Why is my Daikin EKHBRD-AY1 Heat Pump not heating properly even when it's on?

  amanda06Aug 12, 2025
  If your Daikin Heat Pump isn't heating as expected, even when turned on, there are several things you can check: * Ensure the temperature setting on the controller is correct. * Verify that all shut-off valves in the water circuit are fully open and clean the water filter if needed. * Purge any air from the system. * Check the manometer to confirm sufficient water pressure (greater than 0.3 bar when the water is cold, and significantly greater when hot). * Confirm the expansion vessel is not broken. * Also, ensure the water volume in the installation is above the required minimum. Finally, check if the cooling fans at the rear of the switch box are working properly.

  Kaitlyn FrostAug 25, 2025
  If your Daikin Heat Pump pump is making noise (cavitation), it could be due to air in the system. Try purging the air. Another cause might be low water pressure at the pump inlet. Check the manometer to ensure sufficient water pressure (greater than 0.3 bar when the water is cold, and significantly greater when hot). Also, verify the manometer and expansion vessel aren't broken and that the expansion vessel's pre-pressure setting is correct.

Why does the water pressure relief valve open on my Daikin Heat Pump?
- E
  Emily HurstAug 31, 2025
  If the water pressure relief valve on your Daikin Heat Pump opens, it could be because the expansion vessel is broken, in which case you should replace it. Alternatively, the water volume in the installation might be too high. Ensure the water volume is under the maximum allowed value.

What to do if the water pressure relief valve leaks in my Daikin EKHBRD-AY1?
- J
  joshuasmithSep 4, 2025
  If the water pressure relief valve on your Daikin Heat Pump leaks, it might be due to dirt blocking the valve outlet. Check the pressure relief valve by turning the red knob counter-clockwise. If you don't hear a clacking sound, the unit requires servicing. If water continues to run out, close both the water inlet and outlet shut-off valves.

Why does my Daikin Heat Pump display 'nnnn' when I press certain buttons?
- A
  Andre BellSep 8, 2025
  If your Daikin Heat Pump user interface displays "nnnn" when pressing certain buttons, the current permission level might be set too low to allow the use of that button. Change the "user permission level" field setting.
