That problem is most likely a faulty circuit board in the canister. See if it still runs with the hose disconnected. If so, definately the P.C.B. Hose problems usually don't happen early in life with the Kenmores, and you have the standard hose without electronics, even less likely for problems. Get it repaired under the warrenty, the complete assembly is around 80 to 100, and unless you know how to work on the hose, it can't be serviced by the consumer. More questions?
