I really love the dishwasher tablets instead of the squeeze stuff. I bought the big container of the Finish tablets at Costco. But about 1 out of 4 times.....they don't dissolve. Sometimes the little soap holder is still closed (not sure if that is supposed to open during the cycle? never noticed) and the tablet is all gloppy in the there. Other times, the holder is still closed, but the tablet has dissolved and the holder is empty. :confused Does anyone else have this problem?
