Disassembly

––Fascia (Control) Panel (2)

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

HINT: Don’t force modules out from fascia panels

to avoid breaking plastic parts. If modules don’t come out easily, the procedure hasn’t been followed and plastic parts will break.

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 remove the wire

holders – clip off wire ties instead. Carry extra wire ties to reattach wire harnesses.

NOTE: Some control modules have been replaced since fault codes stored in module or motor control can’t be cleared. Modules are operating properly and shouldn’t

be replaced to clear fault codes.

Comparing

tub resins

All washers starting with index __/04 have new resin tubs, front and rear, with a translucent beige-tan color compared to older blue-white tubs. To avoid leaking, tubs must

have the same resin front and rear, whether older blue-white tubs or new beige-tan tubs – front/rear tub resin types cannot be mixed

NOTE: You can see your fingers through new resin tubs
