Whirlpool F02 on a washing machine
The motor speed sensor is not reporting back to the control board.
The same code appears on Hotpoint, Indesit and Ariston machines — they share the same control platform.

What F02 actually means
The tacho coil on the motor tells the board how fast the drum is actually turning. When that signal disappears the board stops rather than risk driving the motor blind. The drum often will not turn at all, or turns briefly and then stops with the code showing.
Before you start
Electrical safety: Motor work means working close to mains wiring and a capacitor that can hold charge. Unplug and leave the machine isolated before any panel comes off.
What causes it, most likely first
Failed tacho coil
Most likelyThe small coil on the end of the motor that generates the speed signal goes open circuit. A common and relatively inexpensive failure on this platform.
Drive motor£60–£160 for the partEngineerWorn motor carbon brushes
CommonBrushes worn to the stub make intermittent contact, so the motor stutters and the speed signal becomes erratic enough for the board to fault out.
Motor carbon brushes£8–£22 for the partDIY with careLoose or corroded motor connector
CommonThe motor plug works loose with vibration or corrodes in a damp under-counter position, breaking the tacho signal path.
Wiring loom / connector£10–£45 for the partEngineerSeized drum or jammed object
OccasionalA drum that physically cannot turn produces no speed signal, so a mechanical jam presents as a sensor fault.
How to check: With the machine unplugged, turn the drum by hand — it should spin freely.
Control board fault
OccasionalThe board section that reads the tacho signal fails. Diagnosed by elimination once the motor and wiring test good.

How to fix it, step by step
Unplug and turn the drum by hand
Rotate the drum through several full turns. If it is stiff, grating, or will not move, you have a mechanical problem rather than a sensor one — mention that when you book.
5 minPower-cycle and try an empty spin
Switch off at the wall for a minute, restore power, and run a spin-only cycle with the drum empty. Note whether the drum moves at all before the code appears.
10 minBook an engineer with the code
F02 points straight at the motor, its brushes and its wiring. Quoting it means the engineer arrives with brushes and a meter rather than diagnosing from scratch.
5 minAsk for the full quote before work starts
Brushes are cheap; a motor or a board is not. On a machine over about seven years old, ask what the total will be and compare it against a graded replacement before agreeing.

Parts you might need
Typical UK prices for the part alone, before fitting. Worth knowing before you accept a quote — the part is often a small share of what a repair is priced at.
Motor carbon brushes
Two sacrificial carbon blocks that carry current into a brushed motor. They wear down over years and are a cheap, planned replacement.
£8–£22Wiring loom / connector
Chafed wires and corroded connectors mimic dead components. An engineer will always check continuity before condemning a part.
£10–£45Drive motor
The motor that turns the drum. On most machines a genuine replacement costs enough to trigger a repair-or-replace decision.
£60–£160Main control board (PCB)
The appliance brain. Genuine boards are expensive and often need configuring to the model, so this is rarely a DIY part.
£70–£220
Worth repairing, or replace it?
At the top of this range the repair costs a significant share of a graded replacement, which typically starts around £200. Worth getting the quote first, then deciding — on a machine under about five years old a repair usually still wins.
