What F31 / F42 (110 / Whirlpool-built front-load) Means
F31 and F42 are listed together on the Whirlpool-built 110-prefix front-load platform as motor control board failures. Both send a technician to the same place: the harness between that board and the drive motor first, and the board itself only once the wiring proves good.
Common Causes of F31 / F42 (110 / Whirlpool-built front-load)
- A failed motor control board
- The motor harness damaged, unseated or corroded at a connector
- A drive motor drawing more current than the board will supply
🔧 One Safe Check You Can Try
Describe what the drum does — nothing, a twitch, or a start that dies — because that detail narrows a harness fault against a failed board before the cabinet is opened.
⚠ Why You Shouldn't Go Further Than That
- Motor and board connections carry mains voltage, so the machine is isolated at the breaker before any of it is touched.
- Because a failing motor can take out a board, replacing only one of the two sometimes buys a very short reprieve.
- This board sits deep in the cabinet on a front-loader, which means moving a heavy machine out before work begins.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
