My Whirlpool Ultimate Care washer, model # LSR8233EQ1, will not advance to the next cycle and agitates too slowly. I bought it off of Craigslist List. When I first tried it, it stayed on Wash for 50 min until I manually moved the dial. Then it stayed on Spin until I manually moved it. I don't think it even rinsed. It agitated real slowly. I don't think it's the timer, because I can hear it clicking the entire time. I looked inside the panel, and the black plastic tab you're supposed to pull partially out to remove the front dial appears to be broken. It looks like one of the two tabs sticking off of it is broken off. So maybe it can't function properly with only the one tab. I researched timers, & they seem to go for around $150. I only paid $75 for the machine, and I think all I need is that tiny black plastic piece. Any help you can give me would be greatly appreciated. Thank you so much for your time.
