clicking noices and spitting hot water into reservior

I have had four separate brand new machines make one cup of coffee and then fail to make additional cups of coffee. The machine will make a series of clicking noises and then "spit" hot water into the reservoir. After multiple attempts to get the machine to reset the Add Water/Heating/Medium cup lights begin flashing. What can be causing this and how to I get the machine operational? Another replacement from Keurig is not the answer.
