2. Refill probe or Sensitivity set-

Remove the strainer and check for

obstructions. Clear or replace.

 

 

3. Refill valve

Check the sensitivity setting. Refer

 

 

 

 

to the REFILL function on page

 

 

 

 

27. If the left three digit number

 

 

 

 

is less than the right number, the

 

 

 

 

machine “thinks” it is full and the

 

 

 

 

refill valve should be off. If the left

 

 

 

 

number is larger than the right, then

 

 

 

 

the refill valve will automatically be

 

 

 

 

turned on to fill 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 refill 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 num-

 

 

 

 

bers. Before changing the setting,

 

 

 

 

confirm that the refill probe is free

 

 

 

 

of scale buildup and the connection

 

 

 

 

to it is secure. Test the refill valve.

 

 

 

 

Refer to the test outputs procedures
