Fault cause
Detergent supply container empty.
Suction lance defective, connection
cable defective
Alarm delay time tmax. (MAXIMUM
METERING TIME) set too short.
Concentration value for booster set
too high (time does not suffice for
metering)
Rinse aid container empty
Suction lance defective
Connection cable defective
Triac for activating "Meter detergent"
output defective.
Alarm delay time
(Detergent overmet. delay set too
short
Conductivity cell or connection cable
defective, incorrect connection.
Measuring sensor for rinsing water
temperature defective or incorrect
connection.
Measuring sensor for dry zone
temperature defective or incorrect
connection.
Real-time module defective
On-hook switch S1 in incorrect
position
Conductivity cell defective
Main board defective
EEPROM defective
No data exchange takes place
between the main and additional
circuit boards.
This alarm is displayed when the
water conductivity is > 10mS/cm in
automatic zero-point suppression.
This alarm is displayed as soon as
the washing tank, rinsing or dry zone
temperature fall below the permissible
minimum value (LO) and the delay
time for the alarm has expired
This alarm is displayed as soon as
the washing tank, rinsing or dry zone
temperature rise above the
permissible minimum value (HI) and
the delay time for the alarm has
expired
If when changing the detergent, the
conductivity value after the unit is
switched on is ≥ 1mS/cm
- 80 -
Remedy
Connect new container
Replace suction lance
Change alarm delay time
Change concentration for booster
function
Connect new container
Replace suction lance
Replace connection cable
Replace the main board
Change alarm delay time
Check connection, replace conductivity
cell if necessary.
Check connection, replace measuring
sensor if necessary
Check connection, replace measuring
sensor if necessary
Replace the main board
Correct switch position
Replace the cell
Replace the main board
Replace the main board
Check the plug-in connection
Drain washing tank if necessary and
refill with fresh water.
Change the temperature limit value,
change the alarm delay time if
necessary
Change the temperature limit values,
change the alarm delay time if
necessary
Acknowledge the confirmation prompt
by selecting YES or, where necessary,
switch between detergents and
confirm the change by selecting YES.
