What's the most common problem with a Bosch dishwasher?
The most common issues we see with Bosch dishwashers like model SHE55C05UC are poor cleaning (usually from a dirty filter or blocked spray arm), draining problems (often a clog or pump issue), and leaks around the door (seal or latch alignment). Regular cleaning and correct water temperature prevent many of these problems.
- Dishes come out dirty: clogged filter, blocked spray arm holes, low water temperature, or overloading.
- Dishwasher won’t drain: food debris in the sump, kinked/blocked drain hose, or a failing drain pump.
- Bad odors: food buildup in the filter area and sump; infrequent cleaning.
- Leaks at the door: worn door seal, door not latching squarely, or hinge wear.
- Won’t start or stops mid-cycle: door not fully latched, control lock settings, or an error code.
- Clean the filter area and remove any standing water or debris.
- Spin the spray arms by hand; clear any blocked jets.
- Run the hot water at the sink for 1 to 2 minutes before starting a cycle.
- Confirm the door closes firmly and the latch engages.
- If the unit shows an error, match it using Bosch dishwasher error codes.
| Symptom | Common fix | Example part on this model page |
|---|---|---|
| Not draining | Replace drain pump or clear drain path | Drain pump 00642239 |
| Leaking at door | Replace lower door seal | Door seal 00432490 |
| Poor wash circulation | Replace recirculation pump assembly | Dishwasher recirculation pump assembly 00442548 |
Most “common Bosch dishwasher problems” start as airflow, water flow, or sealing issues. Keeping water hot (about 120°F) and keeping the wash system clear helps your pump, spray arms, and drain system work correctly, which improves cleaning and reduces odors.
For model-specific operating and care steps (including cleaning and self-help guidance), use the owner's manual.

Can I still use my appliance with an E22 error?
We do not recommend running your Bosch SHE55C05UC dishwasher with an E22 error because it points to a drain or filter restriction; continuing to run it can leave standing water in the tub and strain the drain system. Clear the filter area first, then test a drain/reset cycle.
E22 is most commonly tied to water not draining properly due to a clogged filter system or blockage in the sump area.
Check these items first:
- Remove and clean the filter(s) and the area underneath them (food debris, glass, labels).
- Make sure the drain path in the sump is clear and the impeller area is not jammed.
- Verify the sink drain or garbage disposer inlet is not blocked.
- Confirm the drain hose is not kinked, crushed, or routed incorrectly.
- Run Cancel/Reset to force a drain and listen for the drain pump.
For model-specific filter removal and cleaning steps, follow the owner's manual.
Use this quick guide after you clean the filter area.
| What you see after cleaning | What to do next |
|---|---|
| Tub drains fully on Cancel/Reset | Run a short cycle and recheck for the code |
| Water remains in tub, pump sounds strained | Stop and inspect drain hose and pump area |
| No drain sound at all | Check for a blockage, then plan for a drain pump diagnosis |
If cleaning does not fix it, the issue is often in the drain path components.
Common related parts for this model include:
- Drain pump 00642239 (if the pump will not move water)
- Dishwasher drain hose 00668108 (if the hose is restricted or damaged)
- Float 00165301 (if overfill protection is stuck and affects operation)
An E22 condition means the dishwasher is not moving water out as designed. Fixing the restriction quickly helps prevent odors, poor cleaning, and extra wear on the drain pump and recirculation system.

Which Bosch dishwasher is the highest rated?
Bosch’s highest-rated dishwashers are typically the premium series models (especially the 800 Series and Benchmark Series) because they combine very quiet operation, strong wash performance, and upgraded drying features. For feature details and cycle options on your Bosch SHE55C05UC, use the owner's manual.
Ratings vary by reviewer, but they usually weigh these factors most heavily:
- Noise level (dBA): quieter models score higher in kitchens that are open to living areas
- Drying performance: plastics and mixed loads are the toughest test
- Cleaning performance: soil removal on baked-on foods and heavy loads
- Rack design and capacity: third rack, adjustability, and smooth-glide rails
- Reliability and service history: fewer repeat issues over time
These are the common “tiers” shoppers compare when looking for top-rated Bosch models.
| Bosch series | Typical strengths | Best for |
|---|---|---|
| 300 Series | Strong value, quiet, solid cleaning | Most households wanting Bosch quality at a lower cost |
| 500 Series | More features, improved drying options | Buyers who want a step up in convenience |
| 800 Series | Premium quietness, top drying performance | Shoppers prioritizing drying and low noise |
| Benchmark Series | Flagship features and design upgrades | Buyers who want the most premium Bosch lineup |
Your SHE55C05UC is a specific Bosch dishwasher model; the “highest rated” answer depends on whether you’re comparing within your current series or shopping across the full Bosch lineup. If you’re troubleshooting performance (not shopping), the fastest path is to check settings, filters, and any stored fault indicators.
- Confirm the selected cycle and options match your load type
- Clean the filter area and check spray arm movement
- Verify hot water supply is around 120°F (common dishwasher target)
- If you see an error, use a Bosch-specific code list for interpretation
For code meanings and next steps, we recommend our Bosch dishwasher error codes guide.
A “top-rated” dishwasher is usually the one that matches your priorities (quietness, drying, racks, cycle time). Knowing what reviewers score helps you compare series fairly and avoid paying for features you will not use.
