Bosch SHE43M02UC/50 dishwasher Parts

We don’t recommend running your Bosch dishwasher model SHE43M02UC with an E22 error because it commonly points to a drainage or filter restriction; continuing to run cycles can leave dirty water in the sump, reduce cleaning performance, and strain the drain system. Use the steps below to clear the cause first.

What E22 usually means on a Bosch dishwasher

E22 is most often tied to water not draining correctly due to a restriction in the filter area or drain path.

Common causes include:

• Food debris blocking the filter and sump area
• A kinked or restricted drain hose
• A partially blocked sink drain or garbage disposal inlet
• A drain pump that is jammed or failing
• Heavy suds from the wrong detergent (can slow draining)

For model-specific display behavior and reset steps, follow the SHE43M02UC manual.

What to do before you run another cycle

Start with the easiest checks first; most E22 issues are resolved without replacing parts.

• Turn off power to the dishwasher at the breaker before reaching into the sump area
• Remove and clean the filter area thoroughly; rinse away grease and debris
• Check the drain hose routing for kinks, pinches, or a low loop problem
• If connected to a garbage disposal, make sure the disposal inlet knockout plug was removed
• Run the kitchen faucet to confirm the sink drain is flowing freely

Quick decision table

What you see	Most likely cause	What to do next
Standing water in the bottom	Drain restriction	Clean filter and check hose path
Humming but not draining	Pump jam or failing pump	Inspect pump area; consider pump replacement
Drains sometimes, not always	Partial clog	Clear hose and sink/disposal connection

Parts that commonly relate to E22 symptoms

If cleaning and hose checks don’t fix it, these model-compatible parts are common next steps:

• Sump filter 00441905 (clogged or damaged filter can restrict flow)
• Drain pump 00642239 (won’t evacuate water if jammed or weak)
• Dishwasher drain hose 00668108 (kinked, restricted, or internally clogged)

Why it matters

A dishwasher that can’t drain properly recirculates dirty water, leaves residue on dishes, and can overwork the drain pump. Fixing the restriction first protects the pump and restores normal wash performance.

To reset a Bosch dishwasher like model SHE43M02UC, we typically cancel the current cycle by pressing and holding the Start button for about 3 to 5 seconds until the unit drains and the indicators change, then we power the dishwasher off and back on to restart normally. See the SHE43M02UC manual for the exact button sequence for your control panel.

Quick reset steps (most Bosch “Silence Plus” models)

• Press and hold Start for 3 to 5 seconds to cancel/reset the cycle.
• Wait for the dishwasher to drain (you may hear the drain pump running).
• Turn the dishwasher off (or open the door and press Power if your panel has it).
• Wait 10 seconds, then turn it back on.
• Select a new cycle and press Start.

If it still will not reset

These checks solve the most common “stuck” reset situations.

• Make sure the door is fully latched; a weak latch can interrupt cancel/drain.
• Check for standing water and a drain issue; a clogged hose or pump can prevent the cancel cycle from finishing.
• Verify the sink drain/disposal connection is clear (new disposals often have a knockout plug that must be removed).
• If the dishwasher is showing an error, match it to the code list in Bosch dishwasher error codes.

Parts that commonly affect cancel/drain

Symptom during reset	Most likely area	Example part for SHE43M02UC
Hums but will not drain	Drain system	Drain pump 00642239
Drains slowly or backs up	Drain path restriction	Dishwasher drain hose 00668108
Stops when you close the door	Door latch issue	Latch 00166630

Why it matters

A proper reset clears a paused or confused control state and forces a drain, which protects the motor and helps prevent odors from standing water. If the unit cannot complete the cancel/drain step, the problem is usually in the drain path, door latch, or an active error condition.

The most common Bosch dishwasher problem (including the Bosch SHE43M02UC) is poor cleaning caused by restricted water flow, usually from a dirty filter, blocked spray arm holes, or low incoming water temperature. Draining complaints are also very common and are often caused by a clog in the sump or drain path.

Most common issues we see (and what usually causes them)

• Not cleaning well: clogged filter, blocked spray arm jets, overloading, or detergent not dissolving
• Not draining: food debris in the sump, kinked drain hose, or a weak drain pump
• Not filling: shutoff valve not fully open, inlet screen clogged, or a failing inlet valve
• Leaking: worn door seal, loose hose connections, or a misaligned door
• Long cycles or odd behavior: sensor-related wash adjustments or an error code

Quick checks you can do first

Start with these simple steps before replacing parts:

• Clean the filter area and remove any standing debris in the sump
• Spin the spray arms by hand and clear any blocked holes
• Confirm the sink drain and garbage disposal inlet are clear (new disposals often have a knockout plug)
• Verify hot water is available at the sink before starting a cycle
• Check that the drain hose is routed high (high loop) and not kinked

Parts that commonly fix the problem

If cleaning or draining problems persist after basic maintenance, these parts are frequent culprits on dishwashers like this:

Symptom	Common part involved	Example part for this model
Poor cleaning, weak spray	Recirculation pump	Dishwasher recirculation pump assembly 00442548
Not draining, water left in tub	Drain pump or drain hose restriction	Drain pump 00642239 or dishwasher drain hose 00668108
Not filling or fills slowly	Water inlet valve	Dishwasher water inlet valve 00607335
Leaks at the bottom of the door	Door seal	Door seal 00432490

Error codes can speed up diagnosis

If your Bosch dishwasher is showing an error code, use it to narrow the problem to a drain, fill, heating, or sensor issue. We recommend checking Bosch dishwasher error codes and then confirming the troubleshooting steps in the SHE43M02UC manual.

Why it matters

Bosch dishwashers are efficient, so small restrictions (like a partially clogged filter or spray arm) can cause big performance drops. Cleaning the sump filter and confirming proper drain routing often restores normal wash pressure and prevents repeat clogs.
