My Frigidaire dishwasher (model FFBD2411NS) stopped working today in the middle of a cycle, lights blinking (heavy load light, hot water light, heat dry light, sanitize light, and one phase light (wash): lights corresponding to the options I picked). It is an old model, without fancy displays or even a place for error codes.
I tried to restart the machine. It drained residual water and restarted a cycle, only to break down again a few minutes later. Most of the time, I can't even get the machine to restart, as the lights come blinking as soon as I hit the start button. I have tried different option combinations, but nothing seems to work. It seems sheer luck to get the thing to start. If I try again after 10 minutes, I might be lucky enough to get it to run a short while, but eventually it breaks down. It has been running fine for a year. Just yesterday it was working perfectly fine.
What could be the possible issue here? Any possibility this could be fixed without having to change parts?
