What's the most common problem with a Bosch dishwasher?
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.
- 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
- Clean the filter area and remove debris from the sump.
- Inspect and clear spray arm holes (food, labels, mineral scale).
- Confirm hot water is available at the sink before starting the cycle.
- Check the drain hose routing for kinks and a proper high loop.
- Use rinse aid and load so spray arms spin freely.
| 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 |
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.
- 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.

Do I need a technician for the E24 error?
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.
- 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.
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.
| 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 |
E24 is the dishwasher protecting itself from running with standing water. Clearing the drain path quickly helps prevent odors, poor cleaning, and repeat shutdowns.

Is the Bosch Silence Plus a good dishwasher?
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.
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
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 |
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
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.
