Fisher & Paykel Top-Load Washer Code 104: Display and motor control communications timeout

What 104 means

On Fisher & Paykel AquaSmart and EcoSmart top-load washers such as the WA37T26EW and WA42T26GW, and on SmartDrive Phase 2 to 6 models like the GWL11, code 104 means the display module detected a communications timeout with the motor control module. The two boards stopped talking to each other. The washer shows the number and the cycle will not continue normally. It is closely related to code 106.

Common causes of 104

Communications link between display module and motor control module timed out
Loose or damaged wiring between the two modules
A mismatched or failing motor control module

✓ One safe check you can try

1. Stop the cycle, unplug the washer for a full minute, and plug it back in. 2. Run a short drain and spin with nothing inside. 3. Check that the cord is fully seated and not shared with a power strip. 4. If code 104 returns, leave the washer off and book a visit. The wiring between modules is behind panels that we open with the power disconnected.

! Why to stop there

Communication problems come from wiring or one of the boards, and each needs testing to tell apart
Swapping modules by guesswork can make the mismatch worse
The harness is inside the cabinet near line voltage

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.

What is a communications timeout on a washer?

The display module and the motor control module pass messages back and forth. Code 104 means one stopped answering in time, so the washer cannot carry on with the cycle.

Is code 104 the same as code 106?

They are related. Both report a failed conversation between the display and motor control modules. A technician reads which one appears and tests the link and both boards.

Will you tell me the price first?

Yes. We quote in writing before any work, and repairs carry a 30-day workmanship warranty.
