When your kitchenaid classic plus ksm75wh is most likely to develop issues, based on community repair data and manufacturer patterns.

The most common failure types, sorted by when they typically appear.
The motor windings overheat from exceeding recommended batch sizes, running at high speed with heavy loads, or continuous operation without rest periods. Thermal overload protection may trip (mixer shuts off and resets after cooling), but repeated overheating degrades winding insulation and can cause permanent motor burnout. Budget models with smaller motors (250-350W) are most vulnerable.
The speed control plate (phase board) uses sliding electrical contacts to regulate motor speed. Over time, carbon buildup and arcing erode the contact surfaces. The mixer may run at only one speed, spark when adjusting speed, fail to start, or run intermittently. Replacement parts are inexpensive ($15-25) and widely available.
The mechanism that secures the bowl to the base wears from repeated attachment and removal. The bowl may spin during mixing, walk off the base, or detach unexpectedly. KitchenAid bowl-lift models use twist-lock pins; tilt-head models use a bayonet mount. Budget models use clamps that fatigue faster.
