During cooking, water is heated through a steam generation system and converted into fine steam, which is then released into the cooking cavity.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Together with convection heating, the steam is circulated throughout the oven chamber to create a balanced cooking environment. Steam helps maintain moisture and tenderness, while hot air circulation ensures heat is distributed evenly for consistent cooking results.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5605\" src=\"https:\/\/www.fujioh.com\/my\/wp-content\/uploads\/2026\/07\/built-in-steam-oven-dual-rack-cooking.jpg\" alt=\"Interior view of a combi-steam oven filled with steam, showing two racks of food cooking simultaneously: a whole fish on the top rack and a tray of dumplings on the bottom rack.\" width=\"512\" height=\"384\" \/><\/p>\n<p><span style=\"font-weight: 400;\">This combination allows <\/span><a href=\"https:\/\/www.fujioh.com\/my\/product\/73l-built-in-combi-steam-oven-with-dual-convection-fan\/\"><b>FUJIOH CookXpert FV-ML75<\/b><\/a><span style=\"font-weight: 400;\"> combi steam oven to handle a wide range of cooking methods, from steaming vegetables and fish to baking bread and roasting meat, while helping food retain its desired texture and moisture.\u00a0<\/span><\/p>\n<h2><b>Water Supply Requirement: Tank vs External Plumbing\u00a0<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">There are two common ways combi steam ovens receive water: a tank-based system or a direct-plumbed system. The better choice depends on your kitchen setup, cooking frequency, and installation preferences.<\/span><\/p>\n<h3><b>Tank-Based Systems (Most Popular for Homes)<\/b><\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5609\" src=\"https:\/\/www.fujioh.com\/my\/wp-content\/uploads\/2026\/07\/steam-oven-water-tank-reservoir.jpg\" alt=\"Close-up of a modern built-in steam oven showing the blue water reservoir slightly pulled out from the control panel area above the door.\" width=\"512\" height=\"384\" \/><\/p>\n<p><span style=\"font-weight: 400;\">Many residential combi steam ovens use a detachable water tank that can be manually refilled before cooking.

Simple care routines can help protect the steam system and extend the appliance\u2019s lifespan.\u00a0<\/span><\/p>\n<h3><b>Use Suitable Water for Steam Generation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Water quality can affect long-term steam oven performance. In areas with harder water, minerals may accumulate over time and affect steam generation. Using filtered water where recommended and following manufacturer\u2019s water guidelines can help reduce mineral buildup.<\/span><\/p>\n<h3><b>Perform Regular Descaling<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Over time, minerals from water can accumulate inside the steam system, especially in areas with harder water. These deposits may affect steam generation performance and reduce cooking consistency. Regular descaling helps remove mineral buildup from the internal steam system, allowing the oven to continue producing steam effectively. Following the recommended descaling procedure helps maintain long-term performance and keeps the steam function working efficiently.<\/span><\/p>\n<h3><b>Wiping Down After Use<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">After cooking, a quick wipe of the oven interior and emptying any remaining water from the tank water when needed.
