What is the worst thing in a kitchen?

The gap between the dishwasher and cabinet. Period. Although the dishwasher brings loads of convenience for you, it can also disrupt the alignment of the cabinet and the countertop.

A misfit dishwasher looks incompatible with the kitchen layout. If the gap is more than 2 inches, you better wear ear muffs to block the noise while working in the kitchen.

If you want to fill the gap between the dishwasher and cabinet, you need to take the cabinetry and countertops into consideration and perhaps adjustable legs too.

Here you will find some easy ways for you to have a better-fitting dishwasher at your service.

If the space around the dishwasher is too big, it will make noise because it allows the sound of the motor out. The solution is to get a dishwasher that fits the frame but not without following these steps first. 

Measure The Gap

A dishwasher is supposed to be installed in a 24’’ wide opening. When the dishwasher is fully gathered in the space, first calculate or estimate the gap on either side of the appliance. Measure the height between the underside of the counter and the top of the toe kick with a measuring tape to determine or establish the availability of space on either side.

Take the measuring tape and place it vertically down so that you can take the right measurements. Usually when the gap between the dishwasher and countertop is 1 inch the steam has space to escape which can cause damage to the cabinet doors. 

Raise Dishwasher

Another way to fill the gap between the dishwasher and cabinet is to lift your dishwasher. You might want to consider doing so if you wish to close the clearance or gap, but your dishwasher’s feet have already reached their highest point. The length, width, and current gap height all affect the plywood’s thickness, while the dishwasher’s base size affects the plywood’s length and width. This is where adjustable legs come into action. Just twist the adjustable legs of the dishwasher counterclockwise until the gap is filled. 

If your dishwasher has one, a new panel for the toe kick will need to be fitted because of the extra height. The dishwasher’s door is typically elevated somewhat above the remainder of the unit. The dishwasher and countertop can thus be spaced apart just a little. But you won’t need to see it because of the door.

Use Shims to Elevate Dishwasher and Countertop

The result is to raise the dishwasher, so there isn’t a noticeable space between the dishwasher and the cabinet. Leg adjustments are the simplest solution which has proven helpful in removing the gap between the dishwasher and cabinet. So, you’ll have to assist yourself in rising a little higher. First, measure the gap to determine how high to raise the dishwasher. Then you can attach a plywood piece to either side.

In every decision, you will need two large pieces of wood to install on both sides. The additional board of wood should then be positioned below both left-side legs. Because it offers the most stability, this is essential.

Use Sandpaper to Sand The Wood

Using a hand saw and your calculated results, rim a thick piece of appearance-grade lumber. Take hold of the board in the area to check or determine if it is adjusted correctly. Start using medium-grit sandpaper to smooth the cut edges as soon as the wood fills the space without settling too firmly or leaving a gap.

Paint The Piece of Wood

To match your existing cabinetry, it is time to stain or paint each piece of wood in line with the manufacturer’s recommendations. Allow the pieces to dry completely for at least 24 hours.

Limit how high you raise the dishwasher. A small gap is required to allow heat and moisture to escape without harming your cabinets. Additionally, you might prevent the dishwasher door from opening. Just take care to lift it as high as is necessary to cover a wide gap.

Secure Panels with L-Brackets and Screws

With wood screws and a screwdriver, fasten an L-bracket in the opening. Remove the dishwasher and set the bracket 1 inch from the counter’s underside, with the face of the L-bracket spanning the opening and one end of the bracket positioned in opposition to the nearby cabinetry.

Install 1/2-inch wood screws across the rear of the wood to secure and fasten the wood panel to the L-face. Brackets on the other side, repeat. In line with the manufacturer’s recommendations, install or repair the dishwasher, including the wiring and plumbing.

The use of heat is one of the key components in the dishwashing process. There is a build-up of heat around the dishwasher in the small space under your countertop, whether it is water being heated to efficiently wash your dishes or heating the air to dry your dishes.

Given that steam rises, a gap might be a better option in this situation, allowing warm air to exit the enclosed area. Additionally, it is simpler to raise the dishwasher to the correct height by changing the appliance’s feet.

When is it not a Good Choice to Leave Gap between Dishwasher and Cabinet

While dishwasher space must be cleared, it also serves as a blank canvas for gathering dust around your appliance. Disconnecting the plumbing and electrical systems after removing a dishwasher to clean is a challenge.

If the cabinets in your kitchen are wood, steam that escapes when your dishwasher is opened or from the vent may collect there and result in a steam burn. As a result, your wooden furniture will develop a white film, and your cabinets may eventually need to be replaced.

No Extra Spaces! 

Check for any gaps or openings around the plumbing and electrical lines that can cause a cold draught to form before you seal your dishwasher into the cabinet. After placing your dishwasher neatly under its frame, it won’t be very pleased to find the draught.

You might try adjusting the legs if your dishwasher has a space between it and the surface. For this purpose, most machines include adjustable feet. If it doesn’t work, raise the dishwasher by placing two wooden planks beneath the washer’s legs.

    Calculate the distance between the floor and the dishwasher. Silicone caulk is the best substance to use if the gap is small because it is moisture-resistant. After cleaning the surface, cut the caulking tube's tip at a 45-degree angle and insert it into a caulking gun. Put a bead of caulk continuously the whole length of the gap. That will neatly close the distance.
