Inlet and drain hoses for the dishwasher allow you to effectively operate the equipment. Thanks to them, water is normally poured into the hopper, and then drained at the end of the wash. But if their length is not enough to connect or a leak occurs, problems begin. We will tell you how to properly position, extend and replace the hose in the dishwasher.
Preparation of PMM for repair
The type of water supply hose depends on the model of the dishwasher (Bosch, Electrolux, Hansa, Beko). When buying equipment, it comes complete, connects to a hot or cold water supply and passes water into the chamber. Depending on the type of connection, the product can be designed for an operating temperature of up to 25 ° or up to 70 ° C.
There are such types:
- Rubber standard.
- Reinforced. The rubber base is further reinforced with metal or nylon.
- Rubber with protection against leaks "Aquastop".
The inlet hose must have a technical passport or marking, where such data are indicated:
- Operating pressure. For installation in an apartment - 20 Bar, for a private house the permissible pressure is 5-10% higher.
- Length. The product must not be connected with high tension or kink. This leads to a reduction in service life. Therefore, before buying, find out the distance from the sink to the dishwasher.
As for the drain hose for the dishwasher, it is made of polypropylene. Make sure that the diameter of the fittings for the connection coincides with the outlet of the pipe or siphon.
- The maximum length of the standard version is from 1 to 5 meters.
- The telescopic version will do without elongation, since the corrugated structure can stretch. The inner surface is also uneven, therefore it is subject to frequent blockages.
Prepare the necessary tools and parts and only then proceed with the installation.
You will need:
- screwdriver;
- pliers;
- brass tee;
- filter;
- fum tape;
- clamps.
Next, you need to lengthen or install a new element for the dishwasher.
How to install
If there is a problem with the intake or drainage of water in the Siemens, Ariston dishwasher, the hoses are checked first. If they leak, a complete replacement is required. It is not recommended to repair and seal the damage - this is unreliable and will lead to a serious leak over time.
Prepare the dishwasher. Get the built-in appliances "Electrolux", "Ariston", "Bosch" from a niche. Turn off the water supply and unplug it. Most often, the filling element is connected at the back to the bottom of the housing:
- Unscrew the mounting nut from the PMM housing.
- Disconnect the other end from the water supply.
To properly connect to the water supply, wind a brass tee with a shut-off valve to the pipe outlet. Connect a sink mixer to one terminal of the tee, to the other a flow filter and the end of the inlet hose. The connecting parts are sealed with fum tape.
On some dishwasher models, the connection is inside the cabinet.
- Flip the chassis over to the back.
- Remove the lower bar.
- Turn off bolts and remove the pallet.
- The end of the hose is attached to the filler valve.
- Using the open-end wrench, unscrew the old device and reconnect the new one.
If you need to shorten the length, we do not recommend doing it yourself. It’s better to go to the store and purchase an item of the right size.
To increase the length, you will need a special coupling. It is better to choose not a plastic, but a brass coupling. Connect it to the main hose and fit the extension cord on the other end. Connect the device to the water supply and you're done.
Experts do not recommend lengthening, as this increases the risk of leakage.
How to replace the drain hose? First you need to check for what reasons he stopped performing his function. Perhaps this is a blockage and it is enough to clean it. It can be connected in different places: bottom right or left, top. To clean or swap an item, do this:
- Using pliers, unfasten the plastic clamps.
- Turn the equipment on its side.
- Loosen the screws and remove the lower pan. In the Bosch or Gorenie models, a float sensor is attached to it. Therefore, first disconnect the wiring chip and remove the sensor.
- Loosen the clamp and remove the end from the seat in the circulation pump assembly. Be careful, water may spill out of it.
- Remove the check valve and place in the pump.
- Disconnect the back of the appliance.
- Pull out the sleeve that holds the hose.
- Change to a new element or extend with a sleeve. Do not forget to strengthen the connection points with clamps.
Perhaps a replacement is not needed, just clean the inlet. To do this, use a small brush and a strong pressure of water.
