The dishes were not getting very clean, so I started to do some investigation. Turns out that there were two issues.
The first is that a rubber gasket on the back assembly had bro off and fallen down the assembly and I assume restricting water flow.
The second was that it just needed a good cleaning out down by the food grinder. Found some pretty interesting stuff down there.
I followed a very good video on you tube that can be seen below.
