The dishwasher mechanism includes a set of devices and sensors, which provide work. In case of failure of individual nodes, the operation of the machine is blocked, preventing startup with a breakdown. The signal of the problem is the flickering of the button combination in older models and the appearance of an error code on the display - in the new technology. The krona dishwasher allows you to detect a problem by displaying a combination of the letter E and a certain number (example, E4).
Deciphering the main errors
During operation of the machine it is possible to face mechanical failure of some elements. An error may also occur due to a failure in the control system. If the unit is in working order, start the self-diagnostic system, then the problem code will be determined. Knowing the decoding of the character combination, it is possible to define a site of breakage and to try to eliminate defect by own forces.
If there is a need to replace the part, which requires disassembly of the case, it is better to consult a specialist. Power failure of the equipment also requires some knowledge.
Manufacturers of different brands use different fault coding, but some of them are very similar. Crown washing units have a number of similar errors with the Hansa dishwasher. The most common fault codes are as follows:
- E1 - triggered protection against leakage in the form of lack of water in the dishwasher.
- E2 - drain time exceeds the allowable value, or insufficient water pressure.
- E3 - water is not heated to the required temperature.
- E4 - excessive amount of water in the tank.
- E5 - de-energized thermistor.
- E6 - E7 - power supply of heating units is broken or absent.
Checking the power supply of heating units
What to do if error E4
When determining the fault code E4 in the dishwasher crown or Hansa in the washing unit there was an overflow of water. This circumstance can be provoked by several factors:
- water level sensor malfunction;
- valve damage.
Elimination of breakage is carried out by replacement of faulty elements. In this case, it is safer to use the services of the service center, as it is necessary to disassemble the design of the unit. Of course, you can find video instructions for repairing a dishwasher on the Internet and use it, if you have experience in troubleshooting technology. Example, this video will tell, how to check the water bay valve yourself
Kitchen detergents are spreading with acceleration, as it greatly simplifies the assembly process and saves valuable time. Like any technique, the dishwasher requires careful care. Improper operation impairs the functionality of the working units, which may render it unusable.
