Q&A
1. Why is the ADD WATER indicator on even though I've added water?
The water tank may not be properly installed. Push the water tank firmly into place and restart.

This may indicate a sensor error. Please contact customer service or a technician for repair.

It indicates the machine is in protection mode. It will resume working in about 1 hour. If this happens frequently, please run the self-cleaning program.
