Timer has small gear pull panel off and see if gears are stripped in one spot meaning no teeth on the gears

The timer control module or control board is faulty at this point. you will need to replace the timer or, control board asap. this will fix this issue.

Water is not spraying through top spout and its making a weird noise...

the timer is bad.the 42 min cycle and the 6 min cycle share the same timeline.try northernparts.com for the part number and price.installing the timer isnt that difficult.

sounds like a bad timer

does the timer advance the control knob? check to see that nothing is in the way of the center spray tower. does it sound like any water is spraying around inside?

Most of the dishwasher has a Thermal hold period in which the machine will not advance to the next cycle until the water temperature reaches a specific degree. it is possible that your aqwa sensor/or heater is bad OR as in most of the cases, the Timer relay that is responsible in turning the heater on is stuck open, in this case you need a new timer. So,Check Timer/Aqua sensor/Heater
