Search for an Asko laundry fault code and you will find several lists that contradict each other. The reason is not that one of them is lying; it is that Asko changed how its machines report faults more than once, and lists that mix the generations produce nonsense. Here is what each generation actually does.
1. The Knob That Stops at a Letter
The earliest Asko washers sold in the United States, the W600 and W620 families, had no display and no codes. When something went wrong the program knob stopped at a marked position, and Asko documented exactly two of them. Position C, in the manual's own words, indicates a problem that can probably be taken care of without calling a service technician; it covers a thermistor fault, a heating element fault, a programmer fault, a water inlet fault and a draining fault. Position S usually indicates a mechanical problem and a service call will be required; the service manual lists a motor fault, a level sensor fault or a program fault. That is the entire diagnostic vocabulary of the machine, and it is more useful than it sounds, because it sorts the problem into owner-fixable or not before anyone opens anything.
2. Plain-Language Messages
The W640 and W660 generation, along with the WMC and WM70 platforms and the later condenser dryers, replaced the knob with a display that writes the fault out in words. There are no numbers to look up. Documented washer messages include Foaming, Overflow, Pressure sensor fault, Temperature stop, Thermistor fault, Wash motor fault, Water inlet fault, Water outlet fault, Draining fault, Door lock and Unbalance. Dryers of the same era show Over flow, Max Program Time, Thermistor fault, Clean condenser, Clean Lint Filter and Sensor fault. The service manuals give a reset: switch the machine off at the main power switch after carrying out the corrective action. On the WM70 the documented reset is pressing the door opening button at the same time as the main power switch.
3. The W6000 Numeric Codes
The W6000 generation, including the US W-series machines, introduced numbers, and there are only three of them that Asko itself publishes: F10 Overfilling, F11 Drainage error, and F12 Water inlet fault. Each comes with an owner procedure. Asko's clearing instruction for this generation is simple: after taking measures, turn the machine off and then back on to exit the message.
This is the point where the web goes wrong. Several parts retailers publish full F1 to F9 tables for Asko washing machines, and three of those lists disagree with each other completely on what each number means. No Asko manual assigns single-digit F-codes to a washing machine at all. If you have an Asko washer showing a single-digit F-code, do not trust a table you found; note what the machine was doing and have it read properly.
4. The Logic Generation: Error X Plus INFO
Current and recent Asko laundry, the Logic, Pro Home, Craft and Elements machines, display Error followed by a number, and Asko's manual wording is that in case of a failure while a program is in progress, the relevant Error X is indicated on the display unit. Holding the INFO button shows the description in words, and Exit returns to the main menu. Sub-codes use a decimal point, which is why you will see E7.1 and E13.1 and E13.2. Washers run from E0 up to E37, with the higher numbers belonging to machines fitted with the automatic dosing system; dryers use a much shorter E0 to E9 table with no E5.
Alongside the numbered errors sit plain-text alerts that use the same display, including UNBALANCE, UNABLE TO LOCK DOOR and STERIL TUB ALERT, the last of which is a prompt to run the drum cleaning program rather than a fault.
Why This Matters Before You Call
Report what the machine shows, character for character, and say which generation it is by giving the model number. A number without its generation is ambiguous, and a description from the INFO button is worth more than either. Bring both to an Asko dryer repair or washer booking and the diagnosis starts from evidence rather than from a list that may not apply to your machine at all.
