Speed Queen Washer Ed, 46 Error Code: What It Means & What to Check
Q: My Speed Queen washer is showing Ed, 46. What does it mean, and what should I check?
A: On many Speed Queen washers, Ed, 46 points to a heater control (HW on/off) failure. In plain English: the washer’s control tried to switch the water-heating circuit on or off, but the feedback it expected didn’t match what actually happened. That can be caused by a problem with the heater control circuit (relay/driver on the control), a heater component (on models that heat water internally), a temperature sensor reading that doesn’t make sense, or a wiring/connector issue.
Good to know: Not every Speed Queen washer heats water the same way. Some rely primarily on your home’s hot water supply, while others may have additional heating management. Either way, Ed, 46 usually means the washer is detecting an abnormal heater-control condition and stops to protect itself.
What you might notice
- The washer stops mid-cycle and displays Ed, 46
- The error appears more often on high-temperature or specialty cycles
- Water temperature seems “off” (not warming as expected, or unusual behavior around heating)
- Cycle may pause for a long time and then error out
Safety first
- Heater-related faults can involve electrical components. Avoid disassembly or electrical testing.
- If you notice a strong burning smell, unusual heat, or repeated tripping of a breaker/GFCI, stop using the washer and call for service.
- Unplug the washer before checking anything behind it.
Step-by-step quick checks (safe homeowner checks)
1) Power reset
- Press Power to stop the cycle.
- Unplug the washer for 2 minutes.
- Plug it back in and try a short test cycle.
2) Switch to a normal cycle (avoid high-temp options for the test)
- For troubleshooting, run a small load on a standard Normal cycle with Warm (or your typical setting).
- If Ed, 46 only happens on high-temperature/sanitize-style cycles, that’s an important clue for diagnosis.
3) Confirm your home hot water is stable (simple supply check)
- Run hot water at a nearby sink for a minute and confirm it gets hot and stays consistent.
- If the home’s hot water is lukewarm or fluctuating, temperature targets can be harder to meet and may trigger heater-related errors on some cycles.
4) Reduce competing hot water use
- Try running the washer when showers/dishwasher aren’t using hot water.
- Low or fluctuating hot water supply can contribute to temperature-related fault logic on some models.
5) Check basic airflow and environment
- In hot Florida laundry spaces, electronics can run warmer. Make sure the washer isn’t wedged tightly between cabinets/walls.
- Give it space to breathe and avoid back-to-back specialty cycles while troubleshooting.
6) If the code returns, stop repeated restarts and note the pattern
- Which cycle was running? Which temperature setting?
- Does it happen immediately, or after a long heat/wash period?
- Any unusual odors, noises, or pauses?
- This helps our friendly technicians in yellow pinpoint whether it’s sensing, control, or a heater-circuit issue.
Common causes (and likely parts)
- Heater control circuit issue (control board relay/driver not switching as expected)
- Temperature sensor/thermistor issue (reading incorrect or unstable)
- Heater component issue on models with internal water heating (heater/associated parts as applicable)
- Wiring or connector problem in the heater/sensor circuit (loose connection, damaged harness)
- Control board logic/communication issue (less common, but possible)
Note: The exact “likely part” depends on your washer’s model and whether the error appears only on certain cycles/temps.
When to call Beacon
If Ed, 46 returns after a reset and a normal test cycle—or it appears with any burning smell, unusual heat, or repeated stoppages—call our friendly technicians in yellow. Heater-control faults are typically not a DIY fix, and a proper diagnosis helps prevent repeat shutdowns or damage to the washer’s control system.

Frequently Asked Questions
Is Ed, 46 the same as Er, HT?
They’re related but not identical. Er, HT is commonly about not reaching a target temperature in time. Ed, 46 points more specifically to the washer detecting a problem switching the heater-control circuit on or off.
Can I finish the load if I restart the washer?
It’s best not to repeatedly restart. If the washer is detecting a heater-control fault, repeated attempts can lead to more stoppages. Try the reset and a normal-cycle test once; if it returns, schedule service.
Why does it happen more on sanitize or very hot cycles?
High-temperature cycles often use stricter temperature targets and tighter monitoring. If the washer sees abnormal heater control behavior during those cycles, it may trigger Ed, 46.
Could this be caused by my home’s hot water supply?
It can contribute to temperature-related behavior on some cycles. Unstable or insufficient hot water can complicate heating logic, but Ed, 46 typically points to an on/off control or feedback mismatch that may require service.
Does Ed, 46 always mean the control board is bad?
Not always. It can be the control, but it could also be a sensor reading issue, wiring/connector problem, or a heater-related component on models that heat water internally. Diagnosis is key.
What should I tell Beacon when I call?
Tell us the code (Ed, 46), the cycle and temperature selected, whether it happens only on high-temp cycles, and anything you noticed (long pauses, unusual heat, odors). That helps our friendly technicians in yellow arrive prepared.
