A 6551 HI owner reports a water intake fault that was not resolved after several service visits (side board, motor, and cable replaced), and paid ₺650 in service fees.
What to check. Water-intake faults on the 6551 HI have proven hard to resolve, with multiple part replacements (motor, cable) not fixing it and a ₺650 service fee; expect possible repeat visits if this symptom appears.

Multiple 6551-series owners report the baskets rusting and going black; the service response is a full basket replacement quoted at 4-5 thousand TL.
What to check. Basket rust is a recurring, expensive failure on the 6551 series: replacement is quoted at 4-5k TL, so factor that into a used-unit purchase or a repair decision.

A 6551 owner reports the machine randomly switching off and restarting mid-cycle every wash; a related 6155 complaint in the same thread points to a faulty main board (ana kart).
What to check. Random mid-cycle power off/on on the 6551 series points to the control board; a sibling-model complaint in the same thread links the same symptom to a faulty main board that was replaced without curing it.

A 6551 owner reports dishes coming out greasy and pots/tava never getting clean despite four service calls; the service attributed it to loading rather than a fault.
What to check. If a 6551 leaves dishes greasy and fails on pots, the service may blame loading; verify spray-arm function and loading before accepting a 'no fault' verdict, since this owner saw no improvement after four visits.

Owner reports the upper spray arm (üst pervane) stops turning and upper-rack dishes come out dirty; a service visit replaced the water pipe to the upper spray arm but the fault persisted.
What to check. If upper-rack dishes come out dirty on a 6551 HI, check the upper spray arm and its feed pipe before assuming a wash-program fault; a single pipe replacement did not fix this owner's unit.
