Dishwasher Hose

As with any other device of electrical appliance of this kind in our homes, dishwasher related problems can appear.

As we know from other electrical kitchen devices (refrigerator, washer), the most important aspect is the way the dishwasher is sat on the ground. Therefore, when it comes to dishwasher plumbing, the appliance must stand level and always on firmly on the ground.

As you can surely imagine, the surface the dishwasher stands must be clean, free of floor polish and grease. Also, due to the fact that most of the dishwashers on the market come with adjustable feet, you can easily adjust the feet so that the device is on the right position.

Also, in order to avoid any dishwasher plumbing problems, the device must be installed in such a way that no access to live parts or any internal connections with functional insulation is possible.

Yet, no matter how hard you try, dishwasher plumbing difficulties can appear. So, it is most important to keep in mind some important points:

  • the machine must be connected to a different water supply than the kitchen’s supply;
  • connect the device to a tap with 3/4 inch BSP thread termination;
  • never use poor quality hoses and always make sure the hoses are well connected, preferably be means of screw connections with proper hose clips;
  • since the dishwasher will automatically pump water out, the device must be placed 30 cm above the floor;
  • always use a single run of quite high pressure hose, with a 60 bars strength;
  • in the case that you can’t find a solution to your dishwasher plumbing problems you should find a specialist in dishwasher plumbing: yet.

Yet, despite all these dishwasher plumbing measures, several problems may still appear.

In the case of the dishwasher program not starting, it is advisable to check whether the hoses are working properly and if the door is closed. Also, in the unfortunate case the water does not come in, check if the water inlet hose is kinked or even if the tap is turned on.

For any other problems such as unclean dishes, the dishwasher plumbing system has no fault, so you would better check for solutions somewhere else. Several aspects like label recommendations, detergent type, water type play important roles.

Tips to Install a Dishwasher

Most of the people who buy a new dishwasher prefer to pay a specialist to install it. In my opinion, this can be a waste of money, since, if done properly and certain steps are followed, installing a dishwasher can be a piece of cake. But let’s get down to business and find out how to install a dishwasher.

First, if you are replacing a dishwasher, you must uninstall the old one, following the reverse steps we will discuss here. So, before you do any work, you must unplug the device, disconnect the power or turn off the circuit breaker.

After this is done, the water supply valve must also be turned off (this is located at a water supply site, most of the time it’s under the sink) or you can turn off the main house shutoff and open the faucet.

After the old dishwasher is removed, you will have to verify if the old plumbing will fit the new dishwasher. Compare the location and type of connections on the dishwashers to verify that the existing wires and drain and water lines are long enough and correctly positioned for the new unit.

These requirements should be spelled out in the installation manual. Typically, the only problem might be with the water line if you are changing brands.

Also, remember to turn on the water for a few moments to flush any particles out of newly soldered new drain lines. Before you make the connection it is recommended to use some Teflon tape on the threaded pipes ends.

After the dishwasher is installed you must adjust its feet to align with the countertop and cabinets perfectly. After that, you must check for water leaks. Restore the water pressure and then check for leaks or for humid spots.

If this is done, and no problems occur, it is time to install the dishwasher’s front panel. Follow the manufacturer’s instructions to adjust the door so there is an even space on both sides. You might, for example, need to move the door spring to a new mounting hole.

The final test is normally a dishwasher load. After the program is over, and all the dishes are clean, you can say that your mission to learn how to install a dishwasher is done.
