KWC faucet support can help with warranty claims, replacement parts, model identification, cartridges, spray hoses, finishes, electronic controls and installation questions. KWC’s North American support structure has changed, and the current official distributor is PAINI US rather than Franke Kitchen Systems.
KWC Faucet Customer Service and Warranty Contacts
KWC’s current official North American pages do not publish the former 1-678-334-2121 number or the former Monday-through-Friday support schedule. The PAINI US number above is a distributor-office number; email is the clearest currently published route for a consumer support or warranty inquiry.
Best KWC Support Route by Issue
- Residential faucet warranty: Email KWC support and include the receipt, model, finish, installation date and photographs.
- Recently purchased defective product: Contact the selling dealer first and ask whether the issue falls under its return or exchange policy.
- Replacement cartridge, hose or spray head: Send KWC clear photographs and all identifying numbers.
- Unknown or discontinued model: Photograph the complete faucet, handle, spray head, base, labels and under-sink connections.
- Installation question: Consult the model’s instructions, the authorized dealer or a licensed plumber.
- Active leak: Shut off the water when safe and contact a plumber before waiting for a warranty response.
- Electronic faucet or control: Provide the power-source details, control-box information and error symptoms.
- Commercial or institutional fixture: Verify whether the product belongs to KWC Professional or the DELABIE product organization.
- Order placed with a retailer: Contact that retailer for shipping, cancellation, return and refund questions.

Do not publicly post complete receipts, home addresses, payment information, serial numbers or private support correspondence.
How to Identify a KWC Faucet Model
The exact model is important because similar-looking KWC faucets may use different cartridges, spray heads, hoses, aerators and electronic components.
Check:
- The original receipt or invoice
- The product box
- The installation and service instructions
- Labels attached to supply hoses or under-sink components
- Numbers stamped or printed on the faucet body
- Markings on the cartridge or spray head
- The archived product information available from the dealer
When the model cannot be found, send photographs showing the front, side, handle, spout, pull-out spray, faucet base and under-sink connections. Include approximate purchase and installation years.
KWC Warranty for Products Sold From 2022 Onward
KWC’s current U.S. limited warranty applies to qualifying KWC products sold after January 1, 2022 and installed in the United States or Puerto Rico.
For an eligible original residential purchaser, current coverage generally includes:
- Mechanical parts: Limited lifetime coverage while the original purchaser owns the home
- Product finishes: Limited lifetime coverage while the original purchaser owns the home
- Electronic faucets, valves and controls: Five years from purchase
- Spray heads, cartridges and hoses: Five years from purchase
The warranty applies only to qualifying products purchased from KWC or an authorized KWC seller. KWC may reject a claim involving an unauthorized seller or unauthorized internet site.
Important Current KWC Warranty Exclusions
The current warranty does not cover every leak, failure, finish problem or installation expense.
Exclusions include:
- Commercial installations
- Products transferred or resold by the original purchaser
- Display products
- Normal wear and tear
- Outdoor use
- Improper installation
- Improper maintenance
- Misuse, abuse, negligence or accidents
- Unauthorized alterations
- Abrasive, caustic or no-rinse cleaning products
- Excessive water pressure
- Corrosion or adverse home water conditions
- Filters, coolers and heater parts or accessories
- Products or accessories not manufactured by KWC
Labor, diagnostic charges, disconnection, removal, packaging, shipping, installation and reinstallation expenses are not included in the current limited warranty.
Warranty for KWC Faucets Sold From 2003 Through 2021
Products sold before January 1, 2022 are governed by the warranty in effect for that period rather than the current warranty.
The published 2003–2021 warranty generally provided:
- Limited lifetime coverage for qualifying mechanical faucet parts
- Limited lifetime coverage for chrome finishes
- Five years of coverage for other finishes
- Coverage only for the original owner in a normal residential installation
That warranty also contained separate exclusions involving improper installation, misuse, incorrect cleaning, normal wear, outdoor or marine installation, reverse-osmosis combinations, unauthorized repair, labor and reinstallation expenses.
Provide the purchase date when contacting KWC so the company can apply the correct version of the warranty.
How to File a KWC Warranty Claim
- Locate the receipt, invoice or purchase order.
- Identify the model, product number and finish.
- Record the purchase and installation dates.
- Take clear photographs of the faucet and problem.
- Describe the defect, when it began and whether it is getting worse.
- State whether the product is installed in a private residence.
- Identify the seller or authorized dealer.
- Email the information to KWC-support.us@kwc.com or kwc-service.us@kwc.com.
- Keep the original product and defective parts unless KWC authorizes disposal.
- Save the claim number and all correspondence.
