Electronic Aquastop Hose
Mechanical Aquastop Hose
Mechanical Aquastop hose is connected to appliance just as universal water inlet 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
shelf
to measure resistance between the blue wire (EV1) and blue wire (ACN). Open circuit and
short circuit are both incorrect.
3. I f 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.

Mechanical Aquastop Hose
Maybe moisture absorption of foaming material in mechanical device cause a self-lock
