You open the door of the dishwasher, and instead of the clean and shiny plates, there are still dirty dishes with food leftovers and soapy divorces. The view is unpleasant and sad. But do not rush to look for signs of a malfunction in your “helper” – it is likely that the problem is caused by commonplace reasons that you can eliminate yourself!
The problems associated with improper use of dishwashers:
The remains of food and sugary food. If you do not remove all this from the dishes, then the quality of the sink will not be perfect. This rule is warned by all manufacturers, and it is recommended to comply with it.
The wrong mode selection. Economical and short programs are intended only for low-level contamination, and fatty utensils require the longest cycle with maximum temperature.
Overloading the machine. If the dishwasher does not wash the dishes properly, it’s possible that you load too many plates and other utensils into it. Try next time to put less dishes – most likely, your problem will be solved.
The improper use of detergents. The wrong choice of cleaning chemistry and / or its quantity is a common cause of poor-quality dishwasher. Try to reduce or increase the amount of rinse aid or even completely change its brand.
If all these manipulations did not lead to a positive result, and your dishwasher still badly washes the dishes, you’ll have to get to know it better and you have to become acquainted with its internal device too. Some problems arise as a result of regular use of the dishwasher and can be completely solved without involving specialists.
The problems associated with the active use of dishwashers:
The scum. Perhaps, this is one of the most insidious enemies of dishwashers. The scum appears because of the hard water (even despite the use of special softeners), it is not visible on the plastic parts of the machinery, but inside, where the parts are metal, scum is slowly collected. Settling on sprinklers, the scum prevents the spraying of water, and as a consequence – the dishwasher does not wash dishes. To eliminate this problem, you need to fill in the machine with citric acid instead of a detergent and drive it out in idle mode with the maximum temperature.
The blockages. The cause of blockages are the remains of food, particles of napkins and other debris that falls on the dishes inside the machine. As a rule, the filters of coarse and fine cleaning, as well as sprinklers, are the most affected by this “disease”. Therefore, if suddenly your dishwasher began to wash dishes badly after long months of good work – first of all it is worth checking the filters. And continue to clean them after each use of dishwashers, as recommended by manufacturers.
So, the filters are cleaned, the amount of detergent is checked by milliliters, the correct mode is selected, and you scraped the dried dirt from the dishes – but the dishwasher does not wash the dishes as before! It seems that you are faced with a really serious malfunction.
All failures can be eliminated only by a skilled repairer who has the profile knowledge, experience and specialized equipment necessary for dishwasher diagnosis and repair. The attempts to repair the dishwasher can lead to a deplorable result – and it is good if the specialist then succeeds in eliminating the consequences of such amateur performance.
In our practice, there were cases when it was necessary to change the “burned” control module due to the fact that before that the client tried to install the thermal sensor himself and did it incorrectly. As a result, the total amount of repairs turned out to be much higher – in fact the control module is the “brain” of the dishwasher.
