My Kenwood MX270 patissier doesn't work anymore. I've opened it and checked the brushes (still enough length) ; micro switch also is working. Which component on one of the two prints are suspicious?

You cannot bypass that board. Just order a new one: http://www.buyspares.co.uk/patissier/mx270/speed-control-pcb-assembly/product.pl?pid=963017&shop=kenwood&path=590806&model_ref=959620

Follow the power, start looking wherever the power stops. Sometimes it can help to reverse phase & neutral to track where the power stops from the other side too. You are only doing this for testing purposes and need to put it back as it should be when you're done.

hi if you still have problems email me and i will try and talk you through,
it may be the belt (teeth worn out) or the pulley (same problem).
the info given in your post is very vague.
if its the teeth on either the belt or pulley there is a simple fix.
remove bottom of base with screwdriver there should be screws under the feet of machine. use a bike valve screwdriver to remove the two remaining screws(depending on make and model)
remove belt, put RUBBER BAND

hi Ashley, I have the same problem as you. did you fix it? is there a triac in this device? how did you disassemble?

Hi. You have a broken gear in the gearbox either the first motion gear is loose on its shaft or less likely the vertical big gear is loose on its shaft. independent spares for the gearbox are available or complete gearbox

Does the actuator push down far enough to catch the button at the bottom? I repaired one simply by adding a vinyl screw cover to the top of the button so it was tall enough to be reached by the actuator.

i have the same problem. i bought a kenwood fp921
im sure about locking bowl and lid.
but the drive shaft is loose. it doesn't work

Hi there,
I am trying to open a Kenwood p?tissier MX270 s?ries to hava a look inside.
How do I remove the top to get access to it please?
Kind regards,
Sam,

sounds like the motor armature is burn. Dissemble the unit, remove the motor. Loosen the bolts running from end to end of the motor and with emery cloth, clean the small metal plates on the ehd of the armature. They should be bright copper colour. I the armature is burnt, they will be dull brown. The other thing is to replace the brushes in the motor.
