Hotpoint F15 fault codewhat it means and how to fix it
A heater control fault. Hotpoint scope this one to both washing machines and washer dryers, and either half can be the one that stalls.

Get a qualified appliance engineer to look at your Hotpoint F15
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.
What F15 means
Hotpoint title F15 a heater control fault and take the trouble to say it applies to washing machines and washer dryers both — the only code in their washing machine table where they spell the scope out in the affirmative rather than restricting it. The symptom matches: the machine is not heating water or pauses during a wash cycle, or it is not drying or pauses during a drying cycle.
Four symptoms, two circuits, one code. What separates control from the element itself is the part of the circuit doing the switching. An element is either intact or it is not, and Hotpoint publish F08 for that. Control is everything that decides whether mains voltage reaches the element: the relay on the board, the safety devices in series with it, and the wiring in between.
A control fault can leave a perfectly good element cold, and it can also leave one energised when it should not be, which is why the board stops the cycle rather than continuing. On a washer dryer the same code covers the drying heater, so the reader’s own observation about which half stopped is genuinely useful information to bring to the engineer. Hotpoint offer no owner steps for F15.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Heater relay on the control board | The switch that feeds the element. Relay contacts weld or fail open, and either way the board sees a heating circuit not doing what it was told. | Common |
| Thermal cut-out in series with the element | A safety device that has opened. It usually opens for a reason, so an engineer who simply replaces it without finding out why has not finished. | Occasional |
| Wiring between board and heater | Spade terminals at the element run hot and darken over years. A poor joint there reads as a control failure from the board’s side. | Occasional |

What it costs to fix
Typical repair cost
£120–£280
A thermal cut-out or a connector is at the cheap end. A board-level relay fault means a board, which pushes this toward £280 fitted and toward the conversation about whether the machine is worth it.

- F03Get it checkedThe machine cannot read the water temperature, so it stops rather than guess. Washing comes out cold or the dryer side will not run.Related: heating and temperature
- F07Get it checkedA dual-titled fault with one very distinctive symptom: the programme stalls and the pump keeps running. Hotpoint give no owner steps.Related: heating and temperature
- F13Get it checkedA washer dryer only code. The drying half cannot read its own temperature, so the machine washes normally and will not dry.Related: heating and temperature
- F05Get it checkedThe machine cannot pump out, so the door stays locked with water inside. Hotpoint treat it as an owner job, and two of their own documents agree on the causes.Related: same brand
- F06Get it checkedA door lock fault — and the one code on this machine with an open safety recall behind it. If yours was built between October 2014 and February 2018, check the recall before anything else.Related: same brand

Common questions about Hotpoint F15
The machine stops mid cycle rather than washing cold. Why?
Because the board would rather stop than run a heating circuit it cannot control. Hotpoint list pausing during the cycle as one of the four F15 symptoms alongside simply not heating, and which of the two you get depends on where in the programme the circuit was when the discrepancy appeared.
Which half has failed on my washer dryer?
You can usually tell and it is worth writing down. If the wash comes out cold, it is the wash heating circuit. If the wash is hot and the machine stops when drying should start, it is the drying side. Hotpoint use one code for both, so your observation is the only thing narrowing it down before the panels come off.
How is F15 different from F08?
F08 is the element itself, titled as a heater fault. F15 is the control around it. The distinction matters at the quoting stage: an element is a defined part with a defined price, while a control fault could be a relay on the board, a thermal cut-out or a connector, and those three are very different bills.
Is it safe to keep using it?
Hotpoint do not flag F15 as a safety code and it is not one. That said, a heating circuit the machine has judged uncontrollable is not something to work around by repeatedly restarting the cycle. If cold cycles complete, use those and get it looked at rather than trying to force a hot wash through.
