Fisher & Paykel ActiveSmart Refrigerator Code 42: Fill Tube Heater Current High

What Code 42 means

On Fisher & Paykel ActiveSmart Ice & Water refrigerators such as the E522BRXU, Code 42 means the ice maker fill tube heater, the nozzle heater, draws high current, pointing to a short. The heater keeps the fill nozzle from freezing. This code shows up in a technician's data readout, so you may notice only frozen water at the fill tube. The unit may show no code at all.

1. Unplug the unit for five minutes and restart. 2. Check whether ice is building up at the ice maker fill area, without chipping at it. 3. Keep the water supply on. 4. If ice or leaks appear, call us. Do not chip at the nozzle.

! Why to stop there

The heater is built into the ice maker fill area.
Excess current can overheat wiring.
We read the data and test the heater before quoting in writing.

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.
