SENSOR FLOW

Set Appliance State:

Set Multimeter to Resistance

Isolate Mains Power to appliance as per TOPs P4
Disconnect connector J10 from the PCB
Ensure the flow sensor leads (red leads) are connected to the sensor and are
in good condition

Measurement:

Measure resistance across the connections at the disconnected plug (red leads).

Temperature Range (°C)	Resistance Range
0°C to 10°C	20.0kΩ - 32.0kΩ
10°C to 20°C	12.0kΩ - 20.0kΩ
20°C to 30°C	8.1kΩ - 12.0kΩ
30°C to 40°C	5.4kΩ - 8.1kΩ
40°C to 50°C	3.7kΩ - 5.4kΩ
50°C to 60°C	2.6kΩ - 3.7kΩ
60°C to 70°C	1.9kΩ - 2.6kΩ
70°C to 80°C	1.4kΩ - 1.9kΩ
80°C to 90°C	1.0kΩ - 1.4kΩ
90°C to 100°C	800Ω - 1.0kΩ
