Speed Queen Washer Error Code OF, St

OF, St means the washtub has filled with water up to the overflow level, triggering a protective stop in the wash cycle. The machine detects this condition through its water level sensing system and halts operation to prevent flooding. Pressing the Start/Pause button within five minutes will initiate a spin to pump out the excess water. If that window is missed, the code escalates to Er, OF and the machine must be unplugged for 15 seconds to reset.

Unplugging the machine for 15 seconds is required only if the error escalates to Er, OF, which happens when Start/Pause is not pressed within five minutes of OF, St appearing. Simply clearing the code will not fix the underlying cause of the overfill, so the error is likely to return if the faulty component is not repaired or replaced.

Repair costs depend on which component has failed. A replacement water inlet valve typically runs in the range of $25 to $75 for the part, while a water level pressure switch generally costs between $15 and $50. If professional labor is involved, total repair costs including diagnosis and parts can range from $100 to $250 or more depending on your location and the specific component requiring replacement.

Start by pressing the Start/Pause button to trigger a spin and drain the excess water. Once the tub is clear, inspect the water inlet valve for signs of failure, check the pressure switch hose for kinks or blockages, and test the water level pressure switch. If the inlet valve is not closing fully, replacing it is typically the most direct fix for a recurring overfill condition.

You should not run a new wash cycle until the cause of the overfill has been identified and corrected. An overfill condition can result in water spilling onto the floor, which creates a slip hazard and potential water damage to flooring and nearby structures. The machine's built-in recovery step, pressing Start/Pause to spin out the water, is safe to use, but continuing to operate the washer without addressing the root cause is not recommended.
