Electronic Aquastop Hose

Mechanical Aquastop Hose

Mechanical Aquastop hose is connected to appliance just as universal water inlet hose.

1.Open the control panel and take out the PCB;

2.Unplug the CON3 and P4 wires , then use the multi-meter Ω shelf to measure resistance

between the blue wire (EV1) and white wire (IS). 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

fault(can’t fill the water) and this lock is non-resettable.
