With the onset of cold weather, the owners of suburban real estate raises the question not only of insulation of the house, but also of the safety of household appliances. Water-handling devices such as dishwashers are particularly vulnerable. Left for the winter in an unheated room, the equipment can seriously suffer from low temperatures if not properly prepared. Water, turning into ice, expands and is able to break the internal highways, pumps and valves, which will lead to expensive repairs or complete replacement of the unit.
The process of conservation requires careful approach and compliance with a certain sequence of actions. You canβt just turn the device off and close the door. Winter conservation This involves the complete removal of fluid from all nodes of the system, including hidden cavities that are not visible during normal inspection. Ignoring this rule is often fatal to the technique, as even a small amount of residual moisture in severe frost can cause critical damage.
In this article, we will discuss in detail all the stages of preparing your dishwasher for winter downtime. You will learn how to properly drain the system, how to process seals and whether it is worth dismantling some elements. Properly carried out works will allow you to simply connect the device in the spring and immediately start its operation without calling the master.
Risk analysis: why water is dangerous for technology
The main enemy of any hydraulic system in winter is the physical property of water to expand when it freezes. Unlike most liquids, the volume of ice is about 9-10% larger than the volume of water from which it formed. Inside the dishwasher Bosch, Electrolux or any other brand there are many narrow tubes, pumps and valves. Even a microscopic drop left in the hose bend or in the solenoid cavity will create enormous pressure on the walls when it freezes.
The consequences of such expansion could be catastrophic. The plastic housings of the pumps crack, the rubber valve membranes break, and the metal heat exchangers deform. Often, the damage is hidden and only manifests itself after connection in the spring, when the launch attempt leads to leakage or short circuit. Repairs It may be more expensive than buying a new car.
β οΈ WARNING: Even if you plan to come to the country house on the weekend in winter, do not leave the car filled with water. The temperature can drop dramatically in your absence, and the defrosting system will not have time to work.
It is important to understand that modern models, even the most expensive ones, are not designed to be stored at negative temperatures with water inside. Manufacturers indicate in Technical Data Minimum operating and storage temperature, which is usually +5Β°C. Below this threshold, the risk of moisture crystallization begins.
Tools and consumables preparation
Before starting to dismantle and drain water, it is necessary to prepare the workplace and tools. You wonβt need complex equipment, but having certain items will make it much easier and avoid contamination of the floor or furniture with residues of water and dirt.
First of all, provide access to the back wall of the device. This may require moving the car away from the wall or cabinet. Be careful not to damage the floor covering. Also prepare a water collection tank as it can reach several liters, especially if the machine has been connected to the water supply.
- π οΈ A dilution key or set of wrenches to detach the hoses.
- πͺ£ Wide capacity (pelvis or bucket) with a volume of at least 5-7 liters.
- π§½ Absorbent rags or sponges to remove residual moisture.
- π¦ A flashlight to inspect hard-to-reach places inside the enclosure.
- π§΄ Silicone lubricant for processing rubber seals.
Presence silicone lubricant It is critical to maintain the elasticity of rubber parts. During the winter, rubber can dry and crack, especially in conditions of temperature changes. Handling cuffs and seals will extend their service life and ensure tightness at the next run.
Use an old needleless syringe to pump water from hard-to-reach areas inside the car where the cloth is missing.
Disconnection of communications and water drain
The first and most important step is to completely disconnect the device from all communications. Safety should be a priority, so all work begins with a power outage. Find the circuit breaker responsible for the kitchen or specifically the dishwasher and move it to the off position.
After the power outage, shut down the water tap. It is usually located on the pipe under the sink or near the place of the hose insert. If there is no separate tap, you will have to block the water in the entire suburban water supply system. Then the sleeve must be removed. Substitute the prepared container, as water will pour out of the hose and the body of the machine.
The next step is to turn off the drain hose. It can be connected directly to the sewer pipe or through the siphon of the sink. Carefully remove the clamps and unplug the hose. It is important to drain water not only from the hoses, but also from the car itself. For this, many models have an emergency drain or require a tilt of the body.
Sequence of disconnection:1. De-energize the network (automatic).
2. Shut off the water (vent).
3. Unscrew the junction hose.
4. Disconnect the drain hose.
5. Drain the remaining water from the car.
If the design of your model Miele or Siemens There is an emergency drain through the filter, use it. Open the door, remove the bottom basket and find a filter at the bottom of the sink. Substitute the container and open the valve or simply tilt the machine so that the water goes out by itself.
βοΈ Shutdown checklist
Removal of residual moisture from internal nodes
After the main drain, a significant amount of water remains inside the machine. It is located in the circulation pump, heat exchanger and bends of internal pipes. Just turning the car upside down is not enough, especially for heavy models with metal walls.
The purging method can be used to effectively remove moisture. Take a compressor or even a powerful car pump (with caution) and blow the system through a fill hose. This will help to displace water from the pump and sprinklers. If there is no compressor, you will have to rely on gravity and absorbent materials.
