TROUBLESHOOTING
This section contains a troubleshooting key and referenced flowcharts to assist a qualified service technician
in the servicing of an SEZ Series Countertop Steamer. Please note that the unit has a “SERVICE
REQUEST” light that illuminates in the event of certain water supply problems. Also note that when
the unit is turned on, there is a four-minute time delay before the heating elements come on to allow
time for filling. Therefore, some procedures call for a waiting period when reconnecting power to the
unit or turning the unit on.
