Fisher & Paykel ActiveSmart Ice & Water Code F31: Display Clock or Data Line Down

What F31 means

On Fisher & Paykel ActiveSmart Ice & Water refrigerators like the E522BRXU and E522BLXU, F31 means the display receives no signal on its clock or data line, caused by a shorted or broken wire. The ice and water panel may go blank or stop responding. There is no alarm or beeping, and cooling normally carries on. Dispenser buttons may not respond.

Common causes of F31

Clock or data wire broken in the display harness
Wire shorted against another conductor
Display module not communicating

✓ One safe check you can try

1. Unplug the unit for five minutes and restart it. 2. Wait a minute and check whether the panel lights up. 3. Try the water dispenser paddle to see if it still answers. 4. If F31 remains, call us instead of repeating restarts.

! Why to stop there

The wires cross a door hinge, so wear and pinching are common.
A short on the clock or data line can stop the whole panel.
We test the link wire by wire and put the price in writing first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F31F31 questions

What are the clock and data lines?

They are the two signal wires the display uses to talk with the control. If either is broken or shorted, the panel loses contact and shows F31.

Will I hear anything?

No. F31 has no alarm or beep. Only the panel behavior tells you something is wrong. They are the wires that carry the clock and data signals.

Can I keep using the refrigerator?

Yes for cooling, though dispenser features may be unavailable. We repair the wiring or module, quote first in writing and give a 30-day workmanship warranty. Ask us about it.
