Bosch WAT28401UC/01 washer Parts

For Bosch model WAT28401UC (a washer), an E01 “dryer” error does not apply; E01/E02 are commonly dryer airflow or lint-filter related. If you are seeing an E01-style message on a Bosch dryer, the practical reset is to clear the cause (lint restriction), then power-cycle the dryer.

Quick reset steps (after fixing the cause)

• Turn the appliance Off.
• Unplug it (or switch the breaker off) for 2 to 5 minutes.
• Clean the lint filter thoroughly; rinse with water if it is coated, then dry it completely.
• Reinstall the filter and make sure it seats fully.
• Restore power and start a short cycle to confirm the code is cleared.

What usually triggers E01 on Bosch dryers

Most E01/E02 dryer errors point to restricted airflow. Check these common items:

• Lint filter clogged or coated with fabric softener residue
• Exhaust vent crushed, kinked, or excessively long
• Vent hood flap stuck closed or blocked by lint
• Excess lint buildup inside the vent pipe
• Overloading, which can reduce airflow through the drum

Most Bosch washing machines last 10 to 15 years with normal household use. For the Bosch WAT28401UC, consistent care (especially keeping the drain system and door seal clean) and correct installation on a solid, level floor help you reach the longer end of that range; see the owner's manual.

Typical lifespan and what changes it

A washer’s life is mostly driven by load size, cycle frequency, and how well water drains and the unit stays balanced during high-speed spin.

• Normal use: 10 to 15 years
• Heavy daily use: closer to 10 years
• Light use with good maintenance: often 12 to 15 years
• Hard water and excess detergent: can shorten life by causing buildup
• Poor leveling or soft flooring: increases vibration and wear

Maintenance that helps you get the full lifespan

These are the highest-impact habits for a front-load Bosch washer like the WAT28401UC.

• Run periodic cleaning cycles (Bosch recommends a Drum Clean cycle before the first load and as needed afterward).
• Clean the drain path regularly; a clogged filter can strain the pump.
• Check pockets to reduce coins, pins, and debris entering the pump.
• Keep the door gasket and detergent area dry between loads to reduce odor and residue.
• Use the right amount of HE detergent; too much can cause oversudsing and buildup.

Parts that commonly affect longevity

If the washer stops draining, leaks, or becomes noisy, these parts are frequent wear or clog points on this model.

Symptom	Common area to check	Example part for WAT28401UC
Won’t drain or drains slowly	Pump and filter	Washer drain pump 00145753, washer drain pump filter 00647920
Leaks during drain	Drain hose connections	Washer drain hose 00656689
Loud thumping or vibration in spin	Suspension and leveling	Leveling and floor support (see manual)

Why it matters

A washer that is level, drains freely, and stays clean runs cooler and smoother. That reduces stress on the motor, inverter, belt, and pump, which are the components that most often determine whether a washer reaches 15 years.

The most common issue we see with Bosch washers like model WAT28401UC is a drain or spin interruption caused by an unbalanced load or restricted draining (often a clogged drain pump filter). These problems typically show up as loud banging, water left in the drum, or a cycle that stops before final spin.

What to check first (fast, no-parts steps)

• Pause the cycle and redistribute the load; mix large and small items to balance the drum.
• Run a Drain/Spin (or Spin) cycle again after rebalancing.
• If water remains in the drum, clean the pump filter and check for debris.
• Confirm the washer is installed on a solid, level floor to reduce vibration during high-speed spin.
• Use HE detergent and avoid overdosing; excess suds can contribute to poor draining and spin issues.

Drain vs. balance symptoms (quick guide)

Symptom	Most likely cause	What usually fixes it
Loud banging during spin	Unbalanced load, leveling issue	Rebalance load; level the washer
Water left in drum	Clogged filter, drain restriction	Clean filter; inspect drain hose
Stops before final spin	Suds, imbalance, slow drain	Reduce detergent; rebalance; clear drain path
Gurgling or slow drain	Partial blockage	Check hose routing; clean filter

Parts that commonly solve drain-related problems

If cleaning and hose checks do not restore normal draining, these model-matched parts are the most common next steps:

• Replace the washer drain pump filter 00647920 if it is damaged, warped, or will not seal after cleaning.
• Inspect the washer drain hose 00656689 for kinks, pinholes, or internal blockage.
• If the pump hums but will not move water (or is noisy and intermittent), the washer drain pump 00145753 is a frequent fix.

Why it matters

A Bosch front-load washer is designed to protect itself during high-speed spin. If the load is off-balance or the unit cannot drain quickly, it may reduce spin speed or stop the spin for safety. Fixing the root cause prevents repeat stoppages, odor from standing water, and unnecessary wear on the drive system.

For model-specific operating and care details (including safety and usage guidance), follow the owner's manual. You can also look up additional parts by model on Sears PartsDirect.
