Service Test Load Control and Service Cycle Modes
Test Load Selection Procedure
To select Load or Service Diagnostics, use the Soil Level and
Temp buttons or cycle selection knob, if available. Soil Level
will increment through the loads and Temp will decrement
through the available functions.
Rotating the cycle selection knob clockwise will increment
the selected function while rotating counterclockwise will
decrement through the available functions.
Load Control Status Indication
The Estimated Time Remaining (ETR) display will indicate
the current selected load or function. If the selected load is
currently active (commanded on), the ETR display will flash the
load number at a 1Hz rate. If the load is currently commanded
off, the ETR display will show the load number without
flashing.
Commanding Loads 'On' and 'Off' in Service Test
Mode
With the desired load's number on the ETR isplay, the load can
be toggled on and off by pressing the START button. Each press
will toggle the state of the load from 'off' to 'on' or from 'on' to
'off'. NOTE: Activating any of the spin or agitate functions will
result in functions 10–14 reporting their status as 'on' because
reported status is based on motor motion being commanded.
Failure to Turn Load On Indication
If the number of loads (pumps, valves, and motor) allowed on
at the same time or the conditions to actuate the load are not
correct, the display will turn off momentarily and an invalid
tone will sound.
