TROUBLESHOOTING
CHECKING THE EFFICIENCY OF THE COMPONENTS
In order to facilitate checking of the efficiency of the component to be tested, a special CONTROL
PROCEDURE has been created. The contacts to which the tester should be applied and the correct
resistance for each component are shown in the table below.
After detaching the modular wiring connector fitted to the bottom of the appliance, measure the resistance
to verify the efficiency of the components fitted to the dishwasher.
TRADITIONAL DISHWASHERS (ELECTROMECHANICAL TIMER)
PROCEDURE: Apply the probes of the tester to the points indicated and measure the resistance.

N.B. If the resistance measured across contacts 1 - 8 and 3 - 8 is the same
(28 Ω

ma = brown ne = black ro = pink vi = purple
The remaining components can be tested in the same way or directly on the components themselves.
