1.14.3 Service Required Errors
A SERVICE REQUIRED error alternating with YES displays on the computer. After YES is pressed the
alarm is silenced. The computer displays an error message from the list below three times with the
location of the error. Then the computer displays SYSTEM ERROR FIXED? YES/NO. If yes is chosen,
enter code 1111. If NO is chosen the system returns to cook mode for 15 minutes then redisplays error
until issue is fixed.
Pressing the MIB reset button during any filter function will generate a “SERVICE REQUIRED”
