1.14.3 Service Required Errors<br />
A SERVICE REQUIRED error alternating with YES displays on the computer. After YES is pressed the<br />
alarm is silenced. The computer displays an error message from the list below three times with the<br />
location of the error. Then the computer displays SYSTEM ERROR FIXED? YES/NO. If yes is chosen,<br />
enter code 1111. If NO is chosen the system returns to cook mode for 15 minutes then redisplays error<br />
