I know it's two-speed, both speeds work for final spin on the Regular cycle.
More details. Connected it to water tonight. With water level on Small, it filled to what should been Large, and kept filling, so apparently either the pressure hose is blocked or the switch is bad. Went through Small, Med & Large, no difference, kept filling. There's also a leak, heard a steady drip-drip-drip hitting the base.
Don (the machine's owner) said he had to manually advance the timer until it started running, else it would overflow. I don't find anywhere on the timer for agitation to run until the pressure switch is satisfied ... so *apparently* he'd load clothes and detergent, let it fill to some point, and advance the timer to SPIN, then repeat for rinse ... not realizing that his clothes weren't getting washed at all. He got a new machine from Sears, I don't know what brand, didn't ask. If it's a DD Kenmore, his clothes won't know what hit 'em after running for who knows how long through a non-agitating 1970 Maytag.
