Error codeE9 / E09
ApplianceDishwasher
Quick answer
E9 reads a button as held for more than 30 seconds. Dry and clear the panel.
Model compatibility: Bertazzoni reuses codes across series and model years, so E9 / E09 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
A button has been pressed for more than 30 seconds; water or something may be on the button.
What E9 means
E9 (E09 in some lists) appears when a button on the control panel has registered as pressed for more than 30 seconds.
What the manuals give as the reason
DW24XV: water or something may be on the button.
DW24PR and DW18PR: the button is sticking; the warning is resolved once the button is released.
Steps to try
Check the panel for water drops, dried detergent or any object on a button.
Wipe the panel with a soft cloth that is only damp, then dry it.
Start the machine again.
Wring the cloth well so no liquid runs behind the panel. Dried detergent or rinse aid near the buttons can keep one pressed, so let the panel dry completely before power is back on.
If it does not clear
When a button stays down, or E9 returns on a clean, dry panel, the manuals offer nothing further. Have a technician look at the panel and do not open the dishwasher yourself.
Which manual says what
The DW24XV manual points to water or something sitting on the button. The DW24PR and DW18PR manuals speak of a sticking button, and say the warning is resolved once the button is released.