Clean all available surfaces inside the camera. Pay special attention to the bottom, niche for salt and rinse. In these depressions, water stagnates most often. Use dry rags or paper towels, soaking moisture until the surfaces dry completely.
| Car assembly | Difficulty draining | Deleting method | Risk of freezing |
|---|---|---|---|
| Circulation pump | Tall. | Purge/Slope | critical |
| heat exchanger | Medium | Gravity. | High-pitched |
| Flush valve | Low. | Wipe | Medium. |
| Bottom of the camera | Low. | Absorption | Low. |
Complete removal of water from the circulating pump is the most critical point of conservation, as its body most often bursts when frozen. Make sure there is no moisture in the impeller by scrolling it manually (if there is access) or blowing it thoroughly.
Handling of seals and preservation of doors
Rubber seals around the perimeter of the door are the elements that are subjected to the greatest loads. In winter, in dry air and cold, rubber loses plasticizers, becomes hard and brittle. In order to avoid detecting cracks through which steam and water will go, it is necessary to carry out preventive treatment.
Use a special lubricant for rubber seals or regular glycerol. Apply the composition in a thin uniform layer on the entire surface of the rubber. This will create a protective film that will retain the elasticity of the material throughout the winter. Do not use petroleum products such as petroleum petroleum or engine oil, as they can destroy the rubber structure.
The important point is the position of the door during storage. Many people mistakenly close the car tightly, believing that this way dust will not get into it. However, this leads to mold and an unpleasant smell due to lack of ventilation. The door should be left a little open.
How to lock the door in an open position?
Use a wooden bar or a special plastic strut so that the door is fixed in a semi-open state (a gap of 5-10 cm). This will ensure air circulation and prevent the hinges from deforming.
If there are pets or children in the house, make sure that the door is not open. You can use regular fixers if they are provided by the model. Candy or HansaOr makeshift stops. The main thing is to ensure a constant flow of fresh air inside the chamber.
Protection of hoses and external elements
Not only the machine itself, but also the communication needs attention. Hoses left in the cold can crack. If possible, disconnected filler and drain hoses are better to bring in a warm room. If this is not possible, they should be preserved in place.
Dry the hoses inside thoroughly. Blow them or use a long brush with a dry cloth. After drying, roll them with rings, avoiding sharp inflections that can lead to claws. Pack the hoses in a plastic bag to protect against dust and rodents that like to settle in warm places.
Check the condition of the rough cleaning filters if they are installed on the water intake into the house. It is also advisable to wash and dry them. The clogged filter can burst when the ice expands, which will lead to the defrosting of the entire water supply system of the cottage on the next arrival.
- π Protect the hoses from rodents by wrapping them in a metal mesh or placing them in rigid pipes.
- π¦ Fold the hoses into a sealed bag with silica gel to prevent mold from appearing.
- π Check the hoses for microcracks and replace them before winter if necessary.
Storage of hoses in a strained state is unacceptable. This creates a constant mechanical stress in the material, which, combined with low temperature, accelerates the aging of the rubber. Leave a small margin of length when stacking.
Dismantling and rolling flexible hoses into a warm room is the best guarantee of their safety, but with proper drainage and packaging, they successfully winter in an unheated country.
Final inspections and spring launch
After all the conservation work, it is useful to inspect the car again. Make sure there are no tools, rags or forgotten parts left inside. Close the niche for salt and rinse so that dust does not get there. If the machine is built-in, check whether its furniture walls are crushed by the thermal expansion of materials.
In the spring, before the first launch, you will need to conduct a reverse procedure. Carefully inspect all nodes for visible damage. Connect the hoses, making sure the density of connections. Only then supply water and turn on the electricity.
The first run is better to conduct in the mode of fast washing without dishes, adding a little citric acid for disinfection. This will help remove possible dust and check the tightness of the system. If the machine is working quietly and without leaks, you can safely load the first batch of dishes.
β οΈ Warning: Do not turn on water heating immediately after cold water is supplied to the system. Let the machine work in rinse mode to warm up the pump and seals gradually.
Following these simple rules will allow your dishwasher to survive the winter without loss. Regular maintenance and proper preservation is the key to the long service of any household appliances in the conditions of suburban operation.
Can I use antifreeze to preserve the dishwasher?
Use of car antifreeze is strictly impossible due to toxicity. There are special food antifreezes for water supply systems, but for a dishwasher it is better to use the method of complete dehumidification. Chemicals can damage rubber seals and sensors, and require multiple washings before use.
Do I need to remove the filters from my car for the winter?
Filters located at the bottom of the camera are better removed, washed, dried and stored separately in a package. This will provide better ventilation of the insides of the machine and prevent parts from clinging to the body. In addition, you will be sure that there is no water left in the filter nets.
What if the car is frozen with water inside?
If you came to the country and found that the car froze, in any case do not include it in the network and do not try to warm with a hair dryer or boiling water. Put the car in a warm room and let it thaw naturally for 24 hours. Only after complete defrosting and removal of water can you try to start the diagnosis, but the risk of breakage remains high.
Are temperature changes dangerous for the electronics of the machine?
Modern electronics are quite stable, but condensate formed at sharp temperature changes can cause a short circuit. Therefore, it is important to let the car warm up to room temperature before turning on after wintering. Also, condensate can oxidize contacts, so a visual inspection of the control board will not be superfluous.
