Not sure, I'll look into it when I have a bit more time. Did I mention previously that one of the yields came out at 73Kg!! I sent a bug report to the developers, but have had no reply. I suggest best to ignore it for now.
Russell, as soon as you have finished cooking something, tip it out and fill the TMX bowl with water. Use a baby's bottle brush ($5) at Safeway , it has a blue handle. and swish it around the bowl going up and down on the blades. If stuff like bread dough or mashed potato is stuck under the blades, just keep poking the bottle brush at it. I haven't taken the blades out for about 3 months. Good luck and hope you settle into your busy life soon.
