Fisher & Paykel Top-Load Washer Code 106: Display to motor control communications error

What 106 means

On Fisher & Paykel AquaSmart and EcoSmart top-load washers such as the WA37T26EW and WA42T26GW, and SmartDrive Phase 2 to 3 and Phase 5 machines, code 106 means the display module found an error in communications with the motor control module. The two boards exchange messages during every cycle, and a bad exchange stops the washer. Other communication codes, including 104 and 108, refer back to this one.

Common causes of 106

Error in the data link between display module and motor control module
Poor connection or damaged wire in the harness between them
One of the two modules failing to answer properly

✓ One safe check you can try

1. Stop the washer and unplug it for a full minute. 2. Plug it back in, close the lid, and start a quick spin cycle. 3. Check that nothing is stuck on the control panel and the panel is dry. 4. If the code persists, leave the washer unplugged and book service. We test the link with the power disconnected first.

! Why to stop there

Both modules share the link, so either could be the cause
A harness check means opening panels near mains power
Replacing the wrong board costs money and leaves the washer broken

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.

106106 questions

Is code 106 related to other codes?

Yes. Codes 104 and 108 point back to 106 because they describe the same kind of display to motor control communications problem, seen in slightly different ways.

Can moisture cause code 106?

Moisture on a control panel or connector can disturb the link. Keep the panel dry and let the area air out, but if the code persists the electronics need testing.

What will the technician check?

The harness and connectors first, then each module. We explain the finding and quote the price in writing before replacing anything.
