Observation:
Inspect the fitment of the flow thermistor and the heating block thermistor.
1. Heating Block Thermistor
Thermistor should be fully inserted into the
heat exchanger pocket and clipped in place.
2. Flow thermistor
Note that newer versions no longer have this thermistor.
If it is not present skip this test.
Thermistor should be securely clipped to the flow pipe and
must be situated 25mm from the nut onto the heat exchanger
(in line with the fan mounting bracket).
Are the thermistor(s) correctly fitted?
