working; take the sensors
out* and
measure the resistance
with a multimeter at room
temperature (20 - 25°C);
the sensor is working
properly if the resistance is
between 12 and 15 kOhm.
[E][2]
Return
temperature is
higher than the
flow
temperature.
Insufficient water. Check the water level and
check for leaks.
No through flow. Check that the pump is
working; turn the spindle
