well hopefully you have let something get in the motor and jam it
dont know on this model but sometimes you can use a mirror and a torch in the sump when you have dried out the water, to look at the fan to see if you can see any obstruction
failing that the motor has got to come out to be checked
never done one of these myself

and if it needs a new motor it may be this one , you would need to double check
