What E1 means
E1 on an ASKO Professional TDC1773VF.S or TDC1773VP.S dryer is read as a thermistor error, which means a temperature sensor problem. These TDC1773 models are sold in the US for multifamily and light commercial laundry rooms. The control watches drum and air temperature through thermistors, and E1 appears when a reading is missing or out of range. You may also see E1.1, E1.2 or E1.3, which narrow down which sensor circuit is involved.
Common causes of E1
- A thermistor with a reading out of range
- A loose or corroded sensor connector
- Damaged wiring between the sensor and the control
- The control board reading the sensor
1. Let the dryer cool completely, then clean the lint screen. 2. Check that the outside vent hood flaps open freely and the vent is not crushed behind the dryer. 3. Start one new cycle. 4. If E1, E1.1, E1.2 or E1.3 returns, stop using the dryer and note the exact code for us.
- Which of the sensor circuits E1.1, E1.2 or E1.3 is involved
- Whether the sensor, its wiring or the control reads wrong
- Whether a vent restriction is overheating the dryer and tripping the reading
Other Professional Laundry codes
Is E1 the same as E1.1 or E1.2?
They belong to the same thermistor group. The number after the dot tells us which sensor circuit is reporting a problem, so write down exactly what the display shows when you call.
Can a clogged vent cause E1?
A restricted vent can overheat a dryer, and heat can push a sensor reading out of range. We check the vent path along with the sensor, because fixing one without the other brings the code back.
