7.2 Completing a Service

At the end of every service the following procedure should be followed to ensure the fault has been repaired, and the product is fully operational for the customer.

After replacing any component, run each hardware output individually for at least 10 seconds in diagnostic hardware output mode (HO) refer to p30 & 31 for the list of output devices.

If a long low tone is played at 1 second intervals, then the device being tested is faulty and should be replaced.

Running the outputs in the following order is recommended:

1.Fill Valve

2.Lid Actuators

3.Solenoids

4.Rinse aid pump

5.Detergent diverter

6.Water softener bypass valve (if fitted)

7.Water softener brine pump (if fitted)

8.Wash motor

•Do not run the wash pump with no water or lid not sealed on the tub. The wash pump will not operate with the tub in open position.

9.Drain pump

10.Heater plate

•Do not operate the heater plate without water present covering the heater plate. It is recommended to have at least 2.5 l (.6 gal) of water in the tub.

11.Run a fast test cycle.

Note:

When operating the rinse aid pump in diagnostics, rinse aid will be dispensed. If the testing is performed several times, rinse aid can build up inside the tub, and foaming may occur. It is recommended that any excess rinse aid should be removed from the tub before completing any service.
