Full automatic the water level discretion that the main effect of switch of washing machine water level is control washing machine.

Below normal circumstance, microcomputer is full automatic the water level switch of washing machine has 2 tab only. In did not get hydraulic when, the contact of two tab disconnects. After water level of program of catharsis of make choice of, choice, washing machine begins the work, advanced water, arrive when water level after certain height, the atmospheric pressure in filling pail air chamber reachs fair value, ' guide too tracheal transmit atmospheric pressure to sealing ring of balata of water level switch, overcome the bedspring of water level switch, power that seizes reed and urge action of balata sealing ring, make two tab contact puts through, give microcomputer a signal so, the specification already chose water level to place. Same make choice of takes off foreword of journey by boat, after washing machine catchment, water level fall back on is certain when height, because bedspring master piece is used, sealing ring of balata of water level switch recovers from an illness, and make two contact disconnect, give microcomputer signal of a movement, cross a paragraph of drain off water ' after time, microcomputer runs with respect to control electric machinery, begin dehydration. So, switch of overhaul water level can undertake according to the following method:

Above all, choose catharsis program, see water level after height of make choice of, whether does a powerful person that drink water stop to drink water, impeller has roll. If have, showing water level switch is normal, if do not have roll, still be in into water, guide with respect to need examination at this moment tracheal, have flat phenomenon to happen, if have, need to find out reason rehabilitate; If do not have, explain water level switch is abnormal, can check maintenance by the following method:

(1) opens control, examination water level opens the tab that shut and the outlet that control lead to have

Did not loosen, and make a contact undesirable, if loosen, need to insert plug and tab only prison can;

(2) dump, unplug next control lead outlet, measure water level switch with avometer resistor archives the resistance between two tab, will judge whether to guide, guide connecting is normal, if do not guide,connect, explain switch of this water level is abnormal, reexamination whether because be used for a long time or itself material is inscribed questioningly

And make damaged of sealing ring of balata of water level switch flat, if, need to change new water level switch;

(3) reexamination enters the water a switch control bedspring is normal, if bedspring power is too great,

Can make balata sealing ring moves suffocate suffocate, and cannot movement, right now, can adjust the attune on its

Section bolt, make its are in proper place can.
