If you want to buy a washing machine at home, you must pay attention to doing maintenance work to avoid the failure of the washing machine, affecting the use of. Washing machine failure in use to find the cause and carry out repairs. So what washing machine repair methods? How to maintain the washing machine? Learn more about it.
What are the washing machine repair methods?
1 washing machine does not drain
(1) There may be debris in the drainage valve causing undrained drainage. At this time, first unscrew the valve cover of the drain valve to remove the debris;
(2) Check whether the adjusting rod nut on the drainage valve is loose, and the tractor cannot pull the drainage valve core to cause undrained. At this time, fix the nut so that it can open the drainage valve core;
(3) It may also be that the computer board is damaged and the computer board should be replaced;
(4) If the nut is not loose or the cable is not loose, the tractor may be damaged and the drain valve core cannot be opened. At this time, the tractor should be replaced;
2. In the waterless state, the pulsator is in normal operation in reverse
The water level switch contact is always open, if the contact piece is rusted, the elastic pressure of the contact piece fails, the contact cannot be disconnected, causing the water wheel to rotate normally and reversely.
3 washing machine water more than
(1) The problem may be caused by the water level switch. If it is used for a long time, the water level switch can stop water intake and cause water inflow. At this time, the water level switch should be replaced;
(2) If everything is not valid, try to replace the computer board, because all actions are controlled by the computer board;
(3) If the pressure pipe is worn out for a long time due to use, or if the pressure pipe leaks due to poor contact or disconnection of the water level switch and the outer cylinder nozzle, the water intake may also be caused. Because the computer board is under pressure, the water level switch does not operate. The misunderstanding is that there is more than water inflow at the water level. At this time, check whether the pressure tube is worn or not and whether the two joints are in poor contact or disengaged;
(4) The inlet valve spool is stuck and cannot be reset after the power is turned on, resulting in constant water intake. In this case, replace the inlet valve first.
(5) Due to a long time of usage, foreign matter is blocking the nozzle mouth and the pressure cannot be transmitted to the pressure switch. At this time, the big nut should be unscrewed and then the inner barrel should be removed to remove the foreign matter that blocked the gas nozzle.
How to maintain the washing machine?
In order to make the washing machine work well for a long time, it is necessary to carry out accurate lubrication and maintenance on time. The main areas that need lubrication are the bearings and gears. The bearings must be filled with oil-proof holes to prevent L-TSA22 from having good abrasion resistance and oxidation stability. Rust antioxidant grease, usually 2-3 years for refueling, such as the use of general mechanical oils need to be refueled once a year. Gears are applied with good adhesion No. 2 extreme pressure lithium-based grease, or oily, plus mass fraction For 1% zinc dialkyldithiophosphate, or MoS2, L-CKC No.100 medium EP anti-wear gear oil with a mass fraction of 3%. Lubricate the bearings and gears of the dryer. Oxidation of rust-proof and anti-wear good L-AN15 and L-AN68 lubricating oil. With a sealed rolling bearing, the bearing factory should be enclosed in the service life of more than 1000h, polyurea thickened refined oil lubricating oil, and added protection Rust antioxidant No. 2 grease.
Use the washing machine to pay attention to the maintenance and cleaning of the washing machine, which can also extend the service life of the washing machine. The above is about washing machine maintenance methods and how to maintain the washing machine related to the introduction, we must go to the formal market to buy washing machines, guarantee Washing machine quality.
