Which dishwasher to stay away from?
If you’re deciding what dishwasher to avoid, we focus less on “bad brands” and more on red flags that predict headaches: poor parts availability, frequent leak or drain complaints, and weak service support. For a Bosch dishwasher like model SHX7ER55UC, checking installation requirements in the installation guide helps prevent many of the problems people blame on the dishwasher.
What to avoid (practical red flags)
- Models with repeated reports of leaking at the door or base (often tied to installation or worn seals)
- Units that require uncommon parts or have limited parts availability
- Dishwashers with frequent “won’t start” or intermittent power complaints (often control or door-latch related)
- Designs with hard-to-clean filters or sump areas that clog easily
- Very low-priced models that cut drying performance (more wet plastics, more reruns)
What to look for instead
Reliability is usually best when the dishwasher is installed correctly, has stable water temperature and pressure, and has common serviceable parts.
- Clear installation specs (drain hose routing, electrical, water supply)
- Strong leak protection and a solid door seal design
- Easy access to filters and sump for routine cleaning
- Readily available replacement parts (rollers, valves, sensors, seals)
Installation issues that get mistaken for “a bad dishwasher”
The SHX7ER55UC installation instructions call out a few items that directly affect performance and reliability:
- Drain hose must loop up at least 20 inches off the cabinet floor to help prevent drain problems
- Hot water supply should be about 120°F; cooler water can increase run time
- Supply pressure should be 15 to 145 psi
- Do not run the dishwasher until it’s completely installed (tip-over risk when uninstalled)
Quick spec snapshot (common trouble preventers)
| Item | Target | Why it matters |
|---|---|---|
| Water temperature | ~120°F | Helps cleaning without reducing detergent effectiveness |
| Water pressure | 15 to 145 psi | Prevents fill problems and weak wash action |
| Drain hose high loop | 20 in. minimum | Helps prevent poor draining and backflow |
Why it matters
Most “dishwasher to stay away from” complaints trace back to leaks, no-drain, or no-start symptoms. Those are often preventable with correct installation and basic maintenance, and they are also the easiest problems to diagnose using the model’s documentation.

What's the most common problem with a Bosch dishwasher?
The most common Bosch dishwasher problems are poor cleaning and drainage issues caused by routine buildup (filters, sump area, spray arms) or a restriction in the drain path. On the Bosch SHX7ER55UC, regular cleaning and a quick drain check solve many day-to-day complaints; use the owner's manual for the exact care steps and cycle guidance.
Most common symptoms (and what they usually point to)
- Dishes not clean: clogged filter, blocked spray arm holes, low water temperature, overloading
- Not draining: kinked/blocked drain hose, clogged sump area, stuck check valve
- Odor: food debris in filter/sump, standing water, infrequent hot cycles
- Leaks at the door: worn or dirty door seal, door not closing fully
- Detergent cup not opening: dispenser issue, blocked by tall items, incorrect loading
Quick checks we recommend first
- Turn off power at the breaker before inspecting internal parts.
- Clean the filter area and remove any debris from the sump.
- Spin spray arms by hand and clear clogged holes.
- Confirm the sink drain and garbage disposer inlet are clear (if connected).
- Check for a smooth door close and a clean sealing surface.
Parts that commonly relate to these problems
| Symptom | Commonly involved part | What it affects |
|---|---|---|
| Not draining or backflow | Dishwasher check valve 00611320 | Prevents dirty water from returning to the tub |
| Leaking at the door | Dishwasher door seal 00263096 | Keeps wash water inside the tub |
| Detergent not dispensing | Dishwasher detergent dispenser assembly 00645208 | Releases detergent at the right time |
| Poor cleaning results | Dishwasher turbidity sensor 00611323 | Helps the control adjust wash based on soil level |
Why it matters
Most “Bosch dishwasher problems” start as airflow, water flow, or drainage restrictions. Fixing the root cause improves cleaning, reduces odor, and helps protect key components like the circulation system and heater.
When an error code shows up
If your SHX7ER55UC displays an error code, match it to the troubleshooting steps in Bosch dishwasher error codes before replacing parts.

Which Bosch dishwasher is the highest rated?
There is no single “highest-rated” Bosch dishwasher across all years and reviewers; ratings change based on what’s measured (cleaning, drying, noise, reliability, and price). In most Bosch lineups, the top ratings usually cluster in the premium tiers (800 Series and Benchmark) because they include the most advanced drying and quieting features. For feature definitions and operating details on your Bosch SHX7ER55UC, use the owner's manual.
What “highest rated” usually means (and what to compare)
Different sources score dishwashers differently; use these criteria to identify the best Bosch model for your priorities:
- Drying performance (especially plastics)
- Noise level (lower dBA is quieter)
- Cleaning and filtration (soil handling, spray coverage)
- Rack flexibility (third rack, adjustability)
- Reliability and parts support (long-term ownership)
Typical Bosch tier comparison
This is the most practical way to narrow down “best” without relying on one changing ranking list.
| Bosch tier | What it’s known for | Best for |
|---|---|---|
| Benchmark | Flagship features, premium build, very quiet | Top-end performance and finish |
| 800 Series | Premium drying and very quiet operation | Best overall mix of features and price at the high end |
| 500 Series | Strong feature set, upgraded convenience | Midrange value with premium touches |
| 300 Series | Core features and strong everyday performance | Value-focused buyers who still want key upgrades |
| 100 Series | Basics and strong cleaning value | Lowest upfront cost |
How this relates to your SHX7ER55UC
Your Bosch SHX7ER55UC is a higher-end Bosch dishwasher; getting “top-rated” results day to day comes from correct setup and maintenance.
- Use rinse aid and the correct detergent amount
- Load to keep spray arms from being blocked
- Clean the filter regularly
- Fix rack issues that affect loading (a worn wheel like the dishwasher dishrack roller, lower 00611475 can make the rack sit crooked)
- Address performance symptoms using Bosch dishwasher error codes
Why it matters
“Highest rated” is not one permanent Bosch model; it is the model that best matches your kitchen (noise) and household needs (drying, racks, cycle time). Comparing by criteria prevents overpaying for features you will not use.
