What the Er 01 error code actually means

Your Electrolux dishwasher has detected water collecting underneath the tub, which means there is a leak somewhere inside the machine. The dishwasher has stopped running to protect your home from water damage. You should turn off the dishwasher and contact Electrolux support before using it again.

Questions people ask about Er 01

What does Er 01 mean on a Electrolux dishwasher?
Er 01 means the dishwasher's leak detector has sensed water accumulating in the base pan beneath the tub. The unit shuts down automatically to prevent further water damage. This code indicates a real water leak in most cases and should be diagnosed before the dishwasher is used again. Electrolux recommends calling their Customer Care Center at 1-877-435-3287 for assistance.
Is it safe to keep using my dishwasher when it shows Er 01?
No, you should not continue running the dishwasher when Er 01 is displayed. Water in the base pan can cause electrical shorts, accelerate corrosion of internal components, and damage your flooring or cabinetry. Power off the unit and avoid use until the leak source has been identified and repaired.
How much does it cost to repair an Er 01 error on an Electrolux dishwasher?
Repair costs vary depending on the cause of the leak. Simple fixes like a door gasket replacement may cost in the range of $75 to $150 including parts and labor. More involved repairs such as a pump seal or inlet valve replacement can range from $150 to $350 or more depending on parts and local labor rates. Contacting Electrolux at 1-877-435-3287 can help clarify whether the repair is covered under any warranty.
Can I fix an Er 01 error myself, or do I need a technician?
Some simple causes like excess detergent foaming can be resolved without a technician, but most causes of Er 01 involve internal components that require removing access panels and working near electrical and water connections. Because the code involves an active water intrusion, Electrolux directs customers to contact their support line at 1-877-435-3287 rather than attempting self-repair. A trained technician can safely identify the leak source and replace the appropriate component.
Will resetting the dishwasher clear the Er 01 error code?
A power reset may temporarily clear the error display, but it will not resolve the underlying leak. If water remains in the base pan or the leak source has not been fixed, the detector will activate again as soon as the dishwasher runs. The error will continue to return until the cause of the water intrusion is properly repaired.
