With the rapid rise of electric water heaters,Water heater transformerThere will also be various problems. Today I will talk about the maintenance of some problems.
(One)The water heater works, but the temperature does not reach the set value.
(1)We use a multimeter to measureWater heater transformerWhether the power supply voltage is normal. If there is in the power box220VVoltage, when the water heater works when the voltage drops too much, we have to consider whether the line diameter of the power supply to the water heater is too small.
The solution is generally to replace the wire.
(2)Use a multimeter to measure,Water heater transformerThere is no abnormality in the power supply voltage. This should be damage to the heating part or temperature control part of the water heater.
The solution can be to call the manufacturer for after-sales maintenance, or to buy the same type of heating body assembly or temperature control motherboard replacement.
(II) Water heater transformerFrequent trips
(1)Generally, it is possible that the empty opening setting is small.
The solution is to replace the empty opening that matches the water heater.
(2)Whether the wire diameter is small. Small wire diameter produces overheating.
Solution Replace the wire.
(Three)The water heater crashed.
(1)It may be caused by improper operation of the user.
Solution Use the water heater according to the operating instructions.
(2)Failure of the water heater itself(Display board, computer chip damage)
Solution Replace the chip or display board of the same model.
(Four)The key switch of the water heater is not good, and the touch key is not sensitive.
(1)The key switch is damaged, or there is virtual welding in the line.
Solution Replace the switch or check whether there is a virtual solder joint in the switch connection and reconnect it.
(2)Check whether the touch key circuit has open soldering place, if not, only replace the display panel.
(Five) Water heater transformerDoes not work after power on
(1)Caused by improper user operation.
Solution Follow the instructions in the operating manual.
(2)The transformer connected to the main board is damaged.
Solution Replace the same type of transformer.
(3)The ground wire is not reliably connected.
Solution Reconnect the ground wire.
(Six)Water heater transformerPower on the display, but the water flow indicator does not respond, the water heater does not heat
(1)The magnetron board is damaged.
Solution: Replace the same type of magnetic control board.
(2)The water supply pressure of the building where the user lives is insufficient.
The solution is to increase the pressure of the water supply.
(3)Water heater water flow sensing core stuck.
Solution Clean the magnetic core.
