Bosch SHE43R55UC/64 dishwasher Parts

The most common Bosch dishwasher problem is poor wash performance caused by restricted water flow (a dirty filter, blocked spray arms, or low incoming water temperature). On the Bosch SHE43R55UC, the next most common issues are draining problems and not filling, which often trace back to a clog or a failing pump or inlet valve.

Most common symptoms and what they usually mean

• Dishes come out dirty or gritty: filter/sump restriction, spray arm blockage, or weak circulation
• Water left in the tub: drain path clog, kinked drain hose, or a weak drain pump
• No water or very little water entering: supply valve closed, inlet screen clogged, or a failing inlet valve
• Leaks at the bottom/front: door seal wear, loose hose connections, or overfilling
• Cycle seems to run forever: heating issue, low water temp, or sensor-related wash adjustments

Quick checks we recommend first (fast, no parts)

1. Clean the filter area and remove debris from the sump.
2. Inspect and clear spray arm holes (food, labels, mineral scale).
3. Confirm hot water is available at the sink before starting the cycle.
4. Check the drain hose routing for kinks and a proper high loop.
5. Use rinse aid and load so spray arms spin freely.

When a part is the likely fix

Symptom	Most likely area	Common part to check on this model
Not filling	Water supply/inlet	Dishwasher water inlet valve 00622058
Not draining	Drain system	Drain pump 00642239
Leaking at door	Door sealing	Door seal 00432490
Poor cleaning with normal fill	Circulation	Dishwasher recirculation pump assembly 00442548

Why it matters

Bosch dishwashers are efficient, so small restrictions (filter buildup, spray arm blockage, mineral scale) can quickly reduce cleaning and draining performance. Addressing maintenance items early often prevents pump strain and repeat clogs.

Helpful references

• Use the SHE43R55UC user manual for the model-specific care, maintenance, and self-help checks.
• If you see a fault code, match it using Bosch dishwasher error codes to narrow the cause before replacing parts.

You do not always need a technician for an E24 error on your Bosch SHE43R55UC dishwasher. E24 points to a draining problem, and many causes are simple to correct at home, such as a blocked filter area, a kinked drain hose, or a clogged sink disposal inlet.

What to check first (safe DIY steps)

• Cancel the cycle and let the unit attempt to drain.
• Check the sink drain and garbage disposal for a clog (a backed-up sink can trigger E24).
• Inspect the drain hose routing under the sink for kinks, pinches, or a low spot holding water.
• If your setup uses an air gap, check it for blockage.
• Clean the filter area in the bottom of the tub and remove any debris.

For model-specific access and cleaning steps, follow the SHE43R55UC owner's manual.

When a technician is the better choice

We recommend service when the dishwasher is hard-wired, you see repeated E24 after clearing the drain path, or you suspect an internal drain component issue.

Common “service-level” causes include:

• Failed drain pump
• Electrical issue to the drain pump
• Drain pump obstruction that requires disassembly
• Control not powering the drain circuit correctly

A likely replacement part for a true drain-pump failure is the drain pump 00642239.

Quick symptom guide

What you notice	Most likely cause	What to do
Water remains in tub	Blocked drain path or pump issue	Check hose, air gap, filter area; then test drain
Drains slowly	Partial clog in hose or plumbing	Clear hose and sink/disposal inlet
E24 returns every cycle	Pump, wiring, or control issue	Consider pump inspection or service

Why it matters

E24 is the dishwasher protecting itself from running with standing water. Clearing the drain path quickly helps prevent odors, poor cleaning, and repeat shutdowns.

Yes. Bosch Silence Plus dishwashers are a strong choice for quiet operation and dependable cleaning; on Bosch model SHE43R55UC, correct installation and smart loading habits make the biggest difference in day-to-day results.

What “good” means for this Bosch dishwasher

A “good” dishwasher is quiet, cleans consistently, and drains reliably. These factors usually decide satisfaction:

• Low noise during wash and drain
• Strong spray coverage (don’t block spray arms)
• Proper detergent and rinse aid use
• Clean filters and clear drain path
• Correct drain hose routing and leveling

Installation details that affect performance (SHE43R55UC)

The SHE43R55UC installation guide highlights requirements that directly impact washing and draining.

• Install the drain hose with a high loop; keep a portion at least 20 inches off the cabinet floor to help prevent draining problems
• Use a dedicated 120V, 60 Hz grounded circuit with a 15 amp breaker/fuse
• Keep water and electrical supply lines separated under the dishwasher
• Avoid applying heat near the inlet area during plumbing work; heat can damage the inlet valve

What you notice	Often tied to	What to check first
Poor draining	Drain routing or restriction	High loop, hose kinks, sink/disposer connection
Weak cleaning	Loading or restricted circulation	Filter cleaning, spray arm blockage
Unexpected noise	Contact or loose items	Leveling, rack loading, toe panel fit

When a part issue makes performance look “bad”

If the dishwasher won’t fill or won’t drain, a single failed part can overshadow an otherwise solid Bosch design.

• Dishwasher water inlet valve 00622058 for no fill or slow fill
• Drain pump 00642239 for standing water after a cycle
• Sump filter 00441905 for restricted water flow from debris

Why it matters

Silence Plus models earn their reputation when the unit is installed to spec and the wash system stays clear; those basics prevent many “not cleaning” and “not draining” complaints.
