ASKO Washer Error Code E1

E1 on an Asko washer signals a water level detection error. The control board is either not receiving confirmation that the water level has reached or fallen below the required reset point, or it is detecting an overflow condition during line test mode. The fault originates in the water level sensing system, which includes a pressure sensor and a connected pressure hose. The machine may keep the water supply motor running as part of its response to this fault.

It is not recommended to continue running the washer while E1 is active. Because the fault involves water level detection, the machine may overfill or behave unpredictably with the water supply motor staying energized longer than intended. Running the machine in this state increases the risk of water damage. The issue should be diagnosed and resolved before resuming normal use.

A reset may temporarily clear the E1 code and allow the washer to attempt another cycle, but if the underlying cause such as a defective pressure hose or faulty water level sensor is still present, the error will return. Resetting without diagnosing the root cause is not a lasting solution. The pressure hose and water level sensor should be inspected before relying on a reset to restore normal operation.

Some causes of E1 are accessible to a knowledgeable DIYer. Inspecting the pressure hose for kinks, cracks, or disconnected ends and checking that water supply valves are fully open are reasonable first steps. Cleaning a blocked pressure hose requires no special tools. However, testing and replacing the water level sensor involves electrical diagnosis and component replacement that may be better suited to a qualified technician.

Repair costs depend on what component is at fault. If only the pressure hose needs cleaning or reseating, the cost may be minimal. Replacing the pressure hose typically falls in the range of $20 to $60 for parts. A water level sensor replacement can range from $40 to $120 for the part alone, with labor costs adding $80 to $200 depending on your location and the service provider.
