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 fluorine.

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 specific 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.

Move this hose to front of machine near pressure gauge.

Remove this connector.

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.

60

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 fill/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.
