Water not flowing into
the coffee brewer.
Water filter is clogged.
Grounded probe (78).
Water inlet valve coil
burned out.
Defective Liquid Level
Control board
(L.L.C.)(54).
SOLUTION
POSSIBLE CAUSE
Disconnect the water line from the inlet valve (31) and check to see
how much water pressure there is. Reconnect the water line.
Your filter cartridge may need replacing.
Whenever the water level in the tank drops below the probe tip, the
water inlet valve should open to fill the tank. If the water level is
too low, check to see if the probe is grounded. Pull wire terminal
off the terminal on the probe. If water flows into the tank, this
indicates that the probe has shorted somewhere. Locate the short
and correct it. Wrap probe wire with Teflon tape if there is an
indication of excessive condensation. Unscrew the probe and
polish it with sand paper. Leave 1/8" of tip exposed.
Turn off power to the brewer at the toggle switch, (45). Disconnect
wires at the inlet valve coil. Connect a lamp cord to the coil termi-
nals and plug into a 120V outlet. Water should flow out of valve. If
valve does not respond, clean out or replace valve.
If tests indicate that both the probe and water inlet valve are func-
tioning correctly but low water condition persists; check the opera-
tion of the liquid level control board.
Measure voltage at the input terminals T2 & T3 of the L.L.C.. Your
voltmeter should read approximately 115 volts. It should also read
115 volts at the output terminals T1 & T3 (this output supplies
power to the valve coil). Lacking voltage at T1 & T3 terminals will
indicate that the L.L.C. is malfunctioning. All wire connections to
the board should be tight. Make sure there is contact between the
grounding plate on the back side of the L.L.C. and it's mounting
bracket. If these tests check out and the board is still inoperative,
replace the L.L.C..
