Superba Selectra 21, error code "8"

After power outage (when power come back on), constant high pitched tone is generated and “8” is displayed in status monitor. Sometimes I can get machine to reset by turning breaker off/on several times. It has been “stuck” in error mode for weeks, and I cannot get machine to reset. What does code “8” indicate, and what might be fix?
Thanks, Mark

Mark,

I’m afraid it is time for a new dishwasher because all parts inside the control panel as well as the control panel itself are no longer available.
