A DHW sensor fault indicates a shorted or open Domestic Hot Water (DHW) temperature sensor. Check for shorted or mis-wired DHW sensor wiring, or a defective DHW sensor.
What causes a return sensor fault on an Alpine ALP080B?
A return sensor fault indicates a shorted or open return temperature sensor. This can be due to shorted or mis-wired return sensor wiring, or a defective return sensor.

Why is the system or boiler circulator not running on my Alpine ALP080B Boiler?
When there is a Domestic Hot Water Heat Request the System or Boiler pumps will be forced “off” when there “Run Pump for” parameter is set to “Central heat, off DHW demand” or “Central Heat, Optional Priority”. This setting allows all of the heat to be provided for fast indirect water heater recovery. After one hour of “priority protection” or the end of the Domestic Hot Water Heat Request the system and boiler pumps will be free to run. Also check the wiring for loose connection, miswiring.
How do I fix a flashing Zone Panel Setup on my Alpine ALP080B Boiler?

Why is my Alpine ALP080B Boiler display dark but the fan is running?
If the display is completely dark, but the fan is running, the issue is likely a lack of 24Vac power to the control. Check for loose 120Vac connection wiring between the boiler J-Box and the transformer, or loose 24 Vac connection wiring between the transformer and the control.
