How to replace and extend dishwasher hoses

Modern science does not stand still; the days of spending a long time in the kitchen in front of the sink are a thing of the past: the tedious washing of dishes by hand has been replaced by an automated machine. Dishwasher has rightfully become an important attribute in the kitchen, so its purchase is a kind of holiday for housewives. Connecting the “dishwasher” is the main step before putting it into operation. It is important to familiarize yourself with its characteristics and instructions for use before starting to use it.

Hoses dishwasher: The filler and drain must be included. The manufacturer gives them a good warranty, so factory defects are extremely rare.

There are all sorts of circumstances in life: it may turn out that hoses are not included in the components; either they will be short; or a defect has arisen, and one of them has become leaky and needs to be replaced. In this case, it is useful to know how you can select a hose, replace it, or lengthen it.

Characteristics of water supply hoses

In activity dishwasher Hoses (sleeves) for supplying cold or hot water inside the unit play a major role, without them the machine will not work.It is important to recognize the defect in time and take measures to eliminate it. The drain line also plays an important role: it performs the function of discharging dirty water after the end of the dishwashing cycle. If deviations occur in the operation of this hose, the speed of operation may decrease, an unpleasant odor may appear, or the equipment will stop working.

Before purchasing it, it is advisable to decide on the length and calculate the distance from the sink to the washing mashine. It must be remembered that the hose cannot be connected using the tension method, as mechanical defects may occur in the future, which will lead to water leaks. Sleeves are available in lengths from 1.5 to 5 meters, the most optimal length is 2-2.5 meters, they are sold by the meter.

Zinlet hoses have a technical passport, which includes all their characteristics: maximum permissible water pressure, operating pressure and temperature. The numbers are indicated on the sleeve itself if there is no passport. The water supply hose is usually made of polyvinyl chloride (plastic); at its ends, parts with a union nut are installed for connecting pipes - fittings. These parts can be angular (they are usually used for fastening in the dishwasher) and straight. There are rubber and reinforced filling hoses. Rubber – additionally reinforced with nylon or metal. The most popular are plastic sleeves; buyers are especially attracted by their price, and besides, they are quite practical.

Typically, the operating temperature of hoses in cold water is 20-25⁰C, hot – 60-70⁰C. For apartments choose filling hoses designed for pressure up to 20 bar, for private houses and cottages - by 10%. more.Some water supply lines are equipped with a special design that protects the dishwasher from leaks - the Aquastop valve. The cost of such systems is several times higher than conventional designs. If desired, this sleeve can be installed instead of the drain sleeve, this will significantly increase safety and reliability. It is advisable to install filters in place of the drain sleeve before installing the system with the Aquastop device, which can hold dirt and prevent blockages. This will extend the service life of the machine The drain sleeve is made of polypropylene, the length is up to 5 meters. When choosing it, it is necessary to take into account that the diameter of the pipe outlet must match the diameter of the fittings for connection. You need to know that if the drain line is made in a telescopic design, then the corrugation will stretch, and it can not be extended in case of insufficient length. In case of water leaks from the sleeves on the dishwasher, it is advisable to completely replace them, since the repair and sealing will not last long. Replacing the hoses on a dishwasher.

To prepare the dishwasher for replacing the hoses, you need to: disconnect it from the power supply (check the display to make sure it is inactive), turn off the water supply valve, lay out a large rag or cellophane in case of draining the remaining water, disconnect from the sewer. Tools for the job - pliers, screwdrivers, adjustable wrench, impact wrench.

When everything is prepared and the hoses of the required length are purchased, you can, if possible, pull out the machine and disconnect the lines.

Replacing the inlet hose

Replacement is quite simple: you need to carefully unscrew the hose nut, move the old hose to the new one, and tighten it.

There are models of “dishwashers” in which the water fill line runs inside the body of the model. In this case, a small disassembly of the case is required; the washing mashine should be turned over or placed on its side, this will be more convenient. It is necessary to disconnect the front strip from below and the bottom itself. As a result, there will be access to internal components. At the front wall of the housing, the sleeve is connected to the fill valve; it must be disconnected from the valve with a wrench, a new one must be installed and screwed on. If you want to install Aquastop protection, it is important to know that it comes complete with the sleeve and cannot be installed separately.

Replacing the drain hose

The drain hose is connected to

dishwasher

If all communications are disconnected from the dishwasher, in order to clean or replace the sleeve, unscrew the screws on the lower front wall with a wrench, then remove the panel and plate. Next, we proceed to the junction box: remove the wires and remove the cover. Remove 2 screws from the brackets securing the dishwasher in the hole in the niche where it is installed. The machine can be pulled out from under the rack, but for this it is necessary that the filler and drain lines sag well: it is advisable not to damage them. Unscrew the clamps using pliers. It is best to place the washing mashine on its side, unscrew the screws, and remove the pan.

In Bosch and Garenier types, a float sensor is attached to the pan, so first of all it must be disconnected and removed.

We loosen the clamp and remove the end of the hose from the seat in the circulation pump structure; the remaining water may drain out. We remove the check valve and place it in the pump, after which we remove the back wall of the equipment. Disconnect the sleeve holding the hose. We replace the drain hose with a new one.

How to extend dishwasher hoses If there is a need to lengthen the hose due to a change in location of the dishwasher or for another reason, then you need to have an idea of ​​its technical characteristics, calculate the length by which you want to increase the diameter, and purchase a filler or drain hose with the required parameters. To work, you will also need a coupling and three clamps.
