Flavia S350 Coffee Brewer Error Code 303 – Water Overflow

An error 303 on the display of your FLAVIA beverage system indicates a water overflow issue.  The Flavia brewer was probably moved or bumped with a full water tank triggering the over full sensor.  This can also occur if a brewer that is plumbed to a water line is then manually filled through the pour-over area.

In most cases this can be fixed very easily.

1. First turn off the machine.

2. Next drain about 1 quart of water from the tank using the left side drain hose behind the main door.

3. If this is a plumbed Flavia machine & there is water in the right drain hose behind the main door, drain that hose completely.

4. Replace drain hoses and turn the machine back on.  Allow it to refill normally.
