To start test program, press and hold both POWER SCRUB PLUS and QUICK 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, REGULAR WASH, QUICK WASH and RINSE & HOLD),
press and hold each program button. When REGULAR WASH program button is pressed, CLEAN light also comes on
and an audible tone (“beep”) also occurs.
To start testing, press both POWER SCRUB PLUS and QUICK 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
REGULAR WASH = Water filling fault (over or under filling)
QUICK 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), REGULAR 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), QUICK 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.
