Bosch SHX3AR72UC/22 dishwasher Parts

We do not recommend running your Bosch SHX3AR72UC dishwasher with an E22 error showing. E22 typically points to a drain or filter restriction, so continuing to use it can leave dirty water in the tub, reduce cleaning performance, and increase the chance of a no-drain situation.

What to do first (safe checks)

• Cancel the cycle and let the dishwasher drain if it will.
• Turn off power at the breaker before reaching into the sump area.
• Remove and clean the filter area in the bottom of the tub (food debris and labels are common causes).
• Check the drain hose routing for kinks or a low loop issue.
• Make sure the sink drain or garbage disposer connection is not blocked.

For model-specific filter removal and cleaning steps, follow the owner's manual.

When E22 usually becomes a parts issue

If the filter area is clean and the dishwasher still struggles to drain, the problem is often in the drain path or drain components.

Common related parts for SHX3AR72UC include:

• Dishwasher drain pump 00631200 (won’t drain, humming, intermittent draining)
• Dishwasher drain hose 00668108 (kinked, restricted, leaking)
• Dishwasher check valve 00611320 (backflow or poor draining)

Quick symptom guide

What you notice	Most likely area to check	What it affects
Standing water after cycle	Filter/sump restriction, drain pump	Draining and odor
Humming but little/no drain	Drain pump or blockage	Cycle stops or ends dirty
Drains slowly	Drain hose routing, check valve	Longer cycles, poor cleaning

Why it matters

E22 is a drainage-related warning; drainage is what clears dirty wash water so the circulation system can spray clean water. Fixing the restriction first protects wash performance and helps prevent repeat errors.

For additional Bosch-specific code context, use Bosch dishwasher error codes.

The most common Bosch dishwasher issue is a wash performance failure caused by water not circulating or not draining correctly. On the Bosch SHX3AR72UC, the most frequent repair paths are cleaning a clogged filter/sump area or replacing a failed pump such as the dishwasher drain pump 00631200.

Quick checks we recommend first

• Reset the dishwasher and start a normal cycle to see if the symptom repeats.
• Clean the filter and check the sump area for debris (glass, labels, food).
• Confirm the drain hose is not kinked and the sink drain/disposal is clear.
• Make sure the spray arms spin freely and the holes are not plugged.
• Verify hot water supply to the dishwasher (poor heating can mimic “not cleaning”).

Common symptoms and the part that often fixes it

Symptom	Most likely area	Part to consider for SHX3AR72UC
Water left in tub	Drain system	Dishwasher drain pump 00631200, dishwasher drain hose 00668108
Poor cleaning, weak spray	Circulation system	Dishwasher circulation pump with heater 12008381, dishwasher turbidity sensor 00611323
Detergent door not opening	Dispenser/door	Dishwasher detergent dispenser assembly 12008380
Door won’t latch or cycle won’t start	Door latch	Dishwasher door lock 00630783

Why it matters

Dishwashers depend on correct fill, strong circulation, and reliable draining. When any one of those systems is restricted or a pump is failing, you can see long cycles, dirty dishes, standing water, or error codes.

Use the manual and error codes to pinpoint the failure

• Follow the cleaning and maintenance steps in the owner's manual.
• If your Bosch is showing a code, match it to the symptom before replacing parts using Bosch dishwasher error codes.

For your Bosch dishwasher, the model number is printed on the appliance ID label, usually on the tub frame where the door closes. Open the door and look along the left or right inner edge of the tub opening; the label lists the model and other ID numbers.

Where to look on a Bosch dishwasher

Check these common label locations first:

• Along the left side of the tub opening (door jamb area)
• Along the right side of the tub opening
• On the top edge of the tub opening (near the latch area)
• On the side of the inner door panel (visible with the door open)
• Near the hinge area on the tub frame

For diagrams and model identification details specific to this series, use the owner's manual.

What you should write down

Bosch labels often include several numbers; capturing the right ones prevents ordering the wrong parts.

Label item	What it’s used for	Tip
Model number (E-Nr)	Identifies the exact dishwasher version	Match it exactly, including any slash suffix
FD number	Production date code	Helpful when variations exist
Serial number	Unique unit identifier	Useful for service records

Why it matters

Bosch dishwashers can have small design changes within the same family. Using the exact model number helps us match correct parts like a drain pump, water inlet valve, or door seal for your SHX3AR72UC.
