Maintenance of common faults of drinking fountains

Water dispenser leaks:
Internal: including internal silicone tube aging and cracking, aging of cold/hot tank welds, ice tank leakage, pipeline machine (solenoid valve) leakage, internal overflow caused by components such as water bottles.
Solution: Replace the parts.
Top: If water leaks from the top, it is usually caused by a broken water bottle component. The other is that the floating ball of the water purification bucket has a problem and cannot be sealed, but this situation generally does not occur.
Solution: Use it to check whether the water bottle is cracked.
Faucet: Most of the reasons are loose cap at the end of the faucet, cracking of the internal silicone sleeve, or internal impurities, scaling, etc.
Solution: Tighten the head cover and clean impurities. If none of the above works, the faucet can only be replaced.
resolvent:
The water dispenser leaks, not from the faucet, but from the inside of the fuselage, and the side of the fuselage feels very hot when touched by your hand. There are two reasons for this leakage. The water dispenser leaks from internal components of the fuselage, such as a broken silicone tube, a leak from a weld in a hot or cold tank, a leak from an electronic ice tank, a leak from a solenoid valve (piper), and an internal overflow caused by a broken water bottle, These usually require replacing damaged parts or using intact and qualified water bottles; The second is the leakage from the top, that is, the leakage from the smart seat, or it may be caused by the failure of the float ball and the inability to seal when using the water purification bucket.
If you are using bottled water, it may be caused by air leakage in the bucket. The leakage point is between the bucket opening and the bottle cap. All bottled water is repeatedly filled. During the filling process, the barrel mouth will have a certain degree of wear. It will affect the sealing degree between the bottle cap and the barrel opening. Therefore, it is recommended that you replace a bucket of water.
If it's not a bucket, you can only replace the Congmin seat. The air intake you mentioned is a mesh at the top of the smart seat. Air first enters the water distribution tank through the mesh, and then enters the bucket through the smart column. The water and air in the bucket exchange positions and then flows into the Huayu water dispenser.
"The small circular opening is designed to vent air. If the heating tank is not vented, it will explode. If the water is not boiled and there is no leakage, replace the heating thermostat. If the water leaks without boiling, the one-way valve at the bottom of the water filter is broken, and replace it.".
4. It is estimated that the float is broken, and a replacement float will be fine.
The water dispenser is not heated:
1、 Several situations where the water dispenser cannot be heated
(1) Water dispenser (indicator light not lit) does not heat
Possible causes: 1. The power supply is not connected; 2. The safety tube is burnt out; 3. The circuit board is broken.
Troubleshooting: 1. Check whether the heating switch is in the "ON" position. Whether the power socket has power; 2. Replace the safety tube; 3. Replace the circuit board.
(2) Water dispenser (indicator light on) does not heat
Possible causes: 1. The heating pipe is burnt out; 2. The thermostat is broken.
Solution: 1. Replace the heating pipe; 2. Replace the thermostat.
(3) Specific situation of the water dispenser failing to heat
The first situation: The water dispenser is not powered on, neither heated nor cooled. How can I repair it?
1. Check whether the power socket has power, and if not, connect it.
2. Check whether the contact between the power plug and the socket is reliable? If loose, insert firmly.
3. Check whether the internal and external power connections are disconnected? Is it detached from the plug-in? If any, connect it well.
2、 The indicator light of the water dispenser is on, but it is not heated. How to repair it?
First of all, check the fuse. The fuse should be located at the rear of the water dispenser. It is an insulated plastic headed, screwable protruding part that should not be difficult to find (slightly counterclockwise). You can take a closer look, (Some water dispensers require opening the rear cover to find them. If there are two symmetrical seats on the left and right sides, they are not safety sockets, but drainage pipes for cleaning. The safety pipes are separate, and the colors should be different.) Purchase two or three according to this model for standby.
Use a multimeter to measure the resistance of the heating pipe. If it is very low or 0, the heating tube should be broken.
"The connector, that is, the plug part, is in poor contact (or the zero line of this plug is open circuit, so that when you measure the socket, there should be power on both wires).".
The power cord oil of the water dispenser is used for a long time, and there may be internal disconnection. As long as one of the wires is disconnected, there will be no power input to the water dispenser.
The internal power input part of the water dispenser is disconnected due to corrosion and oxidation due to long-term humidity.
3、 The temperature control switch has tripped or the temperature controller has been damaged. Repair method.
Open the lid on the back of the water dispenser, and you should be able to see the cans that the water dispenser uses to heat water. Generally, there are two circular objects facing you with two strands of wire inserted respectively, which are temperature controllers. Generally, the lower one uses a repairable temperature controller, characterized by a small button. You can use a chopsticks to push the button to see if the water dispenser is working properly. If it is still the same, it must be that the temperature controller is broken. Only have they been replaced. The two wires on the temperature controller can be shorted to test whether they are good or not. If they are short-circuited and powered on, it can further prove that the temperature controller is damaged. Replace them. Be careful to check if the fuse is damaged. It is inside a black screwable item.
4、 The water dispenser does not heat, the power light is on, it cannot be heated, and the heating indicator does not light up until hot water is discharged.
It turned out that the safety inside the water dispenser jumped. Remove the rear panel of the water dispenser, and there is a black button to reset. The maintenance personnel explained that there might be no water in the water dispenser, and then they turned the heating button, but there was no water in it. A switch similar to the air switch tripped, which protected the water dispenser.
5、 Troubleshooting methods for common faults in drinking fountains
After removing the thermostat, perform a baking test with a 50W electric soldering iron. The on-off control of the thermostat is completely normal. At this time, it is suspected that the contact between the temperature controller and the water tank shell is not tight after installation, affecting the heat transfer. Fill a layer of thermal conductive silicone grease between the contact surface of the temperature controller and the water tank housing, tighten the temperature controller screws, fill the water dispenser with water, and then power on the water dispenser to test the machine. Troubleshoot the problem.
Experience: The reason why the yellow light does not turn on and the red light does not turn off in the water dispenser is due to the failure of temperature control. The root cause of temperature control failure is that the temperature controller is not tightly attached to the water tank shell, affecting the transmission of temperature and its perception of temperature. It is hereby reminded that when replacing the thermostat of a drinking water dispenser, it is necessary to apply a layer of thermal conductive silicone grease on the contact surface between the thermostat and the water tank housing to facilitate temperature transmission and avoid similar failures.
