1. Leaks the pressure on the pressure valve

电热水器常见故障排查方法

Reason 1:

The water inlet of the water inlet is too high, causing water to drip water.

Approach:

Add another pressure decompression valve on the waterway.

Reason 2:

The internal valve core is damaged or blocked by the internal valve, and the sealing is not strict and the sealing causes dripping.

Clean up a foreign body or replace the pressure reduction valve.

Reason 3:

The damage of the temperature controller has been heated, causing the dripping water.

Replace the temperature controller.

Remark:

During the heating process, the safety valve dripping water belongs to normal pressure.

2. Always heated and stop.

The temperature controller fails, causing the heating after the temperature is set.

: Replace the original temperature controller of the same specifications.

When the thermostat and the temperature controller fail, the water temperature continues to heat after the water temperature is over temperature.

Replace the original the same specification temperature controller and the temperature limiter, and it is strictly forbidden to be prohibited by the temperature controller and the temperature limiter.

When the above fails, when the safety valve cannot be disclosed, it is easy to occur in the inner biline rupture.

Replace the original same specifications.

Introduction to the temperature limiter:

电热水器常见故障排查方法

There are generally two types of thermostats: one is the temperature limiter of dual metal sheets, with low cost accuracy and commonly used at low -end machines; the other is high -temperature limit, fluid -inflation type, and commonly used in mid -to -high -end products.

The main role prevents the limited temperature. Once the limited temperature exceeds the limited temperature, the power channel will be cut off and the power supply is disconnected.

3. Discarding power plug jumping

The ground wire is charged to confirm the reliable grounding of the ground line, the ground line and the zero line voltage should be 0V.

Contact electrician processing ground line. (Electric thermal leakage action current 10mA, home leakage air switch action current 30mA. Therefore, the ground wire mild in some scenarios is only the water heater leakage of the border.)

The leakage power plug was damaged.

Replace the original leakage power plug.

Heating rod leakage, such as long -term use, poor water quality, not replacing magnesium holding in time, and the corrosion damage of the heating rod causes leakage.

Replace the heating rod of the same specifications, and it is recommended to replace the magnesium rod every 1 to 2 years.
