Brandon for Model Number WTW4816FW1 When the water temperature is set to hot the washer will dispense cold water, and then cycle to hot and cold water being dispensed at the same time, and then back to cold, etc. I believe this is normal, but the problem is that when it is done filling, the water is lukewarm at best. The same thing also happens when the washer is set to warm (although I'm not sure any hot water is cycled in). When the washer is done filling, it is cold. Also, the washer fills the tub quite full even when there is a very little amount of clothes in the tub (I don't know if this is a related problem, or even a problem at all). Thank you in advance for any help you can offer.
Answer Brandon, This washer has a thermistor in the water valve assembly and the board reads the temp from the thermistor as the water runs into the machine. Based on the temperature settings as to hot, warm, or cold it will use both the hot and cold valves to satisfy the required temperature. This is a feature called automatic temperature setting or ATC. These settings are pre-determined by the manufacturer to help save damage to clothing and to provide optimum wash temperatures for detergent and fabric softeners. Read More...
