The drain valve in its normally
closed position should always
have 24Dcv_Rtn_L input along
with the +24Dcv_H out put
from the IFB J8 connector to
the motorized drain valve.
The drain valve opens when the
+24Dcv_H switches from J8-8
to J8-9 then it should switch
back to close.
The drain valve will only open
when the logic board sends an
output signal to the IFB after
oven is cold and 4-5 hours of
non use, or when the flush
switch is activated at the IFB.
