DADoES:
Your parent's KAWE670B is the exact same model I had. Except mine had suffered some damage from an abusive owner. The clear plastic that goes over the indicator dial on the timer was busted off. The timer knob was stripped, so you could only advance it by turning the indicator its self. I assume that's why the clear plastic was missing. So yes, it needed a new timer. There were some chips in the porcelain inner tub, and the bottom was also scratched up badly. The chrome part on the fabric softener dispenser was crusted with scale buildup and rust. Overall, my KitchenAid was so gummed up with hardened detergent and fabric softener that it was literally inoperable. It also leaked down the clogged up bleach dispenser, which, I guess, somebody confused with a detergent dispenser.
I just have to wonder if that machine is still alive, even. Last I heard from the buyer, it was working running just great. It's too bad, really. I am sure I could have done more to save it by offering the nice lady a shredmore with a good timer instead. What was I thinking?
