4.1Component Checking Procedure

Number Procedure

1Check Dropper Resistor:

This is checked at the power connector harness at the controller (P101)

Remove the harness from the controller, and using a multimeter check the resistance between pins 4 & 5

be careful not to spread the pins with the meter probes. The following resistances should apply:

NZ / AU / EU / UK

98 Ohms +/- 7 Ohms

US / CA

24 Ohms +/- 3 Ohms

If the dropper resistor is open circuit, then the heater plate will need to be replaced.

2

Check Fill Valve:

This is checked on the chassis harness (P205), between pins 10 & 11.

Remove the chassis harness from the controller, and using a multimeter check the resistance between pins 10 & 11 – be careful not to spread the pins with the meter probes.

The following resistance should apply:

65 Ohms (+/- 10 Ohms)

If resistance is OK, continue checking other components.

If shorted replace the fill valve, but continue to check the other components.
