when spinning makes loud noise

Hi Liliana, If you could provide a more accurate model number, that would be very helpful. It should be in the back right hand corner, under the lid, or behind the main console. ex 110.4536836 something along the lines of that. regarding the the sound, does it sound like a Jet taking off and becoming progressively louder? If that is the case that is your bearing that is going bad and will need to be replaced. This repair can be very expensive, and in some cases not very cost effective to fix depending on model and age of unit. In some cases, there could also be something stuck in your pump that is bouncing around on the impeller (coins, bobby pin, nail, etc.)
Please get back with us with any addition questions and information.
