Bosch Dishwasher just has low "Growling" sound

Dishwasher justs “Growls” when turned on. Tried turning power off to see if system would reset- did not work. I think it may be the motor/ water pump as it was making a loud grinding noise about 2 weeks before it died. Is it the motor? if so, can use p/n AP2826384 which is for Model# SHU8802UC/12?
Thank you

Did you ever get to the botom of this? Did you fix it yourself?
