Thermistor Resistance Readings:
F10
Open circuit in the heater
Common wiring.
•
Check the wiring between the cycling stat and the module;
•
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. The module checks and
waits 3 times before displaying F10.
F11
Open circuit pump circuit.
•
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.
Auto cycle being used fault displays within 1
minute Time and Wool cycles being used fault displays
at the end of the cycle.
F12
No communication
between display module
and control module.
•
Check connector J9 on module;
•
Check wiring between module connector J9 and display;
•
Check display connector;
•
Replace module, display or wiring as required.
F13
Rear thermistor open or
short circuit.
•
Check security of module connector J4;
•
Test from J4 connector pins 1 and 2 (approximately 500
Kohms);
•
If open circuit, test thermistor and wiring between thermistor
and J4 to locate fault.
F14
Upper element failure
•
Check security of module connector J4;
•
Test between pins 4 and 5 on J4 (approximately 48 ohms);
•
If open circuit, test upper element and the wiring between J4
and the heater.
F15
Upper element is on when
it should be off.
•
Check security of module connector J4;
•
Check connector for signs of shorting due to moisture;
•
Check heater elements and wiring;
•
Replace module (F15 would normally be caused by a faulty
module).
F16
Not used.
F17
Master Relay contacts
welded closed.
•
Reverse polarity
• Replace module
