What could cause the washing machine to stop before the rinse cycle

appliancesdrainagerepairwashing-machine

My washing machine will get stuck right before the rinse cycle. The washing machine will be full of water. The way to "fix it" is to twist the knob right after the "rinse" line, find the sweet spot, and pull the knob out. It can take 10+ tries to find this sweet spot and seems to have no rhyme or reason.

I've read online that this might be a drainage problem, but I'm not sure that is the case here. I'm basing that off of the fact that allowing time to pass doesn't increase the likelihood of hitting the sweet spot.

Anything I can check? As the pictures show this is a Whirlpool Ultimate Care II

Sounds like the timer-switch is dirty or worn, based on the fact there's a sweet spot that works. If the timer is stuck, i.e. it never reaches the end of the cycle on it's own, the gear teeth are probably worn in that spot.

If the timer works, it just 'misses' the rinse, you may be able to access the contacts and clean them. If the gears are worn or broken, you'll probably have to replace the whole assembly.

Since you can get it to work in the sweet spot, that rules out the usual suspects like control valves, relays, pumps.
