Ariston Oven Error Code ER82

ER82 indicates a Key9 fault on the Ariston oven's touch control panel. The control system has detected an abnormal or continuous signal from the ninth touch button position on the display interface. This is most commonly caused by moisture on the panel surface but can also result from a hardware fault in the display board itself.

It is generally not advisable to continue using the oven while an active fault code is displayed. The ER82 code indicates the control panel is registering an unintended button input, which could cause unpredictable behavior in the oven's operation. Allow the panel to dry and clear the fault before resuming normal use.

If the issue is only moisture and resolves after drying, the repair costs nothing. If the inductive rubber inserts need to be sourced and replaced, costs are typically low. If the display board requires replacement, parts and labor combined can range from roughly 80 to 200 dollars or more depending on your region and whether a technician is needed.

In many cases, yes. The first step is to open the oven door and let the touch panel dry out completely, since condensation is the most common cause of this fault. You should also check that all small rubber inserts behind the touch surface are present and seated correctly. If the error clears after drying, no parts are needed.

A power reset may temporarily clear the code if the fault was caused by a transient moisture event that has since dried. However, if the underlying cause, such as a failed display board or a missing inductive rubber piece, has not been addressed, the ER82 code will return. Drying the panel or correcting the hardware issue is necessary for a lasting resolution.
