What should I do if Sakurai gas water heater 10F06 shows E2

The E2 fault of Yingxue gas water heater is mainly due to the failure of the exhaust system, it is recommended to check the flue and fan, and repair it after finding the cause of the failure.

Sakura Snow Gas Water Heater Fault Table and Maintenance Method:

1. E1: Ignition failure or flameout.

When the flame detection (feedback electrode) induced current is weak, it is judged that there is no fire in the burner, and the program is interrupted. At this time, you can check whether the feedback electrode is in the high temperature area of the flame, adjust the height of the feedback electrode, and check the connection line and plug of the feedback electrode;

Observe the combined electrode from the window for discharge. In this case, the discharge distance of the combined electrode can be checked, and the connection and pulse generator can be detected.

2. E2: abnormal wind pressure or fan failure.

When the flue is blocked or the flue resistance is too large, the wind pressure switch is activated and the program is interrupted. At this time, you can check whether the sampling pipe connected to the wind pressure switch is connected reliably, whether there is air leakage, whether there is any plugging error, etc.;

When the fan fails, the speed is too low or stalled, and the program is interrupted. At this time, you can check whether the connection line between the fan and the main control board is plugged in reliably, whether the fan is damaged, whether the fan is stuck, etc.

3. E3: action of anti-dry burning device.

When the thermostat action is disconnected, the program is interrupted. At this time, you can check whether the connection cable is connected reliably, whether the thermostat is faulty, and if the thermostat operates due to dry burning, it can be reset by itself.

When the thermal fuse assembly is disconnected, the program is interrupted. At this time, you can check whether the connection cable is reliably plugged and whether the hot fuse assembly is damaged due to dry burning.

4. E4: Failure of the temperature probe The temperature probe of the inlet and outlet water is open or short-circuited. At this time, you can check whether the connection cable is connected reliably and whether the temperature probe is damaged.

5. E5: Over-temperature fault When the outlet water temperature exceeds 93 for 10 consecutive seconds, the program is interrupted. At this time, you can check whether the water temperature probe is damaged, whether the combustion is abnormal, whether the water flow sensor is abnormal, etc.

6. E6: False fire fault If the time interval between opening and closing the water valve during operation is less than 2 seconds, the flame detection may determine that there is a remaining flame, and only the time interval between switching the water can be extended.

The fault of the Sakurayuki water heater automatically displayed**, the reason for the ** is shown on the manual

Display e0: Inlet water probe.

1. Poor contact of the wire plug, solution: replug the wire plug.

2. The temperature probe is damaged, and the solution is to replace the temperature probe assembly.

3. The main control board is faulty, and the solution: replace the main control board.

Sakuraxue water heater displays E0, which usually indicates that the temperature sensor is faulty or that there is a problem with the control board. Here are the possible causes and workarounds:

Faulty temperature sensor: A malfunctioning temperature sensor may cause the water heater to not read the water temperature properly, causing an E0 error**. At this time, it is recommended to contact the after-sales service center to replace the temperature sensor.

Control Board Failure: A damaged or other malfunction of the water heater control board can also cause an E0 error**. In this case, it is recommended to contact the after-sales service center for repair or replacement of the control board.

Loose or dirty circuit board: Check whether the connecting wire on the circuit board is loose, and if there is loose, the connecting wire should be re-fixed; If the circuit board is dirty, it can be cleaned with a beam roller professional cleaner.

Hello, dear, there are the following reasons for the occurrence of e0: 1. The smoke pipe is blocked. Workaround:

Clean and unclog the smoke pipes. 2. The wind pressure switch is faulty, the wind pressure switch is a safety device, its function is to check whether the flue is unobstructed, if it is open, it will work, if it is not open, it will stop working, if it fails regardless of whether it is unblocked, it will stop working, there will be smoke exhaust error. Workaround:

Repair and replace the air pressure switch. 3. Fan failure, the fan is responsible for transporting the oxygen from combustion to the wall-hung boiler and discharging the collapsed sock exhaust gas.

The display of e0** indicates a water flow detection failure.

Fault**: e0

Fault content: water flow detection failure; The inlet water pressure is less than.

Cause analysis and solution:

1. The tap water pressure is insufficient. Increase the cold water booster water pump (head more than 30m).

2. The head of the pump is insufficient. Replace the large head water pump (head more than 30m).

3. The pump is not started. Check the pump power supply, contactor; It needs to be properly connected.

4. The water inlet valve is not opened. Open the valve.

5. The external water inlet pipe or filter of the unit is blocked. Cleaning pipeline or filter screen 6, water pressure switch failure (measured higher. Replace the water pressure switch.

