Clean the fluff filter (inside the door) and the fine filter (door base).
Most Miele dryer fault codes you can wipe out with a 60-second power cycle and you're good to go. But here's the thing: if you skip cleaning the filters first, that code is just going to come right back. I see this constantly. Ignore a heating fault long enough and you'll trip the thermal cutout permanently, which means actual parts and actual money. Always clean the filters before you bother resetting.

How to Reset Your Miele Dryer
OK so here's the deal with Miele dryers. They're seriously well-built machines but they're also way pickier about lint than most brands I work on regularly. The control board logs faults and some of them, honestly, a simple power cycle just clears them. Others like F066 are hardware trips that won't budge no matter how many times you unplug and replug until you fix the actual part. Resetting is free and takes 2 minutes, so always start there, but know what you're actually dealing with.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Transient heating fault cleared by power cycle40%
Program stuck after power outage36%
Post-repair code clear24%
Symptoms You May Notice
An F-code sitting on the display (F066 and F63 are the two I see most often on these) and the machine just won't do anything, no spinning, no heating, nothing.
Dryer stops dead 20-30 minutes into a cycle, drum just stops turning, sometimes with a code and sometimes with nothing on the display at all.
You start it, it runs for maybe 5-10 minutes, then cuts out before finishing, and it just keeps doing that every time you restart it.
Machine won't start at all after a power outage, just shows the fault code on the display like it's waiting for you to do something.
Clothes keep coming out still damp because the dryer keeps interrupting itself mid-cycle and never actually completes a run.
Tools Required for Diagnosis

Diagnostic Checklist
Follow these steps in order. We start with the easiest external fixes before opening up the machine.
Did the reset not work?
If the problem comes back after following these steps, a component has permanently failed and needs replacement. Check the specific error code your dryer is showing:
Clean both filters first, the fluff filter inside the door and the fine filter in the door base drawer. Then press Start/Stop, unplug for 60 seconds, and restart. If F066 clears and doesn't come back, the thermal cutout is still good and the filter clog was the whole problem. But if F066 comes right back after restart, the thermal cutout itself has physically tripped and needs to be replaced. There's no button combination that restores a tripped thermal cutout. That's a $40-60 part and about an hour of work to swap out.
Does resetting a Miele dryer delete my settings?
No. A power-cycle reset clears the active fault flag and the stuck cycle state but doesn't touch your programmed settings, temperature preferences, or drying level calibration. All that's stored in non-volatile memory. The only thing that actually resets is the fault.
My Miele dryer keeps showing a fault code every few weeks. Why does it keep coming back?
Because something's actually wrong and you're just clearing the symptom each time. The three most common reasons I see for repeat faults: the exhaust vent outside is partially blocked so the dryer always runs too hot, the fine filter in the door base hasn't been properly cleaned and is still restricting airflow even if it looks OK, or there's a failing part like an NTC temperature sensor getting flaky. If you've reset the same fault three times in a month, stop resetting and start actually diagnosing the root cause.
What's the difference between pressing Start/Stop and unplugging the dryer?
Pressing Start/Stop cancels the active program and clears the immediate program state, but the fault code stays in memory. Unplugging for 60 seconds does a full power-cycle which flushes the volatile memory and clears transient fault flags. For most fault situations you need both. Press Start/Stop first, then unplug. If you just unplug without pressing Start/Stop first, some Miele models will try to pick up where they left off when you plug back in, including the fault state, which kind of defeats the point.
Can I reset a Miele dryer without unplugging it?
Sometimes pressing Start/Stop is enough for really minor transient faults. But for anything with an actual fault code showing, you want the full 60-second power cycle to make sure the control board fully resets. Some techs use a service mode reset sequence if they're already in the machine doing other work, but for a homeowner the unplug method is simpler and works just as well.
How often should I clean the Miele dryer filters to avoid fault codes?
Fluff filter: every single load. That's not an exaggeration, Miele actually says this in their documentation and they're right about it. The fine filter in the door base: every 5-10 loads, or at least once a month. And the condenser if you've got a heat pump model needs attention every few months too. I replaced three thermal cutouts just last week and every single one of those customers admitted they hadn't touched the fine filter in over a year. Clean filters mean no overheating, no overheating means no fault codes. That's really the whole story.
