Hello everyone, Lin Fei to answer the above questions, water heater fault maintenance which is good, water heater fault maintenance many people do not know, now let's take a look!

Water heaters are very common and indispensable in our lives. They have very good heating performance and now have many characteristics of water heaters. For example, the most popular water heater is solar water heater, its heating performance is very good, and it is also a kind of green water heater. But there will be all kinds of problems when the water heater is used for a long time. Once there is a problem, it should be fixed. No matter what kind of water heater is heating, its performance is very good, but we must maintain the water heater when using it, otherwise it is easy to break down.

How much does it cost to repair the water heater?

In fact, the current home appliance maintenance market is very chaotic, because the major enterprises in after-sales maintenance, maintenance prices are not the same. At the same time, the home appliance maintenance market is mixed, and many small vendors without professional skills also want to get a piece of the pie, resulting in random charges for home appliance maintenance out of control. Most of the time, it is for this reason that many people are really tired of repairing water heaters.

When the water heater is repaired, it should also be priced according to the price of the parts that need to be replaced during the maintenance process. Some water heater parts are usually between ten and dozens of dollars, and some parts are between one hundred and two hundred dollars. It may be that the maintenance steps of the water heater are very simple, but if the parts that need to be replaced are very expensive, the final maintenance cost will be higher. If the maintenance steps are complicated, but the replacement parts are cheaper, so the final maintenance cost is usually not very high, mainly depends on the failure of the water heater. (the price comes from the network, for reference only)

Common faults and maintenance methods of water heater

1. Failure and leakage

Maintenance method:

1. Water valve plate hole leakage: the leakage is generally caused by improper assembly or wear of the rubber ring (see figure 9). When replacing, special riveting tools should be used to ensure flatness, and check whether the push rod can move flexibly in the axial direction.

two。 Leakage of water valve nut: check whether the nut is cracked and whether the rubber ring on the screw is worn. If worn, a new rubber ring can be replaced.

3. Water valve body leakage: check whether the inlet joint is tight, whether the rubber ring is damaged, whether the valve body has sand hole and other leakage, whether the water valve disc is damaged, whether the tympanic membrane assembly is correct.

4. Heat exchanger leakage: check whether the heat exchanger and valve body rubber rings are sealed. In case the heat exchanger leaks. When conditions permit, oxygen welding can be used to repair, but burnt out heat exchangers generally can not be repaired and can only be updated.

two。 Failure and air leakage

Maintenance method:

1. Big wind valve leakage: the main reason is that the air valve body is damaged, the air valve body and the air valve cone do not match well, or scratches or sundries cause air leakage, which needs to be replaced. As the matching accuracy of the valve body and the valve cone is high, it is generally necessary to replace the valve body and the valve cone at the same time according to the matching situation. Air leakage caused by high atmospheric pressure is the most common phenomenon, indicating that the parts of the switch panel are burnt out. This kind of air leakage is not a quality problem of the water heater, so the user should install the pressure reducing valve.

two。 Small gas valve gas: this kind of air leakage is only reflected in the ignition, that is, the ignition tube continues to catch fire after it is released. If the assembly is improper or damaged, the rubber ring on the small valve shaft should be reassembled or replaced. There are sundries on the sealing point. Clean it up and apply some grease.

The emergence of water heaters has greatly changed our way of life. We can take a hot bath in winter or summer, which is the convenience of the water heater. And the principle of the water heater is also very simple, that is, the medium is used to heat hot water. The common heating energy sources are natural gas, solar energy, magnetic energy, air energy and so on. However, no matter which kind of water heater is used improperly, there will be problems. Then, Bian Xiao will tell you about the maintenance of the water heater.
