Troubleshooting
6.3.1
Dishwasher won't start
6.3.1.1 Door ajar or faulty door latch
The dishwasher won't start if the door isn't closed securely. 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 or door seal is misaligned, realign it. If the
door latch is broken, replace it.

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).
