The water heater had hot water at the beginning, why did it turn cold later?

Because the hot water in the tank of the storage electric water heater relies on the tap water cold water to enter the tank and push the hot water out of the top of the tank, the water in the tank is always full, the bottom of the tank enters the cold water, and the top of the tank comes out of the hot water, and the hot water and cold water will cool down after mixing, so the water in the tank will slowly become cooler.

If the hot water was originally sufficient, and then the amount of hot water becomes less and less, it proves that there is too much limescale in the water heater. The space in the water heater is fixed, and if there is more scale, there will be less water, which is naturally not enough. At this time, you need to call the brand after-sales service and let the maintenance personnel come to clean up, which is about 300 yuan.

Do not disassemble the water heater by yourself, so as not to cause water leakage or electricity leakage in the water heater.

It should be that after the water heater runs out, there is no hot water in the tank, so it will become cold water, I hope mine is helpful to you, I wish you a happy life goodbye.

The water heater suddenly turns cold during bathing because the fire drain stops working. The reasons that cause the fire discharge to stop working and indirectly make the water heater have no hot water output are as follows:

If it's a tankless water heater, there may be a problem.

If it is a fast-heating water heater, it may be that the supplementary hot water in the small tank is running out and needs to be heated again.

Probably because the hot water ran out, the cold water went in automatically, but it was not heated.

There are several reasons why water heaters change from hot to cold:

1. The water heater has an over-temperature protection device, in the process of bathing, the water temperature is too high for too long to reach the temperature control controller, and the power supply of the solenoid valve is cut off.

Solution: Appropriately shorten the time, can be used intermittently or pause and turn on instantly, adjust the water temperature switch, do not hit too high.

2. The circuit cannot work normally due to the failure of the thermostat itself.

Solution: Replace the thermostat directly if the thermostat is damaged.

3. The solenoid valve is suddenly damaged during use, resulting in no air supply.

Solution: Replace the solenoid valve directly if the solenoid valve is damaged, these important parts cannot be used.

4. The fire row is seriously blocked.

Solution: When the discharge is seriously blocked, it must stop working, cut off gas and electricity, and permeate the thin steel wire.

5. The battery power is low enough to supply the solenoid valve and push it to work, resulting in no air supply.

Solution: The battery must be kept sufficient, otherwise it will not be able to push the solenoid valve to work, and the new battery will be replaced directly.

6. The power supply circuit is faulty, including the poor contact of the terminals of various electronic accessories.

Solution: If there is a problem with the circuit, it should be sent for repair to avoid potential safety hazards. If the wiring of electronic accessories or the contact of the terminal is poor, it can be rewired and replaced with a new terminal.

7. There is no gas output from the air source.

Solution: Replace the air supply.

8. There is no gas supply due to the failure of the gas fire control valve.

Solution: Replaceable gas control valves.

9. The water heater with leakage protection device jumps away due to leakage protection, or the leakage protector itself is damaged and causes passivity.

Solution: The leakage protector is to protect the risk of electric shock during the bathing process, if it goes wrong resolutely replaced, life safety is more important than everything!

Because of the power outage, the water heater could no longer boil hot water, so it became cold water. Or the water heater is broken, and the water can't be boiled.

1. The water pressure is sufficient, but the water pressure is unstable. Because of the increase of water pressure, the cold water outlet of the mixing valve is directly connected to the water inlet pipe, when the cold water increases immediately, and the water outlet pipe of the water heater plays a buffering role due to the water in the inner tank, and the hot water outlet is not affected much instantly, resulting in the water outlet becoming cold after mixing.

2. The cold water valve of the water heater is not opened to the maximum. Because the tap water is not turned on to the maximum, the water heater will be turned off due to insufficient flow and high temperature when the water temperature is adjusted at the outlet of the chain water.

3. The pressure reducing valve is abnormal.

4. The inlet of the water heater is blocked.

The electric water heater shows that there is hot water, but after a while it turns into cold water, which may be caused by unstable water pressure.

Summary. The unstable water pressure of the water heater or the adjustment of the temperature in the middle will cause the water heater to produce cold water for a while and hot water for a while; Because once the water pressure of the water heater decreases, the outlet of the cold water will decrease, and the outlet of the hot water will change due to the effect of water pressure.

During the use of the water heater, adjusting the controller of the water heater at will will also cause the water temperature to fluctuate from cold to hot.

The electric water heater shows that there is hot water but it turns into cold water after a while, what is going on?

Unstable water pressure of the water heater or adjusting the temperature in the middle of the water heater will cause the water heater to produce cold water for a while, and orange to transport hot water for a while; Because once the water pressure of the water heater becomes smaller, the outlet of the cold water will be reduced, and the outlet of the hot water will be affected by the action of the water pressure and call for a change. During the use of the water heater, adjusting the controller and bridge of the water heater at will will also cause the water temperature to fluctuate and heat up.

It's that the outlet pipe in the water heater is broken, and it's good to find an after-sales service to replace a stainless steel one. The original is plastic and other materials, which will age and break after a long time, that is, the hot water comes out of the lower part of the water heater, and it will be replaced by the cold and nai sun water top lifting chain for a while, and the upper part is still hot water, but it can't come out. Do you understand?

Replace a stainless steel one.

Hello, if mine is helpful to you, please give it a thumbs up.

Have a great day.

The hot water of the water heater will become cold water after a while, which may be due to the design of the water heater or due to improper use of the water heater. First of all, it may be due to the design of the water heater, the design of the water heater may affect the temperature of the hot water, if the design of the water heater is not reasonable, it will cause the temperature of the hot water to be unstable, so that the hot water will cool down quickly. Secondly, it may be caused by improper use of the water heater, if the temperature of the water heater is not set properly, or if the water heater is used too frequently, it will cause the hot water to cool down quickly.

In addition, the aging of the water heater will also cause the hot water to become shorter and cooler quickly, and if the water heater is used for too long, the heating element of the water heater will be damaged, resulting in the hot water becoming cool quickly. Therefore, if the hot water of the water heater becomes cold after a while, it may be due to the design of the water heater or due to the improper use of the water heater, it is recommended that you check whether the design of the water heater is reasonable, check whether the temperature setting of the water heater is correct, check whether the frequency of use of the water heater is too high, and check whether the water heater is aging, so as to solve the problem of hot water cooling in time.

The reasons why the hot water of the water heater will become cold water for a while are as follows:

1. The unstable water pressure of the water heater or adjusting the temperature in the middle of use will cause the water heater to produce cold water for a while and hot water for a while. If the water pressure of the water heater decreases, the outlet of the cold water will also decrease, and the outlet of the hot water will change due to the action of the water pressure.

2. If we adjust the controller of the water heater at will during use, it will also cause the water temperature to be hot and cold.

Precautions for using water heaters:

1. When using the water storage filial piety electric water heater, the water heater should be filled with water first, and then connected to the power supply, and then used after preheating. If you experience a drop in water pressure or a water outage, it is best to turn off the power at this time.

2. When the water heater is on the water, the water outlet should be opened at the same time, and the air in the inner tank of the water heater such as the rock sedan should be drained clean, and then check whether the water is full.

3. On the temperature regulator of the electric water heater, there will generally be a logo and scale of the water temperature, which is used to indicate the adjustment position of the low, medium and high water temperature. As long as we point the knob of temperature adjustment to a certain scale, the water temperature of the water heater will be kept in the current temperature range.

4. The correct way to use the water heater is to adjust the controller in advance before using the water heater to avoid encountering hot and cold water temperature during the bath.
