suddenly change frequency and blink faster –but would not consistently change blinking speeds as I rotated dial: sometimes slowing, sometimes speeding up. This leads me to believe the Temperature control is malfunctioning. Looking at the parts list I'm lead to believe the control board TL27 needs to be replaced. Thoughts?
Answer Wade, Based on the information provided this does sound like a possible issue, but you may want to look at the selector switch assembly as well. Read More... Answered by AppliancePartsPros.com | Thursday, December 2, 2021
