Bosch SHX33A05UC/22 dishwasher Parts

We do not recommend running your Bosch SHX33A05UC dishwasher with an E22 error because it commonly points to a drain or filter restriction; continuing to run it can leave dirty water in the tub and strain the drain system. Fix the cause first, then restart the cycle.

What E22 usually means on this Bosch dishwasher

E22 is most often tied to water not draining properly due to a blockage in the filter area, sump, drain hose, or drain pump.

Common causes to check:

• Food debris clogging the filter and sump area
• Kinked, pinched, or partially blocked drain hose
• Drain pump jammed by glass, labels, or debris
• Standing water triggering a drain-related fault
• A drain path issue at the sink/disposer connection

Safe steps to try before running another cycle

1. Turn off power at the breaker for safety.
2. Remove standing water (cup or wet/dry vac).
3. Clean the filter area and sump; rinse parts thoroughly.
4. Inspect the drain hose routing for kinks and clogs; confirm a proper high loop.
5. If the dishwasher still will not drain, suspect the pump or a restriction downstream.

• If you suspect a failed pump, check the dishwasher drain pump 00642239

Quick “use it or stop” guide

Situation	What we recommend	Why
E22 appears and water is standing	Stop using it	Prevents overflow risk and pump strain
E22 appears but tub is empty	Do not run another full cycle yet	A partial blockage can worsen
E22 returns after cleaning filter	Move to drain hose/pump checks	Points to a deeper drain restriction

Why it matters

A dishwasher that cannot drain correctly will recirculate dirty water, reduce cleaning performance, and can overwork components like the drain pump and sump system.

The most common issue we see on Bosch dishwashers like model SHX33A05UC is a drain problem: water left in the tub at the end of the cycle. In many cases, the fix is clearing a clogged filter area or a restricted drain path before replacing parts.

What to check first (fast, no-parts steps)

• Cancel the cycle and let the unit drain; listen for the drain pump running.
• Remove standing water (cup or wet/dry vac) so you can inspect the sump area.
• Clean the filter area and remove debris (labels, glass, seeds) that can block flow.
• Check the sink drain/disposer connection for a blockage.
• Inspect the drain hose routing for kinks or a sag that traps water.

Common causes and the parts that match the symptom

Symptom	Most likely cause	Part to consider
Hums but won’t drain	Drain pump jammed or failed	Dishwasher drain pump 00642239
Drains slowly	Drain hose restricted or kinked	Dishwasher drain hose 00263099
Stops mid-cycle or cleans poorly	Weak wash circulation or blockage	Dishwasher circulation pump 00442548

Drying complaints are also common (and often normal)

Bosch dishwashers typically rely on condensation drying, so plastics can stay wet and the tub may look steamy after the cycle. For better results, use rinse aid, avoid overloading, and crack the door after the cycle ends.

Why it matters

Drain restrictions can cause standing water, odors, and poor cleaning because dirty water can recirculate. Catching a clog early also helps prevent drain pump strain and repeat failures.

Your Bosch dishwasher’s model number is on the rating label, usually on the inner edge of the door or the door frame. For this series, you’ll typically see SHX33A05UC plus a slash and two digits (like /22) that identify the version.

Where to look on a Bosch dishwasher

Check these common rating-label locations:

• Top or side edge of the dishwasher door (open the door and look along the inner rim)
• Door frame around the tub opening
• Side wall of the tub near the front (visible with the door open)
• Sometimes behind the toe-kick area (less common)

What to write down (and why)

Record the full identifier so we can match the correct diagrams and parts.

What you see on the label	Example	Why it matters
Model number	SHX33A05UC	Identifies the dishwasher platform
Suffix/version	/22	Ensures the right part fit for your exact version
FD number (if shown)	FD 9xxxxxx	Helps date the unit and confirm revisions

Tips to avoid ordering the wrong part

• Copy the model exactly, including the slash and digits (example: SHX33A05UC/22).
• If the label is worn, take a clear photo and zoom in to confirm characters.
• Use the full model when selecting parts like a pump, valve, or seal.

Why it matters

Bosch often uses the same base model number across multiple revisions; the /22 version can change which circulation pump, drain pump, or door seal fits.
