What does The SHE3AR55UC mean?
SHE3AR55UC is the Bosch dishwasher model number that identifies the exact design and parts list for your unit. We use it to match the correct replacement parts, installation requirements, and troubleshooting information for your dishwasher.
What the model number tells you (and what it does not)
The model number is mainly a parts and service identifier, not a “code” with a single universal meaning.
- It tells us which Bosch dishwasher platform and configuration you have.
- It helps match compatible parts like a water inlet valve, drain pump, or door lock.
- It’s used to look up installation specs and connection details.
- It does not indicate cycle time, error codes, or a “message” about the dishwasher.
Where to find the model number on the dishwasher
On Bosch dishwashers like model SHE3AR55UC, the model and serial tag is typically located on the right edge of the door when you open it.
- Open the door fully.
- Look along the right-hand inner edge of the door.
- Write down the model number and serial number exactly as shown.
Use the model number to get the right help
Once you confirm the model number, you can use it to choose the correct documentation and parts.
| What you need | Use the model number for | Example for this model |
|---|---|---|
| Install details | Hose routing, cabinet opening, connections | Installation guide |
| Common repairs | Matching exact replacement parts | Dishwasher water inlet valve 00622058 |
| Diagnostics | Interpreting fault codes and symptoms | Bosch dishwasher error codes |
Why it matters
Bosch often has multiple versions of a similar-looking dishwasher. Using the exact model number prevents ordering the wrong part (for example, a drain hose or control board that will not fit) and helps ensure correct installation.

What is the average lifespan of SHE3AR55UC?
A Bosch dishwasher like model SHE3AR55UC typically lasts 10 years with normal household use. Lifespan depends most on water quality, how often it runs, and basic maintenance like keeping the filter area clean and preventing drain clogs.
What affects lifespan most
- Hard water and heavy detergent use can leave mineral buildup on internal parts
- Frequent cycles (multiple loads per day) increase wear on the pump and heater
- Poor draining or standing water strains the drain system
- Leaks can damage wiring, the control, and insulation
- Overloading racks can break rollers and stress the door
Maintenance that extends service life
Use these habits to reduce wear on the motor, heat pump, and seals:
- Run hot water at the sink before starting a cycle
- Clean the sump and filter area regularly (per the installation guide)
- Keep the spray arms clear of debris
- Use the right detergent amount for your water hardness
- Inspect the door seal for nicks and flattening
Common “end-of-life” symptoms and what they point to
| Symptom | Most likely system involved | Typical next step |
|---|---|---|
| Won’t drain | Drain path, pump, check valve | Clear blockage, then test pump |
| Won’t fill | Water supply, inlet valve | Confirm supply, then test valve |
| Not drying | Heater/heat pump, rinse aid use | Check settings, then heat system |
| Leaks | Door seal, hoses, clamps | Inspect and replace worn seals |
Why it matters
Knowing the typical 10-year lifespan helps you decide whether to repair (often cost-effective for a drain or fill issue) or plan a replacement if multiple major systems are failing.

What replacement parts are most commonly needed for the SHE3AR55UC?

Most commonly needed replacement parts
These are frequent wear or failure items on dishwashers:
- Fill components: dishwasher water inlet valve 00622058, dishwasher water inlet port 00645147
- Drain components: dishwasher drain pump 00611332, dishwasher drain hose 00668108 (also dishwasher drain hose 00645149), dishwasher check valve 00611320

- Controls and starting: dishwasher door lock 00630783, dishwasher on/off switch 00611295
Quick symptom-to-part guide
| What you notice | Parts to check first | Why |
|---|---|---|
| Dishwasher won’t fill | Inlet valve, inlet port | Water cannot enter the tub |
| Water left in bottom | Drain hose, check valve, drain pump | Drain path is blocked or pump is weak |
| Leaking at the door | Door seal | Seal no longer compresses evenly |
| Lower rack derails or sticks | Lower roller, roller kit, slide rail | Worn wheels and rails bind under load |
How we recommend confirming the right part
- Verify the symptom (fill, drain, leak, or rack issue)
- Check for simple causes first (kinked hose, clogged air gap, debris in sump)
- Use the exploded-view diagrams and steps in the installation guide
- Replace only the failed component, then run a test cycle
Why it matters
Dishwashers often show the same symptom for different reasons (for example, “not draining” can be a hose blockage or a failed pump). Matching the symptom to the correct system saves time and prevents repeat repairs.
