| Code | Fault / Diagnostics | Appliances | Action |
|---|---|---|---|
| E10 | Info: Heat transfer too low, deposits on heater | Dishwasher | |
| E 011 | Activation continue d'une touche Info: Touche bloquée; Bouton poussoir ne s'ouvre pas | Oven | |
| E:11 | NTC resistance values outside permissible range / Operation without heating Info: NTC resistance values outside permissible range, interrupted connection or connector. | Dishwasher | |
| E011 | Oven carriage with soft-close device does not close correctly, allowing hot, humid fumes to enter the switch compartment and damage electronic components. Info: The Z-rail of the oven carriage brushes the support plate, the support plate of the soft-close device is bent up (not attached with all hooks), pins slip out of the soft-close device/emergency pull-out holder or are bent, a burr causes the damper to stick, or the downward cranked lower end of the U-rail is bent up. | Oven | |
| E11 | Info: NTC resistance values outside allowed range; Cable or connector cut | Dishwasher | |
| Er 11 | A button is deactivated. Info: Continuous pressing of a button for 10 seconds. 1 Elite Techs Verified | Oven | |
| E:12 | Operation without additional drying system (applies only to appliances with zeolite drying system) Info: NTC - resistance values outside permissible range (not present on all appliances) | Dishwasher | |
| E:13 | L'apparecchio rileva una temperatura dell'acqua > 75 °C e spegne il riscaldatore Info: L'apparecchio rileva una temperatura dell'acqua > 75 °C e spegne il riscaldatore | Dishwasher | |
| E13 | Protection â no appliance fault Info: Water temperature too high (> 75°C) | Dishwasher | |
| Er13 | Sporadic failure of the control unit with error message Er13 Info: Software bug in older FD versions (up to FD 8011) or customer deactivating the buzzer (FD 8012 to 8101). | Cooktop | |
| E:14 | No impulses from flow meter or tachometric generator, though water is recognized/loaded (wash pump signals speed/amperage variations, cycle interrupted with drain) Info: Wash pump / No impulses from flow meter or tachometric generator | Dishwasher | |
| E14 | Erreur de remplissage sur un lave-vaisselle, l'appareil détecte l'eau mais ne peut pas mesurer la quantité. Sur un lave-linge séchant, erreur de la sonde de température du circuit de séchage. Info: Pour un lave-vaisselle: défaillance du capteur de débit (débitmÚtre) ou de son cùblage. Pour un lave-linge séchant: défaillance de la sonde de température NTC du conduit de chauffage ou de son cùblage. | Dishwasher | |
| E-15 | Water in the base tray or water tap symbol flashes. Info: Water in the base tray. Safety system triggers. | Dishwasher | |
| E:15 | Program interruption with intermittent drainage / Safety switch in bottom pan active, appliance does not turn off / Water in the lower tank after replacing the heating pump / Water in the floor pan but no channel can be detected Info: Safety switch in bottom pan active, appliance does not turn off / Leak in the transition between the sump and the tub / Water traces visible in the circulation pump area / Defective pump connection clamp / Bent contact in cables/connectors | Dishwasher | |
| E15 | Error E15, caused by leakage under the water softening system Info: Minimal leaks in the water softening system can lead to error E15 after many wash cycles. | Dishwasher | |
| Er 15 | Oven is too hot, heating elements switched off, oven locked. Info: The actual temperature exceeds 380°C. | Oven | |
| E 16 | ROM error detected Info: ROM â Fehler | Steam Oven | |
| E:16 | Water loading (impulses from flow meter) without solenoid valve control or appliance recognizes impulses from tachometric generator although no water is loaded (cycle interrupted with drain) Info: Water loading / Flow meter impulses without solenoid valve control or tachometric generator impulses without water loading | Dishwasher | |
| E16 | Info: Water inlet (flow sensor pulses) without fill valve power | Dishwasher | |
| E 17 | EEPROM error detected Info: EEPROM â Fehler | Steam Oven | |
| E:17 | Excessive water quantity according to flow meter or tachometric generator signals excessive water flow (cycle interrupted with drain) Info: Water loading / Excessive water quantity detected by flow meter or tachometric generator | Dishwasher | |
| E17 | Program interruption with drain Info: Water inlet too high according to flow sensor | Dishwasher | |
| E:18 | No impulses from flow meter or scarce/absent water passage signalled by tachometric generator (intermittent drain pump operation, cycle interrupted) Info: Water loading / Scarce or absent water passage signalled by tachometric generator | Dishwasher | |
| E18 | Wait for water inlet. Program interruption with drain Info: Water inlet too low or absent according to flow sensor | Dishwasher | |
| E:19 | Additive fault / Heat exchanger valve fault / Program ends Info: Additive defective; Heat exchanger valve defective; Lines interrupted | Dishwasher | |
| E19 | Water in the base tray Info: Appliance leaks at the basket rollers, as these are not sufficiently tightened from the factory (upper basket and/or 3rd loading level). | Dishwasher | |
| E:20 | Erroneous circulation pump resistance values / Program termination Info: Open circuit or short in pump wiring. | Dishwasher | |
| E20 | End of program Info: Circulation pump fault; Incorrect circulation pump resistance values | Dishwasher | |
| E:21 | Circulation pump blocked / Program termination Info: Foreign objects or mechanical issue with the pump. | Dishwasher | |
| E21 | End of program Info: Circulation pump blocked | Dishwasher |
