Washer overfills or won't stop filling

One quick test splits the job in two: kill power while it is overfilling. If water keeps coming with no power, the inlet valve is stuck open mechanically. If water stops, the valve is being told to stay open, so look at level sensing (pressure hose, air dome, level switch/sensor) and then the control. Siphoning (water leaving through the drain while filling) can look like a washer that never stops filling.

Whirlpool family washers & dryers: reading F#E# codes, Service Diagnostic Mode and fault history

Whirlpool-family electronic laundry stores its last few faults as a pair: the F number names the system and the E number names the suspect part. Most knob-and-button consoles reach Service Diagnostic Mode by pressing three buttons in a set order three times in a row within a few seconds; newer touch consoles use a different entry. The exact buttons are on the tech sheet hidden in the console, so read it first and never guess.

Samsung washers & dryers: display codes vs information codes, SmartThings and Smart Care, and service-mode code history

Samsung splits codes into information codes (a user or installation condition such as swapped hot and cold hoses or an unlatched door) and real error codes. The same fault may read differently by generation: older machines used E-numbers or 4E-style codes, newer ones 4C-style, some top-loaders nF. Wi-Fi models push codes to SmartThings when they happen; Smart Care is a separate camera-based check that only reads its own test, not real codes. Many models also keep a stored-code list in a service mode whose buttons vary by model.

Washer routine service: tub-clean cycle, door boot, dispenser, pump filter and hoses (front and top load)

All the major brands build in a cleaning cycle and remind the user about once a month or every 20-40 loads: Whirlpool about every 30 cycles, LG after about 30 cycles ('tcL'), Samsung after 40 washes on front-loaders and 20 on top-loaders. A pro service adds what the cycle misses: the door boot, dispenser, drain pump filter on front-loaders and a hose inspection.
