My sister had her p68 installed in dec of 2011. It shuts down during the night and the hopper is full. Her dealer has been to the house 3 different times. They changed the gasket on hopper, electric board, and fines cover. I haven't talked to her since they came out last Monday, so I don't know if it has happened since the fines cover has been changed. Anyone else have these problems. I bought my stove from the same place in January and it runs fine.
