Bosch SHE45M05UC/48 dishwasher Parts

Yes, you can sometimes run a cycle with an E22 error on your Bosch dishwasher model SHE45M05UC, but we recommend fixing the cause first because E22 commonly points to a drainage or filter restriction that can lead to poor cleaning and repeated stopping. Use the steps in the SHE45M05UC owner’s manual before running another full load.

What E22 usually means on a Bosch dishwasher

On Bosch dishwashers, E22 is most often tied to water not moving through the filter and sump area correctly (food debris, blocked filter, or restricted drain path). That can leave dirty water in the tub and strain the pump.

Quick checks to do before you run it again

• Turn the dishwasher off, then cancel and drain (if the controls allow).
• Remove and clean the filter area; rinse off grease and debris.
• Check the drain hose for kinks, crushing, or a clog.
• Make sure the sink drain or garbage disposal connection is clear.
• If the unit hums but will not drain, inspect the drain pump area for obstructions.

Parts that are commonly involved (when cleaning is not enough)

If E22 returns right after cleaning, a restricted filter system or a weak pump can be involved.

Symptom you notice	Most likely area to check	Example part for this model
Standing water after cancel/drain	Drain path or drain pump	Drain pump 00642239
Poor wash pressure, gritty water	Sump and circulation path	Sump filter 00441905

Why it matters

Running repeated cycles with restricted draining can leave soil redeposited on dishes, cause odors, and keep the dishwasher from completing cycles normally. Clearing the restriction first protects wash performance and helps prevent repeat errors.

Helpful reference

• Use Bosch-specific code guidance in Bosch dishwasher error codes to match the display behavior to the most likely cause.

For the Bosch SHE45M05UC dishwasher, the most common problems we see are cleaning and draining complaints caused by routine maintenance issues (filters or spray paths getting restricted) and basic start-up issues (door not fully latched, power supply tripped). The SHE45M05UC owner's manual also highlights simple self-help checks like rinse aid for drying and verifying the door is shut and latched.

Most common issues (and what usually causes them)

• Not cleaning well: restricted sump filter, blocked spray arm holes, heavy soil buildup, or low incoming water temperature.
• Not draining: food debris in the filter area, a kinked/blocked drain hose, or a failing drain pump.
• Not drying: empty rinse-aid dispenser; Bosch condensation drying improves when you crack the door after the cycle.
• Won’t start: door not latched, or a tripped breaker/blown fuse.
• Long cycle times: normal on many Bosch cycles, but can be worse with cooler incoming water or heavy soil.

Quick checks we recommend before replacing parts

1. Clean the filter area and remove any standing debris.
2. Inspect the drain path: sink/disposer connection, air gap (if used), and hose routing.
3. Confirm the door closes firmly and latches every time.
4. Refill rinse aid and use the correct detergent amount for your water hardness.
5. Run hot water at the sink for 30 to 60 seconds before starting a cycle.

Parts that commonly solve real failures

If cleaning and hose checks do not help, these parts are frequent fixes on dishwashers:

Symptom	Common suspect part	Example for this model
Won’t drain or drains slowly	Drain pump or drain restriction	Drain pump 00642239, drain hose 00263099
Poor wash action	Recirculation pump or internal restriction	Dishwasher recirculation pump assembly 00442548, sump filter 00441905
Not filling or fills slowly	Water inlet valve	Dishwasher water inlet valve 00607335

Why it matters

Most “Bosch dishwasher problems” start as airflow, water-flow, or loading issues. Keeping the filter and drain path clear protects the pump system, improves cleaning, and helps prevent repeat clogs and leaks.

On your Bosch dishwasher, the model number is printed on the rating label located on the right edge of the dishwasher door. Open the door and look along the inner right side edge for the label that lists both the model and serial number; see the owner's manual for a diagram.

Where to look (quick steps)

• Open the dishwasher door fully.
• Check the right edge of the door (the vertical edge, not the front panel).
• Find the model and serial number label.
• Copy the model number exactly as shown (letters and numbers).
• Take a clear photo of the label for ordering parts later.

What the label typically includes

Label item	What it’s used for
Model number	Matching parts and diagrams to your exact dishwasher
Serial number	Identifying production details for service records
Other codes	Internal manufacturing information

Why it matters

Bosch dishwashers often share similar-looking doors and controls across model series. Using the exact model number (and sometimes the serial number) ensures you get the correct parts such as a dishwasher water inlet valve 00607335 or drain pump 00642239 that fit and function properly.
