50.(00110010) Phase 2 to 5 - Hot Valve Fault
The Motor Controller has measured a voltage from the valve diagnostic circuit that indicates that the hot valve is faulty. The most likely cause is that the valve harness has not been connected correctly.
Primary Source - Wiring
Action - Check valve harnesses are correctly fastened to valves.
Secondary Source - Water Valves
Action - Check valve coils are not faulty ( open circuit ). If either of these valves are low impedance it is likely that the Motor Control output has also failed, in which case replace Motor Controller and valve(s).
NB. Phase 5 can give fault code 50 when Smartdrive powers off while spinning. In this case there will be no fault.
51.(00110011) Phase 5 ECO – Recirculation Fault
The product has detected that it is losing water during recirculation.
Primary Source – Diverter Valve Wiring
Action - Check diverter valve harness is correctly fastened to diverter valve. Check flying lead in motor controller, and connection to valve next to drain pump.
Secondary Source – Diverter Valve
Action - Check diverter valve resistance. If open circuit (nominal is 1500 ohms) replace diverter valve. During recirculation, check that water is being recirculated back into the bowl, and that no water is coming out of drain hose. If there is some water coming from the drain hose, then the diverter valve could be faulty, or it could be jammed with a foreign object. Replace diverter valve.
Tertiary Source - Motor Controller
Action - The diverter valve drive circuit may be at fault. If the primary and secondary checks pass inspection then replace the Motor Controller.
