Bosch electric dryer motor sounds horrible!!

8 posts in this topic

I have a bosch 500 nexxt series electric dryer. The motor sounds horrible so I replaced it with a brand new one. The new motor has the same problem, it's very loud and shuts off around 10 seconds. It smells like the motor is getting hot. I disconnected the blower wheel and the belt, no change. I don't see a capacitor anywhere. I'm not sure what to do next. I'm thinking maybe the relay or maybe the wiring is bad in the house or the machine (I just moved into this place). Any help would be greatly appreciated. Thanks!!

"double phasing" motors will overheat and sound terrible as the start winding and run winding are doing battle because they are energized at the same time...

what is the full model number of the machine as it appears on the model / serial tag?

I'm not sure what the model number is. I couldn't seem to find it. It's bosch nexxt 500 plus series buy don't know much more or where the model number is located.

The only numbers I see are on the inside bottom of the door 9000351388 and it's a bosch nexxt 500 plus series.

I figured out the problem. Turns out the wiring was incorrect inside the plug receptacle. The neutral and hot wires weren't in the right position.

Wrong from the factory, or did someone tamper with the evidence??

The dryer was wired correctly, the house I just moved into was wired incorrectly. I decided to put the bosch dryer on the back burner for now and bought another used dryer. That dryer gave me a e61 code. After a little bit of research I found the wiring was incorrect inside the plug receptacle attached to the wall. The neutral and hot wires were reversed. Fixed that problem and now everything works fine.

ahhhh, ok, I thought you were referring to the motor plug! They call that reversed polarity... thank you for the update.
