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 an eight-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.
