Here is a tech sheet, see the attachment.
As you can see from the tech sheet it could be that the unit is trying to achieve a water temperature set point but is not getting there.
Could be a bad heater, high-limit thermostat, thermistor or control board.
I am assuming that every thing looks normal.
Try a cycle where no heat is require. Does it now complete t he cycle?
If yes then the above is probably happening.
What is the Thermister? What does it do?
It is a solid state device that changes resistance with temperature (lowers resistance as temperature rises).
Tells the unit what the actual temperature is.
