What Does Error E20 Mean?

The Breville coffee machine E20 error indicates a malfunction related to the steam pump, often caused by the water level probes failing to detect water in the steam boiler. Symptoms include the display of 'E20' on the interface, a non-activating steam function, and insufficient steam pressure. Cleaning the water level probes and ensuring the water reservoir is filled can help resolve the issue.

Common Symptoms:

  • Machine displays “E20” or “Error 20” on its interface
  • Steam function may not activate or boiler stays cold
  • Potential failure to build correct steam pressure or complete steam cycle

Possible Causes

  • Steam pump activation times out due to water level probe not detecting water (medium)
  • Dirty or scaled water level probes interfering with correct detection (medium)
