Bosch SHE43RF6UC/64 dishwasher Parts

We don’t recommend running your Bosch dishwasher model SHE43RF6UC with an E22 error because it typically points to a drainage or filter restriction; continuing to run cycles can leave dirty water in the tub and strain the drain system. Clear the cause first, then test a short cycle.

What E22 usually means on a Bosch dishwasher

E22 commonly shows up when the dishwasher senses poor draining or restricted water flow through the filter area.

Check these first:

• Clean the filter assembly and sump area (remove debris, labels, glass)
• Make sure the drain hose is not kinked or crushed behind the unit
• Verify the drain hose routing has a high loop; the hose should rise at least 20 inches above the cabinet floor to help prevent drain problems
• Confirm the sink drain or garbage disposer inlet is not clogged
• If the dishwasher hums but won’t drain, suspect a failing drain pump

Quick decision guide: should I run it?

What you see	What it usually indicates	What we recommend
E22 appears mid-cycle and water remains	Restricted filter or drain path	Stop, clean filters, check hose routing
E22 appears and you hear a drain motor hum	Pump jam or weak pump	Inspect for blockage; consider pump replacement
E22 appears after installation or moving the unit	Drain hose routing issue	Re-route hose to proper high loop

Parts that commonly fix E22 symptoms

If cleaning and hose checks don’t solve it, these model-matched parts are common next steps:

• Dishwasher drain pump 00642239
• Dishwasher drain hose 00668108
• Dishwasher fine filter 00441905

Why it matters

E22 is the dishwasher telling you it cannot move water out as expected. Fixing the restriction protects the drain pump, prevents standing water and odors, and restores normal wash performance.

Yes. We sell replacement parts for the Bosch SHE43RF6UC dishwasher, including common repair items like the water inlet valve, drain pump, circulation pump, door seals, and drain hoses. Use the SHE43RF6UC installation guide and SHE43RF6UC owner’s manual to confirm the correct part and safe service steps.

Common dishwasher parts you can replace

These are some of the most frequently replaced parts for this Bosch dishwasher:

• Dishwasher water inlet valve 00622058 (fills the tub with water)
• Dishwasher drain pump 00642239 (pumps water out at the end of the cycle)
• Dishwasher circulation pump 00442548 (drives wash water through the spray arms)
• Dishwasher door seal, lower 00432490 (helps prevent leaks at the bottom of the door)
• Dishwasher drain hose 00668108 (routes drain water to the sink drain or disposer)

How we recommend choosing the right part

Use this quick checklist before ordering:

• Match the model: Bosch SHE43RF6UC
• Compare the part ID and part name to the failed component
• Check symptoms (not draining, not filling, leaking, not cleaning) to narrow the likely part
• Review access steps and safety notes in the manual before disassembly
• If you are replacing a dishwasher, plan to replace connection items as needed

Quick symptom-to-part guide

Symptom	Most likely area	Example part for this model
Not filling	Water supply and fill system	Dishwasher water inlet valve (00622058)
Not draining	Drain path and pump	Dishwasher drain pump (00642239)
Poor cleaning	Wash circulation	Dishwasher circulation pump (00442548)
Leaking at bottom of door	Door sealing	Dishwasher door seal, lower (00432490)

Why it matters

Ordering the correct dishwasher repair part saves time and prevents repeat problems. For example, Bosch installation guidance calls for routing the drain hose with a high loop (at least 20 inches above the cabinet floor) to help the dishwasher drain properly; a worn hose or incorrect routing can look like a pump failure.

Yes, repairing a Bosch dishwasher like model SHE43RF6UC is usually worth it when the unit is under about 10 years old and the problem is limited to a single, serviceable part. It becomes less cost-effective when multiple major components (pump, control, leaks) fail at the same time.

Quick way to decide (cost, age, and what failed)

Use these practical checkpoints before you buy parts or schedule service:

• Age: Under 6 to 10 years typically favors repair.
• Repair cost target: Keep the repair under about 50% of the cost of a comparable new dishwasher.
• Failure type: One clear failure (drain issue, fill issue, leak at the door) favors repair.
• Repeat problems: Frequent breakdowns in the last 12 months favors replacement.
• Installation condition: Poor drain hose routing or loose mounting can mimic “bad parts”; confirm setup per the installation guide.

Common repairs that are often worth it

These are typical “high value” fixes because they solve common symptoms without replacing the whole dishwasher:

Symptom	What to check first	Parts that are commonly involved (if needed)
Not filling or fills slowly	Water supply valve open, inlet screen, proper install clearances	Dishwasher water inlet valve 00622058
Not draining	Drain hose routing (high loop), clogs, drain pump operation	Dishwasher drain pump 00642239, dishwasher drain hose 00668108
Leaking at the bottom of the door	Door seal condition, debris on sealing surfaces	Dishwasher door seal, lower 00432490

Why installation details matter (even for “repair vs replace”)

If the drain hose is not installed with a section at least 20 inches off the cabinet floor, the dishwasher may not drain properly. That can look like a failing pump when the real fix is correcting the hose routing. Confirm the routing and mounting method in the installation guide.

When replacement makes more sense

Replacement is usually the better value when:

• The dishwasher is over 10 years old and needs a major repair.
• You suspect multiple expensive parts (circulation pump, control board, repeated leaks).
• The tub, door structure, or wiring has damage.

