Error code
Whirlpool Washing Machine Error Code F23
Pressure switch or anti-flood fault The most likely cause is pressure sensor reading outside range. Check first: check visible fill and drain hoses for obvious restrictions.
Quick answer
F23: Pressure switch or anti-flood fault
Meaning
Pressure switch or anti-flood fault
First safe check
Restart only once after checking the appliance is not overfilled or leaking.
Stop if
Stop if the code returns, water reaches electrics, there is burning smell, the appliance trips power, or the next step would require internal access.
Who to call
Contact a qualified technician if F23 returns after safe visible checks, the appliance cannot complete a short test, or diagnosis would require internal access.
Medium severity: check safely and stop if it returns. Disconnect power before checking accessible parts where the appliance guidance says to do so.
Fix time
5-20 minutes for safe visible checks
Difficulty
Easy to moderate
The useful first pass is to confirm simple visible causes before assuming a failed internal component.
Expected outcome: A simple external cause may clear after one short test. Repeated F23 means the appliance needs closer diagnosis.
What does this error code mean?
Whirlpool washing machine F23 usually means pressure switch or anti-flood fault. The exact cause can vary by model, so use this page as safe fault-code context rather than a confirmed diagnosis of one failed part.
Start with the checks that do not require dismantling the appliance: power, water, drain, door, filters, load, or airflow depending on the fault family. If the code returns after one sensible retry, the safer next step is a qualified technician or the manufacturer's authorised service centre.
This code sits in the pressure level fault family, so checks should stay focused on that system before broader part replacement is considered.
Symptoms users may notice
- Water level may look too high, too low, or unstable.
- The programme may stop during filling or draining.
- The code may appear with overfill or drain warnings.
Why is this happening?
- Pressure sensor reading outside range
- Blocked pressure chamber or hose
- Overfill, underfill, or unstable water-level signal
- Control board not reading the level signal correctly
What this usually points to
This code sits in the pressure level fault family, so checks should stay focused on that system before broader part replacement is considered.
How to fix this safely
- Restart only once after checking the appliance is not overfilled or leaking.
- Check visible fill and drain hoses for obvious restrictions.
- Do not blow into pressure tubes or open panels.
- Arrange service if the water level looks wrong or the code returns.
Can I fix this myself?
YesYou can make the visible checks listed above, but do not dismantle the appliance or test live electrical parts.
Safety boundary: Stop if the code returns, water reaches electrics, there is burning smell, the appliance trips power, or the next step would require internal access.
What not to do
- Do not keep clearing the display with repeated resets.
- Do not remove panels, test live wiring, bypass sensors, or force stuck parts.
- Do not continue normal use if there is leaking, overheating, burning smell, or electrical tripping.
Common misdiagnoses
- F23 can be mistaken for a single failed component, but the same display can be triggered by supply, sensor, wiring, control, or usage conditions depending on the model.
Reset steps
- Switch the appliance off and wait briefly before restarting only if the manual allows it.
- Run one short test after completing the safe visible checks.
- Stop and arrange help from a qualified technician if the code returns.
Intermittent vs persistent faults
A one-off F23 may follow a temporary condition. Repeated or immediate returns should be treated as persistent and escalated.
When to call a technician
Contact a qualified technician if F23 returns after safe visible checks, the appliance cannot complete a short test, or diagnosis would require internal access.
Safety warning
Disconnect power before touching accessible hoses, filters, doors, or panels. Do not work on live electrical parts or sealed components.
