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 the component are shown in the table below. PROCEDURE: Apply the probes of the tester to the points indicated and measure the resistance. After detaching the modular wiring connector fitted to the base of the appliance, measure the resistance to verify the efficiency of the components fitted to the dishwasher. N.B.:
If the resistance measured across contacts 1-8 and 3-8 of the motor is the same ( 28 ohms approx.), this means that the capacitor is short-circuited. The remaining components can be tested in the same way. The measurements can also be made directly on the component or on the modular connections of the control board. The test points and correct values are shown in the table below.
