Bosch WFMC3301UC/06 washer Parts

On the Bosch WFMC3301UC washer, an E06 pump error points to a drain problem: the washer is not pumping water out fast enough. We fix it by clearing the pump filter and drain path first; if the pump still only hums or won’t move water, the drain pump circuit needs service.

Quick checks that solve most E06 drain errors

• Unplug the washer for 1 minute, then plug it back in and try a Drain/Spin.
• Bail out water if needed, then clean the pump filter (coins, lint, socks are common).
• Check the drain hose for kinks, crushing, or a clog at the standpipe/sink connection.
• Verify the drain hose height and routing match the WFMC3301UC owner’s manual.
• Make sure the washer is not overloaded; heavy loads can slow draining.

Step-by-step: clean the pump filter safely

1. Unplug power.
2. Place towels and a shallow pan under the pump filter area.
3. Open the pump filter slowly to let water drain out in a controlled way.
4. Remove debris from the filter and the pump cavity (feel for small objects).
5. Reinstall the filter fully and snugly; a loose filter can leak and re-trigger drain faults.

What to do if it still won’t drain

If the filter and hose are clear but E06 returns, focus on the drain pump system.

What you observe	Most likely cause	What we recommend
Pump runs but weak/no flow	Partial blockage in hose or pump cavity	Recheck hose routing and pump cavity for debris
Pump hums, no movement	Pump impeller jammed or failed	Pump/motor service by a technician
Drains sometimes, not always	Intermittent obstruction or wiring issue	Inspect wiring connections; schedule service

Why it matters

A drain restriction can leave water in the tub, stop the spin cycle, and strain the pump. Clearing the filter and ensuring proper drain hose setup restores normal draining and helps prevent repeat E06 errors.

The Bosch WFMC3301UC is a compact front-load washer; most units in this Bosch Nexxt-style platform are about 2.2 to 2.5 cu. ft. capacity. For the exact rated capacity for your specific configuration, confirm it in the WFMC3301UC owner’s manual.

How to confirm the exact capacity (fast checks)

• Look in the specifications section of the WFMC3301UC owner’s manual.
• Check the model/rating label on the washer (often inside the door opening or on the cabinet edge).
• If you see multiple similar model numbers, match the full model exactly: WFMC3301UC.
• Use the capacity to choose proper load size; front-loaders clean best when the drum is not packed tight.
• If you are troubleshooting fill or temperature issues, verify your inlet setup and hoses.

Typical capacity ranges (what you should expect)

Washer type	Typical capacity range	Common use case
Compact 24-inch front-load (like WFMC3301UC)	2.2 to 2.5 cu. ft.	Apartments, smaller loads
Full-size 27-inch front-load	4.0 to 5.5 cu. ft.	Larger families, bulky items

Why it matters

Capacity affects how much laundry you can wash per cycle, how well items tumble for cleaning, and how much detergent you should use. Overloading a front-load washer can lead to poor cleaning, excess vibration, and longer cycle times.

Related parts that affect performance (not capacity)

If you are asking because loads seem too wet, too soapy, or cycles seem off, these parts can be involved:

• Washer cold water inlet valve 00422244 (controls cold water fill)
• Washer hot water inlet hose 00422245 (supplies hot water to the washer)
• Washer damper 00642112 (helps control tub movement during spin)

A Bosch washing machine typically lasts 10 to 15 years with normal household use and basic upkeep. For your Bosch WFMC3301UC washer, consistent maintenance, correct detergent use, and fixing small leaks or vibration early are what most often determine whether you reach the longer end of that range. See the WFMC3301UC owner’s manual for model-specific care and operating guidance.

Typical lifespan and what affects it

Most front-load washers like the Bosch WFMC3301UC land in the 10 to 15 year window. These factors have the biggest impact:

• Load size and frequency (daily heavy loads shorten life)
• Proper installation and leveling (reduces bearing and suspension wear)
• Detergent type and amount (too much can cause residue and odor)
• Moisture control (leaving the door ajar helps prevent mold and gasket issues)
• Water quality (hard water can increase scale and valve wear)

Maintenance checklist that extends service life

Use this routine to reduce common front-load washer failures:

• Wipe the door boot and glass dry after laundry day
• Run a monthly cleaning cycle (washer cleaner or hot cycle as recommended)
• Check fill hoses for bulges, cracking, or seepage; replace if needed
• Keep the washer level and stable to prevent excessive vibration
• Clean the detergent drawer area to prevent buildup

Quick “repair or replace” guide

What you notice	Most common cause	What we recommend
Water leaking at the door	Worn or dirty door boot	Clean and inspect; replace the boot gasket 00667489 if torn or deformed
Loud banging or walking during spin	Leveling issue or worn dampers	Re-level; inspect suspension and consider the washer damper 00642112
Slow fill or fill errors	Inlet valve or supply issue	Check screens and pressure; consider the washer cold water inlet valve 00422244

Why it matters

A washer that is kept clean, dry between uses, and properly leveled runs with less strain on the tub, bearings, and control system. That directly improves reliability and helps you avoid repeat repairs.
