Trying to pin point why the 10.18ml is not heating up. Is there a reset button or an element that went bad. Or possibly a sensor of some kind??
With a combi oven, things are not quite that simple. Even with electric. Do you have any error codes. Something should have shown up. But it comes down to this, Power, safeties, Sensing, control, resistance. If the oven has power, The safeties are clear, and the sensors are telling the controller we need heat. And the controller suppy's power to the control contractors to power the resistance heaters you will now have heat. Providing that the heaters have continuity. So, If you understand what I have provided, Take your multi meter and find the problem. If you do not understand it or I lost you at some point, Hire in a Tech that does. Combi ovens are a sophisticated and sensitive product that requires a trained tech with the proper tools and updates to troubleshoot and repair They also have special programs, timers, and a source of steam that work together for a quality end product.
To help you further, I need to know what control panel and what power you are on.
I can only add...the manual. Pretty much the same one a technician would refer to for troubleshooting. The schematics are very clear, concise and easy to read:
