Re: Hotpoint CDT80/85

F01 Motor triac in short circuit or
Relay of motor welded
closed.
– Verify if moisture has made a short circuit on connector J3;
– Verify if the motor connectors on board are ok. (Problems of
aggressive chemicals can generate a short circuit.)
– Change the board.
F02 Blocked motor. (Fan
blocked)
– Verify if the motor / fan is blocked;
– Verify the J3 connectors on the board;
– Replace motor;
– Replace fan;
– Replace main board.
F03 Front NTC open or short
circuit.
– Verify efficiency of the J12 connector on the board;
– Verify NTC on J12 connector, the value at Room temperature
of the NTC must be around 500 KΩ;
– If the measurement is out of range verify continuity of wiring
and verify directly on NTC without wiring;
– Replace NTC;
– Replace main board.
F04 No pump connection.,
feedback.
– Verify efficiency of contact J5;
– Verify wiring J5/Pump;
– Verify pump;
– Replace pump;
– Replace main board.
F05 No feedback from the pump. – Verify contact efficiency of J5 connector of the board;
– Verify if tension getting at the pump;
– Verify pump;
– Replace pump;
– Replace main board.
F06 Non used, active –
F07 Non used, active –
F08 Static heater Relay with NA/
NC contact welded closed
– Verify efficiency of contact J4;

Heater;
– Replace Heater;
– Replace main board.
F09 Error set up file. EEEPROM
is not programmed or not
functioning.
– If it is a production board with welded EEPROM, replace
board;
– If it is a board with removable EEPROM, check the correct
positioning of the EEPROM.
F10 Common of heater open,
one shot open.
– Verify efficiency of contact J4;
– Verify at room temperature (20°C) on the J4 connector if the
resistance between Pin 1 and 2 is 48 Ω;
– Verify continuity between wiring between J4 and Static (lower)
Heater;
– Replace Heater;
– Replace main board.
F11 No pump connection. – Verify efficiency of board contact J5;
– Verify wiring between J5 connector and pump.
– Replace pump;
– Replace board.
F12 No communication between
display board and control
board.
– Verify contact efficiency of board connector J9;
– Verify continuity between J9 and 5 leads connector of the
display board;
– Replace main board;
– Replace display board.
F13 Rear NTC open or short
circuit.
– Verify efficiency of J4 connector on main board;
– Verify at room temperature (20°C) is about 500KΩ;
– Verify continuity of wiring between J4 and NTC rear;
– If the measurement is out of range verify continuity of wiring
and verify directly on NTC without wiring;
– Replace NTC;
– Replace main board.
F14 Not used, active –
F15 Dynamic (PD) heater Relay
with NA/NC contact welded
closed.
– Verify efficiency of contact J4;
– Verify at room temperature (20°C) on the J4 connector if the
resistance between Pin 1 and 2 is 48 Ω;
– Verify continuity between wiring between J4 and Static Heater;
– Replace Heater;
– Replace main board.
F16 Not used, active –
F17 Master Relay welded closed – Replace main board
