Do I need a technician for the E24 error?
You usually do not need a technician right away for an E24 error on your Bosch SHE44C02UC dishwasher; it most often points to a drain problem you can correct by cleaning the filter area and checking for a blocked or kinked drain path. Use the owner's manual self-help steps first.
- Cancel the cycle and let the dishwasher drain; then restart a short cycle.
- Remove and clean the filter(s) and the sump area under the filter (food, glass, labels).
- Check the drain hose routing under the sink for kinks, crushing, or a high loop that fell.
- If connected to a garbage disposal, make sure the disposal inlet knockout plug was removed.
- Clear the sink air gap (if your setup has one) and confirm the sink drain is not backing up.
- Listen for the drain pump during the drain portion; a loud hum with no draining points to a blockage.
If the basic checks do not restore normal draining, these model-matched parts are common fixes:
| Symptom you notice | Most likely area | Model-matched part to consider |
|---|---|---|
| Water stays in tub, hose is clear | Drain path restriction or split hose | Drain hose 00263099 |
| Pump hums but won’t move water | Pump area jam or pump housing issue | Pump 00267739 |
| Dishwasher never seems to fill correctly and then errors | Water level and flow problems can trigger drain faults later in the cycle | Dishwasher water inlet valve 00425458 |
E24 is a protection-style drain fault; when the dishwasher cannot move water out fast enough, it stops to prevent poor washing results and potential leaks. Fixing the drain path early also helps protect the pump and keeps cycle times normal.
- You have to pull the dishwasher out to access wiring, pump components, or under-unit plumbing.
- You find damaged wiring, burning smell, or repeated tripping of a breaker.
- The unit drains intermittently after you have cleaned the filter and verified the hose and sink connection.

What is the most common problem with a Bosch dishwasher?
The most common Bosch dishwasher problem we see is performance issues caused by maintenance and water flow: dishes not getting clean because the filter system or spray arm nozzles are clogged, or the dishwasher not draining because the drain path is restricted. For your Bosch SHE44C02UC, the care and self-help steps in the owner's manual address these first.
- Not cleaning well: clogged filter system, blocked spray arm nozzles, heavy soil buildup
- Not draining: kinked or clogged drain hose, clogged filters, blocked sink drain or air gap
- Long cycle times: cold incoming water (hot water not at the sink yet)
- White spots on dishes: rinse aid level too low
- Leaks or odors: debris on the inner door edges or door gasket
- Clean the filter system and remove any food debris.
- Check spray arm nozzles for blockage; remove the spray arms if needed to clear obstructions.
- Confirm the door closes and latches fully; a door that is not shut and latched can prevent starting.
- If it will not drain, inspect the drain path and hose routing.
- If cycles run unusually long, run the hot water at the nearest sink until it is hot, then start the cycle.
| Issue | Most likely area | What to look for |
|---|---|---|
| Not draining | Drain hose and filter system | Kinks, clogs, improper routing, clogged filters |
| Not filling or stops mid-cycle | Water supply | Supply valve shut off, restricted water flow |
| White film/spots | Rinse aid | Increase rinse aid dispensing |
If you suspect a drain restriction on this model, the drain hose 00263099 is a common wear or damage point to inspect for kinks, splits, or internal blockage.
Most “Bosch dishwasher problems” are really water movement problems. When the filter system, spray arms, or drain path are restricted, you get poor cleaning, standing water, odors, and longer run times. Regular cleaning and correct hose routing prevent repeat issues.
For error displays tied to draining, filling, or water flow, use our Bosch dishwasher error codes guide to match the code to the most likely checks.

How do I find the model number on my SHE44C02UC?
On your Bosch SHE44C02UC dishwasher, the model number is printed on the model and serial number label located on the right edge of the dishwasher door. Open the door and look along the inner right side for the label.
- Open the dishwasher door fully
- Check the inner right edge of the door (vertical edge)
- Look for a sticker or metal label with Model Number and Serial Number
- Write the model number exactly as shown (letters and numbers)
- Take a clear photo of the label for future parts ordering and service records
| Label item | What it’s used for |
|---|---|
| Model number | Matching the correct parts diagrams and replacement parts |
| Serial number | Identifying the production run and configuration |
| Customer service info | Reference details tied to your unit |
We use the model number to ensure you get manufacturer-approved parts that fit your exact Bosch dishwasher configuration. Even small model variations can change which door seal, latch, or water inlet valve fits.
Once you confirm the model number, compare it to the model shown on your parts list page (SHE44C02UC/17). If you are troubleshooting a symptom like not filling or leaking, the owner's manual also points you to the label location and helps narrow down likely causes.
