Error code
Microwave signal ERROR XX
Asko microwave — reported by blinking lights rather than by a code. The same generic line as the ovens, printed word for word in four microwave manuals — OM8334S, OT8687S, OP8664A and OCM8456S.
- From $95 diagnostic, credited to the repair
- 59 cities and neighborhoods covered
- OEM parts available on order
- In writing the price, before anything is opened
What we can confirm
Signal ERROR XX, from the manufacturer's own documentation
This code has no number, because this equipment has no display to put one on. The appliance signals it instead — an alarm, a symbol or a pattern of lights — and what it means is recorded in the documentation that ships with it.
The signal
ERROR XX
The same generic line as the ovens, printed word for word in four microwave manuals — OM8334S, OT8687S, OP8664A and OCM8456S. Each of them says to disconnect from the mains for a few minutes, reconnect and reset the clock, and to call a technician if it persists. The XX is never decoded. What actually goes wrong on these cavities is far more ordinary than the message suggests: the three door interlocks in series, which are wear parts and stop the machine dead when one of them disagrees.

What it narrows down to
An error code is displayed and the manual never says what the digits mean.

About Microwave signal ERROR XX
What the appliance is actually reporting
The same generic line as the ovens, printed word for word in four microwave manuals — OM8334S, OT8687S, OP8664A and OCM8456S. Each of them says to disconnect from the mains for a few minutes, reconnect and reset the clock, and to call a technician if it persists. The XX is never decoded. What actually goes wrong on these cavities is far more ordinary than the message suggests: the three door interlocks in series, which are wear parts and stop the machine dead when one of them disagrees.
Where this appears, and which table it belongs to
On the appliance's own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all.
Which machines this one applies to
OM8334S, OT8687S, OP8664A, OCM8456S. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 8 of the appliance types this site publishes — cooktop, dishwasher, dryer, microwave, oven, range, refrigerator and washer — and publishes none at all for commercial line, freezer, microwave, oven, range, range hood and refrigerator. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door.
What to do about it
- Power off for a few minutes and restore, as the manual asks.
- Test the two halves separately — a cup of water for a minute tells you whether the microwave side works while convection does.
- If the door needs a push or feels loose, stop using it and say so when you call.
Where this goes next
The job this usually becomes is diagnostic visit, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 363-1406 and describe what the panel is doing before booking anything.
