Spray arm
monitoring
The cleaning result depends on the wash water reaching all surfaces
and cavities of the wash load. To do this the wash water is distributed
throughout the wash cabinet by the rotation of the spray arms of the
machine, baskets and wash carts.
It is possible to monitor the rotation speed of the spray arms during a
program.
The rotation speed is determined using special magnetic spray
arms. The sensors of this machine cannot detect the magnetic spray
arms of older basket and wash cart models and therefore these
cannot be monitored.
If the rotation speed detected is not within a pre-set range, a warning
message is shown in the display. This allows e.g., blockages due to
loading errors or build-up of foam in the water circulation system to
be identified and dealt with promptly.
The rotation speed range depends on the area of application, the
program and the wash cart or basket used.
If the rotation speed falls short of or exceeds the required spray arm
speed, this does not necessitate cancellation of the program. In fact
the program will - as far as possible - be correctly completed.
In any case, in addition to the error message in the display, this will
also be appropriately documented in the process documentation.
