Test programmes
Various programmes are available for monitoring cleaning perform-
ance in routine testing. The test programmes are not separate pro-
cessing programmes. Rather, they are additional functions that can
be activated prior to starting any processing programme.
The test programmes interrupt the programme sequence automatic-
ally at specified points. The interruption is indicated by an audible
signal tone and message on the display. The W&H Customer Service
Department can set the duration of the interruption to between
10 seconds and approx. 42 minutes. During this time period, meas-
urements can be made or the door can be opened to obtain a
sample.
To prevent cooling of the wash chamber, do not keep the door open
too long.
After the time period elapses, the programme sequence continues
automatically. If the door has been opened, the programme cannot
resume until the door has been closed again.
If a measurement or sample is not needed, you can resume the pro-
gramme sooner by pressing the Start/Stop button.
In addition, the door can be opened at any time during the drying
phase to check the dryness of the wash load. In this way, you can
determine the optimal drying time.
The following test programmes can be selected:
Laboratory
–
The programme sequence can be paused in each wash block im-
mediately before the wash fluid is drained away.
Validation
–
The programme sequence is interrupted at the following points:
– before the wash fluid is drained away in the final wash block,
– after the interim rinse before the wash fluid is drained away, and
– after water intake and before draining in the final rinse block.
