Bosch SHE43M05UC/48 dishwasher Parts

On a Bosch dishwasher like model SHE43M05UC, we do not recommend running cycles with an E22 error because it commonly points to a drainage or filter restriction; continuing to run it can leave dirty water in the sump and lead to poor cleaning and repeat shutdowns.

What E22 usually means on a Bosch dishwasher

E22 is most often tied to water not moving through the filtration and drain path the way it should.

Common causes to check first:

• Food debris clogging the filter area in the sump
• A blocked drain path (hose, air gap, or disposer connection)
• A weak or jammed drain pump
• Standing water that keeps re-circulating through the filter

For model-specific operating and care steps, use the SHE43M05UC owner’s manual.

What to do before you run another cycle

Start with the simplest checks that fix most E22 situations.

• Cancel the cycle and let the unit drain (if it will)
• Remove and clean the sump filter area (rinse under hot water, scrub grease film)
• Check the sink drain/disposer connection for a plug or blockage
• Inspect the drain hose for kinks, crushing, or a low loop problem
• If the dishwasher will not drain, test/replace the drain pump 00642239

Quick decision guide

What you see	Best next step	Why
E22 and water standing in the bottom	Clean filter and check drain path	Most common restriction point
E22 returns right after cleaning	Inspect hose and sink connection	Hidden blockage is common
Humming but no draining	Consider drain pump issue	Pump may be jammed or weak

Why it matters

A dishwasher depends on steady water circulation and draining for cleaning and drying performance. Clearing the filter and drain path protects the pump system, prevents dirty water from re-depositing soil, and reduces repeat error interruptions.

For code lookups and what to check next, use Bosch dishwasher error codes.

The most common issues we see with Bosch dishwashers like model SHE43M05UC are performance problems that look like a “breakdown” but are usually caused by restricted water flow or drainage: clogged filters, blocked spray arms, or a drain path blockage. Start with the troubleshooting steps in the SHE43M05UC owner’s manual.

Most common symptoms and what they usually mean

• Not cleaning well: filter/sump restriction, spray arm holes clogged, or poor loading
• Not draining: food debris in the sump area, kinked/blocked drain hose, or a weak drain pump
• Not drying: rinse aid empty (Bosch drying improves with rinse aid and airflow)
• Won’t start: door not fully shut and latched, or power supply issue
• Runs a long time: cycle selection, incoming water temperature, or heating-related delays

Quick checks we recommend first (fast, no parts)

1. Confirm the door is fully shut and latched (the manual calls this out as a common no-start cause).
2. Check rinse aid level if drying is poor; the manual notes drying improves when rinse aid is used.
3. Clean the filter area and remove any visible debris.
4. Inspect spray arms for blocked jets and make sure they spin freely.
5. Verify the drain path: look for kinks and clogs in the drain line.

If you want a guided walkthrough by symptom, use Bosch dishwasher error codes to match what you see on the display to the most likely cause.

Parts that commonly solve “cleaning” or “draining” complaints

When cleaning and inspection do not restore normal operation, these parts are frequent fixes on many Bosch dishwashers:

Symptom	Common part involved	Example from this model’s parts
Not draining / water left in tub	Drain pump or drain hose restriction	Drain pump 00642239, drain hose (routing/clogs)
Poor wash pressure / weak spray	Recirculation pump or sealing issue	recirculation pump assembly, pump gasket
Not filling / low water entering	Water inlet valve	Dishwasher water inlet valve 00607335

Why it matters

Bosch dishwashers are designed for efficient water use, so even a partial clog in the filter, spray arm, or drain path can cause noticeable drops in cleaning, draining, and drying performance.

A Bosch dishwasher like model SHE43M05UC typically lasts 10 years with normal household use and basic maintenance. Keeping filters clean, using the right detergent, and fixing small leaks early helps you reach that lifespan.

What affects lifespan most

• Hard water buildup (scale) on the heating and wash system
• Clogged filters or spray arms that reduce cleaning and strain the pump
• Leaks at the door seal or sump area that cause corrosion and motor issues
• Frequent heavy loads and high-heat cycles
• Poor draining that leaves dirty water in the sump

Maintenance that extends life

Use the care and cleaning steps in the owner's manual. In general, we recommend:

• Clean the sump filter regularly; remove debris and rinse it thoroughly
• Check the spray arm holes for blockage and clear them as needed
• Run a dishwasher cleaner cycle periodically (especially with hard water)
• Inspect the door seal for tears, flattening, or gaps; replace if it seeps
• Confirm the drain path is clear (air gap or high loop, hose not kinked)

Common “end-of-life” symptoms and likely causes

Symptom	What it often points to	Example part on this model page
Won’t drain or drains slowly	Drain pump or drain restriction	Drain pump 00642239
Poor washing, weak spray	Recirculation pump issue or clogged filter	Dishwasher recirculation pump assembly 00442548
Water leaking at the door	Worn or mis-seated seal	Door seal 00432490

Why it matters

Dishwashers usually fail from a few high-wear systems (drain, wash circulation, and sealing). Catching those issues early often prevents secondary damage to the motor, bearings, and base.
