Hello

My Indesit dishwasher is displaying the F12 code.
After finishing one full wash cycle the dishwasher was turned off, after turning it back on when it was full the dishwasher did not power on.
After some time it displayed a F12 fault code on LCD display. when I tried to power it on/off or press any buttons but it did not do anything.
Can you help me with diagnosing the problem?
Thank you for help
