What F82 Means
F82 is an over-temperature problem on the coffee and hot-water heater: Miele’s documentation defines it as the heater staying above 170°C for two minutes. That is well past brewing temperature, which is why the machine shuts the function down rather than continuing.
Common Causes of F82
- Heater NTC defective, so the control cannot see the real temperature
- Heater fuse blown, which Miele notes may also have damaged the NTC
- Heater element itself defective
- Wiring or plug problem in the heater circuit
🔧 One Safe Check You Can Try
Switch the machine off and leave it off. Do not keep restarting it to see whether it will make one more coffee — the problem is the machine reporting that its heater ran far hotter than it should have, and repeated attempts simply repeat that.
⚠ Why You Shouldn't Go Further Than That
- Miele’s documented remedy for a blown fuse is to replace both fuses and the NTC together, because the sensor is likely to have been damaged by the same event.
- An over-temperature problem in a machine that pumps water past a heating element is not a code to reset around.
- The specified NTC has defined resistance values at set temperatures, and fitting a sensor that does not match that curve leaves the protection ineffective.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
