Check wiring between the main control board and motor control board. If wiring is good, replace the motor control board. 1. Are the hot and cold water hoses switched? Yes, switch the hoses to correct position No, go to step 2 2. Is the HOT water about the same temperature as the cold? Yes, fix the HOT water in the house supply. 1. Check wiring between main board and pump. If OK, then go to step (2). 2. Check wiring between main control and recirculation board. If OK, then go to step (3). 3. Check pump for open coil (resistance check). If OK, then replace main control. 1. Check power in for voltage under load. Correct supply or branch circuit issues. No problem go to step 2. 2. Check power wiring to main board. Yes, fix wiring or plug to main board. No, go to step 3. 3. Check wiring to motor board for short to power or ground. Yes, fix problem. No, replace the main board. Check wiring to main board. Unplug the unit for 1 minute and retry. If problem is not corrected replace main control. Unplug and re-seat connector between UI boards. If problem persists, replace UI satellite board. Check wiring to recirculation pump If wiring is bad, correct wiring problem. If wiring is good, replace recirculation pump. If the problem is not corrected, replace the main control board. Check wiring to concentrated wash pump If wiring is bad, correct wiring problem. If wiring is good, replace concentrated wash pump. If the problem is not corrected, replace the main control board. 1. Is the incoming hot water supply on? Yes, go to step (2). No, turn ON incoming hot water supply at wall. 2. Does there appear to be an issue with the wiring harness from main board to flow meter? No, replace main board and go to step (3). Yes, Perform continuity testing on J12 connector from main board and Flow Meter harness: Pin-6 to Pin-3, Pin-7 to Pin-2, Pin-8 to Pin-1. If issues continue, replace main board and continue to step (3). 3. Is the issue is still present? Test 24 1. Does water enter the washer continuously? 2. Remove power from washer. Does the water stop coming in? 3. Replace the valve assembly. Did this correct the problem? Yes, replace flow meter/valve housing. Yes, got to step (2). No, check air trap for clog, if not, replace the main control board. No, replace water valve assembly. Yes, Check wiring to valve assembly for shorts. If wiring is good, replace the main control board. Yes, problem solved.
