Fault Codes and Possible Causes - LED Models
The following is a list of fault codes and possible solutions if a fault code is displayed.
FAULT Cause
F01 The motor is running when it
should be off.
F02 Open circuit between
module and motor Common.
F03 Front thermistor open or
short circuit.
F04 Pump working when should
be off.
F05 Pump is not working when it
should be on.
F06 Not used.
F07 Lower element failure
F08 Lower element is energised
when it should be off.
F09 Error Set Up File. Eeprom is
either not programmed or is
not functioning.
F10 Open circuit in the heater
Common wiring.
If testing for a Heater related fault, test on a Cotton High Heat setting or
F11 Open circuit pump circuit.
Service Manual UK
• Check if module connector J3 has shorted due to moisture.
• Replace module.
• Check security of module connector J3;
• Test motor Common (TOC);
• Check wiring between J3 and motor.
• Check security of module connector J12;
• Test from connector pins (approximately 500 Kohms);
• If open or short circuit, test thermistor and wiring between
thermistor and J12 to locate fault.
• Check security of module connector J5;
• Check connector for signs of shorting due to moisture;
• Replace module (F04 would normally be caused by a faulty
module).
• Check security of module connector J5;
• Check connector for signs of shorting due to moisture;

module).
• If the module is a production board, replace the module;
• If the module has an Eeprom socket, check the eeprom is
correctly inserted and programmed.
• Check module connector J4;
• Check wiring between module connector J4 and the heater;
• Test heater elements.
Note: - Frequent cycling stat operation can cause F10, check
filter and condenser for blockages.
a Timed setting with High Heat enabled.
• Test continuity of pump;
• Check connector J5;
• Check wiring between pump and module J5.
Note: - F11 is usually caused by a fault in the pump circuit not
the module.
