CodeAppliancesFault / DiagnosticsRepair InstructionsAction

F5

Hob / Cooktop

Electronic Control Board (PCB) & Bus Communications

De Dietrich Piano Zoneless / Horizone / DPI Induction Cooktop: Induction power stage thermal overload F5; cooling fan cannot dissipate heat quickly enough, triggering thermal power foldback.

On De Dietrich cooktops utilizing Piano full-surface zoneless induction matrix, 16-level power modulation, and Boil function boilover prevention: Sustained maximum power boiling across all zones simultaneously with restricted under-counter ventilation channel.

Reduce cooking zone power levels. Open cabinet doors temporarily to exhaust hot trapped air. Ensure front cooling ventilation gap is unblocked. Clear the ceramic surface, turn off the dedicated breaker for 60 seconds, restore supply and touch the Key Lock sensor for 5 seconds.

F5

Refrigerator / Freezer

Refrigeration Compressor, Defrost Heater & PTC Relay

De Dietrich Prestige No Frost / DRS Multi-Zone Refrigerator: Evaporator fan motor feedback failure F5; fan motor does not achieve target operating RPM during cooling demand.

On De Dietrich refrigeration units featuring Prestige No Frost multi-sensor refrigeration, active preservation zone, and inverter compressor modulation: Heavy ice build-up impeding fan blades, seized motor sleeve bushings, or defective Hall-effect RPM feedback circuit.

Manually defrost evaporator cavity. Spin fan wheel by hand to verify free movement. Measure 12V DC power and frequency on Hall tacho wire during operation. Replace fan assembly. Touch and hold the Alarm Acknowledge and Quick Chill icons for 8 seconds until the ICS chime signals buffer reset, then release.

F6

Dishwasher

Water Level Pressure Switch & Air Dome

De Dietrich Quattro / Space / DFI Luxury Built-in Dishwasher: Continuous water entry / water level safety fault F6; water continues to rise after program attempts shut-off.

On De Dietrich dishwashers featuring Quattro 4-level hydraulic spray distribution, ICS turbidity assessment, and 42dB acoustic encapsulation: Mechanically stuck inlet valve seat, shorted triac on power board, or blocked pressure sensor hose.

Disconnect mains power and check if water stops entering (if yes, electronic triac short; if no, mechanical valve failure). Replace component. Press and hold Programme Selection and Start buttons for 5 seconds until all cycle lights illuminate steadily, then switch off power.

F6

Hob / Cooktop

Electronic Control Board (PCB) & Bus Communications

De Dietrich Piano Zoneless / Horizone / DPI Induction Cooktop: Short-circuited IGBT power semiconductor F6; circuit breaker trips with an audible pop when zone is turned on.

On De Dietrich cooktops utilizing Piano full-surface zoneless induction matrix, 16-level power modulation, and Boil function boilover prevention: Collector-to-emitter semiconductor breakdown on IGBT due to voltage spike or thermal fatigue under load.

Disconnect cooktop from breaker. Disassemble power unit and test IGBTs on heatsink with multimeter on diode test (~0V = blown). Replace power module. Clear the ceramic surface, turn off the dedicated breaker for 60 seconds, restore supply and touch the Key Lock sensor for 5 seconds.

F6

Refrigerator / Freezer

Refrigeration Compressor, Defrost Heater & PTC Relay

De Dietrich Prestige No Frost / DRS Multi-Zone Refrigerator: Door display communication fault F6; user interface loses digital connection to the main power board.

On De Dietrich refrigeration units featuring Prestige No Frost multi-sensor refrigeration, active preservation zone, and inverter compressor modulation: Severed or pinched wires inside the top door hinge bushing, oxidized connector pins, or faulty transceiver on display PCB.

Inspect door hinge wiring harness: check each wire for breakages caused by door swinging. Clean multi-pin connectors with contact cleaner. Replace display module if wiring tests OK. Touch and hold the Alarm Acknowledge and Quick Chill icons for 8 seconds until the ICS chime signals buffer reset, then release.

F7

Hob / Cooktop

Drive Motor, Inverter & Tachometer Sensor

De Dietrich Piano Zoneless / Horizone / DPI Induction Cooktop: Cooling fan blocked or low RPM stall F7; electronic safety cuts zone power when fan fails to achieve operational speed.

On De Dietrich cooktops utilizing Piano full-surface zoneless induction matrix, 16-level power modulation, and Boil function boilover prevention: Grease accumulation seizing fan spindle, dislodged internal sound baffle, or open motor coil winding (~40–80 Ω).

Clean fan impeller blades and bearing spindle with alcohol. Measure motor coil resistance (~40–80 Ω). Verify free spin by hand. Clear the ceramic surface, turn off the dedicated breaker for 60 seconds, restore supply and touch the Key Lock sensor for 5 seconds.

F8

Hob / Cooktop

Electronic Control Board (PCB) & Bus Communications

De Dietrich Piano Zoneless / Horizone / DPI Induction Cooktop: Continuous pan sensing resonance failure F8; induction coil pulses loudly but cannot sustain stable magnetic field coupling.

On De Dietrich cooktops utilizing Piano full-surface zoneless induction matrix, 16-level power modulation, and Boil function boilover prevention: Cookware with non-uniform sandwich composite base, cracked resonance capacitor bank on power PCB, or burned Litz coil wire.

Switch to a solid heavy cast iron skillet to test coil coupling. Inspect resonance capacitors on PCB for bulging or scorch marks. Clear the ceramic surface, turn off the dedicated breaker for 60 seconds, restore supply and touch the Key Lock sensor for 5 seconds.

F9

Hob / Cooktop

Electronic Control Board (PCB) & Bus Communications

De Dietrich Piano Zoneless / Horizone / DPI Induction Cooktop: Control board EEPROM calibration checksum failure F9; factory power table values are corrupted and zones will not operate.

On De Dietrich cooktops utilizing Piano full-surface zoneless induction matrix, 16-level power modulation, and Boil function boilover prevention: Power line voltage surge corrupting non-volatile flash memory cells on touch microprocessor board.

Disconnect power circuit breaker for 15 minutes. Reconnect power and observe if calibration reloads; replace touch controller PCB if code persists. Clear the ceramic surface, turn off the dedicated breaker for 60 seconds, restore supply and touch the Key Lock sensor for 5 seconds.

F10

Oven / Microwave

Heating Element, Thermostat & Safety Fuse

De Dietrich Fascination Pyrolytic Oven stops during pyrolytic cycle and locks door, flashing error 'F10'.

Chassis temperature exceeded safe ceiling (overheat switch open) due to cooling turbine stall or obstructed air exhaust ducts.

Allow oven to cool 60 minutes. Check upper exhaust grille clearance. Test overheat limiter continuity (0 Ω). Reset mechanical thermostat button.

SAFE

Oven / Microwave

General System & Mechanical Integration

De Dietrich ICS (Intelligent Cooking System) / Fascination / Corium Pyrolytic Oven: Child safety control lock active SAFE; display shows 'SAFE' and oven controls are locked against accidental activation.

On De Dietrich ovens featuring ICS sensor-guided automated culinary cooking, PT500 platinum thermal probe (~540 Ω at 20°C), and 480°C Pyro-Turbo cleaning: User-activated child lock feature, or long accidental press on the Key pad or Clock icon.

Touch and hold the Key icon or Clock button firmly for 5 seconds until an audible beep confirms deactivation and 'SAFE' extinguishes. Rotate rotary knob to zero, disconnect power at the master breaker panel for 90 seconds, re-engage and validate time on the ICS interface.
