Wehave a bunn 3wtf15,3L SF, and after five years, all of a sudden the cycle only fills the pot about 2/3. C an you please send me a solution to raise water level?

Before changing the setting,  check the water inlet line, strainer flow control  and filtration system.  This is usually the cause of variation in pot fill.  Also mineral build up in the brew line. .Has it been cleaned and snaked with the cleaning spring recently.  The brewer also has to be level or slightly down in front for the siphon system to work correctly,. 

After you do that, then think about changing the volume timer.

 

NOTE: Check that the brewer is connected to water supply, the tank is properly filled, and a funnel and server or decanter are in place, prior to setting or modifying batch sizes. 1. Modifying batch sizes. To modify a batch volume, first check that the SET/LOCK switch is in the “SET” posi- tion on the circuit board. If the brewer has a batch selector switch, position it to the size to be changed. To increase a batch size, Press and hold the START or BREW switch until three clicks are heard. Release the switch (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory) and press it again one or more times. Each time the switch is pressed, two seconds are added to the brew time period. Allow the brew cycle to finish in order to verify that the desired volume has been achieved. To decrease a batch size, Press and release the START or BREW switch once for every two-second interval to be removed from the total brew time period; then immediately press and hold down the START or BREW switch until three clicks are heard. Release the switch. (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). Allow the brew cycle to finish in order to verify that the desired volume has been achieved. 2. Setting batch sizes. To set a batch volume, first check that the SET/LOCK switch is in the “SET” position on the circuit board. Press and hold the START or BREW switch until three distinct clicks are heard (this will take approximately ten seconds), and then release the switch. (Failure to release the switch within two seconds after the third click causes the volume setting to be aborted and previous volume setting will remain in memory). View the level of the liquid being dispensed. When the desired level is reached, turn the ON/OFF switch to “OFF”. The brewer remembers this volume and will continue to brew batches of this size until the volume setting procedure is repeated. Empty server(s), turn selector switch to positions that have yet to be set, and repeat batch setting procedure until all batch sizes are set. NOTE: When brewing coffee, batch volumes will decrease due to absorption by the coffee grounds. 3. Setting programming disable feature. If it becomes necessary to prevent anyone from changing brew times once programmed, you can set the SET/LOCK switch to the “LOCK” position. This will prevent any programming to be done. NOTE: If the clicks can not be heard, lightly grip the incoming water line to feel when the valve cycles on
