NTC Temperature Sensor & Thermistor

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: Wash tub NTC temperature thermistor open or short circuit i70; temperature measurement circuit inoperative.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: NTC sensor internal pellet open or shorted (nominal 4.8–6.0 kΩ at 20°C; ~1.2 kΩ at 60°C), broken wiring harness in door hinge bend, or plug loose.

Measure NTC resistance directly at sensor terminals (4.8–6.0 kΩ at 20°C). Check continuity of 2-wire harness through door hinge flex point. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
i80
Dishwasher
Electronic Control Board (PCB) & Bus Communications

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: EEPROM communication fault or configuration checksum error i80; control board memory read failure.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: Damaged EEPROM integrated circuit, unprogrammed replacement motherboard, or electrical surge corrupting stored parameters.

Reprogram 16-character hexadecimal configuration code in service mode. If memory fails to write or retains checksum error, replace main PCB. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
i90
Dishwasher
Electronic Control Board (PCB) & Bus Communications

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: User interface display board communication failure i90 with main EDW control motherboard.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: Broken data wire in door harness flex zone, loose ribbon connector on display backplate, or missing 5V DC supply rail from main board.

Inspect wiring harness where it bends under door hinge. Test continuity of each wire with multimeter. Verify 5V DC rail at UI plug. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
iA0
Dishwasher
Drive Motor, Inverter & Tachometer Sensor

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: Lower spray arm rotation sensor missing pulses iA0; lower wash arm is stalled or rotation blocked.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: Tall plates, cutting boards, or cutlery handles protruding through basket blocking spray arm, missing arm magnet, or defective Hall sensor.

Rearrange lower basket loading so dishes do not contact spray arm. Inspect lower spray arm tip to confirm embedded magnet is present. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
iB0
Dishwasher
General System & Mechanical Integration

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: Turbidity optical sensor calibration failure iB0; clear water optical baseline out of specification.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: Grease film or milk residue coating turbidity sensor optical prism in sump, failed infrared emitter diode, or detached turbidity sensor harness.

Remove sump filters and clean optical prism window with alcohol wipe. Measure 5V DC supply at turbidity plug. Replace sensor if cloudy. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
iC0
Dishwasher
Electronic Control Board (PCB) & Bus Communications

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: User interface logic protocol mismatch iC0; communication packets rejected between UI and motherboard.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: Incompatible display board revision fitted, corrupted communication baud-rate settings in EEPROM, or electrical interference on bus lines.

Check PNC spare part compatibility on both electronic boards. Reconfigure appliance configuration code in service mode. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
iD0
Dishwasher
Drive Motor, Inverter & Tachometer Sensor

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: Tachometer signal missing from variable speed wash motor iD0; inverter fails to verify motor rotation.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: Tachometer pickup coil open circuit (nominal 110–135 Ω on inverter motor), detached sensor magnet, or broken connector lead.

Measure tachometer resistance across motor pins 4 and 5 (nominal 110–135 Ω). Verify wiring continuity back to inverter board. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
iF0
Dishwasher
Water Inlet Valve, Aquastop & Flowmeter

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: Water fill timeout due to slow flow rate iF0; filling takes more than 4 minutes to satisfy pressure reference.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: Partially closed stopcock, clogged AquaStop mesh filter, lime-restricted water softener matrix, or low building water mains pressure.

Open supply valve fully. Unscrew inlet connection and clean strainer with brush. Check that filling flow rate reaches at least 3 L/min. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
iF1
Dishwasher
Water Level Pressure Switch & Air Dome

Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: Water level overfill warning detected by analog pressure sensor iF1; tub water level exceeds maximum safety mark.

On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry Dishwasher) models: AquaStop solenoid valve leaking water past its seat when unpowered, triac on main PCB shorted, or high detergent foam triggering false level.

Disconnect power: if water continues filling tub, replace defective AquaStop inlet valve. If water stops, inspect filling triac on PCB. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
SY EF
Refrigerator / Freezer
Refrigeration Compressor, Defrost Heater & PTC Relay

Zanussi Space+ / ZRB Series / LowFrost Combi Refrigerator: System evaporator fan circuit failure SY EF; electronic control module detects no rotation speed feedback from evaporator blower.

On Zanussi (Zanussi Space+ / ZRB Series / LowFrost Combi Refrigerator) models: Ice accumulation freezing the fan blades, defective 12V DC brushless motor windings, severed connector lead, or blown fan driver IC on main motherboard.

Remove freezer back panel. Spin fan blade to verify free rotation. Measure 12V DC across fan red and black wires, and verify pulsing feedback on yellow wire. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Diagnose
5Y EF
Refrigerator / Freezer
Refrigeration Compressor, Defrost Heater & PTC Relay

Zanussi Space+ / ZRB Series / LowFrost Combi Refrigerator: System evaporator fan circuit failure 5Y EF; alternative 7-segment display rendering of SY EF error code on user console.

On Zanussi (Zanussi Space+ / ZRB Series / LowFrost Combi Refrigerator) models: Ice accumulation freezing the fan blades, defective 12V DC brushless motor windings, severed connector lead, or blown fan driver IC on main motherboard.

Inspect evaporator fan behind freezer back wall. Remove frost with warm air. Measure 12V DC motor supply and verify tacho feedback signal. Hold Start/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.
