ROUBLESHOOTING

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.

TROUBLESHOOTING KEY

Find the symptom below that corresponds to the malfunction, then turn to the corresponding figure and page.
Follow the flowchart on that page until the problem is solved.