KWC states that it will use commercially reasonable efforts to process warranty claims within seven to fourteen business days. Complicated model-identification, dealer-verification or documentation issues may require additional time.
KWC Dealer Returns Versus Warranty Claims
A retailer return and a manufacturer warranty claim are different processes.
Contact the seller first when:
- The faucet is unopened.
- The wrong model or finish was shipped.
- Parts were missing from a new box.
- The item arrived visibly damaged.
- The order must be cancelled.
- A refund rather than repair or replacement is requested.
Contact KWC for a possible warranty claim when a qualifying installed product has a suspected manufacturing defect.
Do not mail a faucet or component to PAINI US, KWC in Switzerland or an old Franke address without written authorization and shipping instructions.
KWC Replacement Parts
Common replacement-part requests include:
- Cartridges
- Pull-out and pull-down hoses
- Spray heads
- Aerators
- Handle components
- O-rings and seals
- Mounting hardware
- Electronic controls
- Power supplies
- Valves and solenoids
Do not order a part based only on the faucet’s appearance. Confirm the model and part number because visually similar KWC products may not use interchangeable components.
Older parts may be discontinued. Ask KWC whether an approved replacement, updated component or compatible conversion exists before modifying the faucet.
Help With a Leaking KWC Faucet
A leak may come from the cartridge, handle seals, spout, spray hose, spray head, supply connection, electronic valve or another internal component.
When an active leak could damage cabinets, flooring or walls:
- Shut off the hot and cold supply valves when it is safe to do so.
- Use the home’s main water shutoff if the fixture valves do not stop the leak.
- Open the faucet briefly to relieve pressure after the water is shut off.
- Dry the cabinet and protect surrounding property.
- Photograph the source of the leak.
- Contact a licensed plumber for urgent diagnosis or repair.
- Contact KWC separately about possible parts or warranty coverage.
Warranty processing should not delay emergency action needed to prevent water damage.
Cartridge, Handle and Water-Flow Problems
Contact KWC or a qualified plumber when the faucet:
- Drips after being turned off
- Has a stiff or loose handle
- Does not mix hot and cold water correctly
- Produces reduced or uneven flow
- Leaks around the handle
- Will not shut off completely
Mineral buildup, debris, water pressure, seals or a worn cartridge may be involved. Avoid forcing the handle or installing an unverified generic cartridge.
Spray Hose and Pull-Out Faucet Problems
For a damaged spray hose, leaking pull-out connection or spray head that will not switch modes:
- Stop using the pull-out feature if the hose is splitting or leaking.
- Inspect visible connections without disconnecting pressurized plumbing.
- Photograph the hose markings and both end connections.
- Provide the faucet model and approximate age.
- Ask KWC to confirm the correct replacement assembly.
A replacement hose or spray head may have model-specific fittings and should not be assumed compatible based only on length or appearance.
Electronic KWC Faucet Problems
Electronic KWC faucets may include controls, sensors, valves, power supplies or other model-specific components.
Before contacting support, note:
- Whether the faucet has battery or electrical power
- Any lights, signals or error behavior
- Whether water flow is intermittent or completely absent
- Whether the problem began after a power outage or plumbing work
- The control-box and power-supply labels
Turn off water and electrical power when required by the installation instructions before opening an electronic control box. Use a qualified plumber or electrician when the repair involves concealed wiring, line voltage or pressurized plumbing.
Finish and Cleaning Complaints
Keep photographs and cleaning-product information when reporting discoloration, spotting, peeling, corrosion or finish deterioration.
KWC’s current warranty excludes damage associated with abrasive, caustic and no-rinse cleaning products. Follow the cleaning and care instructions supplied with the product and avoid aggressive chemicals or abrasive pads.
Hard-water deposits, household chemicals, corrosion and physical scratches may be treated differently from a manufacturing defect.
Installation and Water-Pressure Concerns
Improper installation and excessive water pressure are excluded from the current warranty.
Before filing a claim, check whether:
- The supply connections are secure.
- The faucet is installed according to its instructions.
- The mounting hardware is correctly assembled.
- The hoses are kinked or twisted.
- Water pressure may be excessive.
- Debris entered the faucet during plumbing work.
- The product is being used outdoors or commercially.
A licensed plumber can document the installation and determine whether the problem is caused by the product, plumbing conditions or installation.
KWC Home and KWC Professional Are Different
KWC Home covers residential kitchen and bathroom faucet products. Its current North American distributor is PAINI US.
KWC Professional historically supplied commercial and institutional products for public washrooms, healthcare facilities, schools, security environments and other specialized settings. That business is transitioning to the DELABIE organization.
