Faults of ice makers: causes, repair by their own hands

click fraud protection

Ice machines are used in everyday life and in professional kitchens to create ice cubes. You fill the water, press the button and get a big batch of ice - conveniently at parties. But even with such simple devices there are malfunctions. You can call the master, or you can try to figure out how to troubleshoot the ice maker.

Ice maker problems

Let's consider typical breakages, and also we will find ways of their correction.

The drain hose or the sewer system is blocked.

The principle of connection and operation of a drain hose in an ice machine is similar to a washing machine, but blockages occur much more often. In this case, you can see water inside the camera and unfrozen cubes. Causes of clogging:

  • Cooling in the chamber of drinks and products. Particles of food and fricates fall into the sink.
  • Incorrect hose connection - below the required level.

How to clean:

  • Disconnect the hose and rinse under the pressure of water.
  • Repeat the connection by placing the element at least 45 cm from the floor.
  • Elimination of sewage clogging.

The device is designed only for the conversion of water into ice, and not for cooling and storage of products.

Problems with the programmer, the valve and the thermostat

You noticed that the ice is trapped in pieces on the evaporator. The defrost cycle does not start. First turn off the device and reboot.

Causes of problems and ways to solve them:

  • The programmer. The thermostat sends a signal to the control module, which starts the freeze or defrost cycle. If the processes do not start within 12 minutes, perform the diagnostics. To do this, turn the programmer shaft into defrost mode. If the freeze is activated, the element must be replaced.

  • Evaporator thermostat. It signals the temperature in the chamber to the module. To check, press the spring of the part from the back side. Measure the resistance with a multimeter.

  • Solenoid valve. To freeze the liquid, the valve closes the refrigerant current to the evaporator. Before starting the defrost, it opens, letting the hot stream into the evaporator. To check for a defrosting coil, a current is applied to check whether it opens or not. The resistance of the frost coil is measured.

Blockage in the injectors or malfunction of the pump (water does not flow)

The characteristic signs of the malfunction are the irregular shape of the ice or incomplete filling of the molds.

The pump is used to inject water into the compartment, which flows through the nozzles. If the water does not go, then there is a blockage that needs to be eliminated.

Independent repair:

  • The water collector is dismantled.
  • Clean the filter and injectors.
  • The pump is checked. If a problem occurs, it is replaced.

Opaque cubes are produced

This happens when using hard water, which contains a lot of lime and calcium. If there are a lot of impurities in your area, be sure to install a cleaning filter.

Malfunction of thermostat or circuit breaker

If the ice maker does not turn on or turns off after 15 minutes of operation, it is likely that the bunker thermostat defect has occurred. At the same time, ice is not produced, or the pressure switch is turned off in emergency mode.

The bunker thermostat is used to control the production of ice. As soon as the temperature in the chamber reaches a certain mark, the device is disconnected from the mains.

What to do:

  • Inspect the regulator.
  • Check whether the shut-off valve is open.
  • Inspect the solenoid valve, fan, condenser.

The evaporator does not freeze

During the suction, the pressure is higher than normal. The water or solenoid valve may be open. The elements are checked and replaced.

Evaporator badly freezes

Probably, the pressure is lower than the norm. This happens as a result of clogging the capillary or leaking refrigerant. It is necessary to find and eliminate blockage, and also to check the condition of the filter-drier. Eliminate leaks and refill the system with refrigerant.

Ice is produced longer than usual

If the cycle lasts longer than half an hour, half the cubes are irregular in shape, then the radiator is clogged (actual for air-cooled generators). The radiator needs to be cleaned urgently. For this:

  • Remove the service hatch.
  • Unscrew the screws, unfasten the front panel fasteners. Remove it from the case.
  • Clean the radiator with a brush and air flow.
  • Replace the panels.

No water in the cell, no ice

Even if the cubes are formed, then the irregular shape. Water is not enough to fill the molds completely.

  • Check the fill valve of the filling hose. Open it to full capacity.
  • Problems with the operation of the solenoid valve. In this case, you need to replace the element.

Unstable operation of the pump

Water enters the chamber intermittently and unstable. It is necessary to clean:

  • collector,
  • filter,
  • injectors.

Diagnose the pump failure, install a new part if necessary.

Water overflow in the chamber

In this case, the shape for ice can not be closed from too many cubes. This indicates a malfunction in the operation of the thermostat, which controls the amount of ice in the compartment. Install a working part and run a test run.

Water under the hull

There is a leak in the solenoid valve. It is necessary to eliminate the leak or replace the part.

The cabinet is shocked

If, when touched, the ice maker beats current, then the connection was made without grounding. Install a damped, grounded outlet, check the power cord and extension cord.

Noisy operation of the unit

When noise and whistling are heard during the operation of the generator, the condenser micro-motor is probably worn out. It is not recommended to lubricate and repair, it is better to replace immediately.

The indicators on the panel flash

The indication tries to inform you about the problem. Look if there is enough water in the tank, if the mold is full of ice. If the blinking does not stop, it is better to contact the master.

To avoid such problems, we recommend that you follow the rules of operation:

  • For refueling you need to use purified water. If it is filled automatically, install a clean filter.
  • Change the water in the tank you need every day.
  • If the motor stops working, do not restart the unit immediately. Disconnect it from the mains and let stand for 15-20 minutes. Then turn it on again.
  • Clean the hopper with a solution of soda.

Now you know how to react when a problem occurs. If you use an ice machine by the rules, then you do not have to deal with the consequences.
