Hotpoint F07 fault codewhat it means and how to fix it
The flow turbine reported no water arriving when the machine had in fact filled. The measuring device rather than the water supply.

Get a qualified appliance engineer to look at your Hotpoint F07
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 F07 means
F07 is described by Hotpoint as a damaged water turbine, and the detail underneath is what makes the code make sense: the turbine has given no signal indicating entry of water, even though fill has effectively been completed. So the machine filled up. It knows it filled up. The device whose job is to say so said nothing. That device is a flow meter, and it is a small paddle wheel in the inlet path with a magnet in it. Water passing through spins the wheel, a sensor counts the pulses from the magnet, and the machine adds them up to work out how many litres have gone in. It is a genuinely elegant piece of design, because it lets the appliance measure a volume rather than guessing at one from a timer, which is how it can fill accurately whatever your water pressure happens to be.
What it also means is that the machine has two independent ways of knowing about water — the turbine counting it in, and a pressure switch confirming the level reached — and this code is what you get when those two disagree in one particular direction. That is worth understanding because it explains why F07 is not a water supply problem, and why working through your tap and hoses will not help.
Contrast it with the codes either side. F06 is a fill timeout: no water arrived and the machine says so, and Hotpoint invite you to check the tap and the hose. F05 is the mirror image of F07: the turbine counted the water in but the pressure switch never confirmed the level. F07 is the turbine failing to count water that demonstrably arrived. All three are about filling and only one of them is about your plumbing.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Flow meter paddle jammed | Grit or scale from the mains stopping the wheel turning. The water still flows past it, so the machine fills while the count stays at zero. | Common |
| Flow meter sensor or magnet failed | The wheel turns and nothing registers. Hotpoint’s word for the whole assembly is the turbine, and this is the electrical half of it. | Common |
| Wiring or connector at the flow meter | A pulse signal is easily lost to a corroded pin in a damp cabinet, and it reports identically to the device itself having failed. | Occasional |
| Debris carried in after plumbing work | Grit disturbed in the supply pipework and swept into the meter. Worth mentioning if anything was done to the plumbing shortly before this appeared. | Occasional |
| Control board input failed | The board no longer counting pulses that are being sent. Rare, and established only after the meter and its wiring are proven good. | Rare |

What it costs to fix
Typical repair cost
£90–£180
Typically £90 to £170 fitted. A flow meter is an inexpensive component, so the labour and the call-out are most of it.

Common questions about Hotpoint F07
Should I check my tap and hoses?
Not for this code. F07 is the machine saying water arrived but the device that counts it stayed silent, so your supply has already proved itself. The code to work through the tap, the hose and the inlet filter on is F06, which is a fill timeout.
What actually is the turbine?
A flow meter — a small paddle wheel with a magnet in it, sitting in the inlet path. Water spins it, a sensor counts the pulses, and the machine converts the count into litres. It is how a dishwasher measures the water it takes in rather than timing it and hoping.
How does this differ from F05?
They are two halves of the same disagreement. F07 is the turbine reporting nothing when water did arrive. F05 is the turbine having counted the water in while the pressure switch never confirmed the level was reached. The machine cross-checks two devices, and which one it doubts decides which code you get.
Is it an expensive repair?
It is at the moderate end. A flow meter is a modest part, and most of the cost is reaching it and the visit itself. It is well worth asking whether the meter alone is being replaced or a whole inlet assembly, because those are different numbers.
