Dishwasher shocks: causes and troubleshooting

Many of us faced such a situation: taking out the dishes with wet hands or touching the metal parts of the dishwasher's body, there is a slight electric shock. Conventionally, the reasons for this behavior of the device can be divided into two groups. The first is related to internal damage in the unit's device, the second is caused by a wiring fault or improper connection to the network. Why is a dishwasher electrocuted from time to time, and what should I do? In our article we will try to give answers to these questions.

Damage to the machine itself

 This applies to technology that has served you for many years. Possible damage inside the machine:

• the integrity of the insulation on the wires is broken;
• engine malfunction;
• Damage to the heater or its activation relay.

Of all the reasons listed above, why a dishwasher periodically beats with electricity, the latter is the most common. Damage to the teng is due to Bad quality served water. You can open the case yourself and inspect the PETN for defects. If the damage is still found, it will be necessary to replace the part with a new one.

Remember! Dishwasher repair should only be done by a specialist.

Wiring fault

Such a problem is characteristic of machines recently commissioned. Dishwasher is a fairly powerful device, so you need to choose the right wiringso that it can withstand the load. Calculate the cable cross-section, given that the diameter of the copper wires must be at least 2 mm. Electricity will go from the junction box or shield. For better protection, purchase a circuit breaker. If your house has an old wiring, it is better to replace it with a new one, adding additional protective devices.

Incorrect electrical connection

One of the reasons leading to the fact that the car beats with current may be a violation of the rules of connecting the device to the mains.

Before mounting carefully read instruction manual dishwasher. Manufacturing companies establish their connection rules, since the technical characteristics of all devices are different. But there is a general recommendation for all models: the device should be connected to the power supply only through an euro-outlet with a reliable ground.

Remember! Operation of equipment without grounding is not allowed!

The principle of operation of the RCD

If there are no euro sockets, then it makes sense to install it, at least in the room where you plan to connect the dishwasher. From the idea of ​​replacing the factory Euro plug with the “Soviet” one should immediately be abandoned for reasons of electrical safety. In addition, you automatically lose your product warranty. In modern apartments, instead of grounding, they often produce zeroing: the wire is connected to a deaf neutral. In no case do not try to do it yourself - it does not take a lot of time for a specialist, and you can cost your life.

If it is not possible to change the wiring, use a residual current device that will stop the flow of electricity in the event of a leak.

RCD will not save you from electric shock, it will only reduce its strength. Before installation, carefully read in the instruction manual what type of this device is suitable for your model.

Other reasons

If the grounding and wiring are okay and the dishwasher is harsh, check the outlet itself. Contact may have oxidized. The location of the outlet itself is very important: it should be close to the device, at a distance 40-50 cm from the floor.

Important! Do not use extension cords when connecting a dishwasher!

Conclusion

As a rule, most minor faults that occur during the operation of a dishwasher can be repaired by yourself. But searching for problems related to electricity, should deal only with a specialist. Therefore, if you find that your dishwasher is electrocuted, unplug the unit and call a qualified electrician.
