Ariston Refrigerator Error Code Et

Ice maker tray horizontal position incorrect

Ariston codesAriston refrigerator codes

Ice maker tray horizontal position incorrect - occurs when level sensor signals an error (no pulses detected for a certain period of time).

First step from the service manual

Water supply mode no longer valid (tray horizontal position); error terminates when sensor normal status is restored.

What Et means on a Ariston refrigerator

The Et error code on an Ariston refrigerator indicates that the ice maker tray is not in the correct horizontal position. The control system monitors the tray's orientation through a level sensor that generates pulses to confirm proper positioning. When the system fails to detect any pulses from this sensor over a defined time period, it interprets this as a positional fault and triggers the Et code. The ice maker enters a halted state, and the water supply mode is suspended because dispensing water into an improperly positioned tray would cause spills, incomplete ice formation, or mechanical damage to the assembly.

The level sensor is central to the ice maker's operating cycle. During normal operation, the sensor continuously signals the control board with pulse feedback confirming that the tray is level and ready to receive water or initiate an ejection cycle. A break in this pulse signal, whether caused by a failed sensor, a wiring fault, or a physically misaligned or stuck tray mechanism, triggers the error condition. The error will clear automatically once the sensor returns to a normal signaling state, meaning no manual reset is required if the underlying issue resolves itself.

Diagnosing Et starts with inspecting the ice maker tray physically to confirm it is not jammed, obstructed, or mechanically stuck in an off-level position. If the tray appears normal but the error persists, the level sensor and its associated wiring harness should be checked for continuity and secure connections. Ice buildup around the tray mechanism is a frequent contributor, as it can physically prevent the tray from returning to its horizontal home position after an ejection cycle.

Common causes of Et

  1. 01

    Ice or frost buildup jamming the tray

    Wiring / connection

    Excess ice accumulation around the tray mechanism can physically block it from returning to the level home position after an ejection cycle. Inspect the ice maker compartment for frost or ice bridges holding the tray at an angle.

  2. 02

    Tray mechanically stuck or obstructed

    Wiring / connection

    A foreign object, a cracked tray, or a worn drive component can prevent the tray from rotating or settling into its correct horizontal position. Manually cycling the tray while the ice maker is off can reveal binding or resistance in the mechanism.

  3. 03

    Failed or disconnected level sensor

    Part replacement

    The level sensor responsible for generating position pulses may have failed electrically or become disconnected from its wiring harness. If the tray appears correctly positioned but the error persists, inspect the sensor and its connector for damage or looseness.

  4. 04

    Wiring harness fault between sensor and control board

    Wiring / connection

    A damaged, pinched, or corroded wire in the harness connecting the level sensor to the main control board will interrupt pulse transmission even if the sensor itself is functioning. Check the harness routing for any signs of wear or corrosion at the connector pins.

  5. 05

    Defective ice maker control module

    Part replacement

    If the sensor, wiring, and tray mechanism all check out correctly, the ice maker control module itself may be failing to read or process the sensor signal. This is the least common cause and typically requires replacing the ice maker assembly or the module.

Frequently asked questions about Et

What does Et mean on a Ariston refrigerator?
The Et code means the ice maker tray is not in the correct horizontal position according to the level sensor. The sensor works by sending pulses to the control board to confirm proper tray alignment, and when those pulses stop being detected for a set period, the Et error is triggered. The ice maker's water supply mode is suspended until the sensor returns to a normal signaling state. The error will clear on its own once the tray position and sensor operation are restored.
Can I fix the Et error myself without calling a technician?
In many cases, yes. Start by checking for ice or frost buildup around the ice maker tray, as this is a common cause that can be resolved by defrosting the compartment manually. If the tray appears physically jammed, carefully clear any obstruction and confirm the tray can move freely. If the error continues after the tray is visibly level and unobstructed, the sensor or wiring may need professional inspection.
Will resetting the refrigerator clear the Et error code?
A power reset alone will typically not permanently clear the Et error if the underlying cause is still present. The code is designed to clear automatically once the level sensor returns to normal operation and begins producing pulses again. Resetting the unit may temporarily clear the display, but the error will return if the tray position or sensor issue has not been resolved.
Is the Et error a safety concern, and can I still use the refrigerator?
The Et error affects only the ice maker function and does not impact the refrigerator's cooling or food preservation capabilities. Your refrigerator will continue to cool normally while this error is active. It is safe to continue using the unit for food storage, but ice production will be halted until the fault is corrected.
How much does it cost to repair the Et error on an Ariston refrigerator?
Repair costs vary depending on the root cause. If the issue is simply ice buildup or a physical obstruction, there may be no parts cost involved. Replacing a faulty level sensor or wiring harness typically runs in the range of $50 to $150 for parts and labor. If the ice maker module or assembly requires replacement, costs can range from $100 to $300 or more depending on parts availability and local labor rates.
