Model Cwtf 15 It keeps running. when pot is full

Normally that would be an easy fix if the water just continued to flow. You just replace the water inlet valve and they can stick open or partially open. But you say if you power off, the flow stops. That sounds like the control board is supplying residual power to it. Control boards are expensive so I would call for service. Or you can try some of the fixes here.

Renew the main thermostat.

You can take the lid off and unscrew the nut that holds the water tray. Then take a 3/8 hose to siphon the water out of the machine.

you'll have to recallibrate. use a 64 ounce measuring cup and follow the instructions on the inside of the front panel.

Could be something stuck in the brew valve or needs to be rebuilt.If not a possible bad brew timer.Rare that a brew switch is bad.

Which grommet, there are several on the bunn models, but the most commonly replaced one is the one for the P. stat. Remove the top panel there are 2 screws one in front and one in back, then lift the top 2 burners off machine that will give you access to the tank.

as far as I know, no i have one as well

There is a timer inside the front panel re-just the timer with an empty coffee pot right up to the top edge with water only.
if not successful let me know and I'll go further with your problem.my email address [email protected]
God Bless have a nice day.

If this problem started after moving the machine, pull the machine out a little & look behind it for a kink in the tubing coming to the brewer. These brewers time the water coming through them, so if a kink is restricting the water flow, running the same amount of time equals much less coffee in the airpot.
