On machines without displays, there was basically no concept of an error code: there the problem occurred corresponded to a certain combination of lit or blinking indicators.

Maintenance involves cleaning debris from the system:

  • Flush it out of the clog.
  • Check the operation of the inlet valve. Inspect its holes. Debris clogs the passage, making it difficult for the diaphragm to move. It does not open and no liquid is dispensed.

If there are problems with the drain, the pump is not necessarily broken. Check the parts for clogs:

  • Unscrew and clean the part.
  • Check the pump impeller. Pieces of food, penetrating through the filter, can block its rotation.
  • Remove water from the opening.
  • Remove the lid by pulling.
  • Wear gloves, remove the clog.
