Hi I have had this Kenwood chef forever. I did have the gears replaced once and now on using for a few minutes, I get an electrical burning smell. I can use for short periods at a time but if used for a long period then smoke is visible. The machine still works but I need to know what is wrong and have it repaired. Any advise? It is an A901D.

The smoke will be coming from the motor.

It's more than likely that the motor's brushes are not making best contact with the commutator and heat is being generated. Left to run long enough the build up of heat will destroy the motor. And with each successive use it will become worse- you will not know exactly when it will self destruct.

There is no smoke without fire - they say.

Have it serviced/repaired or buy a new one.

Good luck...

I have just worked it out "forever" means for a long time -it does not mean the particular model...
