Food Processors Diagnostics
There are many food processors on the market, and they all have their weak points.
One of the most common problems however, is the disc carrier breaking.
This can normally be easily replaced.
The bowls and lids tend to be subject to breakage too. It is more noticeable when the lid is damaged, as they tend to have an "actuator" protrusion which, when broken will not allow the machine to function.
Most parts for most makes are available
