What F193 Means
F193 records a short circuit in the bottom-heat Pt1000 temperature sensor or its harness. The control reads an impossibly low resistance and stops trusting the bottom element’s temperature feedback.
Common Causes of F193
- Bottom-heat Pt1000 sensor internally shorted
- Harness insulation broken down against a hot surface
- Moisture bridging the sensor contacts after a spill or a steam cycle
🔧 One Safe Check You Can Try
Leave the oven off at the breaker until it has been looked at, and keep a note of whether food has been browning unevenly on the base — that history is genuinely useful to whoever attends.
⚠ Why You Shouldn't Go Further Than That
- A short circuit against a hot chassis is exactly the kind of problem that has already damaged the cable insulation, which is why Miele replaces the sensor and harness together.
- The bottom sensor lies under the cavity floor, and getting to it means dismantling parts of the oven that have to go back in the right order to keep the seal intact.
- Running an oven whose bottom-heat feedback is wrong risks the element being driven for longer than intended.
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.
