What to do if the Internal Flow Switch is Open on my Aqua Comfort AC1050?
- E
  ecampbellAug 14, 2025
  If the internal flow switch on your Aqua Comfort Swimming Pool Heater is open, it could be due to several reasons. First, check that the pump is running and ensure there's sufficient water supply, looking for any air leaks. The filter might be dirty or clogged, so clean or replace it. Make sure that valves are correctly positioned and that the filter is not in backwash mode. An undersized pump can also cause this issue, so consider replacing it with an appropriately sized pump. Finally, the water pressure switch might need adjustment or replacement.

  If the low-pressure switch is open on your Aqua Comfort Swimming Pool Heater, several factors could be the cause. The evaporator coil might be dirty, so cleaning it is a good first step. Check if the fan motor is running; if not, repair or replace it. Low refrigerant pressure can also trigger this issue, so check the refrigerant levels and recharge if necessary. Finally, the low-pressure switch itself might be defective and require replacement.
