VACUUM_ON_ERR
Vacuum switch failed to close in time – occurs
whenever the vacuum pump fails to turn on properly,
usually at the start of a program, but also during a full
self-test sequence.
The switch is normally open. When the switch senses
the vacuum, it will close. Whenever the software turns
on the vacuum pump, the software will monitor the
vacuum switch until it closes, or until the vacuum
startup delay expires.
Probable Causes:
• Q-cups are defective or not properly connected.
• No vacuum source, external pump fuse has
blown, or external pump is defective and unable
to reach minimum vacuum requirements of 1.6”
HG.
• Vacuum source has not reached 1.6” HG.
• Waste bottle cap or caps are loose.
• Vacuum switch has failed in the open state.

WASTE_FULL_ERR
Waste switch detects a full waste bottle – occurs at the
start of a program (including
AUTOCLEAN
programs in
Ultrasonic Advantage™ models). The switch is normally
closed and when the waste bottle is full, the switch will
open.
Probable Causes:
• Waste switch is stuck or always in the open
state.
• Waste bottle is full.
• Foam in the overflow bottle has pushed the
switch open.
• Waste tubing is not properly connected, and the
overflow bottle is the primary bottle, i.e., the
first bottle that waste flows into.
