114
Cooling of disinfected final rinse water is impossible.
Target temperature of disinfected final rinse water cannot be attained.
Program recognition
Error code 114
121
Level sensor is defective or not connected.
If level sensor (P 1) is disconnected for more than 2 seconds or is not connected (value
must be in range from 0.2 to 4.5 V), control system will shut down running program under
error indication.
Monitoring limit values input P1 during program cycle.
No water
Error code 121
122
Pressure sensor on pneumatic block PL is defective or is not connected.
If pressure sensor defective for more than 10 seconds or is not connected (value must be in
range of 0,2- 4.5 V), control system will cut running program off under error indication.
Monitoring of limit value input PL during program cycle.
Endo protection
Error code 122
123
Pressure sensor on pneumatic block PR is defective or is not connected.
If pressure sensor is defective for more than 10 seconds or not connected (value must be in
range of 02- 4.5 V), control system will break off running program under error indication.
Monitoring of limit value input PR during program cycle
Endo protection
Error code 123
130
Temperature sensor in wash chamber is defective or is not connected.
If temperature sensor NTC 1 for wash chamber is defective or is not connected (value must
be in range of 0 to 150 °C), control system will shut current program down under error indi-
cation.
Monitoring of limit value input NTC 1 during program cycle.
Cause:
Remedy:
If in analysis T 1 == sensor defective
Fix wire interrupt, replace sensor
