Query: Stops Working for No Apparent Reason

Great product until it unexpectedly stops working. Apparently this is a well known and documented problem. Surprised Krups hasn't found a fix. Tried to have it repaired but the estimate came to $72.98 not including the postage to get it to the repair center. Feel guilty wasting all of that cast iron, I hope the repair center melts it down for recycling.
