/ 15 Operation – Sensors (1) 1A. Load Sensor (WFMC32/WFXD52) 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 (WFMC64/WFXD84) 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.
/ 16 Operation – Sensors (2) 1A/1B. Load & Dynamic Load Sensors Mechanical Pressure Switch - (WFMC32/WFXD52 & WFMC64/WFXD84) 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.
/ 17 Operation – Sensors (3) 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.
/ 18 Operation – Sensors (4) 2. Digital Temperature Sensor All models are equipped with an Electric Heater and Temperature Sensor (NTC) to deliver guaranteed wash temperatures. NOTE: Compare with competition washers which only have heaters in top of the line models.

/ 22 Operation – Cleaning Drain Pump Trap Unlike WFK, WFL & WFR washers, WFMC/WFXD 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. 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 WFMC pumps were black.
/ 23 Operation – Preventing Water Collecting in Door Seals Unlike WFK, WFL & WFR washers, WFMC/WFXD washers have tilted tubs and flow through tub paddles to help prevent water collecting in door seals and to enhance wash water flowing through clothes. Paddles direct water toward front of washer – water drains into paddles from outside of inner drum, flows toward front of paddles and exits holes in front of paddles onto clothing in front of washer.
/ 24 Operation – Laundry Deflector Unlike WFK, WFL & WFR washers, WFMC/WFXD washers have a laundry deflector to prevent small items such as socks and wash rags from collecting in door seals. Without laundry deflectors, small clothes items can get jammed in door seals and apply pressure to bottoms of doors. Without the laundry deflector, small clothes items being jammed in door seals would only cause minimal leakage (a few drops).
/ 25 Disassembly – Fascia (Control) Panel (1) T-20 screws To remove fascia panel to access control module & dispenser, remove (4) T-20 Torx front/side screws and lift panel up.

/ 26 Disassembly – Fascia (Control) Panel (2) Control modules can be readily removed from fascia panels, but there’s a knack to it – must use the procedure below exactly as shown. Start from left side Pry outer & inner tabs together L – R Pry out (3) inner tabs + all outer tabs HINT: The knob does NOT have to be removed to remove the control module. The module lifts off completely from the panel, knob & buttons. HINT: Don’t force modules out from fascia panels to avoid breaking plastic parts.
/ 27 Disassembly – Top & Rear Panels (1) T-20 screws Remove top panel screws Remove top panel Top panel removed Rear panel removed To remove rear panel to access drive motor and rear of drum, remove (18) T-20 screws.

/ 55 WFMC/WFXD Service Tips – Resetting Door Locks (1) Occasionally door locks stay locked when doors are opened while they’re locked, preventing doors from closing. Please follow these instructions to reset door locks. Rear view Remove front seal spring Move door seal for access Push onto back of door lock until it clicks open HINT: Reach around back of door lock (opposite latch opening) and push onto back of lock plate (directly behind latch) until it clicks.
/ 56 WFMC/WFXD Service Tips – Resetting Door Locks (2) There are three ways to reset door locks (shown below) – each has advantages & disadvantages: 1. 2. 3. Access past door seal (shown on previous page) – eliminates any chance of cosmetic damage, but requires reattaching door seal spring (which can be tricky). Access from top panel – provides access to door lock without removing door seal, but allows scratching of fascia panel and screw caps.
/ 57 WFMC/WFXD Service Tips – Replacing Door Locks Some door locks on units made on or before 2/13/04 may not hold properly. Replace them (as shown below): 1. Acceptable door locks – Those showing “N” at end of # on end of housing. If # end of housing doesn’t show “N”, then those showing “1” on black housing and “1”, “2” or “3” on white carrier (see below). 2.
/ 58 WFMC64/WFXD84 Service Tips – Water Flow Meter Flow sensor The flow sensor measures the volume of (cold) water flowing into the detergent dispenser.

/ 83 WFMC/WFXD Service Tips – Oversudsing & Suds Lock If washers time out and shut off without an end of cycle signal (and without going through the spin cycle), the washer has experienced suds lock, a possible occurrence with all front loader washers (regardless of manufacturer). • Suds lock: Suds lock comes from suds (airy foam) interfering with water level sensors (pressure switches). Electronic controls are fooled into thinking water hasn’t been removed fully, so washers won’t go into spin cycles.
