Italian dishwashers “Lex” in the Russian market for more than 10 years. During this time, the owners managed to evaluate the quality and functionality of this household appliance. But there are also users who had to deal with device breakdowns. Knowing what this or that error code means, you can determine the cause of the failure on your own. And then make a decision – contact a service center or repair the machine with your own hands. In this article, we will tell you what the errors of LEX dishwashers indicate and how to fix them.
How LEX Fault Codes Are Deciphered
In most cases, when a malfunction occurs, the PMM notifies itself. In some brands of machines, this happens through the display of a code on the display, in others – through the flashing of lights (indicators) on the control panel. In Lex dishwashers, the manufacturer has provided exactly the second way to notify about a problem. The list of codes, although it consists of only two items, but let’s find out how their meaning is deciphered.
If the program indicator “Quick wash» – this means that there are problems with water intake. The chamber fills longer than the time set for this procedure. The cause may be insufficient water pressure or a clogged inlet pipe. Also check the water supply faucet. It may be closed or not fully open.
If the “Glass” washing mode indicator flashes – This is a signal about overflow (overflow). In this case, too much water enters the hopper. The reasons for the error are as follows: the drain system is damaged or there are blockages in it, the pressure switch does not work, or the inlet valve is faulty.
In the event of an overflow, manufacturers recommend shutting off the water supply and calling a service technician.
If the code on the screen is displayed for the first time (in our case, the lights flashed), you can try restarting the device. Perhaps the dishwasher just experienced a system failure, and a reboot will help the electronic module reset all settings.
How to restart the machine:
- interrupt the program (if it is running);
- unplug the power cord from the socket;
- wait 15-20 minutes;
- try turning the device on again.
You can use another reboot method that is suitable for any PMM. Just press and hold the power off button for 10-15 seconds.
What should I do if the restart was unsuccessful and the error reappears? Or even worse, the machine does not signal a breakdown, but it does not turn on either. Why this happens and how to solve the problem, we will tell below.
Causes of breakdowns of the dishwasher “Lex”
Not all the problems that have arisen in the operation of the system are reported by the dishwasher with an error code. It can function normally, but with some “nuances”. The most common cause of breakdowns is improper operation of equipment. This once again confirms the importance of reading the instructions for the device before using it.
Consider the common problems and possible causes of their occurrence that owners of LEX dishwashers face.
PMM does not turn on or the program does not start
Maybe:
- electricity is not connected (damage to the socket, power cord);
- the fuse burned out or the plugs were knocked out;
- low pressure in the water pipe;
- the hopper door is not closed properly.
The machine does not drain waste fluid
What happened:
- clogged coarse filter or kitchen sink drain;
- the drain hose is kinked or clogged with debris.
If a small amount of water remains at the bottom of the sump around the drain hole, do not worry. This is considered normal and does not require intervention.
PMM is leaking
Check:
- dispenser overflow;
- maybe rinse aid has spilled;
- technology is out of whack.
Spilled liquid can cause excessive foaming and overflow. Therefore, if the rinse aid is spilled, then the surface must be wiped dry with a cloth.
Dirty dishes after washing
The reasons:
- the camera is overloaded;
- the dishes are placed in it incorrectly, therefore, it interferes with the free rotation of the rocker arms;
- little detergent;
- insufficiently powerful washing program has been selected;
- The filters in the base of the wash compartment are not installed correctly or are clogged.
Poor drying quality
This is because:
- Wrong program selected (too short);
- incorrect loading of the bunker;
- the dishes are being unloaded too quickly.
Noise during operation
Maybe:
- yokes knock on objects in the basket;
- cutlery that is not fixed in the washing compartment rattles.
How to fix such problems, we will tell below.
LEX dishwasher repair
If we analyze the main causes of machine breakdowns, we can conclude that it is not difficult to eliminate them on our own. Consider malfunctions that are solved without the help of a specialist.
