Leveling the appliance
Once the appliance is positioned, adjust the feet(screw them in o rout) to adjust
the height of the dishwasher, making it level to ensure the proper performance.
Charging hose connection
1.Connect the charging hose to a water faucet(with a unicouple).See
figure 4.
2.If the water pipe is new or has not been used for an extended period
of time, let the water run to make sure that the water is clear and free of
impurities, then connect it with the charging hose of the dishwasher.
3.The water pressure is 0.04-1.00Mpa.
Drain hose connection
Insert the drain hose into a drain pipe, or let it run into a sink, but the
free end of the hose must be at a height of less than or equal to 80cm
and must not be immersed in water.
Electrical connection
1. After making sure that the voltage and the frequency values for the
current in the home correspond to those on the rating plate, insert the
plug into an electrical socket which is earthed properly. See figure 6.
2. If the electrical socket to which the appliance must be connected is
not appropriate for the plug, replace the socket rather than using a
adaptor or the like as they could cause overheating and burns.

2.3 Notes
1. Accordi ng to the program requiring, when the dishwasher is heated to a certain
temperature, the circuit board will shut off the electric suppl y to the electrothermal
element.
2. Aqua-stop device: start up the drain pump and make the dishwasher stop its running.
3. The 90℃thermostat is closed under normal condition. When the dishwash er is heated to a certain
temperature, the thermostat will open to shut off the electric supply to the eletrothermal elements.
4. If the inlet valve has worked for 4 minutes, the pressure s witch has not acted, the dishwasher will
shut off all the loads and drain for 60 seconds, the al arm buzzer will ring for 30 seconds, at the same
time, the DRYING LIGHT coruscate then show on after drain ing.
5. If the drain pump ha s worked for 4 minutes, the pressure switch has not been reset, t he dishwasher
will shut off all the load s and drain for another 120 seconds after pressure swi tch reset, t he alarm buzzer
will ring for 30 seconds , at the same time, the RINSE LIGHT coruscate then show on afte r draining.
6. If the heating element have heated for 60 minutes, the thermocouple has not acted, the dishwasher
will shut off all the loads and drain for another 60 seconds af ter pressure switch reset, the alarm buzzer
will ring for 30 seconds, at the same time, the RINSE LIGHT and the DRYING LIGHT coruscate together
then show on after draining
7. If the micro switch for overflow protection has acted more than 2 seconds, the dishwasher will shut
off all the loads and drain for another 60 seconds after pressure switch reset, the alarm buzzer will ri ng
for 30 seconds, at the same time, the WASH LIGHT coruscate then show on after draini ng.
8. If the thermocouple have been checked for open circuit, the dishwash er will shut off al l the loads and
drain for another 60 seconds after pressure switch reset, the alarm buzzer will ring for 30 seconds, at the
same time, the WASH LIGHT and RINSE LIGHT coruscate together then show on after draining.
9 short . If the thermocouple have been checked for circuit, the dishwasher will shut off all the loads and
