Modules Displaying “1”
Modules Displaying “1”
Occasionally dishwashers will run for hours, not finish washing & show a “
1
”
in the display. This means the module has timed out due to an unidentified
heating problem --
all
heating related parts must be checked until the
problem is found.
IMPORTANT:
Whenever a “1” shows in the
module display, the module must be reset (after the
heating problem has been fixed) by running the
dishwasher. The module resets after the 1
st
run.
