What Erdn means on a Speed Queen washer

The Erdn error code on a Speed Queen washer indicates a drain count error. This fault is triggered when the control board detects that the machine has attempted to drain an excessive number of times within a cycle, or that the drain sequence has not completed within the expected parameters. The control monitors drain events throughout the wash cycle, and when that count exceeds the programmed threshold, the error is logged and the cycle is interrupted.

The drain system on a Speed Queen washer involves several components working together: the drain pump, the lid switch or door latch assembly, water level pressure switch, and the main control board. If the pump is running but water is not evacuating at the correct rate, the controller may repeatedly attempt drain sequences, eventually triggering the Erdn fault. A clogged pump filter, blocked drain hose, or a failing pump motor are the most frequent hardware causes.

Because the fault behavior can vary depending on the specific model, the root cause may differ between top-load and front-load configurations. On some models, a faulty water level pressure switch can falsely indicate standing water, causing the board to initiate repeated drain attempts even when the tub is empty. On others, a slow or intermittent drain pump may complete partial drains but fail to satisfy the control board's completion criteria, accumulating drain count errors until the fault code is set.

Common causes of Erdn

  1. 01

    Clogged drain pump filter or pump inlet

    Wiring / connection

    Lint, coins, or small garments can block the pump filter or inlet, restricting water flow and causing repeated failed drain attempts. Check and clean the pump filter if your model provides access to one.

  2. 02

    Kinked or blocked drain hose

    Wiring / connection

    A drain hose that is kinked, pinched, or inserted too far into the standpipe can restrict or completely prevent water from exiting. Inspect the full length of the drain hose and verify it is properly routed.

  3. 03

    Faulty or worn drain pump

    Part replacement

    A drain pump with a failing motor or worn impeller may run but move water too slowly to satisfy the control board, triggering repeated drain cycles and eventually the Erdn fault. Listen for unusual humming or grinding from the pump during the drain phase.

  4. 04

    Defective water level pressure switch

    Part replacement

    If the pressure switch is faulty or its sensing hose is clogged or disconnected, it may incorrectly signal that water is still present in the tub after draining, causing the control to initiate additional drain attempts. Inspect the pressure switch hose for blockages or cracks.

  5. 05

    Control board fault

    Part replacement

    In less common cases, the main control board itself may be misreading drain cycle data or incorrectly incrementing the drain count due to an internal fault. This is typically considered only after all other components have been tested and confirmed functional.

Frequently asked questions about Erdn

What does Erdn mean on a Speed Queen washer?
Erdn stands for drain count error on a Speed Queen washer. It means the control board detected that the machine performed too many drain attempts during a cycle without successfully completing the drain sequence. The fault is typically caused by a blockage in the drain system, a failing pump, or a faulty water level pressure switch. The washer will interrupt its cycle when this code appears.
Can I fix the Erdn error on my Speed Queen washer myself?
Some causes of the Erdn error are DIY-friendly. Checking and clearing a clogged pump filter, straightening a kinked drain hose, and confirming the standpipe height is within the correct range can all be done without special tools. If the pump or pressure switch needs replacement, a technician with appliance repair experience may be needed, particularly on models where internal access requires disassembly.
Is it safe to use my Speed Queen washer when the Erdn code is showing?
You should not continue running the washer while the Erdn code is active. If the machine cannot drain properly, water may remain in the tub, and forcing additional cycles could stress the pump motor or cause water to overflow. Resolve the underlying drain issue before resuming normal use.
Will resetting my Speed Queen washer clear the Erdn error?
A reset may temporarily clear the Erdn code, but if the underlying cause is not addressed, the error will return during the next cycle. To reset, unplug the washer for one to two minutes and then restore power. If the code reappears, focus on diagnosing the drain pump, filter, hose, and pressure switch before running another cycle.
How much does it cost to repair a Speed Queen washer with an Erdn error?
Repair costs depend on the root cause. Clearing a clogged filter or repositioning a drain hose costs nothing beyond your time. A replacement drain pump typically runs in the range of $40 to $120 for the part, with labor adding $80 to $200 if a technician is needed. A new water level pressure switch is generally less expensive, often in the $15 to $50 range for the part alone.
