STM32F3 PWM output problem

Hi everybody,
I am trying to use the PWM Output feat of the board's timers. In particular, I am trying to use TIM3 to drive some DC motors.

I found an example in the CubeMX material which used the same timer to do this, and I set up my code in a similar way. I tried with both TIM1 and TIM3, and what turned out is that, while TIM1 seems to work flawlessly, when I put to 0 the value of the pulse for TIM3 the output is still different from 0 (approximately 2.3/2.4 V).

Can anybody explain me what is happening? (unfortunately I only have a tester, so I can't see the waveform on an oscilloscope)

EDIT: this only happens on channel #1 (PE2)
