Noticed water on lower overlay. Next day unit display was 15 ,overlay issue. Placed overlay and cover in bag of rice for 2 days. When reinstalled unit failed to boot up. Stops cycle, lights flash and buzzer buzzes. No code on diagnostic screen. What is best advice? Send both boards and overlay to have tested? What is necessary to connect to diagnostic port in order to have it pinpoint issue? Is it possible to update firmware if parts are sent to your shop?
