Understanding the E21 Code

• During a wash cycle, the washer fills with water to the appropriate level for cleaning clothes.
• Before the spin cycle starts, the washer needs to drain out most of this water.
• The E21 code signifies that the washer is taking longer than expected (usually exceeding 8 minutes) to drain the water.

Causes of E21 Error

• Clogged Drain Hose or Filter: Lint, debris, or soap scum can accumulate in the drain hose or filter, hindering proper water flow and slowing down drainage.
• Blocked Drain Pipe: The drainpipe where your washer hose connects could also be clogged with debris or buildup, preventing water from flowing out efficiently.
• Faulty Drain Pump: In some cases, the drain pump itself might be malfunctioning and unable to pump out the water effectively, leading to slow drainage.
• Kinked Drain Hose: If the drain hose is kinked or bent, it can restrict water flow and hinder proper drainage.
• Improper Drain Hose Height: The drain hose outlet might be positioned too low or too high, affecting water flow due to siphoning or gravity issues.

Troubleshooting Steps for E21 Error

1. Clean the Drain Hose and Filter: Locate the drain hose filter, typically behind a small access panel at the bottom front of the washer. Clean any trapped debris and flush the hose with clean water.
2. Clear the Drain Pipe: If you suspect a clog in the drainpipe, disconnect the drain hose from the washer and clear any blockage you find in the pipe itself. You can use a plumber's snake or a wet/dry vacuum for this purpose.
3. Straighten the Drain Hose: Ensure the drain hose isn't kinked or bent in any way.
4. Check Drain Hose Height: Refer to your user manual for the recommended placement and height for the drain hose outlet. The hose should ideally be positioned at least 27½ inches (700 mm) from the floor to prevent siphoning.
5. Reset the Washer: Consult your user manual for specific instructions on resetting your GE washer model. A simple reset can sometimes clear temporary glitches.

If the E21 Code Persists after these steps

• Consult your user manual: The manual might have additional troubleshooting tips specific to your washer model.
• Contact a qualified appliance repair technician: They can diagnose the problem more precisely based on your washer model and error code. This might involve testing the drain pump, checking for wiring issues, or addressing other potential causes of slow drainage.

Additional Tips to Prevent E21 Error

• Avoid overloading the washer: Putting too many clothes in the washer can put extra strain on the draining system and contribute to clogs.
• Use the correct amount of detergent: Excessive suds can also interfere with proper drainage.
• Clean the drain hose and filter regularly: Regular cleaning helps prevent clogs and maintain efficient drainage.

By following these tips and troubleshooting steps, you should be able to identify and address the cause of the E21 error code on your GE washer and ensure a proper draining process before the spin cycle. If the error persists, consulting a qualified appliance repair technician is recommended for a more precise diagnosis and repair.
