Code 46 is a Phase 5 IW display EEPROM problem. The manual lists one action, replacing the IW Display Module.
Model compatibility: Fisher & Paykel reuses codes across series and model years, so 46 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
A Phase 5 Intuitive Washer display detected a problem with its internal EEPROM.
Who sees code 46
Only Intuitive Washers (IW) running Phase 5 have this entry. In the manual’s description, the Intuitive Display has found a problem inside its own EEPROM. EEPROM is a memory chip that holds on to settings while the power is off.
The entire entry
Primary source: the IW Display Module.
Action: have the IW Display Module replaced.
A second suspect part and any step for the user are both absent. Nothing else is listed.
What follows from it
Since the chip sits inside the display itself, there is nothing here for a homeowner to open, clean or adjust. The manual states no cause, and the entry is short. Its wording is “problem” rather than failure, with no further detail on the finding. Replacement is the one instruction.
Machines in the Phase 5 IW list
The booklet lists IW709, IW609 and IW509, IWL10 and IWM10, IWC09, IW710 and IW810, plus IWM09 and IWL09. Code 46 is not written for any washer outside the Intuitive range.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
