Have Model CTF-15. Only dripping half a pot. Has been slowly getting worse. Unit is over 5 years old. Gets moderate use .. one to two pots a day. Has dedicated water line. Starts just fine but runs out of water before pot is full.

Most of these have a control board that times the fill solenoid. On mine it is behind the main burner (you have to take 4 screws out).
instructions are on the back of the panel you remove.
CAUTION DO NOT TOUCH THE EXPOSED ELECTRICAL CONNECTIONS!
There's a small switch on the circuit board that has "lock" & "set" positions. Place the switch to SET, then press and hold the BREW switch until you hear 3 clicks. Release the BREW switch and press it again immediately. Each time you press the switch adds one second to the fill timer. I recommend you add about 5 seconds at a time, then allow the pot to finish filling (don't forget to have your filter funnel installed) when you are satisfied with the final level, place the small switch back to the lock position and reinstall the panel.

Change the in line water filter on the unit.
Unit may also need descaling.
