You kinda have to see what happens when turned backward. It would be immediately obvious if you saw the timer internals.
Instead, hold your left hand horizontal at eye level. That's the timer contact. It's thin springy brass. Now put your right hand straight up/down under your left knuckles. That's the cam the contact rides on. Now move your right hand to the right until your left fingers fall off the 'cam' (below the right fingertips). That's turning clockwise, the way it's supposed to work. Now try to back up your right hand toward your left. That's turning counterclockwise. If you use enough force holding both hands rigid, it hurts. There is a pawl to keep you from turning it backwards. But it is only "so" strong. If you break that pawl the timer may still work, depends where the broken piece ends up. If you turn it backwards from there past a program step, the timer will at least have to be disassembled before it works again. Or it may be damaged beyond repair and need replacement. Why can you generally turn a dryer timer either direction? The cam design is different, and there is a clutch between the knob and the motor. Mechanical washer timers are almost exclusively clockwise only (I can't think of an exception but there could be one). |
