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 deliming 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 googles 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.

All S/N's have a new ll/drain timer, P/N 2103.43. 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 ll/drain timer is to ll the machine at the beginning of the day and to drain the machine at the end of the day. Normal wash and nal rinse cycles are controlled by the mechanical

cam timer assembly.

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

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 ll/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 ll/drain

timer mounting screws (C) and remove them.

Fill/DrainTimerBoard-TheoryofOperation

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

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

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/ll 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 ll cycle because the drain pump also runs during

the ll 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 ll cycle because the drain pump also runs during

every 70 second ll cycle.
