What do the flashing end indicator codes mean on the Rengora dishwasher?

The end indicator flashes intermittently to signal specific malfunctions: 1 flash means the appliance is not filling with water, 2 flashes mean the appliance is not draining water, and 3 flashes mean the anti-flood device has been triggered. An acoustic signal will also sound the corresponding number of times alongside the flashing indicator. (Page 15-16)
