properly, as noted above, there is a 15 second delay before it can
be attempted again.

(without diagnostic modes running).

DIAGNOSTIC TEST

The washer has two different modes of diagnostics:
The Manual Key Functions in Diagnostic Sub-Modes allows
running of diagnostic cycle. This allows a more thorough analysis
of washer operation, running of a Quick Drain and Spin, and
crediting of free cycles to the user. A Washer Cleanout Cycle may
also be run from this mode.
The Help Mode allows you to verify the help codes that are
currently present on the washer, and to check the software revision
of the CCU and UIC. It also gives feedback of the current state
of the valves, actuators, sensors, and general state of the washer.
