The error code E21 on a washing machine typically signifies a draining issue, indicating that the appliance is unable to effectively remove water from its drum. This problem is common across many washing machine brands, including Kenmore models.
Understanding the E21 Error
When your washing machine displays an E21 error, it means the machine is detecting that water is not draining as it should be. This can lead to various problems, such as a tub full of water at the end of a cycle, or the machine stopping mid-cycle.
Common Causes of E21 Draining Issues
The inability of a washing machine to drain water, resulting in an E21 error, can stem from several factors, with the most frequent culprit being an obstruction within the drainage system.
- Blocked Drain Pump Filter: This is a very common cause. The drain pump filter is designed to catch lint, small items (like coins, buttons, or socks), and debris before they reach and damage the pump. If this filter becomes clogged, it can significantly restrict or completely block the flow of water out of the machine, preventing the water from draining.
- Practical Insight: Over time, lint and small forgotten items in pockets accumulate, forming a barrier that prevents proper drainage.
- Kinked or Clogged Drain Hose: The hose that carries water from the washing machine to your standpipe or utility sink can become kinked, bent, or internally clogged with lint and detergent residue, impeding water flow.
- Malfunctioning Drain Pump: If the drain pump itself is faulty, damaged, or has a foreign object stuck in its impeller, it will be unable to pump water out, triggering the E21 error.
- Pressure Sensor Malfunction: The pressure sensor monitors the water level in the tub. If it's faulty, it might incorrectly detect that there's still water in the tub, preventing the drain cycle from completing or even starting correctly.
What Happens When E21 Occurs?
When the E21 error appears, your washing machine will often:
- Stop its current cycle.
- Leave water standing in the drum.
- Refuse to start a new cycle until the draining issue is resolved.
Troubleshooting Steps for E21
To address an E21 error, it's often advisable to check the most common causes first:
| Component to Check | Description | Action |
|---|---|---|
| Drain Pump Filter | Located typically at the bottom front of the machine, behind a small access panel or kick plate. | Unplug the machine, drain residual water (if possible), then carefully unscrew and clean the filter of any debris. |
| Drain Hose | The corrugated hose extending from the back of the washer. | Check for kinks or bends. Disconnect it and check for blockages. |
| Household Drain/Standpipe | The drain where the washer's hose empties. | Ensure it's not clogged. |
Always unplug your washing machine before performing any inspection or maintenance to ensure safety.
By addressing these potential issues, you can often resolve the E21 error and restore your washing machine's draining functionality.
