What it is

The Vaillant 0020233814 is an installer PCB for the Arotherm PLUS range of air source heat pumps. It is the three-phase (3Ph) variant of the installer board, used within the appliance's control circuitry. It is supplied as a board only.

Signs this part needs replacing

  • The heat pump fails to power up, or the display and controls stay blank.
  • Control-board fault codes appear and cannot be cleared.
  • The appliance runs intermittently or shuts down with no obvious external cause.
  • Visible damage on the board, such as scorching, burnt tracks or swollen components.
  • Settings or parameters are repeatedly lost after a power cycle.

Before you order

  • Confirm the appliance model and serial number against the manufacturer's parts list.
  • Check the part number printed on the existing board matches 0020233814.
  • Confirm the installation is three-phase, as this is the 3Ph variant of the board.
  • Board replacement should be carried out by a competent heating engineer with the appliance isolated.
