Miele Washer Error Code F24 — Pressure Switch / Water Level Sensor Failure
What this means
The F24 error code on Miele washers indicates the pressure switch (water level sensor) is malfunctioning. This switch monitors the water level in the drum by detecting air pressure through a small hose connected to the tub. A clogged pressure hose, a leaking hose connection, or a failed switch can prevent accurate water level detection, causing the washer to overfill, underfill, or refuse to start.
Alternate codes: F 24
Step-by-step fix
4 stepsReset the washer
Unplug the washer for 5 minutes and plug it back in. Run a cycle. If the error does not return, it was a momentary glitch in the pressure switch circuit.
An intermittent F24 code is often caused by a loose pressure hose rather than a failed switch.
Inspect the pressure hose
Unplug the washer and remove the top panel. Locate the pressure switch (a small round or rectangular device on the side or top of the tub) and trace the small rubber hose from the switch to the tub. Check for kinks, cracks, disconnections, or clogs.
Blow gently through the hose to check for blockages. Detergent residue and fabric softener can clog the hose over time.
Test the pressure switch
With the hose disconnected from the switch, blow into the switch port. You should hear a distinct click. Release and listen for another click. If there is no click, the switch is faulty. Test continuity across the switch terminals with a multimeter — the reading should change when you blow.
Make sure the hose connection to the switch is airtight. Even a hairline leak will give false readings.
Replace the pressure switch or hose
Replace the pressure switch if it does not click or fails the continuity test. If the hose was clogged or cracked, replace it. Reassemble and run a test cycle.
When reinstalling the hose, route it carefully to avoid kinks against the tub or other components.
When to call a professional
If the switch and hose are both good but the error persists, the control board may have a faulty sensor input. A Miele technician can diagnose the electronics.
