all wares are sanitized. If for any reason, the hot water temperature in the booster tank cannot provide this
temperature, the dishwasher will enter a Rinse Sentry Mode of operation and extend the cycle time.

(continued)

The Rinse Sentry changes the Normal Operation Mode as described below:

1. The Rinse Sentry constantly monitors the water temperature inside nal rinse booster.

2. If the temperature inside the booster heater falls below 180ºF/82ºC then the Rinse Sentry
will extend the wash cycle time until the booster heater water temperature reaches the proper
temperature.

3. The in-cycle light will remain illuminated during the Rinse Sentry Mode.

4. The RINSE water temperature gauge must be monitored to ensure a minimum of
180ºF/82ºC is maintained during the rinse cycle.

5. The temperature range for the final rinse water is 180-195ºF/82-91ºC.

Cleaning and Maintenance

De-liming

Minerals accumulate on the interior surfaces of the dishwasher. The deposits have a white haze
and, in cases of heavy accumulation, may appear as a granular solid. The generic name for mineral
deposits is lime. The removal of lime deposits is called de-liming. Your dishwasher should be de­limed regularly; how often will depend on the mineral content of your water.

Inspect your machine interior for lime deposits. If de-liming is required, a de-liming agent should be
used for best results in accordance with the chemical supplier's instructions.

Danger:

Death or serious injury may result when de-liming solution is mixed with sodium hypochlorite
(chlorine bleach) sanitizing agent. Mixing may cause hazardous gases to form.

De-liming solution and other acids must never be mixed with chlorine, iodine, bromine, or uorine.

Caution:

Skin contact with de-liming solutions can cause severe irritation and possible chemical burns.
Always wear protective clothing and goggles when handling chemicals.

Attention:

Contact your chemical supplier for specic safety procedures and instructions for the use of
the de-liming solution supplied for the dishwasher.

De-liming solution or other chemicals are not supplied by the dishwasher manufacturer.

Service Parts Installation - Booster Thermostat P/N 109069

Beginning with S/N W120330086, the booster control thermostat, P/N 109069 replaced the
existing thermostat, P/N 0512108 (identified by its white housing). On machines built prior
to S/N W12033086, the old thermostat can be replaced with the P/N 109069 if necessary.

Refer to the photographs below and on the next page for installation instructions.

Service Parts Installation - Pressure Gauge Piping Change

Beginning with S/N W120631515, the pressure gauge tubing has been relocated
from the top right rear corner of the machine to the booster located on the base
of the machine. This change improves the operation of the final rinse pressure gauge.

Refer to the illustrations below and on the next page for installation instructions.

Remove this connector.

Move this hose
to front of
machine near
pressure gauge.

Install this plug
where the connector
was removed.

Parts list is located on
pages 30-31.

Service Parts Installation - Fill/Drain TImer Conversion - P/N 0713133

Fill/Drain Timer Conversion - P/N 0713133

All S/N's for the 351HT have a new fill/drain timer, P/N 0713133. This new timer is slightly
larger than previous timers but it still mounts in the same location as previous timers.

The only function of the fill/drain timer is to fill the machine at the beginning of the day and to drain the
machine at the end of the day. Normal wash and final rinse cycles are controlled by the mechanical
cam timer assembly.

Refer to the illustrations below and on the following pages for installation instructions.

Service Parts Installation - Fill/Drain Timer Conversion - P/N 0713133

If your machine has the Cam Timer
with black cams, then the board
mounting screws can be accessed
without removing the timer drive motor.

If your machine has white and gray
timer cams (A), then it may be
necessary to remove the timer drive
motor to access one of the fill/drain
timer mounting screws (B).

To remove the timer drive
motor (A), remove the two
phillips screws and drop the
timer drive motor out of the way.

With the drive motor removed,
you can access the fill/drain
timer mounting screws (C) and
remove them.

Fill/Drain Timer -Theory of Operation

Fill/Drain Timer Board - Theory of Operation

LED's 1, 2, and 3 are illuminated
during a normal wash/rinse cycle.

1. The new ll/drain timer board has built-in diagnostics.

2. LED's (1, 2, 3, and 4) illuminate under the following conditions:

a) LED 1 illuminates when power from circuit breaker is ON and booster/fill
switch (service switch) is ON.
b) LED 2 illuminates when machine ON/OFF switch is ON and circuit breaker in ON.
c) LED 3 (Door switch LED) illuminates when door is closed, machine ON/OFF switch is
ON and circuit breaker in ON. LED 3 goes out when door is open.
d) LED 4 only illuminates momentarily when the drain switch is pressed and the machine
ON/OFF switch is OFF.
e) LED 5 (Drain LED) illuminates when the Power from the circuit breaker is ON, the
machine ON/OFF switch is OFF, and the momentary drain switch has been pressed to
start the 50 second drain cycle. The door can be opened during the drain cycle,
closing the door resumes the drain cycle where it left off.

NOTE: LED 5 will illuminate during the fill cycle because the drain pump also runs during
the fill cycle.

f) LED 6 (Fill Valve LED) illuminates when the circuit breaker is ON, the machine
ON/OFF switch is ON (3 second delay), and the door is closed.

NOTE: LED 5 will illuminate during the fill cycle because the drain pump also runs during
every 70 second fill cycle.
