Sometimes the user, including the washing machine, may find that it does not respond to keystrokes. So the first thing to check is whether the power cord plugs into the outlet and whether the electricity supply to the apartment turns off. If everything is fine with this, then there is some problem.
Why won't my Haier washing machine turn on? How to perform hardware diagnostics? Is it possible to repair the device yourself at home? Let's take a look at the nuances.
Understanding that the washer does not turn on is very simple. The control panel does not flash with lights, and pressing the keys on the tidy does not work - the machine continues to be silent. All this indicates that the machine cut off from the power supply. The reasons for this may be different:
Diagnosis is carried out from simple to more complex:
First of all, you need to flip the switch. Everything is in order with the machine, and a banal blackout causes its unwillingness to work. The next step is to check the electrical panel. Sometimes, with too much load on the network, the line does not withstand, and the residual current device is triggered. In this case, you must discard unnecessary consumers and restart the system.
Next, inspect the outlet from which the washing machine is powered. Usually, you can notice the problem with the naked eye:
If there are no external defects, check the outlet by plugging in any working electrical device (for example, a hair dryer). If the machine beeps, then the point is working. When there is also no contact, the reason is in the outlet.
You can change the output yourself or by inviting an electrician. For a washing machine, it is better to provide a separate outlet with high moisture protection.
After finishing external communications, you should pay attention to the automatic machine. First, take care of its network wire, and check it for defects. For example, a cord or plug can sometimes show signs of fire.
If the cord looks intact, ring it with a multimeter. After finding out that the network wire is faulty, replace the element. Repair, in this case, will be impossible - rewinding defects with electrical tape is unsafe.
Next, you need to check the noise filter. FPS protects the washing machine from power surges. From one sharp current surge, the device can burn out - because of this, the supply of electricity to the main nodes of the SMA will become impossible.
The noise filter checks with a multimeter. You need to do the following:
When the filter is in your hands, inspect it. It should not have traces of burn marks or melted contacts. If there are no external defects, arm yourself with a multimeter. Then, put the tester into buzzer mode and ring the FPS.
If the multimeter displays 0 or 1, the noise filter is defective. If the part is not repaired, you must buy a new device. Next, the FPS is put in its original place, and all previously disconnected wires are connected.
On older models of Haier washing machines, the power button sticking is often noted. And this may be the reason that the machine does not turn on. A faulty key prevents electricity supply to the control board, so the washer does not start.
Often sticky keys are noted in typewriters that are in the bathroom. Water gets under the button and provokes oxidation of the contacts. The current exchange is disturbed, and the washing machine stops turning on.
The serviceability of the network button checks as follows:
Next, the button needs to be tested with a multimeter. First, it is tested for breakdown, then for resistance. If the device detects a deviation from the standard values, you must buy and install a new key. Sometimes cleaning contacts can help, but it is recommended not to take risks but to immediately replace the element.
If everything is in order with the socket, power cord, noise filter and key, most likely, the main unit is malfunctioning. This problem is considered one of the most difficult and costly to repair. Semiconductor elements on the control board are sensitive to voltage surges in the mains and burn out during sudden changes. As a result, the chain is interrupted, and the machine does not turn on.
Sometimes the damaged area can still be determined with the naked eye - for this. You need to inspect the control board. Do the following:
What should you look for on a board? Any defects - black spots, oxidized areas, melted wiring. If everything is in order visually, you will have to contact the specialists at the service center for diagnostics.
You should only test and repair the control module with sufficient knowledge and experience. That can further damage the item. Only a competent mechanic can identify and solve the problem.
