Guide · WasherHot and cold water reversed (HC, F0E4, 4C2)
The hoses are swapped at the faucet or at the washer. Swap them; no parts needed.
Guide · WasherReading stored codes and service/test mode (overview)
Entry sequences differ by model and generation. Always confirm on the tech sheet inside the cabinet; the sequences below are examples reported for specific model families.
Guide · WasherSamsung top-load banging / unbalance (suspension rods)
Worn suspension rods let the tub hit the cabinet. After ruling out load and leveling, replace all four rods as a model-matched set.
Guide · WasherTop-load not agitating (fills and drains OK)
On older Whirlpool/Kenmore direct-drive top-loads, fill-and-drain-OK but no agitate/spin is the classic broken motor coupler. On newer models, look at the shift actuator/clutch, lid lock and motor.
Guide · WasherWasher-dryer combo washes but does not dry
Combos are ventless and dry slowly. Clean the condenser/lint path, check load size and power (many need 240 V), then check heater or heat pump.
