1. What to do if the wall-mounted pipeline machine does not produce hot water
If the wall-mounted pipeline machine does not produce hot water, the main control board may be defective, or the water outlet may be blocked by steam discharge caused by inconvenience. When the temperature of the machine rises to 99°C and no hot water is produced, first measure the working voltage at both ends of the heating tube. If it meets AC 220V, it is judged that the heating tube is defective; if there is no voltage, further measure whether the output of the temperature control and the main control power board has If there is no voltage, the motherboard is defective, and you need to contact the maintenance department for processing.
2. Common faults and solutions of pipeline machines
1. Water leakage
Caused by pipeline machines There are three reasons for water leakage: one is that the pipeline at the water inlet is not inserted in place or the surface of the pipeline at the interface is damaged. In this case, check and deal with it in time. The second is because the water inlet solenoid valve ruptures and leaks due to excessive pressure, and the water inlet solenoid valve needs to be replaced to solve it. The third type is that the internal pipeline of the pipeline machine is not in place. In this case, it is necessary to open the casing of the pipeline machine to carefully check the position of the water leakage of the machine.
2. No water
The water of the pipeline machine has cold water and hot water. If there is only cold water but no hot water, the heater is generally broken and needs to be Replacement, if there is no two kinds of water, first check whether there is water in the water purifier, if not, wait 20 minutes before restarting the switch of the pipeline machine. If there is water in the water purifier, you have to open the back cover of the pipeline machine, check the water inlet solenoid valve, the water inlet water pump and the limit switch of the water inlet water tank float one by one to see where it is damaged.
3. Hot water jet from the machine
When the hot water jet from the pipeline machine is encountered, it may be caused by the following four situations: One is that the water outlet is blocked by foreign objects, the second is that the assembly of the hot water pipe is distorted, and the third and fourth are that the working AC power supply is too high and the water inlet of the water tank is smaller than the water outlet, which will cause the machine to spray hot water. It is necessary to check the water outlet, hot water pipe assembly, working AC power supply and water tank one by one to see where the problem is.
Three, different typesPipeline machineFailures and solutions
1. Wall-mounted pipeline machine fault problem
(1) When the fault code displayed on the panel is E1, it is an over-temperature fault, which causes the device to lock and needs to be powered off and restarted.
(2) When the fault code displayed on the panel is E2, it means that the temperature sensor is faulty.
(3) When the fault code displayed on the panel is E3, and the water level cannot be reached within 60 seconds of power-on, the cold water probe fails.
(4) When the fault code displayed on the panel is E4, it means that the cold water probe is reversely installed or short-circuited.
(5) When the fault code displayed on the panel is E5, the hot water probe does not touch the alarm prompt for 60 minutes.
2. That is, the fault of the heating line machine
(1) When the panel displays the fault code as E2, it means that the hot water probe is bad or the main control board bad.
(2) When the panel displays the fault code as E3, the heating tube is defective.
(3) When the panel displays the fault code as F0, it may be that the water level of the water tank is not enough or the electronic float switch wire is falling off. If these two are excluded, it can be judged that the button is bad.
3. The problem of vertical pipeline machine failure
When the panel displays the fault code as E1 or E3, it means thermal protection, that is, the hot tube is dry-burning, Hot water probe take-off protection. When this happens, you only need to fill up with hot water and reset the probe automatically when the temperature drops.
