What T6 Means
WHICH MACHINES THIS APPLIES TO: this code belongs to the Asko wine climate cabinet WCN311942G and it comes from that cabinet's own instruction book. The WCN311942G is a three-zone cabinet with a touch display, and the code alphabet it uses - E, F, H, P, T and U letters sorted by the part that reported the problem - belongs to this cabinet and to nothing else in the Asko range. That matters more here than almost anywhere else on this site: the same short strings appear on Asko washers, dryers and drying cabinets with entirely different meanings, so a wine-cabinet F2 has nothing whatever to do with a washer F2 or a drying-cabinet F2.
HOW THE CABINET TELLS YOU: the code arrives as a pop-up notification on the touch display. It stays on the screen until it is dismissed with X or Confirm, and if the condition behind it has not been dealt with, the notification comes back three hours later. That timer catches people out. The message goes away when it is tapped, the cabinet seems fine all evening, and the same code is on the screen again in the morning. Nothing has gone wrong twice - the cabinet has simply looked again.
WHAT T6 MEANS: the part table in the instruction book reads "Temperature sensor error for zone B evaporator." It is the zone B counterpart of T3 - the sensor that reads the cold surface doing the cooling in that zone, rather than the air the bottles are in.
WHY THE NUMBER JUMPS FROM T4 TO T6: because Asko's printed list has no T5 in it. The same is true of T7. Those gaps are real, they were checked twice against the page they come from, and they are not there to be filled in. A code list that offers you a T5 or a T7 for this cabinet did not come from Asko's book.
WHAT THE SENSOR IS FOR: the coil temperature tells the control how the refrigeration side is behaving, which is a different question from how the wine is doing. The book does not say what this cabinet does with the reading or without it, so nothing is claimed here beyond the part and the zone.
WHAT MIGHT HAVE BROUGHT YOU HERE: frost or ice in zone B, that zone cooling unevenly, or a cabinet that runs and runs without getting the zone where it should be.
WHAT ASKO PUBLISHES BESIDE IT: the meaning only, with no action column and no described consequence.
Common Causes of T6
- Zone B evaporator sensor failed or out of range
- Wiring or connector to the sensor disturbed
- Sensor no longer in proper contact with the evaporator
- Ice build-up at the sensor position
- Power board not reading the sensor
🔧 One Safe Check You Can Try
Record what you can see and resist the temptation to intervene. Note every zone's setting and reading with the time, then look carefully into zone B for frost, ice or standing water, and photograph anything unusual before the cabinet cycles and hides it. Put an independent thermometer on a shelf in that zone, leave it several hours with the door closed, and compare it with the display. Keep the door shut otherwise, because every long opening puts more moisture into a cabinet that may already be struggling to manage it. Nothing should be scraped, chipped, warmed or levered: the evaporator is thin-walled, it is part of a sealed refrigerant circuit, and damaging it turns a sensor job into a replacement cabinet. If bottles in that zone are at the wrong temperature, move them to a zone that is holding and note when you did it. The sensor itself sits against the coil behind the interior surfaces, with live wiring in the same space, and it is not owner-accessible.
⚠ Why You Shouldn't Go Further Than That
- Asko prints the meaning of this code with no action beside it, so there is no manufacturer procedure for an owner to work through.
- The sensor is mounted against the sealed refrigerant circuit, which is thin-walled and must never be prised, scraped or heated.
- The sensor and its wiring sit inside the cabinet at mains voltage whenever it is connected to power.
