Timer
Part Number
32787
Function
Provides an automatic timing sequence of the wash, rinse, detergent and rinse aid injection
stages in a dishwashing cycle.
Description
The electromechanical timer has a main drive motor and gearbox which produce a full
rotation of the seven cams in 360 seconds. The advance motor and gearbox speed the
rotation of the timer to produce shorter cycles of 120 and 240 seconds. The timer cams
operate individual changeover switches in sequence during the rotation. The cams are
numbered from the main motor end. T1 controls the main motor, T2 – wash, T3 – rinse,
T4 – rapid advance motor for 120s cycle, T5 – rapid advance motor for 240s cycle, T6 –
detergent injector if fitted, T7 – may be used for electric rinse fluid injector if required.

Replacement
To replace the timer take note of the position of each connection, preferably on paper.
Disconnect all wires and remove the timer from the tray. Compare the cam setting of the
old and new timer to ensure that special settings are duplicated. Fit new timer taking care to
locate cam T1 in the same relative position. Reconnect the wires ensuring that no
termination is under strain. Test the machine to confirm correct operation.
Adjustment
The timer cams T2, T3, T6 and T7 are adjustable. The time settings on these cams can be
increased by making the gap in a cam wider, or reduced by reducing the gap. Use a timer
adjusting tool, supplied with the machine to modify a gap in the timer cams.
IMPORTANT
The factory setting of the cam T3 allows for a 15 sec hot rinse. Reduction of this
time is prohibited by Health regulations. Extending this setting will increase hot
water consumption of the machine and may result in delays between the cycles as
this additional water is heated.
