Why won't the dishwasher turn on and what should I do?

Household appliances sometimes become inoperative, and most of the faults can be corrected on their own. For example, if the dishwasher turns off and does not turn on, or turns on and hums, but refuses to function - it stands and blinks the lights - then the reasons for this inaction should be established. They can be so obvious that it makes no sense to wait for the master and pay for his work. In this regard, the first question that arises for the user when the dishwasher suddenly stops functioning is what to do?

When the dishwasher does not turn on, do not rush to panic and call service. Let's try to figure out what the essence of the matter is. Maybe it's not so scary.

Here is a list of the main reasons why PMM does not turn on:

1. the power cord is broken;
2. defective power outlet;
3. the mains voltage filter is damaged;
4. the lock on the door is broken (a working lock clicks when it is closed);
5. the "start" button is faulty;
6. burned out capacitor;
7. the software control module is out of order;
8. burned out engine or relay.

The first thing to diagnose is the presence of electrical power. After making sure that the electrical outlet is in good working order, you need to exclude cable defects.

1. Disconnect the device from the mains, visually inspect the cord... It should not be melted, transferred, have insulation defects or breaks.
2. Test some sections of the cable with an ammeter. Contacts can be broken in the body of the cord, even when it is perfect on the outside.
3. Estimate, what is the condition of the plug.

To check the capacitor, you need to disassemble the machine. We recommend placing a cloth on the floor first, as residual water may leak out of the machine.

Condensers are located on a circular pump, under a pallet. The dishwasher is disassembled in the following order:

1. remove the front panel under the car door;
2. dismantle the side mounts from the pallet;
3. open the door, unscrew the dirt filter and dismantle the impeller;
4. we close the door, turn the machine over and remove the pallet;
5. we find a capacitor on a circular pump;
6. We check the resistance with an ammeter.

If a capacitor is found to be faulty, it is necessary to purchase an absolutely identical one and change it.

This device takes over all stress and interference. If it breaks down, it is replaced.

When there is no characteristic click when the door is closed, the lock is most likely faulty. The door does not close tightly, resulting in fluid leakage. The malfunction, as a rule, is accompanied by an error code with a corresponding indication in the form of an icon, which does not happen every time. To replace the lock, the dishwasher is disconnected from the network, the decorative panel and control panel are dismantled, the lock is unscrewed and a new one is installed.

Sometimes, when you press the power key, it is obvious that it does not work or it sinks unusually. In all likelihood, the point is, in fact, in her. Or the pressing is done as usual, but there is no response from the machine - with a high probability one can suspect the same key. It fails if handled carelessly. However, damage to the contacts is allowed, for example, as a result of oxidation or burnout.

A defective control board is a serious failure.... In this regard, the equipment either does not turn on outright, or functions malfunctioning. The unit is capable of failing after the flow of water. For example, during transportation, you did not remove the remaining liquid from the machine, and it ended up on the board. Voltage fluctuations affect the electronics in the same way. You can only inspect the element yourself, however, only a specialist can talk about repair or replacement.

How to get to the control module:

• open the door of the working chamber;
• unscrew all the bolts along the contour;
• cover the door and dismantle the decorative panel;
• disconnect the wiring from the unit, first remove all connectors.

If burnt parts are visible on the visible part of the board or wires, therefore, repair is required urgently. Take the item to a service point for inspection.

In case of such malfunctions, water is poured, after setting the required mode, the dishwasher beeps, the sink does not turn on. The unit is disassembled, the relay and the engine are checked with an ampere-voltmeter.

In order to avoid complications with the functioning of dishwashers, it is required to monitor their work and carry out periodic maintenance of the unit. This will take much less of your time than looking for the cause of the failure and its further elimination.
