Bosch SHX46A05UC/26 dishwasher Parts

We do not recommend running your Bosch dishwasher model SHX46A05UC with an E22 error because it typically points to a drainage or filter restriction. Running cycles with poor draining can leave dirty water in the tub and can strain the drain system until the blockage is cleared.

What E22 usually means on a Bosch dishwasher

E22 is most often tied to water not moving through the filter and drain path the way it should.

Common causes to check first:

• Food debris blocking the filter area in the sump
• A restricted drain hose (kinked, clogged, or installed with a poor loop)
• A drain pump that is jammed or failing
• Heavy soil buildup that needs a deep clean and maintenance cycle

Quick checks you can do before running another cycle

Turn off power to the dishwasher at the breaker before inspecting internal components.

• Remove and clean the filter area; rinse away grease and debris
• Check the drain hose routing under the sink for kinks or clogs
• Clear the air gap (if your setup has one)
• If you hear humming but no draining, inspect the pump area for obstructions
• If draining is consistently weak, plan on diagnosing the pump and related parts

Parts that commonly relate to E22 symptoms

If cleaning and hose checks do not fix E22, these parts are common next steps for drainage issues:

Symptom	Most likely area	Example part for this model
Standing water after cycle	Drain pump or blockage	Dishwasher drain pump 00642239
Slow drain, intermittent E22	Drain hose restriction	Dishwasher drain hose 00263099
Poor wash plus drainage-related errors	Sump and filter area	Dishwasher fine filter 00441905

Why it matters

E22 is a performance and protection signal. Clearing the restriction restores normal water flow, improves cleaning, and prevents repeated pump strain that can turn a simple clog into a bigger repair.

How we recommend choosing the right replacement part

Use the symptom first, then confirm the match to your exact model variant.

• Match the model number on the rating label to SHX46A05UC (and your version, such as /26)
• Compare the part name and ID to what you are replacing
• Inspect for obvious failure signs (cracks, swelling, burning smell, heavy wear)
• Replace seals and gaskets when replacing pumps to prevent leaks
• After installation, run a short cycle and check for leaks and proper draining

Why it matters

Using model-matched dishwasher repair parts helps restore proper filling, washing pressure, and draining. It also prevents repeat failures, like a new pump leaking because an old gasket or door seal was reused.

Yes, repairing a Bosch dishwasher like model SHX46A05UC is usually worth it when the unit is under about 10 years old and the problem is limited to one failed part (not multiple major failures). In many cases, a targeted repair restores performance for far less than the cost of replacement.

Quick decision checklist

• Age: Under ~10 years old typically favors repair; over ~10 years old favors replacement if multiple issues exist.
• Repair cost: We recommend repairing when the total is under ~50% of the cost of a comparable new dishwasher.
• Failure type: One clear failure (drain, fill, leak) is a good repair candidate.
• Performance history: If it cleaned and drained well before this issue, repair is usually a smart move.
• Condition: Rusted racks, recurring leaks, or repeated electrical issues can push the decision toward replacement.

Common repairs that are often “worth it”

These are typical single-part fixes that can bring SHX46A05UC back to normal operation:

• Not draining: replace the dishwasher drain pump 00642239
• Not filling: replace the dishwasher water inlet valve 00425458
• Leaking at the bottom of the door: replace the dishwasher door seal, lower 00432490
• Poor wash action or weak spray: circulation system service (often the pump and seal)

Cost-to-value guide (simple rule of thumb)

Dishwasher situation	Usually worth repairing?	Why
Under 10 years old, one failed part	Yes	Best value per dollar
Under 10 years old, multiple major parts needed	Maybe	Costs add up quickly
Over 10 years old, major pump or control issue	Often no	Higher risk of follow-on failures
Any age, repeated leaks or electrical problems	Often no	Reliability becomes the issue

Why it matters

A Bosch dishwasher is built around a few high-impact systems (fill, wash circulation, drain, and controls). When one system fails, replacing the specific component usually restores full function without the expense and hassle of a full replacement.

A Bosch dishwasher like model SHX46A05UC typically lasts 10 to 15 years with normal household use. Consistent cleaning, good water quality, and fixing small issues early (like draining or filling problems) are what most often push lifespan toward the high end.

What affects lifespan the most

• Filter and sump cleanliness: food debris left in the filter area makes the pump work harder.
• Water quality: hard water speeds up mineral buildup on internal parts.
• How often you run it: multiple loads daily adds wear to pumps, seals, and the control.
• Proper draining and filling: restrictions strain the drain pump and inlet valve.
• Door sealing and alignment: leaks can damage components and cabinetry.

Quick maintenance checklist (5 to 10 minutes)

• Rinse and clean the filter area regularly; consider replacing a clogged or damaged dishwasher fine filter 00441905.
• Run a dishwasher cleaner cycle periodically to reduce grease and mineral buildup.
• Keep spray arms clear of labels and debris.
• Use the right detergent amount; too much can cause residue, too little can reduce cleaning.
• If you see standing water, address it early using dishwasher not draining video.

Common wear items and what they usually mean

Symptom	Likely area	Example part for SHX46A05UC
Poor cleaning, weak spray	Wash circulation	Dishwasher circulation pump 00442548
Won’t drain, water left in tub	Drain system	Dishwasher drain pump 00642239
Not filling or fills slowly	Water supply	Dishwasher water inlet valve 00425458
Leaks at the bottom of the door	Door sealing	Dishwasher door seal, lower 00432490

Why it matters

Dishwashers usually fail early from restricted water flow, poor draining, or leaks, not from age alone. Keeping the filter path clear and responding quickly to symptoms reduces strain on the circulation pump, drain pump, and control unit.

The most common problems we see with Bosch dishwashers like model SHX46A05UC are not draining, not cleaning well, or not filling properly. In most cases, the root cause is a restriction (filters, sump, hose) or a water-flow part that is wearing out, such as the drain pump or inlet valve.

Most common symptoms and what usually causes them

• Dishwasher won’t drain: clogged filter/sump, kinked drain hose, or a failing pump
• Poor cleaning: clogged fine filter, blocked spray arms, low water flow, or weak circulation
• Not filling or fills slowly: water supply issue or a sticking inlet valve
• Leaks at the door: worn lower door seal or debris on the sealing surfaces
• Stops mid-cycle or acts erratic: control or sensor-related issues

Quick checks we recommend first (no parts needed)

1. Remove and rinse the filter area; clear food and labels from the sump.
2. Confirm the sink drain/disposal is clear and the drain hose is not kinked.
3. Run hot water at the sink for 30 to 60 seconds before starting a cycle.
4. Verify the spray arms spin freely and are not blocked by tall items.
5. Use rinse aid and avoid overloading, especially plastics and deep bowls.

Common parts tied to these problems on SHX46A05UC

Symptom	Likely part area	Example part for this model
Not draining	Drain path/pump	Dishwasher drain pump 00642239
Not filling	Water supply/valve	Dishwasher water inlet valve 00425458
Poor cleaning	Filtration/circulation	Dishwasher fine filter 00441905
Door leak	Door sealing	Dishwasher door seal, lower 00432490

Why it matters

Drain, fill, and wash-performance issues often cascade: a partially clogged filter or weak pump reduces water movement, which leaves soil behind and can trigger longer cycles or stopping behavior. Fixing the restriction early helps protect the circulation system and improves cleaning results.
