hi i've got a whirlpool adp 4500 wh dishwasher. started wash cycle m/c drained then green led started flashing on/off as drain pump turned on/off. i manually drained m/c now all it does is led flashes 11 times.
anyone know the error codes that relate to flashes?

It means optical water indicator failure (OWI). However not all versions of this model have one fitted, most have a regular pressure switch. Since there are several versions of this particular model it is impossible to tell if your machine has one or not. But...if the drain pump was pulsing on & off it sounds more like a pcb issue than anything else. Perhaps you ought to inspect the pcb for damage/blown triacs. Post the service number on the door sticker if you need more specific info.
