5.10.3. Inspect Safety Hose

5.10.3.1. Electronic Aquastop Hose
1. Open the protecting box and take out the PCB;
2. With the door closed, unplug the CON3 and ACN wires , then use the multi-meter Ω shelf to measure resistance between the
blue wire (EV1) and blue wire (ACN). Open circuit and short circuit are both incorrect.
3. If the measured resistance is not correct, it means the valve coil is broken or the connector is loose. In this case, we should
check the connection first. If the problem hasn't been solved by re-connection, we should replace the safety hose.
5.10.3.2. Mechanical Aquastop Hose
Maybe moisture absorption of foaming material in mechanical device cause a self-lock fault(can't fill the water) and this lock is
non-resettable.

5.11. Diverter Valve

5.11.1. Work Principle

Diverter, also named alternating flow control valve, is used to control the flow of water between the upper and lower spray arms and
can also be used on some models to stop the flow of water to the upper spray arm on models equiped with a half load feature.

5.12. Error code

5.12.1. How to know which error code has occurred

To know which error code has occurred, refer to the previous table named Test Program Operation.
For example, if the error 7 has happened, the buzzer would alarm for 30 seconds and the Glass, 1 hour and Rapid indicators would
flash simultaneously. Other error alarms can be deduced from this.
