What an ERROR XX Code Means on an Asko Microwave

An asko microwave error xx message on a built-in OM, OCM, or OCSM unit is a bare, undecoded problem display - Asko's own manuals give only one instruction for it, disconnect, reconnect, and call a technician if it returns, with no published table of specific numbered meanings.

An asko microwave error xx message on a built-in OM, OCM, or OCSM unit is a bare, undecoded problem display - Asko's own manuals give only one instruction for it, disconnect, reconnect, and call a technician if it returns, with no published table of specific numbered meanings.

A number appearing after the word ERROR on a control panel naturally looks like it should decode to something specific, but an asko microwave error xx display is exactly what it appears to be: a generic problem indicator, not a coded message with a documented meaning behind each number. Asko’s own manuals for built-in microwave and combi-microwave ovens give a single, consistent instruction for this display: disconnect the unit, reconnect it, and call a technician if the error returns.

Why there is no meaning table to consult

Various third-party repair sites publish tables claiming to decode specific ERR or ERROR numbers into precise problem meanings for Asko ovens and microwaves. None of those tables trace back to a confirmed primary Asko manual, and Asko’s own documentation does not include one – the asko microwave error xx display is intentionally left as a general problem flag that tells a technician to investigate rather than a self-diagnosing code an owner can look up and act on directly.

What generally causes the display to appear

Because the code itself carries no specific meaning, diagnosis has to work from symptoms surrounding the error rather than the number displayed. Common underlying causes across combi-microwave units generally include a door interlock switch not registering the door as fully closed, a control board failure, a magnetron or high-voltage circuit issue, or a temperature sensor reading outside its expected range during combi convection use.

Following the manual’s instruction correctly

The disconnect-and-reconnect step means fully removing power at the source – unplugging the unit or switching off its dedicated circuit breaker – rather than just cycling the control panel off and on, since a control-board reset needs a genuine power interruption to clear. Leave it unplugged for at least a full minute before restoring power, then run a normal cycle to see whether the asko microwave error xx display returns.

What it means if the error keeps coming back

An error that clears after a power reset but returns on the next few uses points toward a genuine underlying problem rather than a one-time glitch, and given the high-voltage components inside a built-in microwave, this is not a situation to keep resetting indefinitely – repeated resets do not fix an underlying hardware problem, they just delay finding it.

What to tell a technician when an asko microwave error xx appears

Rather than just reporting the number displayed, note whether the error appeared during a specific mode – plain microwave, combi convection, or steam on an OCSM unit – and whether it happened immediately on starting a cycle or partway through. This context does more diagnostic work than the number itself, since an asko microwave error xx that appears only in combi mode points differently than one that appears the moment the door is closed, even though both would show the identical generic display on the panel.

Why some owners report the display briefly showing a number before settling on ERROR XX

On certain control-board revisions, the display can briefly flash a number before an asko microwave error xx display settles into view, which some owners mistake for a more specific code before it disappears – this brief flash is part of the control board’s own internal diagnostic routine and is not a separate, hidden code meant for the owner to read and act on. Reporting exactly what you saw, including any number that flashed briefly before the ERROR XX display settled, is still useful information for a technician even though it is not something the manual documents as a standalone meaning.

How this differs from a smoke or burn smell accompanying the error

If an ERROR XX display appears alongside a burning smell, visible smoke, or unusual heat from the cabinet exterior, treat this as more urgent than a typical display failure – disconnect power immediately and do not attempt to run another cycle even briefly to see if the error clears, since this combination of symptoms points toward a more serious electrical problem than the error display alone.

Getting a persistent error diagnosed

If your built-in Asko microwave keeps returning an ERROR XX display after a proper power reset, our experienced, independent technicians can trace the underlying cause rather than guess from the number alone.
