Regular Single/Twin/Treble Machine Error Codes

Error Codes Solution Guides:


Error codes in general refer to issues with the machine sensing the temperature probe for each tank. They can be broken down as follow:

  • ‘A1’ – Tank 1 probe disconnected.
  • ‘A2’ – Tank 1 probe short circuit.
  • ‘A3’ – Tank 2 probe disconnected.
  • ‘A4’ – Tank 2 probe short circuit.
  • ‘A5’ – Tank 3 probe disconnected.
  • ‘A6’ – Tank 3 probe short circuit.

These messages can sometimes be caused by a loose connection which may resolve itself. However if the message continues then the probe may need to be replaced.
