How to Fix a Broken Mounting Bracket on a Commercial Dishwasher
In this guide, we'll explain how to identify, assess, and fix a broken mounting bracket on a commercial dishwasher. This process helps you avoid costly downtime, maintain hygiene compliance, and extend the lifespan of your kitchen equipment.
Understanding the Importance of Dishwasher Mounting Brackets
Dishwasher mounting brackets are designed to anchor the unit to surrounding surfaces—typically countertops or adjacent walls. In a busy commercial kitchen, vibrations, moisture exposure, and frequent loading can weaken these brackets or their fasteners.
When mounting brackets fail:
The dishwasher may shift, causing misalignment with the drain and water connections
Repeated movement can damage hoses, seals, or surrounding cabinetry
The unit may tilt, leading to uneven washing and draining
Addressing the issue early helps prevent equipment wear and water damage, keeping your kitchen running efficiently
Signs Your Commercial Dishwasher Mounting Brackets Are Broken
Mounting brackets keep your dishwasher stable and properly aligned. When they fail, the appliance may shift, tilt, or vibrate more than usual. Catching these signs early can help prevent bigger issues like leaks or door misalignment.
Common signs include:
Unstable dishwasher movement during loading/unloading or cycles
Visible gaps between the dishwasher top and the countertop
Dishwasher door rubbing or catching, due to a tilt
Unusual vibrations or rattling sounds
Water leaks from the hose strain or improper alignment
Steps to Fix Broken Mounting Brackets on Commercial Dishwasher
A broken or loose mounting bracket can cause your dishwasher to shift, tilt, or leak during use. Fortunately, fixing it is simple if you follow the right steps. Here’s how to safely stabilize and secure your dishwasher back in place.
Before working on any appliance, safety comes first. Turn off the dishwasher's power source and shut off the water supply valve. If the unit is hardwired, ensure the circuit breaker is switched off.
Gently slide the dishwasher out from its installation cavity. Be cautious of the water and drain hoses—do not tug or bend them. Place towels or a shallow pan underneath to catch any residual water.
Mounting brackets are usually located at the top (for under-counter installations) or on the sides (for side-mounted units). Look for:
Cracks in the bracket metal
Bent or loose screws
Corrosion from moisture exposure
If the bracket is still present but damaged, remove it for replacement.
Install the new dishwasher mounting brackets:
Align them with the pre-drilled holes on the dishwasher frame
Secure using appropriate screws (included with the replacement kit)
If the original screw holes are stripped, drill new pilot holes slightly offset
Ensure the brackets are tightly fixed and positioned symmetrically to avoid tilt.
5. Re-Level the Dishwasher
Before sliding the dishwasher back in, use a level to adjust the legs and ensure proper alignment. An uneven unit can strain the brackets and create long-term performance issues.
With the new brackets in place, carefully push the dishwasher back into its enclosure. Use the mounted bracket arms to anchor the unit:
For top-mount: Screw the brackets into the underside of the countertop
For side-mount: Screw into the cabinet wall or adjacent surfaces
Use stainless steel screws to prevent corrosion and ensure long-term durability.
Once mounted securely, reconnect the water line, drain hose, and power source. Turn the water back on and restore electricity. Run a test cycle to ensure stability, proper alignment, and leak-free operation.
Tips to Keep Your Dishwasher Mounting Brackets Secure for the Long Haul
Keeping your dishwasher brackets secure isn’t just a one-time fix—it’s part of long-term maintenance. Follow these expert tips to ensure your repair lasts and your dishwasher stays stable through every cycle:
Use exact-fit hardware. Always choose brackets that are specifically designed for your dishwasher model. For long-lasting performance, get high-quality, compatible parts from trusted sources like PartsFe.
Don’t overtighten. Screws that are too tight can strip wood or metal mounting points. Secure the bracket firmly, but stop once it’s snug and aligned.
Inspect during maintenance. Periodically check the brackets during cleanings or filter checks to catch early signs of loosening or rust.
Protect from moisture. Seal around your countertop and use stainless steel or moisture-resistant screws to prevent corrosion and maintain bracket strength.
