If replacement SHV46/66, SHX33/43/46 or SHY56/66 door
latches/wire harnesses are miswired (with door latch
terminals backwards), dishwashers run with doors open
and lights won’t turn on when doors are open. Control
modules can be irreversibly damaged.
No display – door latch wired incorrectly
Proper display – door latch wired correctly
Rewiring door latches:
• Check wiring to photos below –
the double
wire must be
connected to the silver
door
latch terminal.
• With door open, turn on
dishwasher – keep door open.
If display doesn’t turn on, turn
off dishwasher and reverse
door latch terminal.

CAUTION: Operating dishwashers with miswired door latches will cause
irreversible damage to control modules if doors have been closed and
circulation pumps have started – modules must
be replaced. Check door
latch wiring whenever door latch terminals are changed or disconnected or
when displays don’t light up when dishwashers are turned on.
IMPORTANT: If dishwashers with miswired door latches are corrected
before doors are closed and circulation pumps started, modules can still be
used. If displays don’t light up, turn off dishwashers and reverse door latch
terminals before modules are damaged.
