What to do if the Daikin EGSQH10S18AA9W Heat Pump unit is NOT heating?
- DDarrell MerrittAug 12, 2025
If your Daikin Heat Pump isn't heating, it could be due to several reasons. First, if the water temperature is too low, the unit uses a backup heater to reach 15°C. Ensure the power supply to the backup heater is correctly wired, the thermal protector isn't activated, and the contactors aren't broken. If the preferential kWh rate power supply settings and electrical connections do NOT match, check the connections. If the electricity company sent a preferential kWh rate signal, wait for the power to return (2 hours max.). If problems persist after these checks, consider contacting your dealer.
