PROBLEM: WATER NOT FLOWING FROM SPRAYHEAD.
SOLUTION POSSIBLE CAUSE
Check water level in tank. If water is not flowing into the tank, review
steps 1 thru 4, previous page.
Check the continuity between terminals 5B and 4B when the BREW
switch is pressed. If there is no continuity, replace the switch.
Make sure the timer is receiving 110 to 120 volts. You can verify this
by taking a reading with your meter at the end of the YELLOW wire
on terminal 5B of the ON/OFF switch and at terminal A of the timer.
When the timer is activated by the brew switch, you should read
110 to 120 volts across terminals 6 and A of the timer. The RED
wire on terminal 6 supplies power to open the dump valve. If no
voltage is present, replace the timer.
If the timer works when the brew switch is pressed, then check the
dump valve using a voltmeter on the terminals. If it shows 110 to
120 volts but no water flows through the valve, clean out the valve or
replace the coil.
