Manual washer works fine. rinse temp too low

If it is the whirlpool low water high efficiency washer purchased in the last 3 years. That's how it works. On the lid some models even show a picture to explain this or also look at the owners manual.

Rinse on most washers is cold water your wash cycles can be cold hot and even warm. Problem You may have is a bad water feed valve Or Timer and possible bad wire harness at motor to timer
check water valve Turn washer to regular wash cycle pull knob on will washer fill ?
if water starts to fill then change washer temp if washer has this.
if water comes out on all settings water valve is fine.
Check the water both hot and cold that it is turned on;at faucet.
Your Kenmore Most likely has a bad water valve check for hot water side clog or not working.

I would check with the vendor that sold you the unit and see what they have to say or send an email to the Contact Us link on their website and ask. I am guessing no mention of the in your owners manual?

Did you tried with different load?
It could be the control panel which is not to cheap.

Your rinse temperature sensor that is a tiny probe in the water piping (top rear of machine) needs replaced. Hobart part # 00-294692. It costs about $84.

heater not working .m/c is waiting for correct water temp.
to test try a cold wash only & machine should go thro full cycle

Your water valve is bad or the cold side of the valve is stopped up with sediment. Clean the water valve inlets. If that does not correct the problem, replace the water valve.

The MAH5500 series washers have automatic temperature control functions so the washer can control water temp regardless of water heater settings and other factors. I would say either your definition of "hot" is not truly "hot" (over 110 degrees), or the washer's ability to sense has failed (which would also affect fill temp on "wash" fills also). If someone has worked on the washer recently, maybe they reversed the wiring to the water valves inside the machine? ATC temps are as follows: Cold 70-90, warm 90-110, and hot is unregulated at 110 degrees and up. These are normal temp ranges for ATC controlled machines, and are completely safe for fabrics.

My guess would be that you have a faulty timer if you can manually move it and the operation of the washer resumes.
