What Does Error E90 Mean?

The Zanussi Washing Machine E90 error indicates a configuration or communication fault between the main PCB and the control/display interface PCB. This issue often prevents the machine from starting or completing a cycle, with the error persisting even after basic resets. It may also cause the machine to stop responding entirely, indicating potential loose, corroded, or faulty connections.

Common Symptoms:

  • Washing machine will not start or complete a cycle when E90 appears on display.
  • Repeated occurrence even after basic resets.
  • Machine stops responding and displays E90 consistently.

Possible Causes

  • Communication/configuration fault between main PCB and control/display interface PCB (high)
  • Loose, corroded or faulty connectors/cabling between control boards (medium)
  • Faulty electronic control board (main PCB or user interface PCB) (medium)

How to Fix Error E90

DIY Fix Basic reset and visual checks

  1. Disconnect the washing machine from power and wait at least 30 seconds.
  2. Reconnect and try restarting the machine to see if error persists.
  3. Ensure the machine is on a stable power supply to avoid surges.

Technician Only Inspect and repair internal electronic connections/boards

  1. Unplug the appliance and remove the access panel to reach control boards.
  2. Inspect connectors and cabling between main PCB and user interface board; reseat or replace if corroded or damaged.
  3. Test or replace faulty control board(s) if communication faults persist after connector inspection.

Parts needed: Main control PCB, Interface/control panel PCB, Connector cables

🛑 When to Call a Pro:
  • If basic resets and connection reseating does not clear the error.
  • If you are not comfortable accessing internal electronic components.
  • If there are signs of board damage (burn marks, corrosion) visible on inspection.
