The Speed Queen washer error code E21 indicates a drain restriction, meaning the machine is having trouble pumping water out fast enough during the drain cycle. This is typically caused by a clogged drain pump filter, a kinked or blocked drain hose, or a failing drain pump. The good news is that most E21 errors can be resolved at home with basic tools and about 30 to 45 minutes of your time.

How to Fix Error Code E21

  1. Power Off and Unplug the Washer

    Always unplug the washer before opening any panels or accessing internal components. Failure to do so can result in serious electric shock or injury.
  2. Check and Clear the Drain Hose

    Be prepared for water to spill out when disconnecting the drain hose. Have towels and a bucket ready.
  3. Clean the Drain Pump Filter

    The water draining from the filter may be hot if the washer was running a hot cycle recently. Use caution to avoid burns.
  4. Inspect the Drain Hose at the Pump Connection

    If you need to tilt the washer, have a second person assist you to prevent injury or damage to the machine. Disconnect the power before tilting.
  5. Test the Drain Pump for Function

    Do not attempt to spin the impeller while the washer is plugged in. Sharp debris inside the pump can cause cuts — consider wearing protective gloves.
  6. Run a Test Cycle

  7. Check for Error Persistence and Reset the Washer

When to Call a Professional

You should call a qualified appliance technician if: the drain pump impeller is seized and you cannot free it manually; the pump motor has failed and needs to be replaced (confirmed by running correctly after all clogs are cleared but still draining slowly); the wiring harness connecting the pump to the control board shows signs of burning, corrosion, or damage; or the E21 error persists after completing all of the above steps and performing a control board reset. If your Speed Queen washer is still under its warranty — Speed Queen offers industry-leading 5-year warranties on many models — contact Speed Queen customer support or an authorized service provider before attempting any internal repairs, as unauthorized repairs may void the warranty.

Frequently Asked Questions

What does E21 mean on a Speed Queen washer?
Error code E21 on a Speed Queen washer means the machine has detected a drain restriction. The washer is not able to pump water out at the expected rate during the drain cycle. Common causes include a clogged drain pump filter, a kinked or blocked drain hose, or a failing drain pump.
Can I still use my Speed Queen washer after the E21 error?
It is not recommended to continue using the washer once the E21 error appears. Running cycles with a drain restriction can put extra strain on the pump motor, potentially causing it to overheat or fail completely. Address the error before running additional cycles to avoid more costly repairs.
How do I reset the E21 error code on my Speed Queen washer?
To reset the E21 error, first resolve the underlying drain restriction by cleaning the pump filter and clearing the drain hose. Then unplug the washer from the power outlet for at least 5 minutes. Plug it back in and run a rinse-and-spin cycle to confirm the error is cleared. Simply resetting without fixing the underlying issue will cause the code to return.
How often should I clean the drain pump filter on my Speed Queen washer?
Speed Queen recommends cleaning the drain pump filter every 1 to 3 months depending on how frequently you use the machine and what you wash. Households with pets, heavy workloads, or frequent washing of lint-producing items like towels and blankets should clean it monthly to prevent buildup and avoid errors like E21.
How much does it cost to replace a drain pump on a Speed Queen washer?
The cost to replace a drain pump on a Speed Queen washer typically ranges from $120 to $280 when done by a professional technician, including parts and labor. The drain pump part itself generally costs between $40 and $100 depending on the specific model. If your washer is under warranty, the repair may be covered at no cost to you.
