To start test program, press and hold both POWER SCRUB PLUS and REGULAR WASH program buttons, then turn unit
on by pressing ON/OFF button. When program buttons are released, lights above them will flash. To end test program,
press ON/OFF button.
To check program indicator lights (POWER SCRUB PLUS, SCRUB WASH, REGULAR WASH and RINSE & HOLD),
press and hold each program button. When SCRUB WASH program button is pressed, CLEAN light also comes on.
To start testing, press both POWER SCRUB PLUS and REGULAR WASH buttons a second time. When testing has
ended and a fault was detected, the following indicator lights will be lit:
POWER SCRUB PLUS = Heater fault
SCRUB WASH = Water filling fault (over or under filling)
REGULAR WASH
= NTC (temperature sensor) fault – note circulation motor stops shortly after it started
during an NTC fault
To check for heater, high limit or flow switch problems, start testing until heating starts. Using a meter with a current coil,
measure current going into dishwasher. If current is ~ 11 A, then heater, high limit and flow switch are OK. If current stays
at ~ 1.5-2 A, then heater, high limit or flow switch are faulty.
If water level switch (f1) has failed (opened), SCRUB WASH light will come on and unit will continually fill and drain where
testing won't be completed. If flow switch (e5) has failed (opened), water won't heat (to 150
º
F) and water won’t stop
circulating. If NTC probe (f2/f4) has failed (opened), REGULAR WASH light will come on immediately and testing will
end shortly after water has started circulating.
If more than one fault occurs, more than one light will be lit.
