What do the flashing display lights mean on my GSD4500 and what should I do?

Flashing lights accompanied by a beeping sound can indicate either a normal reset or a control error. If the START/RESET pad has been pressed, flashing is normal — allow the dishwasher to drain and reset before starting a new cycle. If the CLEAN light flashes with a beeping sound indicating a control error, press START/RESET to turn off the beeper; if it continues, call for service. (Page 6)
