Arrived at location on 5/6/22 - Turned on steam and could not get to give error code. Was told can take 30-60 minutes to appear on screen. Removed the ignitor and checked the tank and found no water inside. Tank is in good condition. Believe the module relay is giving issue. Turned on again and allowed to steam for 25 minutes and the “reset gas” appeared. Will order new module and ignitor for the oven. Will return. Unit is in use with hot air only. Returned to location on 5/24/22 - Dissembled the unit and removed the module. Replace the module with a new one and went wire for wire to have it exactly the same as previous. Removed the ignitor and replaced it with a new one. Reassembled and tested oven in steam on “cont” for 15 minutes. Opened and close door and ran it for another 15 minutes. Unit is working good and ready to steam. Combi oven back in service.
