Primus RF6 Programming Manual page 112

DIAGNOSE:
1. Check if the heating contactor is activated
2. Check if the heating elements are heating
3. Check if the temperature sensor is
functioning
4. Check the output relay that powers the
heating contactor
5. Check the output relay that powers the
heating contactor
FAILURE 14: HEATING TIME FAILURE
When after x minutes the target temperature is not reached (for a machine set as wait for heat):
Message 14 will be displayed.
x = the programmed Max heating time in the Intialization Menu.
DIAGNOSE:
1. Check if the programmed Max Heating time
in the Initialisation menu is acceptable.
2. Check if the heating resistors are heating
3. Check the water temperature
4. Check if the temperature sensor is
functioning
FAILURE 15: TOO HOT
When the water temperature is 15°C above the target temperature : message 15 will be displayed.
For evaluation of the problem, you can follow the water temperature of the bath on the display of the washing
machine by pressing the Service Button on the keypad.
DIAGNOSE:
1. Check if correct water inlet valves have
been programmed.
If only hot water inlet valves have been
programmed, and if the hot water supply
has a temperature value above
the programmed wash sequence value then
the temperature of the wash bath will be too
high.
2. Check if the correct water inlet valves are
Functional.
If the cold water inlet valves are not
functional or if the main cold water supply is
not available and only hot water inlet valves
are open, and if the hot water supply has a
temperature value above the programmed
110
If the heating contactor is not activated: repair the
wiring or replace the contactor
If the heating elements are not heating:
Repair the wiring or replace the defective heater
elements
If the temperature sensor is defective: replace the
temperature sensor
If the relay is broken, replace the electronic board
If the relay is not broken, but doesn't receive a signal
from the electronic board, replace the electronic board
If the machine has a small heating capacity, increase
the value of the Max heating time.
The default is 60'. (For machines with big heating
capacity)
If the heating resistors are not heating:
Repair the wiring or replace the defective heater
elements
If the hot water supply temperature is to low: increase
the temperature of the hot water
If the temperature sensor is defective : replace the
temperature sensor
Choose the correct water inlet valves for the wash
sequence when you create or adjust the parameters of
the wash program.
Don't program only hot water inlet valves but also cold
ones !
