I would think that your dough was probably too wet. I test mine when it is kneading.
After 10 seconds of kneading when the TMX stopped I press the dough through the hole in the lid - your fingers should come out clean, if there is dough on there then add a little more flour.
There is a discussion somewhere on here with that tip from Quirky Jo (I think) - I will try and find it for you.
