Troubleshooting
6.3.1
Dishwasher won’t start
6.3.1.1 Door ajar or faulty / misaligned door latch
The dishwasher
won’t
start if the door isn’t closed securely or if
the door latch is misaligned. Push the door closed until the door
latch closes (i.e. until the latch clicks). If the dishwasher starts,
educate the customer on closing the door securely.
If the dishwasher won’t start when the door has been securely
closed, check the door latch with a magnet. Hold the magnet
over the Hall Effect sensor (located just left of the left screw) – if
the dishwasher starts, the sensor didn’t sense the door latch
magnet.
Occasionally a door can catch on the door seal and not close
securely. If the door, door latch or door seal is misaligned,
realign it. If the door latch is broken, replace it.
TIP
: If dishwashers won’t start, check:
•
Door latch, including alignment
•
Heat pump
•
Drain pump
6.3.1.2 Disabled or faulty pumps
If the dishwasher won’t start, check if the following parts are
disconnected or disabled. If they aren’t connected, reconnect
them. If faulty, replace them.
•
Heat pump
•
Drain pump
Dishwasher controls run safety checks – if drain pumps or heat
pumps are disconnected, dishwashers will
NOT
run.
6.3.2
Protection of heater if there’s no water
Two NTC’s protect the heater. Both NTC’s are checked by the
control – if they overheat, the control shuts down the dishwasher
(
E:08
error code). The dishwasher shuts down if only one NTC
returns a signal (
E:12
error code) or if they show different values
(
E:11
error code).
6.3.3
Drain pump terminal measurements
There is a single 3-pin connector,
connecting to the 3-pole BLDC
pump motor.
Resistances as follows:
1 – 2:
80.5
Ω (@ 68 ºF)
2 – 3:
