What this error means
Motor control board fault — the motor control module is not communicating correctly
The F01 error indicates a fault with the motor control board (also called the power module or inverter board) — the electronic module responsible for driving the drum motor. This is different from a motor failure: the control board itself has either lost communication with the main control board, detected an internal fault, or been damaged by a power surge. A wiring fault between the two boards can also produce this code.

Step-by-step
Symptoms to look for
- Machine will not start any programme
- Drum rotates erratically or at incorrect speeds
- Machine starts then stops immediately with F01 displayed
- Error appears immediately after selecting a programme
Diagnostic steps
Unplug the machine and press and hold the programme selector button for 10 seconds to discharge residual power from the control boards. Leave unplugged for a full 10 minutes. Plug back in and try a cold start.
With the machine completely unplugged, remove the rear panel by undoing the screws around its edge. The motor control board (power module) is a separate board from the main PCB — on most Hotpoint washing machines it is mounted near the motor at the lower rear of the machine, often in a grey or black plastic housing. Take photographs of all wiring connections before touching anything.
Locate every connector between the motor control board and the main control board, and between the motor control board and the motor itself. Each connector must be pressed firmly and evenly until it seats fully. Pull each one apart and press it firmly back in. Look for any pins that are bent, corroded, or have pulled back into the connector housing.
Examine the motor control board surface for any discoloured, bulging, or burnt components, scorch marks on the board surface, or evidence of moisture ingress — rust staining, watermarks, or corrosion on connector pins.
Trace the wiring loom from the motor control board to the drum motor. Look for chafed insulation where the loom passes near sharp metal edges, pinched wires, or connectors that are not fully engaged on the motor terminals.
Reconnect all wiring firmly, replace the rear panel and run a 30-degree programme from cold. If the machine completes it without F01, run two further cycles to confirm stability.
When to call an engineer
- Visible burnt components or scorch marks on the motor control board
- F01 persists on every cycle after full 10-minute power discharge and connector reseating
- Motor control board has been exposed to water ingress
- Motor wiring continuity confirmed but board still not communicating — board needs replacing
