The split phase capacitor in the pump ages and looses it's capacitance, the pump then lacks the torque to start. The shaft seal may leak and allow liquid ingress leading to bearing failure and earth faults, or it could just get jammed by a large piece of debris in the impellor.

The most common cause of sump pump failure is a power outage. Sump pumps depend on your house for power, and blackouts can be problematic.

Water leakage through valve,gasket and bearing after working a certain period. Do a routine overhaul maintenance to it can avoid failure.

The float gets stuck in the up position so the pump keeps running when there is no water in the sump. No water, the pump over heats and burns out. Make sure the float is free and there is no way for it to stick.
