What E2 Means
WHICH MACHINES THIS APPLIES TO: the current Asko professional dryer platform - the TD75.C17 series, which covers the TD75.C17X, the TDC177XV, the TDC177 series and the TDC1773VP.S. Unlike the older commercial dryers, these machines report numbered E-codes, and the manual states the mechanism plainly: in the event of a failure while a program is in progress the relevant error is shown on the display, and pressing and holding the INFO button displays the error description. That INFO gesture is the most useful thing to know about this platform, because it turns a bare number into a sentence without any code list at all.
WHAT THIS PLATFORM IS NOT: the TDC33 and TDC44 commercial dryers do not use E-codes. They print plain-worded messages, and those are separate entries here. Do not read a meaning from one platform onto the other.
THE GAPS IN THE SEQUENCE ARE REAL: the failure table on this platform runs E0, E1, E2, E6, E7, E8, E9, E10 and E11. There is no E3, E4 or E5 in it. Nothing should be invented to fill those spaces.
WHAT E2 MEANS: the failure display table gives the description "Communication error", with the action to call the service center.
WHAT IS COMMUNICATING WITH WHAT: these dryers have more than one electronic board. The panel you press is not the board that runs the machine, and the two exchange information continuously. E2 says that exchange is not working. Asko does not publish which link has failed, and no link is named here that the manufacturer has not named.
WHY IT CAN LOOK LIKE SEVERAL DIFFERENT PROBLEMS AT ONCE: when boards lose contact, what you see depends on which end is still alive. The display may go blank, freeze, show the code and nothing else, or the buttons may simply do nothing. None of that tells you anything about the drum, the heating or the air path, which is worth saying because a dead-looking panel in a busy room usually gets reported as a dead machine.
A NEIGHBOURING CODE ON THE SAME PLATFORM: E11 is a motor communication error and E10 is another communication error again. They are separate entries because Asko separates them, and which number you have narrows the search considerably.
CLASSIFICATION: problem. No owner check is published.
Common Causes of E2
- Harness or connector between the boards damaged or disturbed
- One of the boards failed
- Supply disturbance or a power cut the boards did not recover from
- Moisture or lint on a connector
- Vibration over long service loosening a connection
🔧 One Safe Check You Can Try
A complete power-down is the one thing worth doing and it is worth doing properly: switch the dryer off at its breaker or wall isolator, leave it a full minute so every board loses power rather than resting in standby, then restore it and start a cycle. If the code returns, take the machine out of service with a notice on it and report it. Note what is worth knowing first: whether the panel responds at all, whether the drum turned before it stopped, whether the machine had recently been moved, whether the room had a power cut or work done on the supply, and whether other machines in the room showed anything at the same time. A whole run of machines reporting oddly on the same morning usually means the supply rather than the machines. Do not take the control panel or the rear panel off to look at connectors - the boards and their harness are at mains voltage whenever the machine is fed, and on a heat-pump machine the sealed refrigerant circuit is behind the same panels.
⚠ Why You Shouldn't Go Further Than That
- Asko publishes no owner check for this code on this platform - the action column says to call the service center.
- The control boards and their wiring carry mains voltage whenever the machine is fed, and on a heat-pump machine the sealed refrigerant circuit sits behind the same panels.
- A professional dryer is normally hard-wired and may be ducted and standing in a run of machines, so isolating it means the breaker or wall isolator rather than a plug, and reaching the back of it means moving a machine.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
