Here's what you can do to troubleshoot the F02 error

1. Check the Drain Hose - Make sure the drain hose isn't kinked, clogged, or blocked by something. You can also ensure it's positioned correctly at the drainpipe.
2. Clean the Drain Filter - Most Kenmore washers have a drain filter, typically located at the bottom front panel behind a small access door. Consult your washer's manual for the exact location. Clean the filter of any debris or buildup that might be hindering water flow.
3. Inspect the Drain Pump - If cleaning the filter doesn't solve the issue, there might be a clog within the drain pump itself. You'll likely need to refer to your washer's manual for instructions on accessing and cleaning the drain pump. Be aware that this might involve some disassembly and may require caution.
