My Kitchen Aid KSM150PS Artisan red mixer trembles alot and makes a grinding sound when I use it. I've exchanged it once already and have the same problem again.

See following video. Fast forward to 7:30 and it shows the on/off contact. Around a minute earlier it shows the the speed lever, spring, and link.

sounds like the set screw in the back unit is too tight. Take off the back cover with the single screw up top. On the switch assembly that is now revealed, run the switch back and forth to see how it is interacting. The small set screw at the bottom probably needs loosened or tightened to give you the other speeds.

Contact Kitchen Aid. My understanding is that they will take care of it evenif it is over year old. It would be worth a shot.

Hi,

The KSM150 is the line of mixers with similar features. It is in the Artisan series, tilt head, 325 watts. All mixers in the KSM150 line have the same features.
The one that you asked about, the KSM150PSMC is done in metallic chrome.
Best regards, --W/D--

bad sign seal and probably bearings time to go shopping can be repaired but time consuming.

Tap it back in. . Are you sure it is not a locking rod.?

It very likely sounds like a plastic gear that is worn. If this is the case, then a replacement is very likely stocked by the manufacturer only.

I advise opening the unit to identify which one you need, then 'phone the manufacturer with the make model and year of the product.

If they say they do not stock it - then I'm afraid that's as far as you can go with this.

I can not respond to the warranty issues. My kitchen aid mixer is past warranty as well. I live in a country that uses 220V and my kitchen aid mixer is 110V. I have been using my kitchen aid mixer for almost 4 years with no problems at all.

The converter boxes are supposed to blow the fuse on the converter before it reaches your appliance and cause any problems.

If you purchase a 220V kitchen aid (although it would cost more money) it would probably have more power because of the higher voltage.

Hope this helps!

Some of the gears may have broken or slipped off. You'll need t open it up to see why the shaft from the motor will not spin or you will burn out the motor with the power on trying to make it go. It might be a DIY job if you can see an obvious problem like a slipped gear, otherwise take it to a repair specialist.

We've found most all accessories at any place that sells the mixer. Bowls, beaters, meat grinders, pasta makers, etc.
