Diagnostic steps

1. Turn off the alarm

   Press the START/STOP key to turn off the Er8 alarm once the message is displayed.

2. Note reduced steam function

   Understand that steam generator heating is deactivated while other generator functions stay active, so steam performance will be limited until repair.

3. Power down for service

   Switch the oven off at the upstream safety switch and let it cool before any internal work on the steam generator.

4. Call a qualified technician

   Have a qualified technician repair the damaged preheating temperature sensor in the steam generator, as the manual directs.

When to call a professional

Call a qualified technician for Er8, because the manual identifies a damaged steam generator preheating temperature sensor and instructs you to have a qualified technician repair it. Accessing and replacing a sensor inside the steam generator is service work involving the steam and water circuit, so it must be performed by trained personnel after the oven is isolated and cooled.
