Miele steam oven error codes
21 codes for DGC 7000-series combi-steam ovens (DGC 7440, 7640, 7840, 7780, 7785 and siblings), transcribed from the official documentation with page references.
Miele shows these as "F" messages in the display. Most are water-path problems you can clear yourself; a repeat after the fix means a service call.
| Code | What it means | Likely cause | What to do | Service? |
|---|---|---|---|---|
| F10 | Water intake problem from the tank. | The suction hose in the water container is not inserted correctly or is not vertical. | Correct the position of the suction hose, then restart. | Owner fix |
| F11 | Water is not draining. | The drain hoses are blocked. | Clear the drain hoses. If the message returns, contact Miele Service. | Call service |
| F20 | Descaling is required. | Limescale build-up in the steam system. | Descale the oven (see "Cleaning and care" in the manual). If the fault message appears again afterwards, contact Miele Customer Service. | Owner fix |
| F44 | Technical fault. | Internal electronics fault. | Switch the oven off and on again. If the same message appears again, contact Miele Service. | Call service |
| F55 | Safety shut-off after maximum run time. | The oven ran a function for longer than its maximum permitted time and switched itself off. | Switch the oven off and on again; it is immediately ready for use. | Owner fix |
| F94 | No water reaching the plumbed inlet (DGC 7785 and other plumbed models). | Inlet hose trapped or kinked, water supply valve not opened, or a float switch in the water container is stuck. | Free the hose and open the supply valve, then restart. If it returns after fixing the cause, contact Miele Service. | Call service |
| F190 | Water intake valve fault (plumbed models). | Can occur if the control panel is opened or closed while water is being drawn in. | Confirm with OK and continue. If the message appears again, contact Miele Service. | Call service |
| F196 | General fault, often the drain filter. | The drain filter is not inserted correctly, or an internal fault. | Turn the oven off, re-seat the drain filter, turn it back on. If it recurs, contact Miele Service. | Call service |
| F1 | Continuous audible signal after the oven is switched off (function knob at 0); residual water cannot be pumped out. | The water container used to collect pumped-out residual water is not in the appliance. | Push the water container fully into the appliance. | Owner fix |

If the fault persists, contact Miele Service. | Call service |
| F12 | The current cooking program is interrupted; water is not getting into the steam oven. | The water intake valve is not open; the filter in the water intake is blocked; or the water intake hose is faulty. | Open the water intake valve and restart, or clean the intake filter. If the intake hose is faulty, turn the oven off, close the water supply valve and contact Miele Service (or a plumber). | Call service |
| F13 | The temperature in the oven is too high. | The water intake valve is not fully open, or the water nozzle is scaled up or clogged. | Open the water intake valve fully and restart, or descale the nozzle using the same procedure as for F05. If the fault persists, contact Miele Service. | Call service |
| F14 | Water inlet symbol: too little water is reaching the steam generator. | Too little water is getting into the steam generator. | Turn the steam oven off and back on. If the message appears again, switch the oven off and contact Miele Service. | Call service |

Before you call Miele
- Refill and re-seat the water tank, and straighten any inlet or drain hose you can reach.
- Run the descale program if the oven has one, with the manufacturer's descaler, not vinegar.
- Switch the oven off at the wall for a minute and back on. One power-cycle is in nearly every manual; repeated resets are not.
- If the same code returns, note it with the serial number and book service. Every sensor, probe, fan or board code above is listed by Miele as a service call.
