Electrolux Washer Error Code E37

E37 means the washer is not detecting any pressure difference in its water level sensing system. The fault is caused either by a blocked airtrap that cannot transmit air pressure changes, or by a pressure sensor circuit whose input voltage is stuck at 0V or 5V rather than varying normally. Both conditions prevent the machine from accurately determining how much water is in the drum, so the washer stops operation and displays the code.

It is not recommended to continue running the washer while E37 is active. Without accurate water level sensing, the machine cannot properly control the amount of water entering the drum, which could lead to overfilling or incorrect cycle operation. Stop use until the fault is diagnosed and resolved.

A power reset may temporarily clear the code, but it will return if the underlying cause has not been corrected. If the airtrap is blocked or the sensor circuit has failed, the fault condition still exists after a reset and the washer will display E37 again once it attempts to sense water level. Always address the root cause rather than relying on resets.

In many cases, yes. The most common cause is a clogged airtrap or connecting hose, and cleaning these parts is a straightforward task that requires no special tools. Locate the airtrap near the bottom of the drum housing, disconnect the hose, and clear any debris or detergent buildup from both the chamber and the hose. If the code returns after cleaning, further diagnosis of the wiring and electronic components may require a technician.

Repair costs vary depending on the cause. If the airtrap just needs cleaning, there may be no parts cost at all, only your time or a basic service call fee. Replacing the airtrap assembly is generally an affordable parts cost, typically in the range of $10 to $40. If the control board needs replacement, parts and labor combined can range from $150 to $400 or more depending on your model and region.
