Fill Rate Adjustment
The fill rate depends on the water line pressure and the
opening of the FAST FILL VALVE, see figure 8. If the urn
does not refill as fast as it uses water during a brew cycle, you
may adjust the fill rate. If you adjust for maximum fill rate and
the level still cannot keep up, either the pressure is too low or
the fill system may have a clog. See Troubleshooting.

Figure 8, Fill Rate Valve
The level in the liner should be one inch below the line where the
liner ring attaches to the liner wall.
Re-adjust until the level is correct.
Remove the control access cover.
Locate the needle valve labeled, FAST FILL VALVE.
Open the valve a few turns.
Brew water into both liners simultaneously. Watch the
FILLING indicator.
If the light cycles on and off, the rate is fast enough.
If the FILLING light stays on, the rate is too slow. Re-adjust.
