Why does the water heater plug trip?


Water heaters are now installed in every family. The demand for water heaters in winter is also very large, but there are many problems in use. So today I want to talk about a problem that is easy to encounter, that is, the water heater plug is tripped. So what is the reason for the tripping of the water heater plug? How to solve it? Let's take a look at it together!


Reasons and solutions for water heater plug tripping

Reason 1: Is the leakage protector damaged?

If the water heater trips after being plugged in, the first possibility can be ruled out. The leakage protector is damaged. We all know that everything is normal before it is plugged in.

Reason 2: Circuit and electrical short-circuit phenomenon, resulting in excessive current

A water heater that trips after being plugged in may be due to a short circuit in the circuit, or a trip due to over-functioning.


Reason 3: Whether the power supply is grounded or repeatedly grounded

For example, if the wire is damaged, you need to pay more attention if it is the neutral wire, which is likely to cause leakage. 80% of such failures are caused by power line failures, because the power plug has its own leakage protection, as long as there is leakage, it will trip. There will also be automatic protection when the heating tube is broken, but the possibility of the heating tube breaking is small. The main reason for the failure of the power plug is the tripping caused by the excessive humidity of the plug and the ingress of water. As long as the moisture is dried, or the inside is dried with a hair dryer, it can be used normally.


Reason 4. The scale of the water heater heating pipe is too thick

If you are interested, clean and descale the replaced heating tube, and you can also find out where the electricity is leaking. If the scale is too thick, the pipe will burst, water will enter the quartz sand layer, and the water heater will leak and trip. Originally, the heating pipe and the water heater shell were insulated, but now you measure it with a multimeter, and the resistance must be very small. During maintenance, we often encounter this situation.


Reason 5. Whether it is in series with the neighboring house

Check whether the household trip is a leakage switch or an air switch. If it is a leakage switch, it must be caused by the leakage of the water heater. If it is an air switch, the trip is caused by a short circuit inside the water heater.

Reason 6. The components of the water heater are damaged

Whether the components of the water heater itself are damaged or the circuit of the water heater is damaged, it may cause the water heater to be plugged in and trip, which is also the function of the water heater thermostat to protect the water heater.
