Owned another unit for 7 years and it was Great. Never had any issues. Told everyone how great the fresh ground coffee tasted. Water tank finally started to leak. Bought This as a replacement since I was so pleased w first unit. The new unit has issues w grinding the beans and the chute not opening so the coffee goes into the filter.  Works sometimes and not others. Everything has been properly cleaned. Never had this problem w first unit in 7 years. Preparing now to contact Customer Service for warranty on current unit. Works ok w ground coffee,but I bought this unit to grind the beans.
