Hotpoint F01 fault codewhat it means and how to fix it
Anti-flooding overflow. The one code in the Hotpoint list that offers no owner check at all — it goes straight to an engineer.

Get a qualified appliance engineer to look at your Hotpoint F01
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 F01 means
Check the shape of your code before you read any further, because this is the one place where the two Whirlpool-group code systems flatly contradict each other. This page is about F01, written with a leading zero, on the two-digit system used by Hotpoint and Indesit. On the single-digit system that many Whirlpool-badged machines use, F1 — or the START lamp flashing once — is not a flood at all. It is a frost warning, and the manufacturer’s instruction for it is to pour half a litre of warm water into the bottom of the machine. Doing that because you read this page would be a bad afternoon.
If your machine shows a single digit or flashes one lamp a countable number of times, stop here and check your own manual. With that settled: Hotpoint give F01 as anti-flooding overflow, which means the machine’s flood protection has tripped. Water has reached somewhere it should not be, and the machine has shut the cycle down rather than carry on. Something worth noticing about how Hotpoint handle this code. Of their thirteen dishwasher faults, two come with a check they invite you to make — the drain fault and the water supply fault. The other eleven go to an engineer, and F01 is at the top of that list with no owner step whatsoever. That is a deliberate editorial position from a manufacturer who elsewhere on the same page encourages you to fix the machine yourself, and it is the clearest signal they give about which faults they consider yours.
What F01 will not do is respond to the advice you will find everywhere online for anti-flood codes, which is to tip the machine onto its back or side to drain the base and reset the float. It clears the warning. It does not touch the leak that filled the base in the first place, it takes away the only thing standing between a slow leak and your kitchen floor, and it moves water into parts of the machine designed to stay dry. A dishwasher sits plumbed into the mains under a worktop and runs unattended overnight. The flood protection is not the problem.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Internal hose or joint leaking | Water escaping inside the cabinet and collecting in the base where the float detects it. Common and often an inexpensive part. | Common |
| Door seal perished | Water running down the inside of the door and pooling underneath rather than escaping visibly onto the floor. | Common |
| Sump or tub leaking | A split or a failed seal at the bottom of the machine. The serious end, and it needs finding before anyone can price it. | Occasional |
| Overfilling caused by a fill fault | Water arriving faster than the machine can account for and going over the top of the tub, which triggers the flood protection rather than a fill code. | Occasional |

Typical repair cost
£90–£280
Around £90 to £170 for a hose, joint or door seal. Sump or tub work runs higher, and on an older machine may not be worth doing.

Common questions about Hotpoint F01
What should I do right now?
Turn off the tap feeding the machine, then switch it off at the wall. Water first, because it keeps arriving whether the machine has power or not. Then book the engineer. Worth being straight about this: turning off the water and power is our advice, not Hotpoint’s. Their entire published instruction for a flood code is to ring the customer service centre — no tap, no power, no suggestion of stopping using the machine. Beko, Bosch, Miele, CDA and Lamona all tell owners to isolate on a leak code. Hotpoint and Indesit do not, and we think that is wrong.
My machine is a Whirlpool showing F1. Is this my page?
Almost certainly not, and it matters. On the single-digit system that many Whirlpool-badged machines use, F1 — or the START lamp flashing once — is a frost warning, and the published remedy is to pour half a litre of warm water into the bottom of the machine. That is the opposite of what you would want to do about a flood. This page covers F01 with a leading zero, on the two-digit system. If yours shows a single digit, or you are counting flashes of one lamp, go to your own manual.
Can I tip it up to drain the base tray?
No, and it is the most widely shared dishwasher advice on the internet. Draining the tray silences the warning without touching whatever filled it, and it disables the protection. It is removing the smoke alarm because it keeps going off.
There is no water on the floor. Is it a false alarm?
Usually not. The float sits in the base precisely so it catches water before it reaches your kitchen. A dry floor means it did its job, not that nothing is wrong.
My machine has no display. How do I know it is F01?
F01 is LED 6 lit on its own, with 7, 8 and 9 off — the pattern for 1. Do not count flashes; the lights hold a steady state. Any light blinking quickly is just drawing your attention and means nothing.
Does this code mean my machine is part of the safety notice?
No, they are separate things. The 2005 to 2015 Hotpoint and Indesit notice concerns an electrical component that can overheat, and Hotpoint do not say which one. It is not stated to be connected to the flood protection. If your machine is from those years, run it through the model checker anyway.
