I have a Maytag MHW6630HW2 and only on heavy duty with steam on is it filling with hot water. The other cycles are filling with cold water despite being on the highest temperature setting when I open the dispenser to feel the water. We\'ve tried with both a tank water heater as well as a tankless one and the washer is right beside both water heaters. Hot water works in the rest of the house. A Maytag technician came out and replaced the control board to no avail, and wants to replace it with an updated version which is on backorder for 5 weeks.
