Fisher & Paykel Dishwasher Water Supply Hose — Safety Notices safety notice from the Fisher & Paykel repair guide.
The water supply hose connecting your Fisher & Paykel dishwasher to the household water line is a common source of slow leaks and sudden floods. Rubber hoses degrade over time, and a hose failure behind the dishwasher can go unnoticed until significant water damage has occurred. Annual inspection is strongly recommended.
Why It Matters
Dishwasher supply hose failures are among the top causes of non-weather-related home flooding. A burst hose can discharge several gallons per minute, damaging cabinetry, flooring, and subfloor structures before the leak is discovered. Fisher & Paykel recommends replacing hoses every five to seven years regardless of visible condition.
What to Check
- Pull the dishwasher partially forward and inspect the hose for cracks, kinks, bulges, or discoloration.
- Check both hose-end fittings for mineral deposits or corrosion that could indicate a slow drip.
- Feel along the hose length for soft spots, which indicate internal rubber delamination.
- Confirm the hose clamps at both ends are tight and free of rust.
- Consider upgrading to a braided stainless-steel hose with an integrated flood-stop valve.
When to Call a Pro
If you find any cracking, bulging, or corrosion, do not continue using the dishwasher until the hose is replaced. Contact a licensed plumber or Fisher & Paykel authorized technician for replacement.
