Errors of the Crown Dishwasher - Codes, Values

Does the "Crohn" dishwasher give an error code? When the icons light up on the display, the self-diagnosis system informs you of a fault. But how do you know where to look for a malfunction? For this, the instructions indicate the decoding of all errors. In our publication you will also find an explanation of these symbols.

We will tell you how to fix the malfunction and restore the work of the MMP.

We determine the meaning and ways to eliminate the errors of the dishwasher "Crohn"

As soon as the board displays a trouble code, do not rush to panic. If there is no other sign of a breakdown, try resetting the error. What do we have to do:

  • disconnect the equipment from the network for 10-15 minutes;
  • Start the car again and look at the screen.

Are the icons on the display? So, this is not a system failure, but a technical problem that requires elimination. You can try to manage on your own.

Consider the malfunction of Krona dishwashers.

Error code Value Causes of appearance How to fix the problem
E1 Water does not enter the hopper.

The protection of "Aquastop" was activated. It works if there is a leak. Located on the inlet hose.

Access to water is blocked until the problem is resolved.

Carefully inspect the body of the machine, check the connections, the integrity of the hoses and nozzles. See if the water is leaking from the door: the seal may be worn out. Replace defective components.
E2 The water does not drain. Why MMM "Krona" can show this error:
  • the drain filter is clogged;
  • the drain hose was blocked;
  • the impeller of the pump or pump is blocked;
  • problems in the work of the pressure switch;
  • The triac of the control module was burnt.
  1. Check hose and filter for blockage.
  2. Inspect the impeller of the pump. It could be blocked by a foreign object. If the pump fails, the pump must be replaced.
  3. Carry out a fault finding procedure for the level sensor. If it gives incorrect readings about the water level in the bunker to the electronic module, then the board does not give a command for draining.
  4. The triac, which controls the pump, is defective. Need repair or replacement module.
E3 There is no heating. Causes:
  • there were malfunctions with TEN or its wiring;
  • Thermal sensor broke;
  • malfunction of the electronic controller.
What to do:
  1. Check and replace the heating element in case of malfunction. Inspect the wiring and look for tanning, insulation damage.
  2. Carry out a diagnosis of the temperature sensor and install a new one.
  3. Repair the controller (contact the master!).
E4 The system "Aquastop" has worked. Too much water in the dishwasher. What is the reason:
  • problems with the intake valve;
  • malfunctions with the pressure switch.
How to fix the situation:
  1. Check the solenoid valve for damage. The electronic part is diagnosed by a multimeter: attach its probes to the contacts of the part, measure the resistance. Install the new valve.
  2. Replace the pressure switch, it is not subject to repair.
E5 Closed the NTC sensor. The thermostat does not give a signal. Cause:
  • short circuit;
  • burnout of contacts;
  • sensor failure.
Diagnosis and replacement of a thermistor or wiring harness.

E6

E7

The thermistor circuit disconnected. The heater is defective. Heater contacts are broken. Inspect the heating element. Install new serviceable parts.
E9 There is no signal from the heater, or it does not work. There was a break in the heater due to a short circuit or other causes. Most often this affects the flow element, built into the circulation unit. Diagnosis of the part. How to replace the heater, read in a separate article.
E10 The dishwasher works without heating. The integrity of the drying is broken. It is recommended to call the wizard or contact the service center.
E11 The technique works with cold water. There is no heating. Defective:
  • temperature sensor;
  • control module;
  • pressure switch;
  • wiring.
Diagnosis and installation of serviceable parts is required if:
  1. The thermistor does not measure the temperature of the water.
  2. Pressostat does not inform the board about the water level in the bunker, the heater does not turn on.
  3. Blown circuit, broken contacts.
E14 Incorrect flow sensor operation.

The consumable element is installed in place of the pressure switch. If there is an error E14, then it does not receive control signals, although the circulation pump receives them.

Causes:

  • the integrity of the wiring is broken;
  • problems with the electronic card.
What can you do:
  1. Replace the broken items.
  2. Inspect the fee for damage.
E15 The leakage protection has tripped. There was a leakage of water, or "Aquastop" out of order. Available Solutions:
  1. Elimination of leaks.
  2. Replacement of the system "Aquastop".
E16 When taking water, an error occurred. Causes:
  • problem with the flow sensor;
  • too high pressure.
Inspect the sensor. Wait until the pressure returns. Try installing a non-return valve.

Knowing all the decoding errors of MMC "Krona you can try to find and fix the problem yourself. On how to disassemble the dishwasher, read in our article.
