What the washer is detecting
The control checks the frequency of the incoming power. An unexpected frequency usually points at the power source, such as a generator or inverter, or at the control's sensing circuit.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Possible Running the washer from a generator, inverter or other non-utility power source with an unstable frequency.
- Possible A main control fault in its line-sensing circuit.
Safe checks you can make
- If the washer is on a generator, inverter or backup system, try it again on normal utility power.
- Unplug the washer (or switch off its breaker) for one minute, then restore power and start a new cycle to see whether the code comes back.
This stage requires professional testing. Full diagnosis involves hazards such as live line voltage, gas, a sealed refrigerant system or microwave high voltage. Do not attempt it yourself.
What a technician checks
- Checks the supply and the control's line sensing; supply testing requires professional testing because line voltage is present.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Washer main control board replacement | $300–$720 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. Do not keep running the washer on the source that caused the code. If it appears on normal utility power, have it diagnosed.

Repair or replace?
A fault code alone rarely justifies replacing a washer. Most F1E7 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 10–13-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
