Wanjiale gas water heater shows e3 what s going on, hello?

The appearance of E3 in Wanjiale gas water heater is caused by the action of the anti-dry burning device caused by the high temperature of the water tank, which is generally caused by the use of excessive water temperature, the mixing of cold and hot water, and dry boiling. When the water temperature in the water heater reaches the preset temperature of the overheat protection device, the overheat protection device will be disconnected, and the water heater will alarm and display E3.

Solution: Check whether the water heater is dry; Check if the magnet can be reset; Check whether the overheating protection is faulty, and reset it; Check whether the fuse is burned out, and it is best to replace the fuse; Check whether the Hall sensor is stuck, and clean up the debris; Check whether there is any stolen goods in the temperature measuring head, and clean the stolen goods of the temperature measuring head; Check if the water pressure is normal, and if the water pressure is too low, find the property to increase the water pressure.

It means that the temperature of the electric heater (rod) of the water heater is too high, and then the water heater stops working and the alarm goes off.

Causes this type of failure:

1. The circuit part is faulty.

2. The water heater is not cleaned for a long time. Too much fouling, heat conduction.

Undesirable. Just like wearing a cotton coat for the heater, the heat of the heater cannot be conducted, causing a fault alarm. Household water heater E3 error learning the second situation, solution:

1. Turn off the power.

2. Close the water supply valve, open the sewage valve of the water heater with a moving hand, and let the sewage in the water heater flow naturally, repeating several times until the outgoing water is clean. Install the sewage valve, open the water supply valve to fill the water heater, and turn on the power after that.

Electric water heater. In order to make the electric water heater at home last a few more years, it is best to use and maintain the electric water heater correctly. Maintenance method of electric water heater:

1. Pay attention to the first use.

Make sure it's secure: Make sure the installation is secure and leave enough space for the water heater to install on a solid wall. Make sure the water heater is powered by a separate power supply and has leakage protection.

Air discharge: Open the outlet valve and then water the water heater to ensure that the air of the water heater can be discharged smoothly, and then electrically heat after the water heater is full.

2. Check regularly, the water heater is easier to assemble in the heating pipe and other parts after a period of use. Regular maintenance of the heating tube can improve thermal efficiency.

It plays a role in saving electricity bills.

3. When not in use for a long time, turn off the power. When not in use for a long time, turn off the power and drain the water storage of the gallbladder; If the water output of the shower is reduced, it is necessary to clean up the blocked debris in time to ensure that the outlet is unobstructed, which is helpful to prolong the service life of the water heater.

The display of e3 indicates that the fan is faulty and stalled in the middle of the process. 1. It may be a problem with thermocouples. 2. It may be caused by insufficient water pressure or high or low water pressure.

3. It may be caused by too high temperature regulation. 4. It may be caused by the loosening of the terminal of the AC fan and the fact that the fan does not rotate. 5. It may be caused by damage to the starting capacitor of the fan.

6. It may be caused by damage to the computer board. 7. It may be that the solenoid valve is not opened correctly and the coil is burned out, and the gas water heater has an E3 failure. Suggested Treatment:

1. The damage of the thermocouple is generally due to poor contact or more carbon deposits, check whether the thermostat connection line is correctly plugged in or whether the thermostat is faulty, or check whether the hot fuse component is damaged due to dry burning, and replace the relevant components if necessary. 2. If the water pressure is unstable, you can turn off the gas water heater first, and then turn it back on after the water pressure is stable. 3. The temperature can be adjusted appropriately to solve the problem of E3 in the gas water heater.

4. The terminal of the fan can be inspected and reconnected if necessary. 5. You can check whether the computer board is damaged, and buy a new one to replace it if necessary. 6. When the starting capacitor of the fan is damaged, it is necessary to contact professionals for on-site maintenance.

7. You can check whether the gas balance is sufficient, and if necessary, go to the nearby gas service point to recharge to solve the problem of E3 in the gas water heater.

Wanhe gas water heater failure**E3 is the wind pressure protection**, the machine is to exhaust the smoke gas outdoors during normal operation, when the wind blows outside, the smoke pipe is too long, there are too many elbows, etc., it may cause the internal flue gas discharge of the machine is not smooth, it is possible to appear this**, if it is confirmed that there is no strong wind outside, the installation is also standardized and other external factors, it may be a problem with the wind pressure switch.

Maintenance method: 1. Reinsert or replace the thermal sensing pin and wiring.

2. Tighten the grounding wire so that it is in good contact.

3. Replace the water heater with a new battery.

4. Turn down the air pressure of the water heater to a normal level.

5. Adjust the position of the thermal sensing needle to keep it within the ignition range.

6. Replace the pulser if the pulser fails.

7. The solenoid valve cannot be repaired if it fails, and the solenoid valve needs to be replaced.

Wanhe water heater shows e3 for dry boiling. Workaround:

1. Check whether the water heater is dry boiling, and check whether the magnet can be reset;

2. Check whether the thermal protection is faulty, and reset it;

3. Check whether the fuse burns out, and it is best to replace the fuse;

4. Check whether the Hall sensor is stuck, and clean up the debris;

5. Check whether there is any stolen goods in the temperature measuring head, and clean the stolen goods in the temperature measuring head;

6. Check whether the water pressure is normal, if the water pressure is too small, you can find the property to increase the water pressure.

Wanjiale air energy water heater shows E3, which is usually caused by compressor high temperature protection or failure. Possible causes include: compressor overheating protection, which may be caused by an excessively hot external environment or poor air circulation; Compressor failures, such as electrical faults, capacitor failures, or damage to the compressor itself; The electronic macro control board is faulty.

It is recommended that you first check the environment around the air energy water heater to see if there are any objects that obstruct air circulation, and if so, please remove them. If the problem persists, it is best to contact Minqin's professional Vena team repairers to inspect and repair it.
