What a Miele dryer is like to work on
A T1 is a heat-pump dryer, which means no vent and a condenser doing the work an exhaust duct would do elsewhere. It also means the failure nobody notices: the heat exchanger fouls with lint, drying times stretch out gradually, and no error is ever shown. By the time somebody calls, it has usually been happening for a season.
Model lines we service
What we open one for
Taking far longer than it used to, with no fault shown
The condenser fouling with lint. It is a maintenance item on these dryers and it gets missed because there is no error and no obvious symptom other than creeping cycle times. Cleaning it usually restores the original performance.
Not heating at all
The heat-pump circuit or its controls — a different diagnosis entirely from a vented dryer, and not a heating element.
Water in the base or the tank not filling
The condensate pump or its float. These dryers collect the water they take out, and that path can block.
Parts and what they cost
Obtainable, at Miele pricing. The condenser is a maintenance job rather than a part, and it is the first thing we look at on a slow T1.
Most dryer jobs land between $150 and $350, parts included, and the $150 minimum service call is part of that rather than on top of it.
When to call Miele instead of us
Miele warranties run longer than most, so check yours before booking any independent repair — including ours. If it is still covered, Miele should be doing the work.
Answered
- Why does my heat-pump dryer take so long now?
- The condenser is almost certainly fouled with lint. It is a maintenance item that gets missed because nothing errors — cycle times just creep up. Cleaning it usually restores the original performance.
- Do these need a vent?
- No, which is why they can go where a vented dryer cannot. The trade-off is that the condenser takes on the job an exhaust duct would do, and it needs the same attention a duct would.
