Testing the Conductivity Contacts

Impedance Testing
It is possible to check the integrity of the conductivity contacts through diagnostics. Firstly enter
the Machine Status Screen as described in Section 7.1.1, and when in this mode, by touching
damp clothes or fingers across the conductivity contacts, the value adjacent to the word Touch will
increase. The minimum value is zero, this indicates an open circuit. The maximum value is 255.
No change in this value when touching the contacts, or conversely a high value when not touching
the contacts, would indicate a fault in this circuit.
Resistance Test
An alternative, but slightly less reliable method of testing the conductivity contacts, is to test the
circuit with a multimeter. When using this method the power to the dryer must be switched off.
Place one probe of the multimeter on each conductivity contact.
