my cuisanart dgb300coffee maker grinder?

I found it. In the water feed hose in the botom of the unit, there is a check valve with a small plastic type ball. the ball sticks closed blocking the water from entering the heating coil,and telling the sensor it is done brewing,and then the 5 beeps.It's a fragile check valve.I suggest several cleanings with vinegar or similar. I hope i helped someone out .
