Bosch SHE3ARF6UC/22 dishwasher Parts

We do not recommend running your Bosch dishwasher model SHE3ARF6UC with an E22 error because it typically points to a drainage restriction (most often a dirty filter area or a drain-path blockage). Clearing the cause first helps prevent poor cleaning, standing water, and repeat shutdowns; see the SHE3ARF6UC manual.

What E22 usually means on a Bosch dishwasher

E22 commonly shows up when the dishwasher senses it cannot drain correctly or the filter area is restricted.

Common causes to check first:

• Filter area is clogged with food debris or labels
• Sump area has standing water and debris around the intake
• Drain hose is kinked, pinched, or partially blocked
• Drain pump is jammed or failing
• Sink drain or garbage disposer connection is blocked

What to do before you run another cycle

1. Cancel the cycle and let the unit attempt to drain.
2. Remove and clean the filters and the sump area.
3. Inspect the drain hose routing for kinks and high-loop/air-gap setup.
4. If the unit still will not drain, inspect the pump area for obstructions.

If you suspect a drain pump problem, the model uses a replaceable dishwasher drain pump 00631200.

Quick decision guide

What you see	Best next step	OK to keep using?
Water standing in tub	Clean filters and check drain path	No
Intermittent E22, drains slowly	Check hose routing and sink/disposer connection	No
Loud humming during drain	Check for pump obstruction; consider pump replacement	No
E22 returns immediately after cleaning	Diagnose drain pump, hose, or control inputs	No

Why it matters

A dishwasher that cannot drain recirculates dirty water, leaves residue on dishes, and can strain the drain pump and circulation system. Fixing the restriction first is the fastest way to restore normal wash performance.

The most common Bosch dishwasher problem is poor cleaning caused by restricted water flow (a dirty filter, blocked spray arms, or hard-water buildup). On the Bosch SHE3ARF6UC, the next most common issues are not draining and not filling, which often trace back to a clog or a failing pump or inlet valve.

Most common symptoms and what they usually mean

• Dishes still dirty or gritty: filter needs cleaning, spray arms clogged, or water temperature too low
• Standing water in the tub: drain path restriction or a weak drain pump
• No water entering: supply issue, kinked line, or a failing inlet valve
• Cycle stops with an error: often related to draining, filling, or sensing water conditions
• Detergent door not opening: dispenser issue or loading blocking the door

Quick checks we recommend first (fast, no parts)

1. Clean the filter area and remove debris from the sump.
2. Spin and rinse spray arms; clear any plugged jets.
3. Confirm the sink drain and garbage disposal inlet are clear (new disposals often have a knockout plug).
4. Run hot water at the sink before starting the cycle to improve wash performance.
5. Use rinse aid and avoid overloading so water can reach all surfaces.

When it’s likely a part problem

If cleaning and loading checks do not help, these parts are common fixes on this model:

Symptom	Common culprit	Example part for SHE3ARF6UC
Not draining	Drain pump or drain hose restriction	Dishwasher drain pump 00631200
Not filling	Water inlet valve or supply restriction	Dishwasher water inlet valve 10023853
Poor wash action	Circulation pump issue	Dishwasher circulation pump with heater 12008381
Detergent door issues	Dispenser mechanism	Dishwasher detergent dispenser assembly 12008380

Why it matters

Bosch dishwashers are efficient, so small restrictions (filters, spray arm jets, drain path) can cause big performance drops. Fixing the root cause improves cleaning, prevents odors, and helps the dishwasher complete cycles normally.

For model-specific operating and care steps, follow the SHE3ARF6UC manual. For fault codes and what they point to, use Bosch dishwasher error codes.

Your Bosch dishwasher’s model number is printed on the appliance’s rating label; on most Bosch built-in dishwashers like model SHE3ARF6UC, that label is on the door edge or the inner door frame. Use the full model number from the label when ordering parts or checking diagrams in the owner's manual.

Where to look on the dishwasher

Check these common Bosch label locations (look for a sticker or metal plate with model and FD numbers):

• Along the top edge of the door (visible when you open the door)
• On the left or right side edge of the door
• On the inner door frame around the tub opening
• Near the lower edge of the door, inside the cabinet opening

What to write down (and why)

For accurate part matching, record the full identification details exactly as shown.

• Model number (example: SHE3ARF6UC)
• Index or suffix (often shown after a slash, such as /22)
• FD number (factory date code used by Bosch)
• Serial number (helps confirm production run)

Quick reference

Label item	What it does	When you need it
Model number	Identifies the dishwasher platform	Always, especially for parts lookup
/Index (such as /22)	Narrows to the exact version	When parts vary by revision
FD number	Indicates production date range	When multiple versions exist
Serial number	Unique unit identifier	Service history and verification

Why it matters

Bosch dishwashers often have multiple revisions under the same base model. Using the complete model and index (for example, SHE3ARF6UC/22) prevents ordering a mismatched part like a control board, door seal, or drain pump.
