Choose what you notice. These are the issues covered by your appliance guide.
Use suitable fresh cold water. If filtered or demineralised water causes this, the manual allows mixing it 1:1 with still mineral water; check the hardness setting too.
Order a replacement tank; impacts may have loosened internal parts.
Contact Siemens service; the level sensor may be faulty.
A hardness setting that is too low can cause this.
Heavy steam during automatic calibration can be normal. Do not interrupt the calibration by opening the door.
The oven may not have completed calibration. In menu > Settings, reset Factory settings, save, then repeat first startup and calibration.
Vent steam, popping around frozen food, pump humming during or after use, and panel-opening clicks can be normal. Buttons can flash while condensation behind the panel evaporates.
Check whether other kitchen appliances have power and whether the oven circuit breaker is in order. Contact service if it remains unresponsive.
Allow the cavity to cool, then start the selected function again.
Read and follow the displayed instruction. Open and close the door once after a power cut so the appliance can check itself. If operation still will not start, contact Siemens service.
Briefly switch the oven's circuit breaker off and on, then disable demonstration mode in menu > Settings within three minutes. Save the setting.
Switch the oven off and on once. If the message returns, contact Siemens service and give the exact displayed code.
Check the oven's power supply and circuit breaker. If it still will not open, contact Siemens service.
If water remains in the tank, ask Siemens for help emptying it safely. Do not force the panel.
Contact Siemens service. Do not remove the lamp cover.
Keep cleaning to accessible glass, the seal in place and the condensate trough. Ask Siemens for help with pane or door disassembly; do not use the oven with damaged glass or a damaged seal.
The oven stops heating automatically after a long time with unchanged settings. Switch off, switch on and set the required function again. Set a cooking duration for long cooking.
When the oven asks you to rinse
Switch the oven on if needed and follow its rinse prompt. Open the panel, remove the tank, thoroughly rinse it, refill with water and refit. Close the panel and press start/stop.
When prompted again, repeat the tank rinse, refill, refit and start/stop sequence. Wait for the second rinse to end.
Empty and dry the tank and lid seal; let it dry with its lid open, refit it and switch off.
