cause a leak down onto the floor. Another leak possibility
is an missing or damaged "O" ring that fits over top of

RINSE AID DISPENSER
The Rinse Aid Dispenser has a circuit board located on
the dispenser to send a signal to the control board
display. When the rinse aid is low with Jet Dry, the board
will send a signal to the display window and will display
a "LO" which indicates that the customer needs to fill the
rinse aid dispenser back up with Jet Dry solution.
NOTE: The "LO" is only shown on the display during the
time the "Clean" light is on.
One way to check to see if you have a bad board when
there is no "LO" displaying is to turn off the power supply
(breaker) and pull off the two wires going to the small
circuit board and use a jumper wire to jump from one
wire to the other. Then, turn the power supply back on.
"PF" should start flashing in the display window. Now,
latch the door and the flashing "PF" should go out. This
is called the "Idle Mode". To go into the "Service Test
Mode", simultaneously press the HI-TEMP WASH &
START/CANCEL pads for 1.5 to 2 seconds. It should
display a 07 in the Display Window. Keep pushing the
START/CANCEL pad until it gets down to the clean
cycle. Here is where the LO should appear in the
display window. When this does come on,this indicates
that there is a defect in the small circuit board on the
detergent assembly. If ther is not a display of "LO", then
this indicates that there is a control board defect, or a
loose or broken wire. Check wires first for continuity. If
ok, replace Control Board.
WARNING: WHEN UNPLUGGING THE JUMPER
WIRE THAT YOU USED, MAKE SURE YOU TURN
OFF THE POWER SUPPLY FIRST, UNHOOK
THE TWO WIRES TO THE JUMPER, THEN
RECONNECT WIRE TO CIRCUIT BOARD.
RESTORE POWER.
