F18
Hotpoint F18 on a washing machine: internal data error
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On a Hotpoint washing machine, error code F18 means an internal data error where some or all display and control functions stop working. Unplug the appliance from the mains for at least 2 minutes, plug it back in, wait 30 seconds and try starting a cycle; if F18 stays, book an engineer.
Safety first
Stop and check this first
- Always switch off and unplug the washing machine before any cleaning or maintenance work; never remove the top panel or open the control console yourself as internal components carry mains voltage.
- If F18 stops the machine mid-cycle, wait until the locked door indicator symbol turns off before opening the porthole door and never force the handle.
Safe checks you can perform
- Unplug for at least 2 minutes, wait 30 seconds after reconnecting and retry
- Verify the mains plug is fully seated in a working wall socket
- Check Key Lock, Demo Mode or Reset to Factory Default if buttons stay locked
Leave these tasks to a qualified professional
- Do not attempt this professional task: Check that all internal wiring connections between display and control are secure
- Do not attempt this professional task: Diagnose and reprogram or replace the electronic control or display module

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Check that all internal wiring connections between display and control are secure
What they doWith the washing machine switched off and unplugged from the mains, the Hotpoint Service engineer inspects the wiring harness and connectors linking the display interface and main electronic control board to ensure all connections are secure.
They must show youthe checked internal connectors and the control panel responding to all function selections without F18.
In writingcode F18, the inspection of the display-to-control connections and the functional test result.
Diagnose and reprogram or replace the electronic control or display module
What they doIf F18 remains after the 2-minute unplug reset and connection check, the engineer diagnoses the internal data fault on the control board or display module and reprograms or replaces the faulty unit using the model codes inside the door.
They must show youany replaced module and a wash cycle starting and running with all display functions working.

Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Unplug for at least 2 minutes, wait 30 seconds after reconnecting and retry
- Who:
- you.
- How:
- switch off the washing machine, unplug it from the mains supply for a minimum of 2 minutes as Hotpoint specifies for F18, reconnect the plug, wait 30 seconds and press ON/OFF to try starting the machine again.
- Result that matters:
- clearing transient internal data errors and testing whether the display and functions recover.
- If F18 disappears and all display and programme functions work again, the internal data error has cleared.
- If F18 remains on the display or functions still do not work, move on to checking the power socket and panel locks.
- Evidence to keep:
- how long the machine was unplugged and whether F18 returned after the 30-second wait.

Verify the mains plug is fully seated in a working wall socket
- Who:
- you.
- How:
- check that the power plug is inserted fully into the wall socket to make solid contact and that there is stable power in the house, as listed in the Quick Guide troubleshooting table.
- Result that matters:
- ruling out a poor socket contact causing power dips and internal data errors.
- If the plug was loose in the socket, seat it firmly and repeat the 2-minute unplug reset.
- If the wall socket and plug are secure, check whether a panel lock or settings state is active.
- Evidence to keep:
- whether the mains plug was firmly seated and whether the display lights up normally.

Check Key Lock, Demo Mode or Reset to Factory Default if buttons stay locked
- Who:
- you.
- How:
- if the display clears F18 after unplugging but functions are still not selectable, check that 'KEY LOCK' is not shown (hold the Key Lock button for 3 seconds to unlock) or 'DEMO' is not active, or hold button G (Options/Settings) for 3 seconds, select 'FACTORY DEF.' and hold confirm for 5 seconds.
- Result that matters:
- making sure unresponsive functions are not caused by Key Lock, Demo Mode or a stuck setting.
- If unlocking the panel or restoring factory settings restores normal selection, confirm your language and test a wash cycle.
- If the spanner icon and F18 persist and functions remain dead, switch off, unplug and book a Hotpoint Service engineer.
- Evidence to keep:
- the exact display state and the model/serial codes on the adhesive label inside the porthole door.

What it means
In Hotpoint UK's official Washing Machine Error Codes Troubleshooting Guide, F18 is defined as an internal data error, with the symptom that some or all display or control functions do not work on the washing machine. Hotpoint advises disconnecting (unplugging) the appliance from the mains supply for a minimum of 2 minutes, reconnecting the supply, waiting 30 seconds and trying to start the machine again (the official Hotpoint NLCD 10448 WD AW EU Quick Guide likewise advises switching off and unplugging when the spanner symbol and an error code appear). Seeing F18 on its own never proves that a control board is broken.

- Key Lock, Demo Mode or settings state blocking button inputPossible
If the screen wakes after a power reset but buttons still do not respond, the Quick Guide points to checking Key Lock ('KEY LOCK'), Demo Mode ('DEMO') or running a factory default reset.

- Loose internal connection or persistent electronic module faultLess common
Hotpoint notes that if an error code persists after the 2-minute mains reset, internal connections and control components need to be checked by a Hotpoint Service engineer.
