How do you get to the interlock switch located in stand below transmission housing?

Remove the brush caps on the sides of the motor housing and check the carbon brushes. If they are worn out replace them. They are keyed and will only fit properly one way so be observant. If that's not the problem remove the back cover and check for broken wires on the black control plate. Make sure the switch on the bottom inside of the control plate is making contact. If still faulty check the cable for continuity to the control plate, cable connects to the black wire and the white wire on lower left of control plate. After that you need to check for continuity of the field coil windings. Only thing left after that would be the phase board pcb just above black speed control plate at the back.

Hi on my new Kenwood Prospero+ model khc29h0wh (but applies to all) I had same problem: dough mixer and high speed mixer working, but "medium speed" food processor and Juicer not working.
After lots of time I realised... the lid of the Juicer/Processor actually locks in three different positions, but only one of these (with the handle corresponding to a mark) actually locks lowering a white plastic security prong that activates the switch. It is the position in which the lid and container prongs coincide.

You have to trace from the power cord to the motor the supply .You will need to see where the problem is to cut power .

it can be a reset switch( if available in the unit), the main switch control.
if not it can be the motor, make sure the bowl locks well to latch the safety switch as some models the motor wont spin otherwise.

that fault is a b_gd.there are 10 things that can cause this.1.start sw.momentary contacts not closing. 2.stop sw. contacts open. 3.bowl guard sw. open or malfunction(b_gd)displayed on timer.4.contactor 1con malfunction.5.timerboard malfunction.6.wiring incorrect from sr drive to motor or 1con.7.sr drive malfunction 8.1 con monitor from control drive disconnected from contactor coil9.encoder malfunction 10.motor malfunction. hopefully just your bowl guard switch is no good. hope this helps, dont forget to vote, monomoy

You will need to confirm the model number. An H600 or L800 have a wheel to manually turn to raise and lower the bowl. The M802 and V1401 hav a belt driven bowl lift clutch, operated by a lever. When you push the lever up or down, you are engaging a small transmission between the motor and main housing. You would need to remove the top cover and see what's happenning. It may be there is something other than the proper spiral pin joining the lift lever to the clutch input shaft, giving alot of backlash and insufficient selector movement.

Unplug first. Mixers can detach from the bowl base. You may have a lockout either in the latch mechanism or in the beaters. Try removing the mixer head from the base and the beaters from their sockets. Then plug in and try switch. If not working, unplug and attach beaters. Replug and try. Then attach to base and try again.

Make sure speed control does not have safety feature requiring to press in before turning control.

Good Luck.

If you remove the bowl guard you will see a magnet that attaches on iy in a white housing.The scews come loose and prevent it from closing the switch.Also the switch which comes out of the top pedestal can be adjusted.Let me know.

if the mixer is pretty old then the timer is bad.If its a newer unit the timer or the bowl height sensor is bad.

CE is the marking that shows its european conformant.  I think the difference is mostly in terms of the no volt interlock switch.  This means the KA style N50 bowl won't work with the CE models - too low.
