The Bertazzoni dishwasher water supply hose inspection is a simple annual task that can prevent the kind of slow, hidden leak that causes thousands of dollars in cabinet and subfloor damage before it is ever noticed. The Swedish-engineered DW24PR and DW24XT dishwashers are built to high durability standards, but the supply hose and its connections are wear items that require periodic owner attention.
Why this matters
Water supply hoses operate under continuous mains pressure whenever the home’s water supply is on. Unlike a drain hose, which is only under pressure during cycles, the supply line is always pressurized. A slow pinhole leak or a gradually loosening compression fitting can drip behind the dishwasher for weeks before moisture becomes visible, silently saturating cabinet bases, hardwood subfloors, and adjacent cabinetry. On integrated installations where the DW24PR is panel-faced, these leaks are particularly difficult to detect without a deliberate inspection.
Warning signs
- A damp or musty odor in the cabinet beneath the sink adjacent to the dishwasher
- Warping, soft spots, or discoloration on the cabinet floor directly beneath or beside the dishwasher
- Visible mineral deposits or water stains on the supply hose body or at either connection point
- A subtle reduction in fill water sound during the wash cycle, which can indicate a partial supply restriction from a kinked or pinched hose
Inspection schedule
Inspect the water supply hose and both connection points annually. Braided stainless supply hoses in good condition typically last five to seven years; rubber hoses should be replaced at the five-year mark regardless of visible condition. If you do not know the age of the current hose, replace it as a precaution.
What to do
- Turn off the water supply valve beneath the sink before accessing the dishwasher’s supply connection.
- Using a flashlight, visually inspect the full length of the supply hose for bulging, cracking, mineral deposits, or discoloration.
- Check both connection points — at the valve and at the dishwasher inlet — for drips, calcium buildup, or corrosion on the fittings.
- Confirm the hose is not kinked or pinched behind the appliance where it routes under the counter.
- If any defect is found, contact Bertazzoni North America at 1-866-905-0010 or a licensed plumber to replace the supply hose before returning the dishwasher to service.
When to call a technician
Active dripping, corroded fittings that do not seal when hand-tightened, or a hose with visible cracking or bulging should be replaced immediately by a qualified plumber or Bertazzoni service technician. Do not run additional dishwasher cycles until the supply connection has been confirmed watertight.
