Bosch SHE43F12UC/60 dishwasher Parts

Yes, most Bosch built-in dishwashers (including the Bosch SHE43F12UC) are made to fit a standard 24-inch-wide opening, while some Bosch models are compact 18-inch-wide units. For exact cutout and leveling requirements, use the SHE43F12UC installation guide.

What “standard size” means for dishwashers

Most U.S. kitchens are built around a standard built-in dishwasher space. Bosch typically offers two common built-in widths.

• Standard built-in: about 24 inches wide (most common)
• Compact built-in: about 18 inches wide (less common)
• Height and depth vary by installation style (countertop height, flooring, toe-kick)
• Many Bosch units are designed to sit flush with cabinetry when leveled correctly

How to confirm fit for your SHE43F12UC

We recommend verifying the opening and connections before ordering parts or planning an install.

• Measure the cabinet opening width, height, and depth
• Check that the water supply line and shutoff valve are accessible
• Confirm the drain routing (high loop or air gap, depending on local plumbing setup)
• Verify electrical requirements and junction box location
• Follow the mounting and leveling steps in the SHE43F12UC installation guide

Quick fit checklist

What to check	Typical target	Why it matters
Opening width	24 inches	Prevents binding and vibration
Opening height	Adjustable range	Ensures the door seals and racks clear
Drain routing	Proper high loop/air gap	Helps prevent backflow and drain issues

Why it matters

A dishwasher that is slightly too tall, too deep, or not leveled can lead to door sealing problems, leaks, noise, and poor draining. Correct fit also helps protect components like the wash system and drain pump.

The most common Bosch dishwasher problem is a drain-related issue: the dishwasher will not drain fully, leaves water in the bottom, or stops mid-cycle because water cannot move out. On Bosch SHE43F12UC, the first things we check are the filter area, drain hose routing, and the drain pump.

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

• Cancel the cycle and let the unit attempt a drain; listen for the drain pump running.
• Remove and clean the filter area; debris here commonly causes poor draining and odor.
• Check the drain hose for kinks, crushing, or an improper high loop/air gap setup.
• Confirm the sink drain or garbage disposer inlet is not blocked.
• Reduce suds; too much detergent or the wrong soap can contribute to leaks and poor performance.

Common symptoms and the most likely causes

Symptom	Most likely cause	What to do next
Water left in tub	Obstructed drain path	Clean filters; inspect hose routing
Bad odor	Food debris in bottom or near door seal	Clean tub and door seal regularly
Won’t start	Door not latched, delay start, power interruption	Verify latch, reset cycle, check power
Not filling	Water supply restriction or delay start	Confirm water supply is on and unrestricted

Parts that often solve drain and leak complaints

If cleaning and hose checks do not fix it, these model-matched parts are common next steps:

• Drain pump 00642239 (when you hear humming but little or no draining)
• Dishwasher drain hose 00668108 (when the hose is kinked, split, or restricted)
• Door seal 00432490 (when leaks appear at the bottom/front of the door)

Why it matters

Drain problems can also cause odor, longer run times, and poor cleaning because the dishwasher cannot circulate and refresh water correctly. Keeping the filter area and door seal clean helps prevent repeat issues.

We do not recommend running your Bosch dishwasher model SHE43F12UC with an E22 error showing because this code commonly points to a drainage or filtering problem; continuing to run cycles can leave dirty water in the sump and lead to poor cleaning and odors. Use the troubleshooting steps in the SHE43F12UC manual first.

What E22 usually means on a Bosch dishwasher

E22 is most often tied to restricted water flow through the filter area or a drain restriction.

Check these common causes first:

• Food debris clogging the filter assembly in the bottom of the tub
• Standing water in the sump after a cycle
• Kinked, pinched, or partially blocked drain hose
• Drain pump obstruction (glass, labels, seeds)
• Heavy grease buildup from infrequent cleaning

Safe, practical steps to try before running another cycle

1. Turn off power to the dishwasher at the breaker.
2. Remove and clean the filter area; rinse under hot water and scrub with a soft brush.
3. Check the drain path in the sump for debris.
4. Inspect the drain hose routing for kinks and confirm it is not crushed behind the unit.
5. If the dishwasher still will not drain, inspect the drain pump and consider replacing the drain pump 00642239 if it is jammed or noisy.

Quick symptom-to-likely-cause guide

What you notice	Most likely issue	What to do next
Water left in bottom after cycle	Clogged filter or drain restriction	Clean filter and check hose
Humming but no draining	Pump jam or failing pump	Check impeller area; replace pump if needed
Dishes not clean and error appears	Restricted circulation from dirty filter	Clean filter; run a cleaning cycle
Error returns quickly	Ongoing blockage or weak pump	Recheck drain path; test pump

Why it matters

A dishwasher that cannot move water correctly cannot wash or drain correctly. Clearing the filter and drain path protects the wash system, helps prevent odors, and restores normal cycle performance.

To reset a Bosch Silence Plus 44 dBA dishwasher (including Bosch model SHE43F12UC), cancel the active cycle: open the door enough to reach the controls, press and hold the Cancel/Reset buttons for 3 seconds, then close the door and let the cancel cycle finish (about 1 minute). Details are in the SHE43F12UC manual.

Reset (cancel and restart) steps

• Open the door just enough to expose the control buttons.
• Press and hold the Cancel/Reset buttons for 3 seconds.
• Close the door.
• Wait for the dishwasher to complete the cancel cycle (approximately 1 minute).
• Open the door and press ON/OFF.
• Select a new wash cycle and options, then start the cycle.

If you only need to pause the cycle

Use an interrupt instead of a full reset when you are adding an item.

• Press ON/OFF to turn the unit off.
• Wait at least 10 seconds before opening the door further.
• Press ON/OFF again to resume, then close the door.

Quick comparison

What you do	What happens	Best for
ON/OFF (interrupt)	Pauses, then resumes the same cycle	Adding a dish, quick pause
Hold Cancel/Reset 3 sec	Cancels the cycle and runs a short cancel cycle	Wrong cycle, stuck program, full reset

Why it matters

On Bosch dishwashers, a “reset” is a cycle cancel. It clears the current program so the control can return to a ready state and you can start a fresh cycle.
