E21

Slow Drain or Drain Fault

Severity

High

When a GE Washing Machine shows E21 on its display, the internal diagnostic system has flagged a condition known as "Slow Drain or Drain Fault". Most repairs for this code are straightforward and can be completed at home.

Owner's Summary

Your GE washer detected a drain problem. The filter at the bottom front of the machine collects lint, coins and small items over time — cleaning it is free and fixes most E21 errors in under 15 minutes.

Symptoms

GE washer draining slowly or not draining, standing water in drum, E21 code

Common Causes

Clogged pump filter
Blocked or kinked drain hose
Faulty drain pump
Excessive suds from wrong detergent

How to Fix

1 Clean the pump filter and remove all debris
2 Inspect and straighten drain hose
3 Use only HE detergent in the correct amount
4 Replace drain pump if filter is clear and hose is unobstructed

Tools You'll Need

Pliers Soft Brush Towels / Bucket Flashlight

Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.

Technical Explanation

The GE control board monitors the pressure transducer signal during the drain cycle. E21 is triggered when the drum water level does not fall below the low-level threshold within the maximum allowable drain time, indicating restricted or failed drainage.

Is It Safe to Keep Using?

Fix same day to prevent mold and mildew in the drum.

Technician's Pro Tip

GE washers that share a drain standpipe with a nearby sink can develop siphoning issues — water that drains out gets pulled back in by negative pressure. Install a proper standpipe with an air gap if you suspect this is contributing to drain errors.
