Bosch 300 Series WAT28400 front-load washer troubleshooting

Published specification

What is true of this model and changes how you fix it

• Hardware — Bosch product page
  300 series, 2.2 cu ft, 1,400 RPM, 15 cycles, 54 dBA, EcoSilence motor, SpeedPerfect (up to 40% faster wash), ActiveWater Technology, no Home Connect Wi-Fi at this tier.
• Type — COMPACT 24-inch FRONT-LOAD
  A COMPACT 24-inch FRONT-LOAD washer (~2.2 cu. ft.), smaller than a standard 27-inch, made for apartments and to stack with a compact Bosch dryer. Its small drum means small loads — overloading is the usual cause of poor cleaning, unbalance and long cycles.
• AquaStop leak protection
  AquaStop is a multi-part leak-protection system on the hose and base; if it trips (often shown by a water/tap indicator or a base full of water), it has detected a leak and shut off the water — the fix is to find the leak, not to override AquaStop. It is a safety feature doing its job.
• Quiet & sensing
  Bosch compacts are very quiet with a brushless motor; ActiveWater load sensing sets the water automatically, so a low water level is normal. A SuperQuick 15 cycle handles small loads fast.
• Transport bolts
  They must be removed before the first use. Four plastic covers seal the bolt holes afterward, and leaving the bolts in is a classic cause of violent shaking.
• Leveling
  Place it on a solid, level floor with all four feet pressing equally, or it will vibrate.
• Under-counter fit
  It can go under a counter if the ventilation opening is at least 63 sq in.
• Spin
  High spin speeds pull out more water and shorten the dryer time.
