Fault Code F24: Heater Relay Contact - Miele G 1 Series Technical Information

G 1xxx/G 2xxx
a Measuring time for 0.26 gallons (one liter)
b Test routine successful; water intake time is extended.
c Test routine unsuccessful; fault code F19 is registered.
a. During the first step, water intake solenoid Y2 is activated in order to let
another 0.52 gallons (2 liters) flow into the machine. The required time is
calculated on the basis of the time that the 0.26 gallons of water already
in the machine required for intake.
Note: The volume of water cannot cause the machine to overflow, even if
the flow meter is inaccurate.
Circulation pump M6 is now activated for 2 minutes in order to wet the
dishes in the dishwasher and to fill any spaces with water. Drain pump
M8 is then activated for one minute. This creates a measurement basis
for the actual test.
During the test, water inlet valve Y2 is activated until a defined number
of pulses corresponding to a water volume of approximately 0.37 gallons
(1.4 liters) is reached. Circulation pump M6 is then activated once more.
b. The program continues to run without interruption. The maximum water
intake time is extended to 4 minutes. This time value is saved by the
electronic for future water intake. For future water intakes, if the time
needed for 0.26 gallons to flow into the machine differs by 15 percent, a
new test routine flow will be started.
c. If heater pressure switch B1/13 is activated, the program is interrupted
immediately, the drain pump is operated, and fault F19 is registered.
Cause:
Flow meter defective.
Remedy:
Replace the water diverter. See Section 050-4.10.
Fault F19 will be displayed if the check to test the sluggish movement of the
flow meter (impeller counter) during the water intake is not successful.
