Speed Queen Washer Er, SH Error Code: What It Means & What to Check
Q: My Speed Queen washer is showing Er, SH. What does it mean, and what should I check?
A: On many Speed Queen washers, Er, SH means a shorted thermistor sensor error. In plain English: the washer’s control is seeing an abnormal signal from the water temperature sensor (often described as a “short circuit”). When the washer can’t trust the temperature reading, it may stop to protect the machine and prevent unsafe or incorrect temperature behavior.
This is typically a repair-related issue (sensor, wiring, or control), but you can do a few safe checks at home before calling our friendly technicians in yellow.
What you might notice
- The washer stops and displays Er, SH
- Warm/hot settings don’t behave normally
- Error appears early in the cycle or soon after filling
- Cycle may pause, then shut down with the code
- In some cases, the washer may refuse to start a cycle
Safety first
- Don’t attempt electrical testing or internal disassembly.
- Unplug the washer before checking anything behind it.
- If you notice a burning smell, visible damage, or repeated breaker/GFCI trips, stop using the washer and schedule service.
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) Confirm water supply basics (rule out confusing symptoms)
- Make sure both HOT and COLD wall valves are fully open.
- Check that inlet hoses are not kinked or pinched behind the washer.
- Try a brief fill on Cold, then on Hot to confirm both sides flow normally.
Why this matters: Er, SH is about the temperature sensor signal, but supply problems can sometimes create misleading temperature behavior. Ruling out simple fill issues helps.
3) Avoid specialty high-temp cycles until it’s fixed
- If the washer allows it, test with a small load on a standard cycle and choose Cold.
- If Er, SH returns immediately even on cold, that points strongly to a sensor/wiring/control issue that needs service.
4) Consider recent changes
- If the washer was recently moved, installed, or the area got wet (leak/overflow), mention that. Moisture and stressed harnesses can contribute to sensor-circuit problems.
- If the error started right after a storm/power event, mention that too—electronics sometimes fail after surges.
5) Document the pattern
- Does it happen immediately at start, or after filling?
- Does it only happen on certain cycles/temps?
- Any other codes with it?
Common causes (and likely parts)
- Thermistor (water temperature sensor) reading shorted/failed
- Wiring harness/connector shorted, pinched, or corroded in the sensor circuit
- Moisture intrusion at a connector causing an abnormal reading
- Control board reading the sensor incorrectly (less common)
When to call Beacon
If Er, SH returns after a reset—especially if it comes back on a simple cold test—call our friendly technicians in yellow. We can verify the thermistor reading, inspect the sensor wiring/connector for damage or corrosion, and restore normal temperature control so your washer runs safely and reliably.

Frequently Asked Questions
What’s the difference between Er, OP and Er, SH?
Both relate to the thermistor (temperature sensor). Er, OP usually means the sensor circuit looks “open” (no signal). Er, SH usually means the circuit looks “shorted” (abnormal low resistance/invalid reading).
Can I keep using the washer with Er, SH?
We don’t recommend it. If the washer can’t trust the temperature reading, it may stop mid-cycle and could manage water temperature incorrectly. It’s best to schedule service.
Will unplugging the washer fix Er, SH permanently?
A reset can clear a temporary glitch, but if the sensor or wiring is shorted, the code will return until the underlying issue is repaired.
Could moisture or a leak cause this?
It can. Moisture at a connector can create abnormal readings. If the error started after a leak or overflow, mention that when you call.
Does Er, SH mean the washer is overheating?
Not necessarily. It means the temperature sensor signal is not valid. Overheating/max-temp errors are different codes.
What should I tell Beacon when I call?
Tell us the code (Er, SH), whether it appears immediately or after filling, if it happens on every cycle, and whether the washer was recently moved or had any water leaks nearby. That helps our friendly technicians in yellow diagnose faster.
