Installation of a dishwasher might become a very complicated “do it yourself” project. This type of house appliances is a combination of a few totally different systems – water, electricity, heat and steam are joined together, and any little error can cause safety issues. This article’s goal is to build a methodological approach to the installation of the dishwasher.
What do we check before the installation?
The plumbing compartment:
– The water line. In older buildings and houses copper pipes are often used to provide water supply for the dishwasher. These pipes have limited mobility (if you need to pull a dishwasher out of the cabinet for service or repairs, most probably you will end up disconnecting the water pipe), the connectors tend to leak (especially if you disconnect the water line and connect it back more than once).
* Useful tip – replace the copper pipe with a flexible water line . Make sure that the line extends out of the cabinet about two feet (to provide better mobility for potential service needs)
– The drain nozzle – that’s a special fitting you connect the dishwasher drain hose to. Usually it sits on the plumbing pipes under the kitchen sink. If you do not have it – there is possibility to install it by yourself.
The electrical compartment:
– The electrical line for the dishwasher is usually a direct connection of 120 volt – a triple wire connects to three dishwasher contacts. Dishwasher contacts could be either three wires which have same colours as three external electrical threads, or “push in” terminals where a golden receptacle is for a “hot” (black) wire, silver is for neutral (white) and bronze or green is for the ground.
– Double check the “power off” in the electrical line before starting installation;
– The proper connection by the colour is important for safety of the installer and the appliance;
– Never use tape to “hardwire” the contacts! You could look for proper connectors in the installation kit of the dishwasher or use “wire nuts” (aka marettes);
– If you install a dishwasher in a new built house and after installation when the connection is done properly, the machine is refusing to turn on – you may need an electrician to connect the wires into the breaker inside the breakers board. Builders sometimes prefer to leave the line with exposed wires deactivated to prevent potential accidents.
The kitchen cabinet:
Dimensions of the cabinet are supposed to allow proper fitting of the appliance and its accessories. It should also provide base for supporting brackets which anchor the dishwasher to the walls or the countertop.
– If you need to drill holes for a waterline and a drain hose passage, make sure the holes are located close to the back wall. If the holes are closer to the front, they might get smashed by the dishwasher body.
– The drain hose hole could be drilled higher than level of the drain nozzle under the sink. When the drain hose comes from above, the drainage during the cycle is more efficient.
– Anchoring brackets that are screwed to the counter top, should not hold the weight of the dishwasher. Extend the levelling legs to proper height, otherwise brackets will get broken and the dishwasher will become unstable.
