Can I still use my appliance with an E22 error?
We don’t recommend running your Bosch dishwasher model SHE45M05UC with an E22 error because it commonly points to a drainage or filtering problem; continuing to run cycles can leave dirty water in the sump, reduce cleaning performance, and strain the drain system. Use the SHE45M05UC manual to confirm the reset and cleaning steps for your exact control panel.
E22 is most often tied to restricted water flow through the filter area or poor draining. Start with the simplest checks first.
- Clean the filter assembly in the bottom of the tub (remove debris, grease, labels)
- Check for standing water in the sump after canceling/draining
- Inspect the drain hose routing for kinks or a clogged high loop/air gap
- Verify the sink drain or garbage disposal inlet is clear (common blockage point)
- Listen for the drain pump running during drain; a loud hum can indicate a jam
- Turn off power at the breaker.
- Remove the lower rack and clean the filter area thoroughly.
- Check the drain path for obstructions (glass, bones, twist ties).
- Restore power and run a cancel/drain to see if water evacuates.
If the dishwasher still won’t drain reliably, the drain pump or drain hose is a common next focus.
| What you observe | Most likely cause | What we do next |
|---|---|---|
| Water remains in tub, pump hums | Pump jam or failing pump | Inspect/replace drain pump 00642239 |
| Slow drain, intermittent E22 | Partial clog in hose or plumbing | Inspect/replace dishwasher drain hose 00668108 |
| Poor wash plus drainage symptoms | Circulation restriction or sump issues | Check filters; inspect sump filter 00441905 |
A dishwasher that cannot move water correctly may redeposit soil, trigger repeated error codes, and overwork components like the drain pump and recirculation system.
- You smell burning or see water leaking under the unit
- The breaker trips when the dishwasher tries to drain
- E22 returns immediately after cleaning the filter and checking the drain hose

What's the most common problem with a Bosch dishwasher?
On the Bosch SHE45M05UC dishwasher, the most common issues we see are poor cleaning and draining problems. In many cases, the root cause is simple maintenance (a dirty filter or blocked spray arms), but a drain pump or water inlet valve can also be the culprit.
- Dishes come out dirty or gritty: clogged filter, blocked spray arms, or low incoming water temperature
- Water left in the bottom: restricted drain path, kinked hose, or a failing drain pump
- Not filling with water: closed supply valve, clogged inlet screen, or a failing inlet valve
- Odd noises during wash: debris in the sump area, worn pump components, or a struggling recirculation pump
- Leaks at the door: worn or mis-seated door seal
For model-specific maintenance steps and error indicator guidance, use the SHE45M05UC manual.
- Clean the filter and sump area; remove labels, glass, and food debris.
- Spin and rinse spray arms; clear any plugged jet holes.
- Confirm hot water supply to the dishwasher (many homes target about 120°F at the sink).
- Check the drain hose routing for kinks and for a proper high loop/air gap setup.
- Run a cleaning cycle with a dishwasher cleaner to reduce grease and mineral buildup.
| Symptom | Most likely system | Part to consider (if checks don’t fix it) |
|---|---|---|
| Won’t drain or drains slowly | Drain system | Drain pump 00642239 |
| Won’t fill or fills weakly | Water inlet | Dishwasher water inlet valve 00607335 |
| Poor wash pressure, weak spray | Wash circulation | Dishwasher recirculation pump assembly 00442548 |
| Leaks at bottom of door | Door sealing | Door seal 00432490 |
Bosch dishwashers rely on efficient water flow and filtration. A partially clogged filter or restricted drain can cause poor cleaning, standing water, longer cycles, and extra wear on the pump and seals.
If you’re seeing an error display or repeating beeps/lights, match the code to the symptom using Bosch dishwasher error codes.

How do I find the model number on my SHE45M05UC?
For your Bosch dishwasher, the model number is printed on the appliance’s rating label, usually on the inside edge of the door. Open the door and look along the left or right side of the door frame; confirm the full model and the slash version (for example, SHE45M05UC/53).
Check these common label locations first:
- Inside the door opening on the left side wall (vertical edge)
- Inside the door opening on the right side wall (vertical edge)
- Along the top edge of the tub opening, just under the countertop
- On the inner door edge near the latch area
Use a flashlight and wipe the area with a damp cloth if the label is hard to read.
Bosch dishwashers often show multiple identifiers. Capture all of these so we can match parts correctly:
- Model number (example format: SHE45M05UC)
- FD number (factory date code)
- E-Nr (Bosch model identifier, if shown)
- Slash version (example: /53)
| Label item | What it means | Why it matters |
|---|---|---|
| Model number | The base model (SHE45M05UC) | Gets you to the correct parts list and diagrams |
| /XX version | The revision (such as /53) | Ensures the exact-fit part for your production run |
| FD number | Date code | Helps confirm compatible updates |
Bosch commonly updates components during a model’s production run. Using the full model plus the /53 version helps us match the correct control parts, pumps, seals, and racks for your dishwasher.
Your SHE45M05UC owner’s manual typically shows where the rating label is located and how Bosch lists the model and FD information.
