How do you know it is something under the tub? I t may be a faulty control board, motor, wiring, pump not draining etc. If you want to take it out. Remove the lid. Raise the top deck by removing the 2 screws at the front under the lid bumpers. Prise the 2 tabs at the back out from the cabinet and lift it up. Get someone to hold it up. Remove the top plastic trim ring around the bowl. Remove the agitator after first removing the wing bolt down the centre of agitator. Then pull the bowl up & out.