Before carrying out repair work, make sure that the device is disconnected from the power supply and water supply.
Elimination of leaks
A frequent and rather unpleasant situation is when a puddle of water is found under the dishwasher. This indicates that it has a leak. You need to act without delay, as high humidity will lead to corrosion and a quick failure of the electronic module. The first step is to locate the leak. Proceed as follows:
- Check the drain and intake system hoses for damage or defects. If they have a crack, replace the parts.
- Check the pipe fittings. Perhaps the clamps are loose, so they need to be tightened better.
- Check the rubber seal on the hopper door for tightness. If the seal is worn out, replace it.
How to replace the door seal, you can see the video below:
If it turns out that the case itself is damaged or the water tank is cracked, then call the master.
Cleaning filters and hoses
Clogged drain and intake systems are the result of improper maintenance of equipment. Systematic cleaning of these important parts will help prevent many unpleasant situations.
To clean the inlet hose and filter, proceed as follows:
- prepare a small container in advance in case liquid flows from the pipe;
- disconnect the inlet hose from the housing;
- using pliers, pull out the filter mesh, rinse it;
- inspect the hose itself, if debris has accumulated in it, clean it too;
- collect the parts, install them in their original place.
Check the operation of the intake valve.
If his coils are burned out, a new part will be required. How to replace it, see the video below:
Also, the drain tract needs to be cleaned, in which food debris can accumulate. This not only disrupts the operation of the drain system, but also threatens to break the pump (drain pump).
The procedure consists of the following steps:
- Pull out the loading baskets, trays from the machine.
- At the bottom of the hopper, find the filter (coarse). Turn it counterclockwise, pull it out upwards together with the grate.
- Rinse all parts thoroughly, then reassemble them.
Regular cleaning of the drain system will help to avoid a similar situation in the future and extend the life of the equipment itself. When cleaning, use only a soft brush.
Solving the problem of poor-quality washing and drying
An unsatisfactory result of washing and drying is also a consequence of improper operation of the machine. The problem may be the following:
- Wrong download. Dishes in the hopper must be placed in such a way that during washing they do not interfere with the free rotation of the rocker arms. Also, do not overload the camera and place objects close to each other. Dishes should be evenly washed with water jets from all sides. Otherwise, the washing quality will be poor.
- Wrong program selection. Select the duty cycle according to the type of contamination. If there is fat on the plates, dried food residues, then set a more intense program with a higher heating temperature and duration. Otherwise, cutlery will have to be washed manually. Drying can also be of poor quality if a too short program is selected.
- Not enough detergent or rinse aid is being used. Try increasing the amount of powder to improve the quality of washing, and the rinse aid to dry the dishes better. You may not be using enough of them, which negatively affects the operation of the dishwasher.
- Clogged nozzles. Pieces of food can block the sprinkler holes and prevent the flow of water. The problem is solved by cleaning. To do this, you need to remove the rocker arms and clean the nozzles of clogged dirt with the help of toothpicks.
Improving the quality of drying is also simple:
- choose the right program (refuse short cycles);
- do not unload the machine ahead of time;
- do not load dishes with low quality coatings into the chamber (in this case, the flow of water will be difficult, therefore drying will be of poor quality).
Elimination of extraneous noise
A characteristic tapping or rattling during washing indicates that the dishes are loaded incorrectly (not fixed or preventing the rotation of the rocker arms). How to fix the situation? It is enough to restart the camera by placing cutlery items in their places:
- glasses, cups – in a special basket (holder) upside down;
- plates – on the grate at an angle so that the water drains better;
- pots, pans – in the lower basket.
Many malfunctions of the LEX dishwasher are fixed easily and without outside help. And if you follow the rules of operation, then most of them can be avoided. Remember that more serious breakdowns associated with the failure of important mechanisms and components are best left to the master. Without diagnostics and the help of a specialist, such amateur activity can further harm your dishwasher.
