3Disassembly – 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 sidePry outer & inner tabs together L – RPry out (3) inner tabs all outer tabsHINT: The knob does NOT haveto be removed to remove thecontrol module. The module liftsoff completely from the panel,knob & buttons.HINT: Don’t force modules out from fascia panelsto avoid breaking plastic parts. If modules don’tcome out easily, the procedure hasn’t beenfollowed and plastic parts will break.702 58300000133618 ara en aHINT: Don’t remove the wireholders – clip off wire tiesinstead. Carry extra wire ties toreattach wire harnesses.NOTE: Some control modules have beenreplaced since fault codes stored inmodule or motor control can’t be cleared.Modules are operating properly andshouldn’t be replaced to clear fault codes.Rev 0 (1/17/08)

5Disassembly – Tub, Drum & DampersOuter drum (tub)The tub consists of two durable Polinox plastic shellsscrewed to each other.All washers starting with index /04 have new resin tubs, frontand rear, with a translucent beige-tan color compared to olderblue-white tubs. To avoid leaking, tubs must have the sameresin front and rear, whether older blue-white tubs or newbeige-tan tubs – front/rear tub resin types cannot be mixed.To remove outer tub:1.NewDisconnect wire harnesses (as needed) – wire tiescan be cut off, but clips shouldn’t be cut.2.Remove front panel, rear panel, fascia panel (withdetergent dispenser) and top panel.3.Remove door seal, top counterweight and both sidecounterweights.4.Disconnect dampers from tub and slip belt off of tub.5.Remove tub through rear of washer.6.Remove (18) T-25 Torx screws holding front & reartubs together.OldComparingtub resinsNOTE: You can see your fingers through new resin tubsT-25 screwsRemoving front of tubNOTE: Rear drum bearings are factory press fit intorear outer tubs and cannot be removed or serviced.Removingtub screwsHINT: When installing outer tub bolts, screw them in byhand onto the first thread.thread them.Do not overtighten or cross-HINT: Unlike WFL2060 & WFR2460 washers, no clipshold tubs together – no drilling or cutting is needed.702 58300000133618 ara en aDamperRev 0 (1/17/08)

10WFMC Service Tips – Installing Door SealsCertain repairs can involve removing or disconnecting the door seal (gasket) for access. To insure properwasher operation and prevent leaking, door seals must be reinstalled correctly.Make sure clamp doesn’tpull seal off front shieldPlace spring clampover left half ofseal in notchMake sure seal isproperly seated onfront shield flangeCenter notch in bottom ofseal (for spring) underbottom of doorKeep clampspring over notchat seal bottomTo install door seals:1) Align door seal so notch (for spring) at front is centeredunder bottom of door.2) Carefully push rear of seal over front of tub so sealproperly seats onto tub.3) Stretch rear spring clamp over seal and insert intonotch at rear of seal.4) Using small hose clamp, attach dispenser hose to seal.5) Work front seal lip over front shield flange (so lipDispenserhoseInnerspring702 58300000133618 ara en aCarefully pull spring toright & put clamp intoright side seal notch“snaps” in). Tug around entire seal to check if seated.6) Align clamp spring at door bottom, then insert frontspring clamp into notch of entire left half of door seal(180º from top to bottom).7) While pulling right side of spring using needlenosedpliers, pull clamp into right side seal notch, thencarefully release spring. Hold clamp next to frontshield so clamp won’t pull seal off.Hold clampnext tofront shieldNOTE: Check to make sure seal isseated after installation so noleaking will occur.TIP: Left-handed servicers -- startthe front spring clamp on the rightside and pull the spring to the left.Rev 0 (1/17/08)

