Do I need a technician for the E24 error?
You usually do not need a technician right away for an E24 error on a Bosch SHE9ER55UC dishwasher; it most often points to a drain restriction you can clear by cleaning the filter area and checking the drain pump cover area for debris. Use the owner's manual Self Help steps first.
What to do first (safe DIY checks)
- Turn off power to the dishwasher at the breaker before reaching into the sump area.
- Remove and clean the filters; rinse off grease and trapped food.
- Scoop out any standing water in the bottom (a sponge works well).
- Open the drain pump cover area and remove foreign objects (glass, labels, bones).
- Reinstall the pump cover and filters securely, then restore power and try a drain or cancel cycle.
Drain path checklist (common E24 causes)
E24 is a drain flow problem; the restriction is usually in one of these places:
| Drain area | What to look for | Typical fix |
|---|---|---|
| Filter and sump | Food, broken glass, sludge | Clean filters and sump |
| Drain pump inlet | Debris under/around pump cover | Clear debris, reseat cover |
| Drain hose | Kinked hose, clog, high loop issue | Straighten hose, clear blockage |
| Sink connection | Plugged disposal inlet or drain port | Clear the inlet/port |
When a technician makes sense
Schedule service when the E24 returns immediately after you have cleaned the filters and confirmed the drain hose and sink connection are clear, or when you hear the pump humming but water does not move.
Parts that commonly relate to drain problems (when troubleshooting points there):
- Dishwasher check valve 00611320 (can restrict flow if stuck)
- Dishwasher sump hose 00668104 (can clog or leak)
- Dishwasher aquastop assembly 00674387 (water protection system issues can affect operation)
Why it matters
Running the dishwasher with a restricted drain can leave dirty water in the tub, cause poor cleaning, and trigger repeat error codes. Clearing the drain path early prevents repeat shutdowns and helps protect the pump.

What's the most common problem with a Bosch dishwasher?
The most common Bosch dishwasher problems are poor cleaning and draining issues caused by food debris buildup in the filter and pump area, plus occasional leaks from suds or a door seal that is out of place. For your Bosch SHE9ER55UC, the owner's manual Self Help section focuses on these same basics.
Most common symptoms and what usually causes them
- Not cleaning well: clogged filter, blocked spray arms, or incoming water not hot enough
- Not draining: debris in the filter or pump cover area, or a restriction in the drain path
- Won’t start: door not fully latched, cycle not selected before closing, delay start active, or power interruption
- Leaks: wrong detergent causing suds, door seal pulled out of its track, blocked condensation vent
- Odor: food debris in filters; needs routine cleaning and an occasional vinegar cycle
Quick checks we recommend first (SHE9ER55UC)
- Confirm the door is fully latched and a cycle is selected before closing.
- Run hot water at the sink closest to the dishwasher before starting a cycle (helps cleaning and cycle time).
- Clean the filter system; if standing water is present, disconnect power, remove filters, and check the pump cover area for foreign objects (the manual outlines this process).
- Check for suds; use only automatic dishwasher detergent.
- Inspect the door seal to make sure it is seated in the track.
Common problem vs. best next step
| Problem you notice | Most likely cause | Best next step |
|---|---|---|
| Dishes gritty or dirty | Filter or spray arm blockage | Clean filters; check spray arms for clogs |
| Water left in tub | Debris at pump cover or drain restriction | Clear filter and pump area; verify drain path |
| Leaking at door | Suds or door seal out of track | Correct detergent; reseat seal |
| Bad smell | Food debris buildup | Clean filters; run a vinegar cycle |
Parts that often come up during troubleshooting
If cleaning and inspection point to a worn or failed component, these model-matched parts are commonly involved:
- Dishwasher door seal 00263096 (leaks at the door)
- Dishwasher check valve 00611320 (drain backflow or draining complaints)
- Dishwasher turbidity sensor 00611323 (cycle performance issues tied to soil sensing)
Why it matters
Bosch dishwashers rely on a clean filter and clear pump area to maintain wash pressure and drain performance. When debris builds up, you can see longer cycles, poor cleaning, odors, and intermittent draining problems.

How do I find the model number on my SHE9ER55UC?
The model number and serial number for your Bosch dishwasher are printed on a label on the edge of the dishwasher door. Open the door and look along the inner door edge (typically the top or side edge) for the rating label.
Where to look (quick checklist)
- Open the dishwasher door fully
- Check the edge of the door (not the front panel)
- Look for a rating label with model and serial information
- Wipe the area with a damp cloth if the label is dusty
- Write the model number exactly as shown (letters and numbers)
What the label usually includes
| Label item | What it’s used for | Example |
|---|---|---|
| Model number | Matching the correct parts and diagrams | SHE9ER55UC |
| Serial number | Identifying production details for service records | Varies |
| Electrical ratings | Verifying power requirements | Varies |
Why it matters
Using the exact model number helps us match your dishwasher to the correct Bosch parts list (like a door seal, detergent dispenser, or circulation pump) so you avoid ordering a similar-looking part that does not fit.
Helpful tip for this model family
The Bosch SHE9ER55UC models use hidden controls; you often open the door to access settings and start options. That same open-door position makes it easy to spot the model and serial label.
For diagrams and model-specific details, use the SHE9ER55UC owner’s manual.
