Fisher & Paykel Top-Load Washer Code 105: Comms error time out between modules

What 105 means

On Fisher & Paykel AquaSmart and EcoSmart top-load washers like the WA37T26EW and WA42T26GW, and SmartDrive Phase 2 to 6 machines such as the GWL15, code 105 is a communications error timeout. The display module reported that it stopped hearing from the motor control module. It can also appear when the display is changed while the power is still on. Expect a stopped cycle and the number on the screen.

Common causes of 105

Display module lost contact with the motor control module
Display swapped or reconnected with the power still on
Damaged or loose wiring between the modules

✓ One safe check you can try

1. Press power off and unplug the washer for one minute. 2. Plug in again and run a short empty spin. 3. Look at the outlet and cord for damage, and skip any extension cord. 4. If code 105 shows again, stop and call us. Do not remove the display yourself, because reconnecting a display with power on can bring this code back.

! Why to stop there

Reconnecting boards with power applied can damage them
The link between modules needs testing with the machine opened and unplugged
The cause may be wiring or either board, and only testing shows which

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.

105105 questions

Why did code 105 appear after the display was changed?

A display reconnected or replaced while the washer was still powered can drop the link to the motor control module. Power-cycling after the swap sometimes restores it, but a check is wise.

What does the code actually report?

It reports a timeout: the display module waited for the motor control module and got no reply. It is a message about the electronics talking, not about water or load.
