What makes an older Wascomat whistle as it spins up/down? |

Don't know about revving up, but screeching sound as spin ends likely is caused by belt being stopped instead of coasting down.
My Miele will do this if one stops spin cycle by advancing timer past a certain point. Say if timer stops spin cycle, but while drum is still spinning timer moves over to "pulse/fluff" portion. There is a loud screech as drum quickly stops, then all is quiet as it starts to tumble to and fro to fluff wash. At one point thought this would harm the belt, but once when Miele repair tech was working on Big Bertha and put an abrupt end to spin it made same sound. Asked if doing so harmed the machine, and was told "no". That "Miele used commercial quality belts on these washers. In fact copy of service manual have for W770 says same thing, that washers have high quality commercial belts and stopping spin quickly (as say part of diagostic testing by a tech), won't cause harm. For the record every front loading washer I've used or seen at laundromats makes that same screeching sound as machine stops spinning. |

Just to add my two cents, I agree with Cam and Gizmo above. When the machine is slowing the drum from spin, that is dynamic braking, as explained above uses the motor to slow the drum down. My Kenmore He5t and Miele front load washers also do this at times, depending on the cycle, but it’s not nearly as pronounced or loud as the commercial machine above! Kevin |
