Bosch Washers 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 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 or ten business days after delivery date, whichever comes first.
1 Year Full Limited Warranty
Bosch will repair or replace, free of charge, any component part that proves defective
under conditions of normal home use, labor and shipping costs included. Warranty
repair service must be performed by an authorized Bosch Service Center.
2 Year Limited Warranty
Bosch will provide replacement parts, free of charge, for any component part that
proves defective under conditions of normal home use, shipping costs included, labor
charges excluded.

Factory serial # - Can convert
factory serial # to FD # for
warranty use. 1st 2 digits show
factory # (85 = New Bern), 3rd digit
shows year (1 = 2003), 4th & 5th
digits show month built (08 =
August). So, serial # starting with
“85308…400126” = washer built
@ New Bern with FD 8308
000126.
•Model # - “WFMC6400UC/01”.
•Serial # - “FD 8308”. To find when the product type
was built, add 20 to the 1st two digits to get the year
(83 + 20 = 103 product type was built in 2003). The
last two digits show the month (08 = August).

1A. Load Sensor (WFMC3200UC)
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 (WFMC6400UC)
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. Digital Temperature Sensor (WFMC3200UC & WFMC6400UC)
The thermostat monitors the temperature of the water and controls the length of time the heating element is on, ensuring the
proper temperature for the chosen cycle.
3A. Suds Sensor (WFMC3200UC)
During the beginning of the1st rinse/spin phase, the washer determines if there are excessive suds and automatically adds 2
rinses (if necessary). This is accomplished via the pressure switch and the motor synchronization system.
3B. Continuous Suds Sensor (WFMC6400UC)
Checking the pumping out phase of the main wash, the beginning of the 1st rinse/spin phase and the actual spin speed vs.
the programmed spin speed, the washer determines if there are excessive suds and automatically adds up to 2 rinses (if
necessary). This is accomplished via the pressure switch, analog pressure switch and the motor synchronization system.
4. Unbalanced Load Sensor (WFMC3200UC & WFMC6400UC)
During the final spin cycle the washer monitors the positioning and balance of the load. If the load unbalanced, the washer
stops and adjusts the load up to 15 times and reduces the spin speed to finish the cycle. This is accomplished via the motor
synchronization system.

1st Edition/Revision 6 (2/2/04)
Mechanical Pressure Switch -(WFMC3200UC & WFMC6400 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.
Analog Pressure Switch -(WFMC6400UC)
• Precise measuring of actual water level
• Accurate load detection
• Control of the pump - noise reduction
• Time reduction - no pumping when empty
BENEFITS: Continuous adjustment of wash times
Water and energy consumed varies according to load size

1A/1B. Flow Meter
Exact monitoring of water inflow.
Ensures exact control of water inlet valves so that there is always the right amount of water for wash and
rinse cycles.
Together with the pressure switch, there is a continuous adjustment of wash time, water and energy in
relation to the load size.
The flow meter works independently of water pressure.
BENEFITS: Minimizes water consumption
Exact Load Detection
Superior Cleaning Performance
•An internal water clock monitors water inflow via soak compartment.
•Ensures exact control of water inlet valves - always right amount of water.
•Independent from water pressure.

Both models are equipped with an Electric Heater and Temperature Sensor (NTC)
to deliver guaranteed wash temperatures.

washers which only have heaters in top
of the line models.

•Accurate measuring of unbalance by deviation of spin speed and slow down
time of drum
•Infinite adapting of spin speeds
•Compensates reducing of spin speeds by prolonging spinning times
•Will attempt up to 15 times to redistribute a load
Advantages:
•Reduction of noise
•Better stability of machine

Unlike WFK, WFL & WFR washers,
drain pumps are maintenance-free.
So, larger objects such as coins
and paper clips are no longer
collected in the drain pump trap.
The drain pump trap is only meant
to be cleared by servicers.
NOTE:There’s no provision to drain
water manually from drain pumps like
earlier models.
HINT: To remove the drain pump
access cover, insert a pointed object
(or tool) into the hole, push in to
release the latch and rotate the cover
clockwise.
Current production pumps are beige
color – earlier pumps were black.
