Speed Queen Washer Error Code oF
Overflow condition
Common Causes
- 1Water inlet valve stuck open
- 2Pressure switch failure
- 3Control board relay stuck
Step-by-Step Troubleshooting
- 1
Shut off both water supply valves immediately to stop further filling
- 2
Watch whether water keeps entering with the supply off — continued flow means a drain-line siphon, not a valve fault
- 3
Check that the drain hose is not pushed too far down the standpipe, which siphons water back into the tub
- 4
Inspect the pressure-switch hose on the tub for splits or trapped water that blocks an accurate level reading
Pro Diagnostic Tip
Turn off water supply immediately. If water continues entering with supply off, the inlet valve is not the problem — suspect a siphon from drain connection.
You Might Also Notice
- •Water rises above the door glass or the top of the tub
- •Machine keeps filling and will not begin washing
