PROBLEM
PROBABLE CAUSE REMEDY
Check plumbing and shut-off
valves
Check tank drain clamp
Direction of fl ow arrow must be
pointing towards direction of water
fl ow.
Remove the strainer and check for
obstructions. Clear or replace.
Check the sensitivity setting. Refer
to the REFILL function on page
40. If the left three digit number
is less than the right number, the
machine “thinks” it is full and the
refi ll valve should be off. If the left
number is larger than the right, then
the refi ll valve will automatically be
turned on to fi ll the tank. The right
number is the threshold setting and
can be adjusted to compensate for
extreme water conditions: very pure,
low conductance water requires a
higher setting, while high mineral
content, high conductance water
requires a lower setting. Note that
the left number changes from a high
value when water is NOT touching
the refi ll probe to a low valve when
water IS touching the probe. For best
operation, the right number should
be set to a value midway between
these low and high numbers. Be-
fore changing the setting, confi rm
that the refi ll probe is free of scale
buildup and the connection to it is
secure. Test the refi ll valve. Refer
to the test outputs procedures on
page 48.
