hotpoint ctd40g flashing lights

[zaffygsi]

hi i have a hotpoint ctd40g condenser dryer and have no heat it has a on/off light flashing as well as the high heat and time delay lights flashing i would be most gratefull if anyone has any info on what this could be many thanks.

A fault is indicated by the On/Off Led flashing rapidly, plus a combination of Led's are used to display error codes.

The top four vertical Led's together with the far right (Post Care) horizontal Led are the ones used for this.

Each Led has a set value.

The top, right (Post Care) Led =16

The 1st from top vertical Led =8
The 2nd from top vertical Led =4
The 3rd from top vertical led = 2
the 4th from top vertical led = 1

To obtain the error code, simply add the values of these Led's and compare them with the table given for the CTD80/85.

For example:
Vertical LED two =4, LED four = 1. 4+1 = 5, fault code is F05, no feedback from pump.

Some faults will allow the motor to continue for 20 Mins without heater to allow cool down. 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 Lower element failure
Check security of module connector J4;
Test between pins 4 and 3 on J4 (approximately 48 Ohms);
If open circuit, test lower element and wiring between J4 and
the heater.
70802.0000, from this serial the one shot thermostat is wired into module if this operates the unit will appear dead
F08 Static heater Relay with NA/
NC contact welded closed
- Verify efficiency of contact J4;
- Verify at room temperature 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.
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
