Warranty (1) Bosch Washers and Dryers Limited Lifetime Warranty Statement of Limited Warranty The warranties provided by BSH Home Appliances ("Bosch") in this Statement of Warranties apply only to Bosch clothes washers and dryers sold to the first using purchaser by Bosch or its authorized dealers, retailers or service centers in the United States or Canada. The Warranties provided herein are not transferable, and take place from date of installation.
Warranty (2) 5 Year Limited Warranty On Electronics Bosch will repair or replace, free of charge, any microprocessor or printed circuit board that proves defective under conditions of normal home use for a period of five years from the date of original installation, labor charges excluded.
Warranty -- Serial # Label The serial # label, located on the rear of the washer, shows necessary warranty information. 6 Serial # label 6 • Model # - “WFR2460UC/01”. • Serial # - “FD 8108”. To find when the product type was built, add 20 to the 1st two digits to get the year (81 + 20 = 101 Æ product type was built in 2001). The last two digits show the month (08 = August). Factory serial # - Can convert factory serial # to FD # for warranty use.
Installation -- Reprint of Installation Instructions (“utility knife”) Flat (blade) screwdriver. Be sure to follow all national & local codes. NOTE: “Mains” is the European term for “power”, so “mains cable” = “power cord”. HINT: HINT: Cold & hot water connections are clearly marked on the rear of the washers.
Installation -- Reprint of Installation Instructions ; L L HINT: To avoid damaging washer, don’t move it while the feet (leveling legs) are extended.
Installation -- Reprint of Installation Instructions , Loosen transport (shipping) bolts just enough to remove them from the washer -don’t unscrew them completely so the bushings fall from the bolts into the washer frame. HINT: HINT: Be sure to remove the transport (shipping) bolts & keep them near the washer (for future shipment). HINT: To eliminate possibility of leaking, don’t overtighten fittings. Teflon tape can also be used on all threads.
Installation -- Reprint of Installation Instructions HINT: The washer uses a NEMA 6-15P 240V, 15A, 3wire plug, which mates to a NEMA 6-15R outlet (receptacle). HINT: Bosch dryers include a NEMA 6-15R outlet which the washer NEMA 6-15P 240V, 15A, 3-wire plug can be plugged into. HINT: “Mains” is the European term for “power”, so “mains cable” = “power cord”.
Installation -- Reprint of Installation Instructions Be sure to remove the transport (shipping) bolts! HINT: When moving an existing washer, screw in the feet (leveling legs) first so they won’t be damaged. HINT: Bosch dryers include a NEMA 6-15R outlet which the washer NEMA 6-15P 240V, 15A, 3-wire plug can be plugged into. HINT: “Earth” is the European term for “ground”, so “earth leakage” = “ground fault” (GFCI or GFI receptacle).
Operation -- Fascia Panels WFL 2060UC WFR 2460UC 1st Edition/Revision 5 (1/20/04)
Operation -- Controls WFL 2060UC Both have Regular/Cotton, Permanent Press, Delicates, Hand Washables, Temperature Boost & Power Temperature Boost settings.
Operation -- Sensors (1) 1A. Load Sensor (WFL2060UC) At a predefined points during the initial fill, the washer determines if it needs more water using a pressure switch. This is due to differences in the absorption of the laundry and the size of the loads. 1B. Dynamic Load Sensor (WFR2460UC) During the entire fill the washer continually adjusts for the size of the load and determines if more water is needed using an analog pressure switch and a flow meter. 2.
Operation -- Sensors (2) 1A/1B. Load & Dynamic Load Sensors Mechanical Pressure Switch - (WFL 2060UC & WFR 2460 UC) measures the water level after the first fill. If the water level is high (like for smaller loads), the pressure increases and the pressure switch does not provide more water.
Operation -- Sensors (3) 1A/1B. Flow Meter ¾ Exact monitoring of water inflow. ¾ Ensures exact control of water inlet valves so that there is always the right amount of water for wash and rinse cycles. ¾ Together with the pressure switch, there is a continuous adjustment of wash time, water and energy in relation to the load size. ¾ The flow meter works independently of water pressure.
Operation -- Sensors (4) 1A/1B. Flow Meter Water Propeller emits signals (independent from water pressure) 9 An internal water clock monitors water inflow via soak compartment. 9 Ensures exact control of water inlet valves - always right amount of water. 9 Independent from water pressure.

Operation -- Cleaning Drain Pump Trap Larger objects such as coins and paper clips are collected in the drain pump trap so they won’t plug up or damage other parts of the washer. The drain pump trap can easily be cleaned by customers.
Operation -- WFR 2460UC Sales Demo Mode CAUTION: To avoid danger of electrical shock, make sure the washer is unplugged before changing any electrical connections! IMPORTANT: When reselling any WFL2060 or WFR2460 washers from display floors, replace the white (or gray) drain pump connector so washers will run properly and replace the shipping bolts so washers won’t be damaged during shipment.
Disassembly -- Top & Rear Panels (1) NOTE: Washers have 2 concrete counterweights (top & front) to dampen vibrations. NOTE: When removing top panel, don’t damage white plastic top panel latches. To remove top panel to access control module, dispenser, inlet valves, pressure switch(es), drain reservoir, surge protector & wiring, remove (2) rear screws, then carefully slide panel toward rear of washer (until panel stops) and lift panel up.
Disassembly -- Top & Rear Panels (2) To remove rear panel to access drive motor and rear of drum, remove (7) T-20 & (4) T-30 Torx screws and gently lift panel up (off of tabs at top of panel).
Disassembly -- Drum (1), Top Panel To access the drum, the front panel must be removed first. 1 TO REMOVE FRONT PANEL (to access drum): • c Remove top panel. • d To remove fascia panel, first remove T-10 Torx screw on right endcap and T-20 Torx screws on either side of fascia panel. Remove dispenser drawer (after pushing blue tab) and then remove (3) screws located behind dispenser drawer. Gently pull the bottom of the fascia panel away from the washer.
Disassembly -- Drum (2), Front Panel TO REMOVE FRONT PANEL (continued): • f Carefully loosen door seal clamping rings (outer/inner), taking care not to tear seal. Loosen clamp and disconnect water fill tube from seal, then remove seal. 4 4 • g Remove two T-20 Torx front panel screws from bottom of front panel. • h To remove front panel, carefully pull bottom of panel out away from washer. • i Disconnect door latch connector.
Disassembly -- Drum (3), Outer Drum (Tub) & Dampers HINT: “Jacket” weight is the concrete counterweight on the top of the outer drum. 13.
Disassembly -- Drum (4), Outer Drum (Tub) HINT: After removing crossbar screws, remove crossbars by rotating bottom of them out from washer. HINT: Before disconnecting wire harnesses from control module, mark each one to insure proper reassembly (as several connectors look identical). HINT: To access wire harness connectors to disassemble them, separate control module from fascia panel by carefully prying back plastic clips around the module.
Disassembly -- Drum (5), Outer Drum (Tub) HINT: When installing outer drum bolts, screw them in by hand onto the first thread. Do not overtighten or cross-thread them. NOTE: WFL 2060 drums use a separate gasket with bolts kit # 265964. WFR 2460 drums have the gasket and bolts included with front drum # 238410 (where the gasket and bolts aren’t provided separately). HINT: WFL 2060 & WFR 2460 outer drums (“tubs”) are made by different vendors and can’t be interchanged.
Disassembly -- Drum (6), Rear Bearing HINT: When installing rear bearings for WFR 2460 models, replace the front outer drum with gasket and bolts as well. When installing outer drum bolts, screw them in by hand onto the first thread. Do not overtighten or cross-thread them.
