What error code 20 means on a GE GFW front-load washer

This is a leak protection code. Codes and wording can vary by model, so check your owner's manual for your model number.
How to fix GE GFW front-load washer error code 20 (safe owner checks)
- Write down the code and model number. Note exactly what the display shows (20) and copy the full model number from the rating label, so you can confirm this chart applies to your GFW front-load washer and order the right parts.
- Reconnect the air hose. Reconnect the air hose if it’s loose.
- Check the power supply. Check to see if the tub fills with water when the power cord is unplugged.
- Do a power reset. Unplug the appliance or switch off its breaker for one minute, then restore power and try again. If the code clears and stays away, it may have been a one-off fault.
- Test and decide. Run a short cycle or restart and watch the display. If 20 comes back after these checks, stop using the washer for this function and call a technician, because the remaining causes need meters or part replacement.
The first and last steps (and the power reset) are general owner checks added by ErrorCodePro; the rest follow the GE GFW front-load washer error-code chart published by Sears PartsDirect, rewritten for safe owner use.

When to call a technician
- Unplug the washer, and then check the air hose between the bottom of the tub and the connection on the electronic control board.
