Whining and squealing noises from dishwasher pump
Most likely this is caused by the carbon and ceramic water seal, the sound will come and go, should not worry about it.
It can get worse if the dishes are being put in with very little food soil on them oils, etc., also using too much detergent versus the soil level of the load will make it worse, You may be able to hone the seal by washing a few loads with a tablespoon of bonami cleanser dumped in the dishwasher. Sometimes this will stop the noise. John | ||

if not the above,older ball bearings will sometimes make that noise-nothing to worry about if it is the bearings either :) | ||

 Give us a video clip of the noise. It could be the motor bearings or the carbon seal, they both have their own distinct noise. Noise from the carbon seal is nothing to worry about (usually the sound comes and goes), the motor bearings are (noise never goes away, the motor comes to a sudden halt instead of spinning down while stopping). | ||