Find after-sales consultation. If you can make a free home repair during the retention period, even after the retention period, the appliance dealer can now provide the service.

Fault **e2

What it means: The ignition goes out halfway through, the water heater detects a flame, but then disappears again, and the machine shows e2.

The following tests should be performed gradually:

The air inlet is blocked by foreign objects such as raw material belt, resulting in a decrease in air intake.

The smoke pipe backwind baffle is jammed, resulting in poor smoke exhaust.

When the fan or fan starter capacitor is damaged, the wind speed does not rotate, causing the flame to go out.

The condenser drain hole of the condenser model is blocked, resulting in the accumulation of condensate in the condenser, and the flue gas cannot be discharged, resulting in E2 failure.

The 4th or 5th nozzle on the right side of the distributor is blocked, causing the flame to go out and report an E2 fault when the fire is switched.

Unplug the smoke pipe and check the smoke exhaust port of the machine to check whether there is a large amount of carbon deposit, the liquefied gas model is easy to accumulate carbon due to poor combustion, and it needs to be dismantled and cleaned, and the pressure of the liquefied gas source is checked.

If it has been used for a long time, there is also a possibility that it is due to the scale blocking the hot water pipeline, causing false alarms.

If the hot water flow is obviously small, it should be a problem of scale blockage, buy a set of gas water heater online without removing the scale, and inject descaling agent to solve it.

1. The air inlet is reduced due to the blockage of foreign bodies; 2. The smoke pipe wind shield is stuck, resulting in unsmooth smoke exhaust; 3. After the fan or fan starting capacitor is damaged, the wind speed does not rotate, resulting in the flame extinguishing;

4. The drain hole of the condenser of the condensing model is blocked, resulting in the accumulation of condensate in the condenser, and the flue gas cannot be discharged; 5. The 4th or 5th nozzle on the right side of the distributor is blocked, resulting in the flame extinguishing and E2 fault when the fire is converted; 6. Open the smoke pipe and check the smoke exhaust port of the machine to check whether there is a large amount of carbon deposit, the liquefied gas model is easy to accumulate carbon due to poor combustion, and it needs to be disassembled and cleaned, and the pressure of the liquefied gas source is checked;

The solution to the E2 fault of the Sakuraxue water heater is as follows:

1. First of all, check whether the fan has been turned on, if the fan is not turned on, it may be that the fan or power controller is faulty.

2. If the flue of the water heater is blocked, there will also be an E2 failure, and the problem can be solved by cleaning the blockage in the flue.

3. During use, there is air in the smoke exhaust pipe, which causes the water heater to fail to exhaust, resulting in E2 failure, and it is necessary to install a hood at the smoke exhaust port to avoid this situation.

Water heater note precautions:

1. When using the electric water heater, when the water valve is opened and there is no water out, the power supply should be disconnected immediately to prevent the electric water heater from being damaged due to failure when it works without flowing water.

2. When using an electric water heater, avoid damage to the electric water heater due to the high temperature of the outlet due to the water inlet being too small.

3. When using the storage electric water heater, Xiangyin must be filled with cold water before heating with electricity, open the hot water valve and have water flowing out, then the water storage is suitable and can be energized, and the valve is strictly prevented from being installed at the water inlet and outlet at the same time.

4. When using an electric water heater in an area with a freezing period, it is necessary to ensure that the water in the water heater has a certain temperature and will not freeze, otherwise the electric water heater will be damaged.

5. In order to prevent scalding, you can open the cold water valve first, then open the hot water valve, close the hot water valve first, and then close the cold water valve.

E1 indicates that there is some kind of failure in the machine, and in general, E1 refers to the unsuccessful ignition and combustion of the machine, and there are many reasons. Because the fault of each brand and various models is different, the manufacturer settings are different.

If you look at the manual or the case of the machine, it should be printed with the first explanation and solution when the machine you are using fails. The best thing you can solve by yourself is that if you can't, you can only ask the after-sales service personnel of the factory to solve it.

E1 means that the initial ignition does not fail, which means that it is not good to ignite.

There are many reasons why gas water heaters are not good for ignition, and any component damage of water, gas, and electricity will cause the water heater to fail to ignite.

Let's find a maintenance master.

E1 fault** indicates a lack of water in the tank. Check the water supply system. Is there a blockage on my road?

E1 ignition is unsuccessful, see if your gas is turned on, see if the water pressure is enough?

If it's under warranty, you can ask for a new one.
