Are all dishwashers 55cm deep?
No. Many built-in (integrated) dishwashers are designed around a roughly 55 cm cabinet depth, but dishwasher depth is not universal and varies by style and installation. For your Bosch SHX4AT55UC, use the depth and cutout requirements in the installation guide to confirm the exact fit.
Dishwasher depth depends on whether you are measuring the cabinet box, the door, or the overall depth including the handle.
- Built-in/integrated models: often around 55 cm cabinet depth
- Freestanding/portable models: commonly deeper than 55 cm
- Overall depth (door closed): can increase if there is a thicker door or protruding handle
- Overall depth (door open): always much deeper and matters for aisle clearance
Use a tape measure and match the measurement to the spec you are checking.
- Measure the cabinet opening depth from the back wall to the front of the cabinet
- Measure the dishwasher case depth (back to front of the tub area)
- Measure overall depth with the door closed (include the door and handle if present)
- Confirm there is room for water line, drain hose, and power cord behind the unit
| Measurement you need | Where you measure | Why it matters |
|---|---|---|
| Cabinet opening depth | Back wall to cabinet face | Determines if the unit can slide in fully |
| Dishwasher case depth | Back of unit to front of case | Fit inside the opening |
| Overall depth (door closed) | Back of unit to front of door/handle | Door/handle can stick out past cabinets |
If the opening is too shallow, the dishwasher may not sit flush, the door may not align with adjacent cabinets, and hoses can kink or pinch. Verifying the cutout depth in the installation guide prevents fit issues before installation.

What is the most common problem with a Bosch dishwasher?
The most common Bosch dishwasher issue we see is a drain problem: the dishwasher will not drain fully, leaves water in the tub, or stops mid-cycle because water cannot pump out. On Bosch model SHX4AT55UC, this is usually tied to a clogged filter area, a restricted drain hose, or a failing drain component.
- Standing water in the bottom after the cycle
- Humming sound but little or no draining
- Cycle stops and the unit beeps or shows an error
- Dirty water backing up into the tub
- Dishes come out with debris because water is not circulating and draining correctly
- Turn off power at the breaker before reaching into the sump area.
- Remove and clean the filter and sump area (food, glass, labels).
- Check the drain hose routing for kinks and confirm a proper high loop/air gap setup (per the installation guide).
- Inspect the sink drain/disposer inlet where the dishwasher hose connects for blockage.
- Run a short cycle and listen: a strong drain pump sound with no water movement points to a restriction; a weak or noisy pump points to a failing pump.
Drain and fill issues are the top two “most common” categories. These are the model-matched parts we often see involved:
| Problem type | What it looks like | Common part to check |
|---|---|---|
| Not draining | Water left in tub | Drain pump 00611332 |
| Slow/no fill | Little water enters, poor wash | Dishwasher water inlet valve 00622058 |
| Backflow | Dirty water returns to tub | Dishwasher check valve 00611320 |
| Leaks at door | Water at front edges | Dishwasher door seal 00645141 |
A dishwasher that cannot drain correctly often cannot wash correctly either. Standing water can trigger error codes, cause odors, and leave detergent and soil redepositing on dishes. If you also see an error, use the Bosch dishwasher error codes guide to match the symptom to the most likely cause.

Is it worth repairing a 12 year old Bosch dishwasher?
Yes, repairing a 12-year-old Bosch dishwasher like model SHX4AT55UC is usually worth it when the problem is a common, moderate-cost failure (drain, fill, leak, or latch issues). Replacement makes more sense when the repair is a major, high-cost job such as a pump and motor assembly.
We use a simple rule: if the repair total (parts plus labor) is under about 50% of the cost of a comparable new dishwasher, repair is the better value. If it is well over that, replacement is typically the smarter move.
Typical repair cost drivers on SHX4AT55UC include:
- Water not filling: dishwasher water inlet valve 00622058
- Not draining: drain pump 00611332 or a restricted drain path
- Leaks at the door: dishwasher door seal 00645141
- Won’t start or won’t latch: dishwasher door latch assembly 00611312
- Major wash performance failure: dishwasher pump and motor assembly 00705174
- Won’t fill or fills slowly: inlet valve, shutoff valve not fully open, clogged screen
- Won’t drain: drain pump, drain hose routing, check valve
- Leaks: door seal, loading issues, oversudsing, loose hose connections
- Poor cleaning: filters/spray arms need cleaning, water temperature, turbidity sensor issues
- Dead or intermittent power: door latch switch, on/off switch, wiring
| What’s wrong | Usually worth repairing? | Why |
|---|---|---|
| Drain issue (clog, hose, pump) | Yes | Often a targeted fix with moderate parts cost |
| Door leak (seal) | Yes | Straightforward repair that restores normal operation |
| Rack roller/wheel broken | Yes | Low-cost convenience repair |
| Pump and motor assembly failure | Sometimes | Higher-cost part; compare total repair cost to replacement |
A 12-year-old dishwasher can still deliver good results if the tub is sound and the failure is isolated. Fixing a fill, drain, or seal problem often restores reliability without the expense and hassle of replacing the unit.
- Use the SHX4AT55UC owner’s manual for cycle options, reset steps, and care guidance.
- If you’re seeing a fault code, use Bosch dishwasher error codes to narrow the problem before ordering parts.
