the "blue" light that controls the cold water is supposed to come on periodically while cooling the water and then it will go off. The "red"l ight that controls the hot water does the same. Now, the "blue"light remains on all the time. I can hear machine switches on for a several seconds and then shuts off. However, the water is not cold like before.
The hot water control is functioning fine. What is wrong with the cold water control?
