Found Steamer unit with #1 float error. Cleaned float but calcium build-up is heavy and will not clean off completely. Energized unit and checked operation. Unit goes into float error when shutting down. Will need floats and relay board replaced. 11-14-18 Removed the faulty floats and relay board. I installed proper connectors on the new floats and completed the installation. I checked operation and the unit is working fine at this time.
