How to fix a noisy pump (cavitation) in my Daikin ERLA-DV17 Heat Pump?
- M
  Michael MarquezSep 7, 2025
  If the pump in your Daikin Heat Pump is making noise (cavitation), it could be due to air in the system. Purge the air manually or use the automatic air purge function. Another possible cause is that the water pressure at the pump inlet is too low. Ensure the water pressure is above 1 bar, the water pressure sensor is not broken, the expansion vessel is not broken, the valve of the water circuit towards the expansion vessel is open, and the pre-pressure setting of the expansion vessel is correct.

Why is my Daikin ERLA-DV17 Heat Pump not sufficiently heating at low outdoor temperatures?
- V
  vgreenAug 25, 2025
  If your Daikin Heat Pump isn't sufficiently heating the space at low outdoor temperatures, it could be due to several reasons: * The backup heater operation might not be activated. Ensure the backup heater operation mode is enabled. * The backup heater overcurrent circuit breaker might be off. Turn it back on if it is off. * The thermal protector of the backup heater might be activated. If it has, check the water pressure, whether there is air in the system, and the air purge operation, then press the reset button in the switch box. * The backup heater equilibrium temperature may not be configured correctly. Try increasing the equilibrium temperature to activate the backup heater operation at a higher outdoor temperature.

What to do if Daikin ERLA-DV17 fails?
- A
  Alexis DiazAug 26, 2025
  A Daikin Heat Pump failure can stem from several issues. It could be due to damage to the heat pump itself, in which case you should consult the help text for malfunctions. Another cause might be air trapped within the system, requiring you to purge the air. Also, an incorrect hydraulic balance could be the reason; the installer needs to perform hydraulic balancing to ensure correct flow distribution. Finally, various malfunctions can trigger a failure; check the user interface for error codes and consult the help text for malfunctions.

Why is the water at the tap too cold with my Daikin Heat Pump?
- G
  gloriatrevinoAug 27, 2025
  If the water at the tap is too cold when using your Daikin Heat Pump, it might be because you ran out of domestic hot water due to unusually high consumption. If you need hot water immediately, activate the DHW tank Powerful operation. Keep in mind that this will consume extra energy.

Why is the water pressure unusually high at the tapping point of my Daikin ERLA-DV17 Heat Pump?
- K
  Kayla HarrisSep 13, 2025
  If the pressure at the tapping point of your Daikin Heat Pump is temporarily unusually high, it could be due to a failing or blocked pressure relief valve. Flush and clean the complete tank, including the piping between the pressure relief valve and the cold water inlet, or replace the pressure relief valve.

What to do if Daikin ERLA-DV17 is not heating or cooling and water flow is low?
- C
  Christopher MartinSep 3, 2025
  If your Daikin Heat Pump isn't heating or cooling as expected, it might be due to low water flow. Ensure all shut-off valves of the water circuit are completely open, the water filter is clean, and there is no air in the system. Also, check that the water pressure is above 1 bar, the expansion vessel is not broken, and the valve towards the expansion vessel is open. Verify that the resistance in the water circuit isn't too high for the pump.
