Hitachi Refrigerator Errors with Ice Maker
The following problems and solutions are possible during operation:
- Ice supply has been stopped. Check the available warnings: for example, the child lock is on or the “Water” light is on – the amount of water in the container is getting low, add liquid. The ice supply tube may be clogged and needs to be cleaned. Water may freeze in the tank itself due to the set temperature being too low, the problem is solved by setting the mode.
- The text “On” flashes. The ice tray is in contact with the food in the ice box. The container is not designed for the freezer function – everything unnecessary must be removed.
- Very slow ice making. This problem is always related to the temperature inside the device. There may be several reasons for this: the temperature is set incorrectly; the refrigerator is installed near the heater or the doors are usually opened, filling it with hot air; After purchasing, you immediately check the operation of the system, it has not yet had time to cool.
If serious faults are found in the Hitachi refrigerator, unplug it, consult a professional. It is not recommended to carry out diagnostics and repairs independently. There is a flammable refrigerant inside, if the system is accidentally damaged, its leakage can have serious consequences.
