The new dishwasher came with a drain hose attached. The drain hose then gets detached from the disposal. I used a screwdriver to remove the mounting screws, which attached the tabs at the top of the dishwasher to the countertop.Īfter detaching the hoses, cables and mounting tabs, the dishwasher slid right out of the cabinet opening.
I used an open-end wrench to remove the nut from the compression fitting that held the copper water supply line to the dishwasher. I loosened it to disconnect the drain hose. You can also see the drain hose clamp in this photo. I took the electrical junction box cover off, removed the wire nuts and removed the ground screw. Removing the lower front panels to access water and power connections involved removing four screws. This crowded dish drainer above our old dishwasher indicated why I moved the new dishwasher up the list of home-improvement priorities. This allowed us to pull drain hose slack into the sink cabinet and out of the way of the appliance as it was slid into place.Īfter shutting off the power supply at the breaker box and the water supply under the sink, here’s how I avoided worsening my dishwater hands by installing a new dishwasher: To avoid interference with the larger appliance dimensions, I drilled a new hole in the cabinet partition to route it high enough to avoid using a clamp inside the dishwasher cabinet. The installer of our old dishwasher brought the drain hose into the sink cabinet just below the sink bottom and gained the high point with a clamp inside the dishwasher cabinet. There is also a requirement to avoid a large belly in the hose in the span between the high point and where it connects to the disposal or sink drain. There is a minimum elevation the drain hose must reach in route to the sink cabinet. When installing a dishwasher, pay close attention to the instructions about routing the drain hose.
How to replace a dishwasher hose install#
This will be an advantage for us in a few months when we install the new countertops. The other design feature that was different from the previous generations of dishwasher was the preferred option of anchoring into the cabinet stiles at the sides of the appliance (rather than into the countertop at the top of the cabinet). In our case this meant changing from copper to a braided stainless water line and trimming the power cable to only what was needed. The power and water connections must be made in front, leaving no room to coil extra water hose and power cable. Rather than leaving empty space under the floor of the dishwasher, the capacity was increased by making use of the area just above the floor. One feature gained considerable room inside the machine compared to previous models. There were a couple of design features of the new dishwasher that had impact on the installation procedure. The new dishwasher was the same brand, stainless steel finish and handle style as the fridge-all part of the plan to get matching stainless appliances as part of our ongoing kitchen refresh. I didn’t need to select a dishwasher because we had done that a few months ago when we bought a new fridge. In your own house, you can do it all yourself with a few simple tools. Even with the proper cabinet opening, power source, water supply and water outlet, it still takes a plumber, electrician and carpenter to finish the job. We often joke on the jobsite that a dishwasher is the simplest installation, but it takes three trades to get it done. It didn’t take many meals of hand-washing water glasses, plates, forks, spoons and knives before I was headed to the appliance store to buy a replacement for our old dishwasher. I have plenty of home-improvement projects on the planning board in my office, but this one went straight to top priority. Alternative Heating & Fireplace Inserts.
