Boiler type UFT-100W

Error code Er32

Cause:

DHW Sensor Short

Solution:

NOTE: This error will only appear if an aquastat is installed and SEnS is selected in Installer Mode 39, or a sensor is used and it is shorted. This Error Code will go away if an aquastat is installed, AquA is selected in Installer Mode 39, and the boiler is powered OFF and ON, or the DHW sensor is repaired or replaced.

- Check DHW sensor. If an aquastat, ensure AquA is selected in Installer Mode 39. If a sensor, ensure connections are secure.
- Check DHW sensor resistance. If resistance is zero, replace the sensor.
- After completing steps 1 and 2, power the boiler OFF. Then turn it back ON. - If the problem persists, replace the main control.
