POWER SCRUB PLUS
SCRUB WASH

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 (f 1 ) 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 (e 5 ) has failed (opened), water won't heat (to 150
circulating. If NTC probe (f 2 / f 4 ) has failed (opened), REGULAR WASH light will come on immediately and testing will
end shortly after water has started circulating. NOTE: TO ENABLE LIGHTS TO COME ON, DOOR MUST BE OPENED.
If more than one fault occurs, more than one light will be lit.
