What reason could be for a food processor's motor to run backwards?

[Benny7440]

Have a mini food processor that was given to me a long time ago that never was used and about two days ago tried to make a pureé but much liquid came out of it making a big mess. When, later, I made it to turn without any liquid inside noticed that, according to the blades, it was going in the wrong direction. Don't know if it has been tampered or serviced before it came to me.

I don't know it it can be noticed at the uploaded image but the plastic material that holds the blade is a little cracked; this alone tells me that it was abused a little or it was used for something correctly after it started to go in 'reverse'.

Is there something that can be done to make the motor going in the right direction? Thanks in advanced for any idea as to how to proceed!

Generally these appliances have brushed Universal motors that cannot be reversed very easily unless it is built into the appliance.
Is it possible to view the motor to get a better idea?

Has the blade been refitted and put in 'upside down'? Might explain why the plastic is cracked?

Thanks for replying!

Interestingly, the blade fits the base perfectly even though it says is mfg'd. by Sharp, this could mean that the parts aren't meant to be used together...

Appears to be a Universal motor if it does in fact have brushes, these have the field in series with the rotor, and it requires changing the polarity of one of them with respect to the other to change direction.

Do you mean to interchange the brushes cables?

No wonder it runs backwards. Even the label is reversed .
Seriously though, the cracks in the plastic blade-holder suggest someone has at some point removed the blade assembly from the motor shaft and re-assmbled things arse-about-face. Given those cracks, the assembly could disintegrate. I'd be reluctant to use the processor.

That would be one way.

We have a juicer that reverses direction every other time the fruit is pressed down on the top

Wiring problem, I guess? Or is there a secret reversal function that you never noticed? The ones I saw at healthykitchen101.com can go clockwise and counterclockwise, so maybe give it a shot.

In that case that is feature. Minde does, too.