13WFMC Service Tips – Vibration ChecklistFront loaders can vibrate more than top loaders due to higher spin speeds. Checklist for occasional vibration:Re-level washer – Most vibration service calls come from improperly leveled washers. Re-level washersside to side and front to back using a bubble level. Each leveling leg must contact the floor firmly -adjustments as slight as a ¼ of a turn (in leveling legs) make a difference since each leg must support 25%of the weight.Raise front of washer – Tests have proven raising both front legs of washers by 1/8 – ¼ inch (after levelingwashers) lowers vibration.Retract leveling legs to lower washer as much as possible – When leveling, start with all legs fullyretracted and extend only as necessary for proper level.Tighten leveling leg locknuts – Prevents loosening over time.Remove all four shipping bolts – Shipping bolts or their red plastic spacers have been left in washers.Make sure all four shipping bolts and plastic spacers (that have fallen inside washers) have been removed.Use double-sided tape under leveling legs – Helpful for washers on slick floors.Check dampers – Make sure dampers are working properly and all nuts are tightened.Check springs – Make sure all three springs are properly attached and are free to move.Check bottom (base) panel for damage – Bent bottom (base) panels can cause vibration. Check washersfor shipment damage.Check counterweights – Replace any broken or cracked top and front counterweights. Tighten all bolts.Reinforce floor – Wooden subfloors may need reinforcing. More likely on upper floors.Re-levelwashers!Tub rearspring702 58300000133618 ara en aRaisefront legsDamperTIP:Use a 13mmsocket wrench to removeshipping bolts. Checkfor any red plasticspacers inside washer.Rev 0 (1/17/08)
14WFMC64/84 Service Tips – Sensors1A. Load Sensor (WFMC32/33/53)At a predefined points during the initial fill, the washer determines if it needs more water using a pressure switch. This is dueto differences in the absorption of the laundry and the size of the loads.1B. Dynamic Load Sensor (WFMC64/84)During the entire fill the washer continually adjusts for the size of the load and determines if more water is needed using ananalog pressure switch and a flow meter.2. Digital Temperature Sensor (WFMC32/33/53 & WFMC64/84)The thermostat monitors the temperature of the water and controls the length of time the heating element is on, ensuring theproper temperature for the chosen cycle.3A. Suds Sensor (WFMC32/33/53)During the beginning of the1st rinse/spin phase, the washer determines if there are excessive suds and automatically adds 2rinses (if necessary). This is accomplished via the pressure switch and the motor synchronization system.3B. Continuous Suds Sensor (WFMC64/84)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 (ifnecessary). This is accomplished via the pressure switch, analog pressure switch and the motor synchronization system.4. Unbalanced Load Sensor (WFMC32/33/53 & WFMC64/84)During the final spin cycle the washer monitors the positioning and balance of the load. If the load unbalanced, the washerstops and adjusts the load up to 15 times and reduces the spin speed to finish the cycle. This is accomplished via the motorsynchronization system.702 58300000133618 ara en aRev 0 (1/17/08)
15WFMC64/84 Service Tips – Water Flow MeterFlow sensorThe flow sensor measures the volume of (cold)water flowing into the detergent dispenser.Itconsists of an impeller wheel with a magnet coreand a Hall integrated circuit. When the wheelrotates, the magnet emits impulses to the Hall IC.Water flowColdColdThe water flow is marked by an arrow on the side ofthe sensor.HotSpecifications: Voltage:12 VDC Detected flow rate:0 – 10 liters/minuteNOTE: If there’s air bubbles in the water, higherflow rates may be detected.Water flow arrowHINT: Make sure the water flow arrow pointsfrom the water inlet valve to the dispenser.702 58300000133618 ara en aRev 0 (1/17/08)
16WFMC64/84 Service Tips – Mechanical &Analog Pressure SwitchesThe water level (pressure switch) system consists of apressure sensor and a pressure switch.Pressure SwitchPressureSensorThe pressure switch (brown) has (3) switching positions: Water level level 1Water heating levelOverflow levelPressure SensorPressureSwitchThe pressure sensor (black) determines the different waterlevels in the various wash programs. It is piezo-electric(pressure on it generates a voltage) and generates between0.5 - 3.5 VDC.HINT: Its not helpful to measure the pressure sensor voltagebecause its shown on the digital display while the washer is inthe test program.702 58300000133618 ara en aRev 0 (1/17/08)