Helpful troubleshooting before you decide

• Check for stored fault information using Bosch dishwasher error codes.
• Clean filters and confirm spray arms rotate freely.
• Verify the drain hose has a proper high loop and is not kinked.

A Bosch dishwasher like model SHE43RF6UC typically lasts 10 to 15 years with normal household use. Consistent maintenance (especially keeping filters clean), correct installation, and good water quality are the biggest factors that help you reach the high end of that range; see the SHE43RF6UC manual for care guidance.

What affects lifespan the most

• Filter and sump cleaning: reduces strain on the circulation system and improves wash performance.
• Water quality: hard water can cause mineral buildup on spray arms, valves, and heaters.
• Proper installation: stable mounting and correct plumbing and electrical connections prevent leaks and vibration.
• Usage frequency: multiple heavy loads daily shortens life compared to 3 to 5 loads per week.
• Prompt leak/drain fixes: small issues can become pump or control problems if ignored.

Maintenance checklist (simple, high impact)

• Clean the filter regularly and rinse away debris.
• Run hot water at the sink before starting a cycle for better wash results.
• Use the right detergent amount; too much can cause residue and odors.
• Inspect the door seal area and wipe it clean.
• If you have hard water, use a dishwasher cleaner periodically to reduce scale.

Common wear items vs. major repairs

What you notice	Likely area	Typical next step
Not filling or fills slowly	Water inlet system	Check supply valve and consider the dishwasher water inlet valve 00622058
Not draining	Drain path or pump	Check filters, hose routing, then drain pump if needed
Poor cleaning	Circulation and filtration	Clean filters, check spray arms, then circulation pump if symptoms persist

Why it matters

Knowing the typical 10 to 15 year lifespan helps you decide whether to invest in a repair (like a pump, valve, or seal) or plan for replacement, especially if multiple symptoms show up at once.

The most common Bosch dishwasher issues are draining problems and poor cleaning, usually caused by a clogged filter system, blocked spray arms, or a restriction in the drain path. On the Bosch SHE43RF6UC, start with cleaning and inspection steps in the SHE43RF6UC owner’s manual.

Quick checks we recommend first

• Clean the filter area and remove debris (food, labels, glass) that can slow draining and reduce wash pressure.
• Confirm spray arms spin freely and the holes are not plugged.
• Make sure the sink drain or garbage disposal is not backing up into the dishwasher.
• Verify the drain hose has a proper high loop and is not kinked.
• Use the correct detergent amount and add rinse aid to improve drying and reduce spotting.

Common symptoms and the most likely causes

Symptom	Most common cause	What to check next
Water left in tub	Clogged filter or drain restriction	Drain hose routing, air gap (if used), sink/disposal blockage
Dishes not clean	Low wash pressure from blockage	Spray arm holes, filter, loading pattern
Won’t fill or fills slowly	Water supply restriction or valve issue	Shutoff valve fully open, inlet screen, dishwasher water inlet valve 00622058
Not drying well	Rinse aid low or poor loading	Rinse aid setting, plastics placement, cycle selection

When it’s likely a part problem

If cleaning and hose checks do not change performance, these parts are common suspects on dishwashers:

• Dishwasher fine filter 00441905 if the filter is damaged or won’t seal after cleaning
• Dishwasher drain pump 00642239 if you hear humming but water does not evacuate
• Dishwasher water inlet valve 00622058 if the unit runs but doesn’t bring in enough water
• Dishwasher circulation pump 00442548 if wash action is weak even with clean filters and clear spray arms

Why it matters

A restricted filter or drain path can make the dishwasher seem “broken” even though the control board and motor are fine. Restoring water flow and wash pressure usually fixes cleaning and draining complaints without major repairs.

Bosch “Silence Plus 44 dBA” is a quietness rating used on multiple Bosch dishwashers, not one single model. For your Bosch dishwasher model SHE43RF6UC, the exact dBA depends on the specific series and configuration listed on the rating label and in the SHE43RF6UC manual.

How to identify the exact model that is 44 dBA

Use the dishwasher’s model and FD information to match the correct product listing and noise rating.

• Check the model tag on the door edge or tub frame for the full model and FD number
• Look for “dBA” or “Silence Plus” wording in the product literature for that exact model
• Compare the control style (top control vs. front control) and handle style (pocket vs. bar)
• Match the tub type (stainless vs. hybrid) and rack layout to the correct series
• Use the manual to confirm features tied to the series (options, indicators, cycles)

What “44 dBA” means (and why it matters)

44 dBA is a low operating sound level; it typically indicates a premium quiet package (insulation, motor design, and filtration). In real kitchens, that usually means you can run the dishwasher during conversations or TV time with minimal disruption.

Noise rating	What you typically notice	Common fit for
39 to 44 dBA	Very quiet, often hard to hear	Open-concept kitchens
45 to 50 dBA	Quiet, soft wash sound	Most homes
51+ dBA	Noticeable wash and drain sounds	Utility areas, budget models

If you are shopping parts for a “Silence Plus” unit

Parts must match the full model number (and sometimes the FD number), even if two dishwashers share the same dBA rating. For example, fill problems are often tied to the dishwasher water inlet valve 00622058, while drain issues can involve the dishwasher drain pump 00642239.
