There could be a water scale buildup within the Steam & Grill Oven. This is caused by user filling the water tank with tap water instead of distilled water. Scale buildup would clog the internal water pipe. If you notice a slow or interrupted stream of steam, or if there are white powdery substances ejected together with the steam, you may try adding citric acid or white vinegar into the water tank and run the oven in order to clean up the scale buildup in the pipes.

If there is no steam coming out at all, it means the pipes are heavily clogged by water scale. Please contact a technician for a repair immediately. It is recommended that distilled or filtered water are to be used in the water tank. Also, please go through the above de-scale process every 1.5 to 2 months in order to prevent clogging.
