1. Main power, (115VAC), must be present at the Hotline and Neutral terminals of the ll/drain timer.
2. Turning the machine ON/OFF switch ON, sends 115VAC to the "SW Power" terminals which
activates the initial ll.
3. The rinse valve is activated for 70-seconds.
4. The drain pump also operates for the same amount of time. This prevents any overow conditions
if the wash tank had not been drained previously.
5. If the door is opened during the ll cycle, then all functions are suspended and will continue from
where they left off once the door is closed.
6. To prevent false lls due to brief power interruptions, the following safety measures are built into the
operation of the Fill/Drain Timer:
a. Power must be present at the Hotline and Neutral terminals for 5-seconds
before the signal from turning the machine ON/OFF switch ON is accepted.
b. A ll will not happen unless the machine ON/OFF switch is OFF for 5-seconds
before being switched ON without interruption.
The Fill/Frain Timer provides both automatic ll and semi-automatic drain functions for the
dishwasher. It is located on the back of the electrical component panel and it operates as follows:
