Troubleshooting
• Connect or replace temperature sensor of
heating element 1 (connected to left heating
control circuit board with address 1 assigned)
• Connect or replace temperature sensor of
heating element 2 (connected to right heating
control circuit board with address 2 assigned)
• Connect or replace temperature sensors of
both heating elements 1 and 2
• Connect or replace temperature sensor of
medium in container (connected to central
control circuit board DIMA220)
• Connect or replace both the temperature
sensor of the medium and the temperature
sensor of heating element 1
• Connect or replace both the temperature
sensor of the medium and the temperature
sensor of heating element 2
• Connect or replace both the temperature
sensor of the medium and the temperature
sensors of both heating elements (1+2)
Fault description
Depending on the fault code, either one or
several temperature sensors are not connected
or have an open cable break.
The numerical code 199 in the second line of
the message indicates which temperature
sensor is defective.
