Ariston Oven Error Code ER80

ER80 indicates a Key7 fault on the oven's touch control panel. The control system has detected a malfunction at one specific touch input zone, which can be caused by moisture, a missing or damaged inductive rubber piece, or a failed display board. The oven flags this code to alert you that the touch interface is not operating correctly at that position.

The ER80 fault relates specifically to the touch control input and may prevent the oven from accepting commands normally or operating at all. It is best not to attempt to bypass the fault and continue using the oven, as a malfunctioning control panel can lead to unpredictable behavior. Address the fault before resuming regular use.

If only an inductive rubber piece needs to be replaced, the cost is typically low, generally in the range of a few dollars to around $20 for the part, plus any labor. If the display board has failed, expect parts costs in the range of $80 to $250 or more depending on the model, with additional labor charges if a technician performs the repair. Getting a diagnostic visit from a qualified technician can help confirm which component is at fault before purchasing parts.

Yes, in many cases you can. Start by opening the oven door and allowing any condensation inside the touch panel to dry out completely before checking again. If the error clears after drying, no repair is needed. If it persists, check that all inductive rubber pieces behind the touch panel are present and properly positioned before concluding a board replacement is necessary.

A power reset alone is unlikely to permanently clear ER80 if there is an underlying hardware issue. The fault may disappear temporarily after cycling power, but it will return if moisture is still present or if the display board or rubber contact component is defective. The root cause must be addressed to keep the error from reappearing.
