Gets Stuck In Washing Cycle

My dishwasher gets stuck at the washing cycle . I have to click once clockwise to help it complete the cycle or else it will keep running. Seems like the timer might have an issue, but could it be the thermostat as well. Kindly help me as I dont want to replace the dishwasher at this time.

If the cycle runs OK with both temperature boosts off then it is probably just the timer.
