My temperature light comes on stops my canister vac, I have several times since (days have passed) and the unit will still not come on…only the temperture light comes on. Do I need a new motor? My unit is 17 years old but was serviced within the last 12 months.

Miele vacuum S4212 Polaris with SBD 450 - 3 Combination Carpet/Smooth floor tool
(Recommended for: short-pile carpeting, area rugs and smooth flooring)
S4212 Neptune with STB 205-3 Turbo Comfort Brush
S5281 Callisto with SEB217-3 Powerbrush
(Recommended for: medium-to high pile carpeting, area rugs and smooth flooring)

Your 6500 is equipped with a thermal switch that will shut down the motor when it senses too much heat. Sounds like this thermal switch is faulty.
