Speed Queen Washer Er OF — What It Means & How to Fix It
Er OF on a Speed Queen front-load washer means the drum has filled to the overflow level.
What this code means
According to the guide, this code indicates the washer has filled to the overflow level, and the machine will attempt to pump the water out if the door is closed and locked. The one owner check it gives is the foreign object trap in the pump, which may be clogged and stopping that water getting away.
Checked against Alliance Laundry Systems' user's guide for Speed Queen frontload washers with a digital display (Part No. 805004R3). Speed Queen top-loaders report faults differently, so use the guide for your own model.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Clogged pump trap preventing the washer from pumping out | Common | Yes — screwdriver, 20 min |
| Water inlet valve not shutting off | Occasional | No — technician job |
| Water level sensing fault | Occasional | No — technician job |
What you can try yourself
- Leave the door closed and locked so the washer can pump the water out.
- Once it has emptied, disconnect the power and clean the foreign object trap in the pump, behind the lower front access panel.
- Reconnect the power and run a short cycle while you watch the fill.
- If the code does not clear, unplug the machine and call for service.
Seeing the symptom rather than the code? Washer not filling: checks that apply across brands.
When to call a technician
- Water keeps entering the drum with the washer switched off — turn the faucets off.
- Er OF returns on the next cycle with a clean trap.
- Water is leaking from the door or the base.
Typical professional repair cost: Free if the trap was the problem. An inlet valve or level-sensor repair is typically $150–$300 through a servicer.
Frequently asked questions
Is Er OF dangerous?
It means there is too much water in the drum. The washer tries to pump it out by itself; if water continues to come in, shut the faucets off and call for service.
Why should I keep the door closed during Er OF?
The guide says the machine attempts to pump the water out only if the door is closed and locked.
