What does error code mean e21

1. Remove any excess water before removing the base of the machine to release the pump.
2. Check and remove any blockages preventing the circulation pump from turning and Replace if any damage is found.

1. Pull the machine out from the wall.
2. Then take the panel out in the rear. Once the panel is off you will see the drain pump.
3. Disconnect the drain Tube between the Tub and the Pump.
4. Look inside the pipe you will find the Drain Filter.
5. Clean the filter out ( you will be surprised of "things" found in the filter) then put the machine back together
6. Try a full cycle.

I appreciate your inquiry, Bill Payer!

I understand that your Electrolux range is displaying error codes "E21" and "E39" and you are waiting for a part to become available to change. Based off the error codes "E21" stands for key sensor for cook place two which means a potential issue with the left board. "E39" stands for incorrect configuration. To configure your cooktop you would need to press and hold the "Warm" key, then press right front "Power" key until it beeps. Then press left front key and the configuration should start. If that does not help your situation I would suggest having a professional out for proper diagnosis. This will help to avoid any unnecessary part purchases. Best of luck! -Matt
