We have a GE Dishwasher (GSD5560G00SS) that keeps beeping and flashing the drying cylce light.  It will not continue with the cycle of wash after start.  It will usually take approximately 5-7 min before it errors out.  We have it to wash on normal cycle with heated dry.  The owners manual says to reset and try again, if it repeats, call a service technician.  Anyone have any ideas or similar problems?
Locate the service sheet tucked in below the tub. They will give a specific reset proceedure there.
