PROBLEM: WATER NOT FLOWING FROM SPRAYHEAD.
SOLUTION
POSSIBLECAUSE
Checkwaterlevelintank.Ifwaterisnotowingintothetank,re-
view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 N of the
timer. When the timer is activated by the brew switch, you should
read110to120voltsacrossterminalsNO and N of the timer. The
REDwireonterminalNO 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owsthroughthevalve,cleanoutthevalve
or replace the coil.
