Miele Dryer Error Code F55

F55 means the dryer's overriding time limit of approximately 180 minutes has been exceeded during a residual moisture program without the sensors detecting that the laundry reached the target dryness level. The control system stops the cycle automatically at this hard limit to prevent the machine from running indefinitely. The error points to a condition that slowed drying well beyond normal, such as overly wet laundry, a restricted air path, or an oversized load.

You should not restart the dryer on the same load without first identifying and correcting the underlying cause. The machine stopped as a protective measure, and simply restarting without changes will likely result in the same error or incomplete drying. Once you have addressed the root cause, such as clearing a blockage or reducing load size, the dryer is safe to operate normally.

If the fix involves only cleaning the lint filter, clearing the duct, or adjusting washer spin settings, there is no parts cost and minimal labor involved. If moisture sensor replacement or exhaust duct work is needed, parts and labor costs can range from around $100 to $400 or more depending on the specific components involved and local service rates. Getting a diagnostic assessment from a Miele-authorized technician before committing to repairs is recommended.

Start by cleaning the lint filter and checking the exhaust duct for blockages or kinks. If the laundry was transferred directly from the washer, re-spin it on a high spin speed setting and reduce the load size before trying again. If the error returns after addressing those factors, inspect the moisture sensor bars inside the drum for residue buildup and wipe them clean. Persistent errors after all of these steps may indicate a component fault requiring professional diagnosis.

Resetting the machine may clear the error code from the display, but it will not resolve the underlying condition that caused the time limit to be exceeded. If you restart the dryer on the same load under the same conditions, the F55 code will return once the 180-minute limit is reached again. Address the root cause before resetting and restarting.
