My Europa 75 goes through the 15-30 min start up and then shut off, control board goes dark. I have check and cleaned everything. The only code it throws after waiting for cool down and trying again (because quick restart doesn't work if panel is dark) it goes throw the entire start up and and shut down control panel and all. I don't know what to try please help if any idea. Is there a high point sensor or a reset button I'm not finding?
